Multicenter Study Observational Study
Routine use of completion imaging after infrainguinal bypass is not associated with higher bypass graft patency.
Significant variability exists in completion imaging (CIM) after infrainguinal lower extremity bypass (LEB). We evaluated the use of CIM and compared graft patency in patients treated by surgeons who performed routine CIM vs those who performed selective CIM. ⋯ In our observational cohort, CIM does not improve short-term and 1-year bypass graft patency in infrainguinal LEB. The surgeon-specific strategy of selective CIM after LEB has outcomes comparable to those of routine CIM.

Comparative Study
Outcomes of endovascular and contemporary open surgical repairs of popliteal artery aneurysm.
The purpose of this study was to compare outcomes after endovascular repair (ER) and contemporary open repair (OR) of popliteal artery aneurysms (PAAs). ⋯ Our study failed to prove the superiority of ER over OR. If anatomy is suitable, ER of PAA in the elderly and high-risk patients is justified. For emergent PAA repairs, MAEs are frequent after both ER and OR; ER has not changed the severe prognosis of acute limb ischemia from PAA. A multicenter randomized controlled trial of PAA patients with acute presentation is warranted.

Comparative Study
A comparison of open and endovascular revascularization for chronic mesenteric ischemia in a clinical decision model.
Open revascularization (OR) has been the treatment of choice for chronic mesenteric ischemia (CMI) for many years, but endovascular revascularization (EV) has been increasingly used with good short-term results. In this study, we evaluated the comparative effectiveness and cost-effectiveness of EV and OR in patients with CMI refractory to conservative management. ⋯ The results of this decision analysis model suggest that EV is favored over OR for patients with CMI in all age groups. Although EV is associated with more expected reinterventions, EV appears to be cost-effective for all age groups.

A right-sided aortic arch is a rare anomaly with an incidence of 0.1% worldwide and is usually associated with a mirror image of all supra-aortic branches or an aberrant left subclavian artery. The latter is often associated with a Kommerell diverticulum, although it can rarely be hypoplastic or atretic and lead to congenital subclavian steal. In most patients, the situation is well-tolerated. In this report, we present a case of subclavian steal syndrome with multiple cerebellar infarcts in a patient with an atypical right-sided aortic arch and an atretic aberrant left subclavian artery arising from a left-sided descending thoracic aorta.
