摘要
目的 建立近似人体的腹主动脉瘤 (AAA)腔内隔绝术 (EVE)后内漏的实验动物模型。方法 采用 6只犬 ,以牛颈静脉间置法或前壁补片的方法形成保留腰动脉的肾下型AAA ,经髂动脉行AAAEVE ,术中采用修剪人造血管和改变支架附着点的方法形成内漏。结果 血管造影示 6只犬动脉瘤形态良好 ,5只犬形成了即时性内漏 ,内漏来自近端返流 ,也有远端返流。结论 通过移植物释放位置的变化可以模拟出与人体EVE后相似的即时性内漏 。
Objective To design an experimental model of endoleak after endovascular exclusion(EVE). Methods Infrarenal aortic aneurysms were created with bovine jugular vein segements or patches. Then they were undergone endovascular stent graft exclusion of the aneurysm. Using modification of prosthetic vessel and changing the attachment site, endoleaks were formed druing the course of aneurysm exclusion. Results All the 6 aneurysms possessed satisfactory configuration just as clinical patterns. Intraoperative arteriography revealed endoleaks in 5 dogs after the exclusion, two of which were proximal and three were distal.Conclusions This experiment shows the hemodynamics and treatment of endoleak for EVE.
