介入法制作犬颅内动脉瘤模型

目的运用介入方法建立犬颅内动脉分叉部囊状动脉瘤模型。方法6条犬全麻后，采用血管内介入方法，用冠状动脉球囊导管扩张右颈总动脉近段，再用可脱球囊于扩张段远端将其栓塞，制作成6个分叉部动脉瘤。分别于术后1、2、3d行DSA检查并切除动脉瘤做病理组织学检查。结果6条犬成功获得6个动脉瘤模型。动脉瘤的平均宽度和平均长度在3d内逐渐减少。结论犬动脉瘤模型较好地模拟了人颅内动脉瘤大小、形态及DSA表现，可用于介入治疗新材料、新技术的实验研究。本动脉瘤模型的建立快速、可靠、可重复性强。

Construct canine intracranial aneurysm model by endovascular technique

Objective To construct canine bifurcation aneurysms suitable for evaluating the exploration of endovascular devices for interventional therapy by endovascular technique.Methods The right common carotid artery of six dogs was expanded with a pliable balloon by means of endovascular technique, then embolization with detached balloon was taken at their originations DAS examination were performed on 1,2,3 d after the procedurse. Results 6 aneurysm models were created in six dogs successfully with the mean width and height of the aneurysms decreasing in 3 days.Conclusions This canine aneurysm model presents the virture in the size and shape of human cerebral bifurcation saccular aneurysms on DSA image, suitable for developing the exploration of endovascular devices for aneurismal therapy. The procedure is quick, reliable and reproducible.
