We describe a case of Kommerell's diverticulum involving the distal portion of a right-sided aortic arch and the origin of an aberrant left subclavian artery (LSA). The patient underwent a total endovascular repair with the use of a modified Valiant endograft (Medtronic, Minneapolis, Minn) to which a branch was attached to keep LSA patency. Postoperative computed tomography showed complete exclusion of the lesion, without endoleaks. The use of "customized off-label" devices to treat special conditions was feasible in this case, keeping patency of the LSA without risk of arm claudication or the requirement for a complementary surgical bypass.

In acute traumatic bleeding, permissive arterial hypotension with delayed volume resuscitation is an established lifesaving concept as abridge to surgical control. This study investigated whether preoperatively administered volume also correlated inversely with survival after ruptured abdominal aortic aneurysm (rAAA). ⋯ Aggressive volume resuscitation of patients with rAAAs before proximal aortic control predicted an increased perioperative risk of death, which was independent of systolic blood pressure. Therefore, volume resuscitation should be delayed until surgical control of bleeding is achieved.

Multicenter Study Clinical Trial
Results of a multicenter, prospective trial of thoracic endovascular aortic repair for blunt thoracic aortic injury (RESCUE trial).
To evaluate the early outcomes of patients undergoing thoracic endovascular aortic repair for blunt thoracic aortic injuries. ⋯ Based on the early outcomes, the Medtronic Valiant Captivia stent graft appears to be a promising treatment modality for blunt thoracic aortic injuries. Long-term follow-up is necessary to substantiate the effectiveness of thoracic endovascular aortic repair in treatment of blunt thoracic aortic injuries.

Single-segment saphenous vein remains the optimal conduit for infrainguinal revascularization. In its absence, prosthetic conduit may be used. Existing data regarding the significance of anastomotic distal vein adjunct (DVA) usage with prosthetic grafts are based on small series. ⋯ This contemporary multi-institutional propensity-matched study demonstrates that patients that receive distal anastomotic vein adjuncts as part of infrainguinal prosthetic bypass operations in general have more extreme comorbidities and more technically challenging operations based on level of target vessel and prior bypass attempts. After propensity-matched analysis, the use of a DVA may protect against MALEs in prosthetic bypass surgery and should be considered when feasible.

Thirty-day unplanned readmission after lower extremity bypass represents a large cost burden and is a logical target for cost-containment strategies. We undertook this study to evaluate factors associated with unplanned readmission after lower extremity bypass. ⋯ Thirty-day unplanned readmission is a frequent occurrence after lower extremity bypass (23.0%). Stratifying patients by risk factors associated with unplanned readmission is essential for quality improvement and equitable resource allocation when disease-specific bundling strategies are being derived.
