Endovascular stent graft therapy of abdominal aortic aneurysms is sometimes complicated due to unusual anatomy of the aorta and adjacent arterial regions, an irregular or short proximal neck, numerous patent branches originating from the aneurysm, or tortuous iliac arteries. Endovascular aneurysm sealing is a new method designed to overcome certain limitations of current stent grafts.
At the Department of Vascular Surgery of Na Homolce Hospital, we implanted 51 stent grafts in the subrenal aorta and iliac arteries. Most of them were regular bifurcated stent grafts. Two patients were treated with the new Nellix stent graft, in one case due to a short subrenal neck of only 13 mm, and due to a considerably conical neck in the second case.
The post-operative course was uneventful in both patients and they were discharged on the 5th postoperative day. CT angiography after six weeks proved that the stent graft had sealed well. The polymer filled the aortic lumen completely.
This new method of endovascular aneurysm sealing (EVAS) of abdominal aortic aneurysm makes it possible to treat patients whose anatomy would normally require technically complex and more expensive endovascular methods. We aim to follow long-term results of the method in larger patient cohorts.
腹主动脉瘤的血管内支架植入治疗有时会因主动脉及相邻动脉区域的特殊解剖结构、近端颈部不规则或过短、动脉瘤发出众多分支血管或髂动脉迂曲而变得复杂。血管内动脉瘤封堵术是一种旨在克服当前支架植入局限性的新方法。
在纳霍姆采医院血管外科，我们在肾下腹主动脉和髂动脉植入了51个支架。其中大部分是常规分叉型支架。两名患者接受了新型Nellix支架植入治疗，一例是因为肾下颈部过短，仅13毫米，另一例是因为颈部呈明显锥形。
两名患者术后恢复均顺利，术后第5天出院。六周后的CT血管造影证实支架封堵良好。聚合物完全填充了主动脉管腔。
这种腹主动脉瘤血管内动脉瘤封堵术（EVAS）的新方法使得治疗那些解剖结构通常需要技术复杂且成本更高的血管内治疗方法的患者成为可能。我们旨在追踪更大患者队列中该方法的长期效果。
