探讨经导管动脉栓塞术治疗出血性放射性膀胱炎的疗效及并发症。

2009年2月-2011年10月，收治12例出血性放射性膀胱炎的患者，使用700-1000um或300-500um的明胶海绵颗粒，行经导管髂内动脉或髂内动脉分支超选择性栓塞治疗。

12例患者，共行15次介入术（其中10例患者各行1次，1例患者行2次，1例患者行3次），其中2次避开臀上动脉用700-1000um的明胶海绵颗粒行髂内动脉近端栓塞治疗，13次用300-500um的明胶海绵颗粒行超选择性髂内动脉分支栓塞治疗。12例患者均在每次介入术后三天内肉眼血尿先后停止，术后第四天复查尿常规示尿红细胞定量较前均明显较少。术后所有患者长期随访1-40个月，中位随访20个月。其中1例直肠癌的患者于术后约2月复发出血而共行2次介入术，1例宫颈癌的患者分别于术后第二及第三周复发出血而共行3次介入术，余患者无严重血尿复发。

经导管动脉栓塞术是治疗出血性放射性膀胱炎的一种安全有效的方法。

To investigate the effect and complication of internal iliac artery embolization in the treatment of hemorrhagic irradiation cystitis.

During the period from Feb.2009 to Oct.2011,twenty cases with hemorrhagic irradiation cystitis underwent internal iliac artery or super-selected internal iliac artery branch embolism therapy.700-1000um or 300-500um gelatin sponge particles were used in the surgery.

Twelve cases underwent 15 interentional procedures(ten patients underwent one procedure respectively,one patient underwent two procedures, one patient underwent three procedures).700-1000um gelatin sponge particles were used in two procedures,which was internal iliac artery embolism avoiding the superior gluteal artery. 300-500um gelatin sponge particles were used in thirteen procedures,which was super-selected internal iliac artery branch embolism.The symptom of gross hematuria in twelve patinets stopped within three days after each procedure. Compared with the previous,the urinry erythrocyte quantitative reduced significantly in the fourth day after procedures.Long-term follow-up after 1-40 months,with a median follow-up of 20 months.One rectal cancer patient underwent two interventional procedures because of recurrent bleeding.One cervical cancer patient underwent three procedures because of recurrent bleeding after procedure in the second and third weeks.Other patients did not appear serious hematuria recurrence.

Transcatheter internal iliac artery embolization is a safe and effective method to treat hemorrhagic irradiation cystitis.
