to explore the imaging manifestations of sinusoidal obstruction syndrome (HSOS) caused by Gynura segetum.

A total of 20 cases of HSOS caused by consuming Gynura segetum were confirmed by clinical diagnosis and liver biospy. Including them there are 19 males and 1 female; 12cases confirmed by the liver biospy, 8 cases with clinical manifestations, medical history and lab examinations comprehensive diagnosis. All patients had trauma, stroke history, after taking 10 days to 6 months of clinical symtoms. The clinical data, CT and MR imagings had be analyzed in this article.

A total of 14 cases underwent CT scan and 11 cases accepted MRI examination. Unenhanced CT features are heterogenous hypodensity of liver parenchyma, the portal venous and delayed phases of hepatic enhancement performed uneven and poorly perfusion. The MRI examination can show the liver parenchyma more clearly than the CT scan, the liver parenchyma along the three main hepatic veins appears higher and more even signal than the rest part of the liver. The three main hepatic veins seemed tiny, light or absence, the inferior vena cava became compressed but unobstructed. The periportal edema and portal hypertension also represented.

The HSOS caused by Gynura segetum have a certain degree of typical imaging findings. The CT and MRI examination have a important role in the review and evaluation of clinical efficacy. The MRI examination can better assess the liver parenchymal damage and intrahepatic venous situation, the imaging postprocessing technique of CT can clearly show the inferior vena cava and intrahepatic vessels. These two examination have important effect in diagnosis and differential diagnosis of HSOS, combing with Gynura segetum consuming history and pathological examination, can help to suggest the diagnosis of HSOS.

To investigate the clinical effects of abdominal aortic balloon occlusion followed by uterine artery embolization in the treatment of pernicious placenta previa complicated with placenta accrete during cesarean section.

A retrospective analysis of clinical data of 512 patients who suffered from pernicious placenta previa complicated with placenta accreta and received treatment in our hospital from January 2013 to December 2016 was carried out. All patients underwent abdominal aortic balloon implantation before cesarean section. 62 patients received bilateral uterine artery embolization, among them, the placenta accreta was found at the opening of the cervix in 4 cases. Due to the difficulty to suture after the removal of the placenta, gauze packing was used to compress hemorrhage temporarily. As soon as the uterus was sutured, emergent bilateral uterine artery embolization was performed. In the other 58 cases, there was still active bleeding when pressing the lower part of the uterus after the placenta was removed and the uterus was sutured, so bilateral uterine artery embolization was performed urgently. This study aims to investigate the clinical effects and complications of the 62 patients who received abdominal aortic balloon occlusion followed by uterine artery embolization.

Of all 512 patients, 450 patients received only abdominal aortic balloon occlusion; 62 patients underwent emergent bilateral uterine artery embolization additionally due to hemorrhage during or after the C-section. No hysterectomy was performed. Of the 62 patients, the amount of bleeding was 900~3 000 ml with an average of 1500 ml during the operation; the volume of blood transfusion was 350~1 600 ml with an average of 940ml. Fetal fluoroscopy time was 3~8 s with an average of 5 s. The dose of received radiation exposure was (4.2±2.9)mGy. Fetal Apgar score was normal. No serious complications were observed during and after the operation in follow-up visits.

For patients with pernicious placenta previa complicated with placenta accreta and suffering from active bleeding after cesarean section and abdominal aortic balloon occlusion, bilateral uterine artery embolization can effectively reduce blood loss and blood transfusion during the operation, as well as lower the risk of hysterectomy.

This study compares the clinical effect of uterine artery chemoembolization (UACE) and uterine artery embolization (UAE) in treating cesarean scar pregnancy.

71 patients who were diagnosed with cesarean scar pregnancy (CSP) at the First Hospital of Shanxi Medical University between January 2007 and May 2016 were enrolled in this study. These patients were divided into two groups: Group A (33) and Group B (38). Group A received UACE prior to curettage 24-48 hours later while Group B received UAE prior to curettage 24-48 hours later. The hemorrhage volume during the curettage, the time for β-HCG reduced to normal and hospital stays were compared between the two groups.

Both groups received satisfactory results. The bleeding during the curettage was recorded as - Group A (40±30) ml, Group B (50±20) ml, thus, there was no significant statistical difference. The time for β-HCG reduced to normal: Group A (16±3) d was less than Group B, which was (21±5 ) d, there was a statistical difference . Hospital stays: Group A (11±3) d also had less stays than Group B (13.5±4.5) d, as showed a statistical difference.

