In PAOD, several vascular regions are usually affected [5], the pelvic axis in 35 % of cases. Interventional-radiological/endovascular or hybrid interventions have been established for recanalization, so that bypass procedures are increasingly taking a back seat, but are not losing their importance. Objective: To study unilateral iliac artery occlusions (inclusion criterion) that were repaired either by implantation of an orthotopic or extraanatomic bypass (oBP / eaBP).

The study method was not explicitly based on the STROBE criteria, but essentially corresponds to them. Over a defined period of time, the rate of open vessel, complications (frequency, type, severity) to characterize morbidity and mortality as well as the extent of clinical improvement after BP implantation were analyzed in a clinical-systematic, single-center observational study (for vascular surgical quality assurance and contribution to vascular medical-clinical health care research).

Over 10 years, 122 PAOD patients (50 % in stage IIb - stage III and IV equally distributed; mean age: 63 [range, 44 -87] years; majority ASA III) were included with the same number of reconstructions: 71 patients received an eaBP ("cross over"), 51 patients an iliaco-femoral (orthotopic - oBP) bypass (neither significant difference regarding frequency nor number of risk factors per patient).

The oBP is not superior to eaBP with regard to the analysis parameters of openness, complication rate and mortality. Furthermore, extraanatomic revascularization does not have to be reserved for polymorbid patients only.
