    From 2001 to 2012, arterial reconstruction was performed in 306 out of 497 limbs (62%) with critical limb ischemia. The reasons for non-vascularization include high operative risk (36%), extended necrosis or infection (20%), and technical issues (15%). Cumulative patency and limb salvage in collagen disease were significantly worse compared to arteriosclerosis obliterans. Cumulative limb salvage, amputation free survival (AFS), and major adverse limb event and perioperative death (MALE+POD) in patients with end-stage renal disease (ESRD) were significantly worse compared to patients without ESRD, but not significant with regards to graft patency. Our finding suggests that aggressive arterial reconstruction provides satisfactory long-term results in critical limb ischemia so long as case selection for revascularization is properly made.

    Whether endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is a relative contraindication in patients with preoperative renal dysfunction (Pre-RD), remains controversial because the contrast medium may induce nephrotoxicity. In this study 1658 patients were treated at 10 Japanese medical centers between January 2005 and March 2011 (Open surgery (OS) vs. EVAR: n=1270 vs. n=388). They were retrospectively analyzed. Multiple logistic regression analysis (MLRA) with pre- and intra-operative variables was applied to all patients. The endpoints induced onset of new dialysis and postoperative renal dysfunction (Post-RD), were defined as a 50% decrease or more from the preoperative eGFR level. Results: Early mortality, Post-RD, incidence and new dialysis in all patients were 1.6% (OS : EVAR = 1.9% : 0.8%), 6% (OS : EVAR = 8% : 2.3%) and 1.4% (OS : EVAR = 1.5% : 1.0%) respectively. MLRA identified operation time, clamp of renal artery as risk factors for Post-RD, and operation time and Pre-eGFR level as risk factors for new dialysis. Conclusion: Although Post-RD was more frequently observed in the OS group, MLRA showed that the choice of OS or EVAR was not a risk factor for Post-RD and new dialysis. Using contrast medium during EVAR often may not be a contraindication to AAA repair in patients with Pre-RD.
