Abstract
eGFR and three patients required hemodialysis. Five patients had full recovery of renal function by discharge. In hospital, 30-day morbidity/ mortality were 25%/3% respectively. At a mean follow-up of 3 years, six patients had an eGFR significantly less than the preoperative value. Late interventions related to the AAA repair were required in eight patients. Indications included: wound complication (3), anastomotic aneurysm (2), incisional hernia (1), anastomotic graft stenosis (1), and proximal aortic dilatation (1). Overall 5-year intervention free survival was 61% and overall survival 79%. Intervention free survival was decreased by perioperative pneumonia (P 1⁄4.01) and enhanced by antiplatelet (P 1⁄4 .05) use whereas overall survival was decreased by COPD (P 1⁄4 .03) and perioperative pneumonia (P 1⁄4 .001). Conclusions: A quarter of patients requiring a suprarenal cross-clamp during open AAA repair experience renal dysfunction. Late graft related complications are few with preoperative and perioperative pulmonary function negatively impacting intervention-free and overall patient survival.
