This study used magnetic resonance imaging (MRI) to analyze functional long-term outcome after endovascular repair of blunt aortic injury. ⋯ Functional analysis showed no adverse long-term outcome of the bird beak configuration of stent grafts in the aortic arch after endovascular repair after blunt aortic injury.

Previous reports have documented better outcomes after open abdominal aortic aneurysm (AAA) repair in tertiary centers compared with lower-volume hospitals, but outcome variability for endovascular AAA repair (EVAR) vs open AAA repairs in a large tertiary center using a Medicare-derived mortality risk prediction model has not been previously reported. In the current study, we compared the observed vs predicted mortality after EVAR and open AAA repair in a single large tertiary vascular center. ⋯ Despite treating patients with high preoperative risk status, we report a 10-fold decrease in operative mortality for EVAR and open AAA repair in a tertiary vascular center compared with national Medicare-derived predictions. High-risk patients should be considered for aneurysm management in dedicated aortic centers, regardless of approach.

Randomized Controlled Trial Multicenter Study
Prospective, randomized, multi-institutional clinical trial of a silver alginate dressing to reduce lower extremity vascular surgery wound complications.
Wound complications negatively affect outcomes of lower extremity arterial reconstruction. By way of an investigator initiated clinical trial, we tested the hypothesis that a silver-eluting alginate topical surgical dressing would lower wound complication rates in patients undergoing open arterial procedures in the lower extremity. ⋯ The incidence of wound complications remains high in contemporary open lower extremity arterial surgery. Under the study conditions, a silver-eluting alginate dressing showed no effect on the incidence of wound complications.

Acute pulmonary embolism (PE) is a leading cause of cardiovascular mortality. Systemic anticoagulation is the standard of care, and treatment can be escalated in the setting of massive or submassive PE, given the high mortality risk. A secondary consideration for intervention is the prevention of late-onset chronic thromboembolic pulmonary hypertension. ⋯ Whereas systemic thrombolysis seems to be beneficial in the setting of massive PE, it appears to be associated with a higher rate of major complications compared with catheter-directed thrombolysis as shown in recent randomized trials for submassive PE. The hemodynamic and clinical outcomes continue to be defined to determine the indications for and benefits of intervention. The current review summarizes contemporary evidence on the role and outcomes of catheter-directed therapies in the treatment of acute massive and submassive PE.