UACE and UAE did not have statistical significance in terms of bleeding during curettage and success rate, however, UACE can shorten the time of β-HCG reduced to normal and hospital stays.

This paper is to analyze the outcome and risk factors of interventional therapy for lower extremity deep venous thrombosis.

From July 2012 to June 2015, 65 patients (27 men and 38 women) underwent interventional therapy for deep venous thrombosis of lower extremity. 16 patients underwent conservative therapy, 23 patients underwent catheter-directed thrombolysis, 26 patients underwent mechanical thrombolysis plus catheter-directed thrombolysis.

Follow up duration are 1 to 30 months. During the follow up duration, 13 patients replase or fail treated, the cured rate was 80.0%. The average hospitalization time is 16.2 d.The result of single factor study and logistic regression analysis show that the treatment methods and the stages of thrombosis are the prognosis factors. Multivariate multiple linear regression analysis show that the stages and location of thrombosis, and the filter influence the duration of hospitalization.

The treatment methods and the stages of thrombosis influence the prognosis of DVT with thrombolysis therapy. The stages ,locations of thrombosis and the filter will influence the duration of hospitalization.

To evaluate the clinical and imaging characteristics of vertebral-basilar dissection aneurysm (VBDA).

A retrospective review of 57 cases of VBDA patients between Jan 2008 and Mar 2014 in our hospital was performed. The clinical manifestation, the DSA findings, positive CT/MRI and CTA/MRA results was analyzed.

Hemorrhagic stroke was identified in 28 cases (49.1%), ischemic stroke in 20 cases (35.1%), cervical occipital neuralgia in 5 cases (8.8%), asymptomatic in 4 cases (7%). The most common clinical symptoms were headache (59.6%), nausea and vomiting (54.4%), dizziness (42.1%), cervical occipital pain (26.3%). Diagnosis was confirmed by DSA in 55 cases among 55 cases, by CTA in 7 among 33 cases, by MRA in 1 among 8 cases; by high resolution MR in 4 among 4 cases. The most common sign of DSA, CTA and MRA is bead syndrome (67.3%) and rat tail sign (25.5%). The most common type is the saccular aneurysms, with fusiform aneurysm and parent artery abnormal thickening as less common signs.

SAH is the most common onset syndrome of VBDA, while other common clinical signs include post-circulation ischemia or infarction. DSA is the most valuable imaging exam for VBDA, and high resolution MRA is a diagnostic method with great potential.

For those who have not appropriate surgical removal of the middle-late hepatocellular carcinoma(HCC), simply by transcatheter arterial chemoembolization(TACE) with conventional treatment can not obviously improve the prognosis of patients.The emergence of molecular targeted drugs to treat hepatocellurlar carcinoma provides a new idea. Molecular targeted drugs in the treatment of HCC clinical trails including multiple targets inhibitors, and the targeted molecular medicine combined with TACE has shown the potential curative effect and good prospects for development.We summarize the using multiple targets inhibitors, vascular endothelial growth inhibitor combined with TACE to HCC.

To investigate interventional therapy value in the acute gastrointestinal arterial hemorrhage.

Date of 75 patients with arteriography for the acute gastrointestinal hemorrhage was retrospectively analyzed, and cases in which the shock index<1 were divided as group A, the shock index ≥1 as group B. Comparative analysis of the positive detection rate were made in the two groups. Cases using coil to embolize prescribed as group C, and cases with gelatin sponge coil embolism prescribed as group D. Comparative analysis of recurrence rate were made in these two groups .Factors affecting the positive detection rate, recurrence of bleeding and severe complications were analyzed in the end.

Positive detection rate of 75 cases was 56% (42/75), and it has statistic significance of positive detection rate in group A and B (P <0.05). All 42 patients with contrast positive took the interventional embolic treatment, for technical success rate was 100%. Recurrence rate of bleeding in group C and D has no statistic significance (P>0.05). Two cases of intestinal ischemia necrosis showed in these two groups. Three patients with negative results of DSA examination were found re-bleeding after radiography, whereas interventional therapy was done at the same time.

Interventional embolization is one of the vital methods in treatment of gastrointestinal arterial hemorrhage, not only can clarify diagnosis, but also save patients life promptly. Interventional therapy therefore should be done as soon as possible when patients diagnosed as gastrointestinal hemorrhage.

