Endovascular aneurysm repair is being used increasingly to treat ruptured abdominal aortic aneurysms (RAAAs). Approximately 25% of RAAAs undergo complete circulatory collapse before or during the procedure. Patient survival depends on obtaining and maintaining supraceliac balloon control until the endograft is fully deployed. This is accomplished with a sheath-supported compliant balloon inserted via the groin contralateral to the side to be used for insertion of the endograft main body. After the main body is fully deployed, a second balloon is placed within the endograft, and the first balloon is removed so that extension limbs can be placed in the contralateral side. A third balloon can be placed via the contralateral side and ipsilateral extensions deployed as necessary. This technique of supraceliac balloon control is important to achieving good outcomes with RAAAs. In addition to minimizing blood loss, this technique minimizes visceral ischemia and maintains aortic control until the aneurysm rupture site is fully excluded.
血管内动脉瘤修复术越来越多地用于治疗破裂的腹主动脉瘤(RAAA)。大约 25%的 RAAA 在手术前或手术过程中会发生完全循环崩溃。患者的生存取决于获得和维持肠系膜上动脉球囊控制,直到内植物完全展开。这是通过从股动脉插入鞘支持的顺应性球囊来实现的,股动脉与将要插入内植物主体的一侧相对。在内植物主体完全展开后,将第二个球囊置于内植物内,然后取出第一个球囊,以便将延伸支腿放置在对侧。可以通过对侧和同侧延伸部放置第三个球囊,并根据需要展开。肠系膜上动脉球囊控制技术对于 RAAA 的良好结果非常重要。除了最大限度地减少失血外,该技术还最大限度地减少内脏缺血并保持主动脉控制,直到完全排除动脉瘤破裂部位。
