    ABSTRACT: The aim of the study is to study contemporary presentation patterns and clinical results in patients undergoing aortofemoral bypass (AFB) surgery. This was a retrospective comparative study. During a 14-year period, 269 consecutive patients (mean age 65 years) underwent AFB. Indications included occlusive disease with severe intermittent claudication (IC) (n = 86), critical limb ischaemia (CLI, n = 97) and aneurysmo-occlusive disease (n = 86). From 2000-07 on, AFB was performed more frequently for occlusive disease with CLI than for other indications (48% vs. 31% before 2000, P = 0.009) and also in women (51% vs. 32% before 2000, P = 0.003), compared to the period before 2000. Thirty-day mortality was reduced during 2000-2007 to 2.4%, compared with 4.3% during 1993-1999, although this difference was not statistically significant (P = 0.73). Morbidity did not change substantially over the study period. Predictors of 30-day mortality included indication (CLI = 4.1% vs. claudication = 1.2% (P = 0.37)) and chronic kidney disease (CKD, serum creatinine > 1.5 mg dl⁻¹) (11.1% vs. 2.9% in normal renal function, P = 0.07), the latter being the single predictor on multivariate analysis (hazard risk 4.2, P = 0.047). Overall 5 and 10-year assisted primary and secondary patency was 95% and 88%, and 99% and 95%, respectively. Survival at 5 and 10 years was 69% and 48%, respectively. Patient age (hazard risk 1.05, P < 0.001), CKD (hazard risk 1.79, P = 0.018) and diabetes (hazard risk 1.56, P = 0.022) were independent predictors of worse long-term survival. Long-term outcome did not change over the course of the study. In the contemporary era, AFB is more likely to be performed for CLI and in women than in the past. Despite these changes, perioperative mortality and morbidity remain low and long-term outcome excellent.

    ABSTRACT: Recent reports have shown promising early results after endovascular revascularization (percutaneous transluminal angioplasty [PTA]/stent) of patients with peroneal artery-only runoff (PAOR), although the long-term durability is unclear. This study evaluated long-term primary patency and limb salvage of PTA/stent in patients with single-vessel runoff and critical limb ischemia to determine if the peroneal artery yields inferior results. From January 2002 to December 2007, 1075 infrainguinal PTA/stent procedures were performed in 920 patients. The study cohort comprised 201 limbs in 187 patients with single-vessel runoff and critical limb ischemia. End points included primary patency, assisted patency, limb salvage, and survival. Long-term outcomes were determined by Kaplan-Meier life-table and multivariate Cox regression analyses. There were 104 PAOR and 97 limbs with single-vessel posterior or anterior tibial artery runoff (non-PAOR). Median follow-up was 25 months (range, 0-75 months). PAOR patients tended to be older (77.36 ± 0.92 vs 72.65 ± 1.18 years, P = .002) and were more likely to be taking clopidogrel at presentation (88% vs 76%; P = .04). There were no statistically significant differences in 5-year primary patency (26% ± 6.8% vs 30% ± 7.6%; P = .79), assisted patency (75% ± 8.8% vs 81% ± 7.0%; P = .77), limb salvage (74% ± 8.0% vs 75% ± 7.1%; P = .47), and survival (38% ± 7.7% vs 47% ± 6.6%; P = .99) between the PAOR and the non-PAOR groups, respectively. On Cox regression multivariate analysis, total occlusions predicted decreased assisted patency (hazard ratio, 2.99; 95% confidence interval, 1.21-7.41; P = .02), whereas younger age predicted poor limb salvage (hazard ratio, 0.97; 95% confidence interval, 0.94-0.99; P = .04). PAOR was not an independent predictor of any outcome on multivariate analysis. Patients with PAOR have similar long-term outcomes to patients with non-PAOR. Thus, infrainguinal endovascular revascularization can be considered a first-line therapy for patients with PAOR and critical limb ischemia.