To explore the methods and clinical effect of endovascular interventional therapy for diabetic foot.

48 patients with diabetic foot treated in our hospital from January 2014 to January 2016 underwent endovascular interventional therapy accordingly.

In the 48 patients, the lower extremity arterial angiography showed a total of 62 stenosis lesions, among which, the middle and lower femoral artery and the popliteal artery showed the highest rate (53.2%) of stenosis. Accordingly, 20 patients underwent endovascular stenting and the other 28 patients (P <0.01) underwent percutaneous transluminal balloon angioplasty. In the follow up after six months of the treatment, the ankle-brachial index (ABI) was significantly higher than that before the treatment (P <0.01), and their clinical symptoms were improved significantly (0.80 ± 0.03 vs. 0.56 ± 0.02). No vascular restenosis or occlusion were observed , the wounds were effectively repaired.

Endovascular interventional therapy is a safe and effective strategy in treating diabetic foot. It can be applied on multiple lesions and repeated as an efficient strategy yet with less complications, thus, it has high clinical value.

To evaluate the clinical effect and feasibility of loxoprofen sodium in efficiently alleviating the pain after uterine artery embolization (UAE) pain.

Twenty-four patients with uterine fibroids treated with UAE in our hospital between January and August in 2016 were selected for this study. They were randomly divided into observation group (n=12) and control group (n=12). The observation group were treated with loxoprofen sodium 60 mg/time and 3 times/day while control group received an oral administration of loxoprofen sodium 60 mg / ?. The visual analogue scale (VAS) of the two groups at different time (0,4,8,16,24,48 h) was compared to evaluate the degree of the pain. The comfort degree was evaluated by Brinell comfort score (BCS).

The VAS scores of the observation group were significantly lower than those of the control group at 0, 4, 8, 16, 24 and 48 h after operation (P <0.01). The BCS scores of 0,4,8,16,24,48 h of the observation group were significantly higher than those of the control group (P <0.05).

The loxoprofen sodium can greatly reduce the degree of postoperative pain of UAE and improve the comfort and satisfaction of patients, thus, it is worth of clinical application.

To explore effect of percutaneous transhepatic insertion of biliary stent implanted with radioactive seeds in treatment of alignant biliary obstruction.

¹²⁵I seed, each of which was 4.5 mm in length and 0.8 mm in diameter, was applied in 38 patients with malignant biliary obstruction. They were led to a catheter for preparing ¹²⁵I seed sliver. The patients were given percutaneous transhepatic cholangial drainage (PTCD) at the first step; then a percutaneous puncture was done through the obstructed section by a guide wire. The patients were given balloon catheter dilatation therapy before percutaneous transhepatic insertion of biliary stent (PTIBS). Biliary drainage catheter with the size of 8—10F were implanted. Finally the catheter with ¹²⁵I seeds sliver was sent to the part to be radiated via the biliary drainage catheter and the exposed part of the biliary drainage catheter which stretched outside the patients’ body was wrapped or imbedded beneath the skin.

Among 38 patients, the successful implementation of PTIBS and radioactive seed implantation treatment in 36 cases. All these patients had their bilirubin values return to or very close to normal level (P<0.05). No obvious side effect was obsreved.

PTIBS combined with radioactive seed implantation therapy in treatment of malignant biliary obstruction is safe and effective.

To evaluate the safety and clinical short-term efficacy of interventional embolization with CalliSpheres-loaded microspheres in treating advanced hepatocellular carcinoma.

A total of 25 patients with advanced hepatocellular carcinoma underwent transcatheter arterial chemoembolization (TACE) plus using CalliSpheres-loaded microspheres treatment. The clinical and imaging data, complications of interventional treatment and prognosis were summarized and analyzed by modified response evaluation criteria in solid tumors (mRECIST); follow-up was performed on all patients.

The follow-up lasted 6 months. According to mRECIST, the 3-month objective response rate (CR+PR) was 80% and disease control rate (CR+PR+SD) was 88%; the 6-month objective response rate (CR+PR) was 72% and disease control rate (CR+PR+SD) was 80%. At day 3 after the procedure, the levels of ALT, AST and TBIL were increased, with a statistical significance compared with those before the operation. However, there was no significant difference in the level of albumin. At 3 months postoperatively, the indications of liver function returned to the normal level. And there was no significant difference between pre- and post-operation. No severe complications, such as bile leak with infection, liver abscess, abdominal hemorrhage, bleeding due to tumor rupture and gastrointestinal bleeding occurred in these patients.

