[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.
