目的

探讨术前经动脉栓塞(preoperative embolization, PE)在椎体转移瘤切除术中的可行性和安全性。

方法

回顾性分析2021年12月至2024年5月在中山大学附属第六医院接受PE的14例椎体转移瘤患者的临床资料及随访结果。分析手术成功率、临床成功率、术中出血量及并发症。

结果

所有患者均成功施行PE。PE术后外科手术切除椎体转移瘤时,椎体转移瘤切除术中出血量(intraoperative blood loss,IBL)为50~1 000 mL,平均(350.0±284.1)mL。根据术中血管造影表现分类,富血管肿瘤患者12例,IBL为395.8 mL;乏血管肿瘤患者2例,IBL为75.0 mL。根据原发肿瘤的组织病理学分类,富血管肿瘤患者2例,IBL为900.0 mL;乏血管肿瘤患者12例,IBL为258.3 mL。术后随访期间未见脊髓梗死、肺炎、褥疮、猝死等严重并发症。

结论

组织病理学上分类的乏血管肿瘤的椎体转移瘤在血管造影上仍可能表现为富血管染色。原发肿瘤的组织病理学类型及肿瘤血管造影的染色程度可能影响IBL。PE可减少椎体转移瘤的外科手术中IBL,是一种安全和有效的治疗手段。

Objective

Preoperative embolization (PE) is an optional method to reduce intraoperative blood loss (IBL) during resection of metastatic vertebral tumors. This study aimed to investigate the efficacy and safety of PE for metastatic vertebral tumors.

Methods

The data for 14 patients with metastatic vertebral tumors who received PE from December 2021 to May 2024 were reviewed retrospectively. The rates of technical and clinical success, intraoperative blood loss, and complications were analysed.

Results

PE was successfully executed in all patients. Mean IBL was 350.0±284.1(50~1 000) mL during surgical resection of vertebral metastases. According to classification of intraoperative angiography findings, 12 cases were hypervascular tumors and 2 cases were nonhypervascular tumors. IBL in hypervascular tumors was 395.8 mL, and in nonhypervascular tumors was 75 mL. According to classification of the primary tumor histopathology, 2 cases were hypervascular tumors and 12 cases were nonhypervascular tumors. IBL in hypervascular tumors was 900 mL, and in nonhypervascular tumors was 258.3 mL. No serious complications, such as spinal cord infarction, pneumonia, bedsore or sudden death, were observed in these patients.

Conclusion

Nonhypervascular tumors classified by histopathology may still appear vascularly rich on angiography in the context of spinal metastases. The primary tumor histopathology and intraoperative angiography may impact the IBL. PE is an effective and safe treatment for metastatic vertebral tumors of reducing IBL during surgery.