TACE performed with CalliSpheres-loaded microspheres is a novel and safe option for patients with advanced hepatocellular carcinoma. Its clinical short-term efficacy was satisfied, yet its long-term efficacy needs further studies.

To evaluate the clinical efficacy of bronchial artery embolization (BAE) using combination of Embosphere microspheres and mechanical coils in treatment of massive hemoptysis.

During the period from October 2014 to January 2016, a total of 52 patients with massive hemoptysis who had failed to respond to medical management received BAE, among these, the clinical efficacy of massive hemoptysis patients treated with Embosphere microspheres (n=25, group EM) was compared with those treated with combination of Embosphere microspheres and mechanical coils (n=27, group MC) . All patients were followed up for 1 year.

BAE was successfully accomplished in all 52 patients with an effective rate of 96.15% for bleeding-cessation within 24 h. In each group there was 1 case of hemoptysis, without statistical significance (P>0.05) . Recurrence of hemoptysis within 1 year after BAE was seen in 9 patients (nEM=7, nMC=2, 8/52, 17.31%) . Recurrence of hemoptysis within 3 months after BAE was found in 1 patient in both EM and MC groups (P>0.05) . MC group had a lower recurrence rate than EM group during the follow-up period of 3~12 months after the procedure (3.7% vs 24%, P<0.05) .

Combination of Embosphere microspheres and mechanical coils can efficient improve the metaphase and long-term efficacy of BAE, and reduce the recurrence of hemoptysis.

To investigate the clinical effects of painless uterine artery embolization on uterine leimyoma.

From January 2013 to June 2014,interventional therapy was performed on 48 patients withuterine leimyoma,puncture right femoral arteryand under the guidance of DSA. The 4F or 5F Cobra catheter was placed into iliac artery then into uterial arteries with 710 - 1000 μm PVA as embolization agent.

The operation was completed successfully in all patients, with the technical success rate 100% (48/48). Normal menstruation was observed in 46 cases 6 months after the procedures.Anemia disappeared in 26 out of 28 cases during the 6 months follow up. The volume of leiomyoma shrinkage obviously in 33 cases while disappeared in 2 cases.

Painless uterine artery embolization is effective in the treatment of uterine leiomyoma, with no serious complications.

To observe the clinical value of emergency angiography and embolism therapy for acute massive gastrointestinal hemorrhage.

A total of 49 cases of acute massive gastrointestinal hemorrhage, who had symptoms of shock, received emergency angiography. After verifying the bleeding site, the supply arteries were embolized with polyvimnyl alcohol (PVA) particle, Gelatin Sponge particle or coils.

Among the 49 patients, all cases were identified of the bleeding site, 47 cases were successfully embolized of the supply arteries, 1 case received emergency open surgery instead, 1 case neither received arterial embolization nor the emergency surgery treatment because of the critical condition, and died subsequently. The total procedure effective rate was 95.92% (47/49). The patients, who were successfully embolized, never manifested bleeding or severe complications again during the hospitalization, and were discharged with cure. The average hospitalization time was 15 days. While the patients who received emergency surgery was discharged till 2 months after the operation.

Emergency angiography has a high diagnostic accuracy for acute massive gastrointestinal hemorrhage. Arterial embolization is an effective and minimal invasive approach with remarkable cure rate, which can alleviate the suffering of patients not only physically but also psychologically.

原发性肝癌是世界上最常见的恶性肿瘤之一,经导管动脉化疗栓塞术（TACE）已经成为公认的肝癌非手术治疗的首选方法。碘油是目前临床治疗肝癌最常用的栓塞剂，微球是一种新型的末梢栓塞剂，近年来，有学者认为微球栓塞延长肝癌患者的生存率，而且毒性较小，其临床疗效优于应用碘油的传统TACE；然而，另一些学者则认为传统碘油栓塞更具优势。本文就这两种栓塞剂研究进展及其疗效对比加以综述。

To investigate the clinical effect of interventional therapy for uterine fibroids.

A retrospective analysis of interventional radiology and gynecological January 2013 to June 2014 for interventional treatment of 60 cases of patients with uterine myoma in our hospital, respectively in the preoperative and postoperative 3, 6 and 12 months determination and the volume of myoma and uterine volume, anemia patients hemoglobin concentration determination.

