Outcomes of Endovascular Treatment and Open Repair for Renal Artery Aneurysms: A?Single-Center Retrospective Comparative Analysis

摘要

Abstract Purpose To compare outcomes of endovascular repair and open repair in treatment of renal artery aneurysms (RAAs). Materials and Methods Retrospective analysis included 93 RAAs in 86 patients (56 women; mean age ± SD, 48.8 y ± 12.4) treated from January 2002 to December 2015. Endovascular group comprised 52 RAAs in 45 patients, and operative group comprised 41 RAAs in 41 patients; mean follow-up duration was 49.9 months. Operative variables and perioperative and follow-up outcomes were compared between the 2 groups. Results Endovascular group had shorter operative time (85.2 min vs 270.4 min; P P P P ?= .013) compared with operative group. In-hospital mortality was 0% in both groups. Overall complication rates did not differ between endovascular (22.2%) and operative (19.5%) groups ( P ?= .758). During follow-up, no deaths occurred in either group. Follow-up morbidity was 13.5% for endovascular group and 4.9% for operative group ( P ?= .106). There were no significant differences between groups in average percentage change of estimated glomerular filtration rate (?2.3% ± 12.2 vs??0.8% ± 12.4; P ?= .538), systolic blood pressure (1.7% ± 10 vs??1.6% ± 8.3; P ?= .207), and diastolic blood pressure (?0.2% ± 9.7 vs??1.2% ± 10.4; P ?= .741). Conclusions Endovascular repair and open repair of RAA had similar favorable perioperative and midterm outcomes, but endovascular repair had shorter operative time, ICU stay, hospitalization time, and less estimated blood loss.
