Two Methods of Internal Iliac Artery Exclusion in Endovascular Aorta Repair: a Middle-long Term Follow-up Study

Objective To compare the middle and long term results of two internal iliac artery exclusionmethods (with or without coils) in endovascular aorta repair (EVAR). Methods Clinical data of patients who underwent EVAR from January 2006 to December 2013 were analyzed retrospectively. The participants were divided into two group: coils were not used in Group A, but were used in Group B. The patients were followed up from June 2006 to June 2014. Results A total of 137 patients (74 in Group A, 63 in Group B) were included in this study, with a mean age of 71.6 years. The majority (124) of participants were men. Postoperative 30-day mortality of the participants was 0.73%. None of the participants developed pelvic and spinal ischemia. Claudication appeared in 9 patients (3 in Group A and 6 in Group B). Ischemia in lower extremity happened in 5 patients (2 in Group A and 3 in Group B).Gluteal sore was reported by 5 patients (1 in Group A and 4 in Group B). One patient from Group B developed gluteal skin necrosis. No statistical difference in ischemia and stent occlusion was found between the two groups (P=0.301, P=0.108). However, patients in Group B stayed in hospitals longer (P<0.001) than those in group A. One patient in Group B developed severe ischemic complication:skin and gluteus necrosis. Conclusion Internal iliac artery exclusions with and without coilsresult in similar middle and long term outcomes measured by ischemic complications.