The success rate of operation was 100% (60/60), compared with the preoperative, patients in the postoperative uterine fibroids volume and uterine volume decreases, the rate of anemia in patients with hemoglobin rise, the difference was statistically significant (P < 0.05).In patients with decreased menstruation, menstrual recovery, other clinical symptoms have varying degrees of ease, no serious complications occurred.

Interventional treatment of uterine fibroids can retain the uterus, the effect is obvious, the curative effect is remarkable, is worth in clinical promotion.

To investigate the nosocomial infection in hospitalized patients with acute myocardial infarction and provide preventive strategies to reduce the incidence of such infection.

A retrospective review of the clinical data of 412 patients with acute myocardial infarction during Feb 2013 to Sep 2016 was analyzed with Logistic method.

The incidence of nosocomial infection in these patients was 16.3%(67/412), with the respiratory tract infection (50.7%, 37/67) the most common occurrence. Nosocomial infection was observed in relation with many factors, including the patient's age, time of treatment, dysfunction of the left ventricular heart, complication of COPD, and other inflictions such as diabetes, liver and kidney dysfunction. In addition, the duration of hospitalization andProphylactic use of antimicrobial agents also played a role in the infection.

The incidence of the nosocomial infection is a common occurrence in the hospitalized patients with acute myocardial infarction, it is necessary to take corresponding preventive countermeasures against the related risk factors in order to reduce and control the infection, and to improve the survival quality of patients with acute myocardial infarction.

To investigate the efficacy of uterine artery embolization (UAE) in preventing acute massive hemorrhage caused by uterine curettage with cesarean scar pregnancies (CSP).

20 cases of cesarean scar pregnancy admitted into our hospitals from January 2013 to December 2015 were selected in this study. All the 20 patients were treated by UAE. Then the therapeutic effect of UAE on cesarean scar pregnancy was observed.

20 patients were all successfully treated with UAE, and the curettage procedures were performed in next 48~72 h. Intraoperative blood loss was about 30~150 ml. Pathological examinations detected villi tissue after curettage. The β-HCG value resumed to normal levels in 10~29 d, with an average of (16.7±4.5)d. There were no hemorrhage observed in the follow-up of 3~6 months later.

UAE is an effective therapeutic method in preventing acute massive hemorrhage caused by uterine curettage with CSP. It is easy to manipulate with evident benefit to patients, thus is worthy of clinical application.

Compare the clinical outcomes of dilation and curettage (D&C) after uterine artery chemoembolization (UACE) and laparotomy lesion excision for treatment of cesarean scar pregnancy.

77 Patients with cesarean scar pregnancy between January 2009 and January 2012 were enrolled for retrospective analyses. The patients were divided into two groups: 22 patients in group A treated by laparotomy lesion excision; group B included 55 patients, who received UACE 24-72 hours before D&C. The main outcome measures were operation time, blood loss, time for β-human chorionic gonadotrophin (β-hCG) to decline to normal values, the duration of hospital stay, rate of secondary treatment, complications and menstrual situation after operation.

None of the 77 patients received hysterectomy. In group A, 1 patient had to receive uterine artery embolization due to massive hemorrhage. The rate of secondary treatment was 5% in group A. In group B, 1 patient received perforation repair, 1 received laparotomy lesion excision due to active bleeding. Theβ-hCG level persisted in 3 patients, 2 of them received MTX injection and 1 received D&C again. The rate of secondary treatment was 9% in group B. The operation time in group B was less than that in group A (35.35±20.21) min versus (114.45±34.32) min, P <0.01). The mean blood loss in group B was lower than that in group A (52.36±28.04) ml versus (186.53±43.30)ml, P<0.01). The average time for β-hCG to decline to normal had significant different between two groups (15.32±3.21)d in group A versus (24.11±7.32) d in group B, P <0.01). The duration of hospital stay of group B was less than that of group A(13.46±4.87) days versus (19.34±5.72) days, P<0.01). All patients regained normal menstruation within half a year.

D&C after UACE and laparotomy lesion excision are both safe and effective treatments for CSP. D&C after UACE is minimally invasive, with less operation time, less duration of hospital stay and less blood loss in operation. Especially, UACE could provide remarkable clinic outcomes for the patients with acute vaginal bleeding.
