作者报告121例肾肿瘤行动脉栓塞治疗,使用4种栓塞剂,计明胶海绵、聚乙烯醇海绵、无水乙醇和钢圈。平均并发症率为9.9%,死亡率为3.3%。明胶海绵的并发症最低为5%,聚乙烯醇并发症最高为24%。姑息性栓塞的并发症较术前栓塞者高4倍,最常见的并发症是肾功能衰竭和非靶器官的栓塞。引起肾衰的原因有:①栓塞物逆流至对侧肾动脉,导致对侧肾多发性栓塞;②患者原来有慢性肾衰,操作时使用大剂量造影剂,使肾衰加重。引起非靶器官栓塞的原因有:①栓塞剂逆流至主动脉;②由于肾肿瘤内有较多的动静脉短路,颗粒性梗塞剂从肾动脉注入,经动静脉短路直接流入肾静脉,
The authors reported that 121 cases of renal tumors were treated with arterial embolization using 4 kinds of embolic agents, including gelatin sponge, polyvinyl alcohol sponge, anhydrous ethanol and steel rings. The average complication rate was 9.9% and the mortality rate was 3.3%. Gelatin sponges have a minimum complication of 5% and polyvinyl alcohol complications have a maximum of 24%. The complications of palliative embolism are 4 times higher than those of preoperative embolism. The most common complications are renal failure and embolization of non-target organs. Caused by renal failure are: 1 embolism reflux to the contralateral renal artery, resulting in multiple embolization of the contralateral kidney; 2 patients had chronic renal failure, the use of large doses of contrast agent during operation, so that renal failure. Causes of non-target organ embolism are: 1 embolic agent reflux to the aorta; 2 due to renal artery tumors have more arterial and venous short circuit, granular infarction agent injected from the renal artery, directly through the arterial vein into the renal vein,
