摘要
目的：研究镍钛合金网格内支架修复实验性腹主动脉后壁漏口和重建血管的可行性。材料与方法：５条犬在麻醉后，经股动脉用Ｂｒｏｃｋｅｎｂｒｏｕｇｈ穿刺针和８Ｆ扩张器制成直径２．７ｍｍ的腹主动脉后壁漏口。经８Ｆ导管鞘将１０ｍｍ×６０ｍｍ的镍钛合金密集网格内支架跨漏口植入。结果：５条犬的假性主动脉瘤模型建立均获成功。４条犬的内支架植入位置准确，造影显示漏口闭合、主动脉狭窄改善；３条犬平均于２个月进行了造影随访，均显示腹主动脉及其分支正常。结论：镍钛合金网格内支架能修复实验性腹主动脉后壁漏口和重建主动脉。
Purpose: To explore the feasibility of the mesh stent in treatment of the pathologic leak of abdominal aorta. Materials and methods: The model of posterior wall leak of abdominal aorta was established with modified Brockenbrough needle and 8F dilator catheter via femoral arteries in 5 dogs under anesthesia. The leak was repaired with self made nitinol mesh stents (10 mm in diameter and 60mm in length) delivered by 8F catheter sheaths.Results: The stents were placed across the leak in 4 dogs. Immediate aortogram displayed that the leak was closed and the stenosed aorta was recanalized. Another stent was placed uncovered the leak, and the leak was not closed on aortagram. The follow up aortagram undergone 1, 2, 3 months respectively displayed the normal aorta and its branchs. Conclusion: The preliminary result shows that the mesh stent is feasibility in reparation of the experimental leaks of abdominal aorta and recanalization of vesseles in dogs.
