Multicenter Study Observational Study
Treatment of sac expansion after endovascular aneurysm repair with obliterating endoaneurysmorrhaphy and stent graft preservation.
Persistent type II endoleaks (T2Ls) with sac enlargement after endovascular abdominal aortic aneurysm repair are still of concern in view of the potential for rupture. Current treatments (embolization and stent graft [SG] explantation) are associated with lack of efficacy or high perioperative morbidity and mortality. This study evaluated an alternative technique that combines sacotomy, ligation of patent back-bleeding vessels, and SG preservation for T2L or unspecified endoleak repair. ⋯ Obliterating endoaneurysmorrhaphy with SG preservation can be considered as an alternative to SG removal in cases of persistent T2L responsible for aneurysmal sac enlargement after embolization failure. By avoiding extensive dissection for surgical aortic cross-clamping, minimizing hemodynamic changes, and reducing blood loss and operating time, this procedure can be performed even in patients initially considered unfit for surgery.

Comparative Study
Comparison of open and endovascular treatment of patients with critical limb ischemia in the Vascular Quality Initiative.
There is significant controversy in the management of critical limb ischemia (CLI) arising from infrainguinal peripheral arterial disease. We sought to compare practice patterns and perioperative and long-term outcomes for patients undergoing lower extremity bypass (LEB) and percutaneous vascular interventions (PVIs) for CLI in the Vascular Quality Initiative (VQI). ⋯ In the VQI, PVI was more frequently offered to patients who were older and had more comorbidities, and LEB patients were more likely to have a history of previous interventions. Patients treated with PVI had lower perioperative mortality overall, although this benefit was not seen when treating patients with fewer comorbidities or less advanced disease. However, PVI patients had higher adjusted 3-year mortality in the overall sample and in lower-risk patients. Limitations to this study, especially the follow-up, hamper meaningful interpretation of reinterventions and further reinforce the need for large, randomized, clinical studies with better long-term follow-up.

Comparative Study
Cost analysis of the Hemodialysis Reliable Outflow (HeRO) Graft compared to the tunneled dialysis catheter.
In end-stage renal disease patients with central venous obstruction, who have limited vascular access options, the Hemodialysis Reliable Outflow (HeRO) Graft is a new alternative with a lower incidence of complications and longer effective device life compared to tunneled dialysis catheters (TDCs). We undertook an economic analysis of introducing the HeRO Graft in the UK. ⋯ The base case results showed a marginal net positive cost associated with vascular access with the HeRO Graft compared with TDCs for the incremental clinical benefit of reductions in patency failures, device-related thrombosis, and access-related infection events in a patient population with limited options for dialysis vascular access.

The removal of arterial cannulas using a Perclose device (Abbott Vascular, Clonmel, Tipperary, Ireland) has not been reported in patients undergoing venoarterial extracorporeal membrane oxygenation (ECMO). We investigated the procedural outcomes and complications of percutaneous device closure vs surgical repair for hemostatic control of the arterial access site in weaning from venoarterial ECMO. ⋯ Percutaneous access using two Perclose ProGlide devices was a feasible and safe strategy for weaning from ECMO.
