The urgent treatment of ruptured abdominal aortic aneurysms (rAAA) remains a challenging condition with devastating morbidity and mortality. Available studies are often limited due to a significant selection bias. This study aims to illuminate real-world evidence using comprehensive data from electronic health records, registries, postmortem findings, and administrative data on all consecutively treated patients presenting with rAAA at a tertiary care center. ⋯ We observed comparable outcomes following OSR and EVAR, although hemodynamically unstable patients were more likely to be treated by OSR. This study also confirmed the impact of colonic ischemia as a devastating complication following rAAA repair emphasizing the need for further reflection by the vascular community.

Mentoring relationships have been encouraged for medical students interested in surgical specialties. We investigated the role of mentoring relationships of integrated vascular surgery residents, while in medical school. We hypothesized that mentoring relationships between medical students and vascular surgeons would have a positive effect on match outcome in the integrated vascular surgery residency match. ⋯ Integrated vascular surgery residents were generally positive about their medical school mentors. Our data indicate that surgical mentorship in medical school is effective, both in influencing medical students to choose the vascular surgery specialty and in improving match rank-vascular surgeons were more knowledgeable and mentees with vascular surgeon mentors tended to be more successful in the match.

Comparative Study
Transfusion Timing and Postoperative Myocardial Infarction and Death in Patients Undergoing Common Vascular Procedures.
Perioperative allogenic blood transfusions, specifically packed red bloods cells (pRBC), after vascular surgery procedures are modifiable risk factors that are associated with increased cardiovascular events and 30-day mortality. The aim of this study is to evaluate the effect of transfusion timing (intraoperative vs. postoperative) on the rate of postoperative myocardial infarction (POMI) and death. ⋯ In our series with routine postoperative troponin screening in the inpatient setting, the use of an isolated postoperative transfusion as well as cases requiring both an intraoperative and postoperative transfusion was associated with POMI. However, isolated intraoperative transfusion was not associated with POMI, and we did not identify an association of transfusion with 30-day mortality. These data suggest that the perioperative setting of transfusions is important in its impact on postoperative outcomes and needs to be accounted for when evaluating transfusion outcomes and indications.

Left subclavian artery revascularization during endovascular repair of aortic dissection is often accomplished by left carotid-subclavian artery bypass or transposition. In situ fenestration of thoracic stent grafts provides an alternative method of revascularization without manipulation of the left carotid artery. We describe a case whereby in situ laser fenestration, combined with catheter-directed thrombectomy, was utilized to revascularize a thrombosed left subclavian artery following a frozen elephant trunk repair of type A aortic dissection. ⋯ Postoperative CT scan showed patent left subclavian branch stent and no endoleak across the fenestration of the aortic stent graft. Delayed laser in situ fenestration of a PTFE stent graft can be performed safely. The vertebral artery protection and catheter-directed thrombectomy are important adjuncts to reduce the risk of posterior stroke.
