The use of coils in endovascular repair of aortic diseases

Objective To summarize the experience and efficiency of coils in endovascular aortic repair. Methods From September 2008 to December 2013, 48 patients received endovascular aortic repair in combination of coil embolization including abdominal aortic aneurysm in 32 patients, and aortic dissection in 16. Results Coils were successfully implanted in all cases. One patient with ruptured abdominal aortic aneurism (AAA) underwent emergency endovascular aortic repair and died of multiple organ failure the day after surgery. One patient died of pulmonary artery embolization 3 hours after TEVAR. 44 patients were followed up ranging from 7 to 60 months. In AAA group, 25 patients received endovascular exclusion in combination with internal iliac artery embolization, four of them had claudication due to gluteal ischemia but without other severe complications. Post-operative CTA found endovascular thrombosis in aneurysm. In the aortic dissection group, one patient died of pulmonary infection. During the follow up, there was no AAA dissection, and AAA rupture. Post-operative CT confirmed thrombus in cavity. There were no scaffold and coil translocation and surrounding tissue injury. Conclusions Endovascular aortic repair in combination with coil embolization is a complementary treatment to aortic diseases. Key words: Aortic aneurysm, abdominal; Angioplasty; Coils
