Multicenter Study
Preoperative β-blockers do not improve cardiac outcomes after major elective vascular surgery and may be harmful.
Routine initiation β-blocker medications before vascular surgery is controversial due to conflicting data. The purpose of this analysis was to determine whether prophylactic use of β-blockers before major elective vascular surgery decreased postoperative cardiac events or mortality. ⋯ Exclusive of high-risk open AAA patients, preoperative β-blockers did not decrease rates of MACEs or mortality after LEB, AFB, or open AAA. Importantly, exposure to prophylactic preoperative β-blockers increased the rates of some adverse events in several subgroups. Given these data, the SVS-VQI cannot support routine initiation of preoperative β-blockers before major elective vascular surgery in most patients.

Multicenter Study Observational Study
Morbidity and mortality after use of iliac conduits for endovascular aortic aneurysm repair.
Although placement of an open iliac conduit for endovascular aortic aneurysm repair (EVAR) is generally felt to result in higher morbidity and mortality, published literature is scarce. Our objective was to assess 30-day outcomes after elective EVAR with an open iliac conduit using a multi-institutional database. ⋯ Patients with open iliac conduits for EVAR are more likely to be female and have higher postoperative morbidity and mortality. For patients with complex iliac artery disease, conduits are a viable alternative after EVAR to be performed, albeit at an increased risk. These data do suggest the need for lower-profile grafts and other alternative strategies for navigating complex iliac artery disease.

Multicenter Study
Outcomes of infrainguinal bypass determined by age in the Vascular Study Group of New England.
Many believe extremes of age correlate with poorer outcomes in treatment for lower extremity peripheral arterial disease (PAD). We hypothesized that the youngest patients would have significantly poorer outcomes compared with older cohorts due to the precocious nature of their PAD. ⋯ For patients aged <50 undergoing infrainguinal bypass surgery, this large series demonstrates similar overall medium-term graft-related outcomes compared with older cohorts. Further, although the youngest patients with CLI have similar MALEs, their amputation rates are higher than in older cohorts.
