Lower extremity arterial injury may result in limb loss after blunt or penetrating trauma. This study examined outcomes of civilian lower extremity arterial trauma and predictors of delayed amputation. ⋯ Individualized decision making based on age, mechanism, pulseless presentation, extent of musculoskeletal trauma, and location of injury should guide the intensity of revascularization strategies after extremity arterial trauma. Although patients presenting with vascular trauma in the setting of multiple negative prognostic factors should not be denied revascularization, expectations for limb salvage in the short-term and long-term periods should be carefully outlined.

A variety of patient factors are known to adversely impact outcomes after carotid endarterectomy (CEA) or carotid artery stenting (CAS). However, their specific impact on complications and mortality and how they differ between CEA and CAS is unknown. The purpose of this study is to identify patient and hospital factors that adversely impact outcomes. ⋯ Higher rates of postoperative stroke and inpatient mortality for women undergoing CAS is an unexpected finding, and may indicate that this population is vulnerable to complications after endovascular management. Low volume is a predictor of complications and subsequent mortality primarily for CAS. Patients who undergo CEA continue to have superior outcomes compared with matched cohorts who undergo CAS.

Branched versus fenestrated endografts for endovascular repair of aortic arch lesions.
Endovascular repair of the aortic arch represents a formidable challenge because of aortic diameter, angulation, elasticity, and greater distance to the femoral access vessels. Whereas both fenestrated and branched endografts have been customized to accommodate complex pathologic processes of the arch, no data comparing the techniques are available. The aim of this study was to compare the outcomes of custom-made fenestrated vs branched thoracic endovascular aortic repair (fTEVAR vs bTEVAR). ⋯ Both fTEVAR and bTEVAR are feasible for the treatment of aortic arch diseases in high-risk patients. Results are promising, although fTEVAR was associated with higher mortality in this early experience. bTEVAR was more commonly used in Ishimaru zone 0.

The cost of treating diabetes-related disease in New Zealand is increasing and is expected to reach New Zealand dollars (NZD) 1.8 billion in 2021. The financial burden attached to the treatment of diabetic foot wounds is difficult to quantify and reported costs of treatment vary greatly in the literature. As of yet, no study has captured the true total cost of treating a diabetic foot wound. In this study, we investigate the total minimum cost of treating a diabetic foot ulcer at a tertiary institution. ⋯ We estimate the minimum median cost incurred by our department of vascular surgery in treating a diabetic foot wound to be NZD 30,000 and identify wound treatment modality to be a significant determinant of cost. While readily acknowledging our study's inherent limitations, we believe it provides a real-world representation of the minimum total cost involved in treating diabetic foot lesions in a tertiary center. Given the increasing rate of diabetes, we believe this high cost reinforces the need for the establishment of a multidisciplinary diabetic foot team in our region.

Comparative Study
Outcomes for symptomatic abdominal aortic aneurysms in the American College of Surgeons National Surgical Quality Improvement Program.
Historically, symptomatic abdominal aortic aneurysms (AAAs) were found to have intermediate mortality compared with asymptomatic and ruptured AAAs; but with wider use of endovascular aneurysm repair (EVAR), a more recent study suggested that mortality of symptomatic aneurysms was similar to that of asymptomatic AAAs. These prior studies were limited by small numbers. The purpose of this study was to evaluate the mortality and morbidity associated with symptomatic AAA repair in a large contemporary population. ⋯ Patients with symptomatic AAAs had a twofold increased risk of perioperative mortality compared with patients with asymptomatic aneurysms undergoing repair. Furthermore, patients with ruptured aneurysms have a sevenfold increased risk of mortality compared with patients with symptomatic aneurysms.
