Comparative Study
Influence of anesthesia type on outcome after endovascular aortic aneurysm repair: an analysis based on EUROSTAR data.
Local and regional anesthesia was used in endovascular aortic aneurysm repair (EVAR) shortly after its introduction, and the feasibility has been documented several times. Nevertheless, locoregional anesthesia has not become accepted on a large scale, probably owing to a traditional surgical attitude preferring general anesthesia. This study compared various anesthesia techniques in patients treated with EVAR for infrarenal aortic aneurysms. ⋯ The EUROSTAR data indicate that patients appeared to benefit when a locoregional anesthetic technique was used for EVAR. Locoregional techniques should be used more often to enhance the perioperative advantage of EVAR in treating infrarenal aneurysms of the abdominal aorta.

The natural history of limbs affected by ischemic ulceration is poorly understood. In this report, we describe the outcome of limbs with stable chronic leg ulcers and arterial insufficiency that were treated with wound-healing techniques in patients who were not candidates for revascularization. ⋯ Limb salvage can be achieved in most patients with arterial insufficiency and uncomplicated chronic nonhealing limb ulcers using a program of wound management without revascularization. Healing proceeds slowly, however, requiring more than a year in many cases. Patients with an ABI <0.5 are more likely to require amputation. Interventions designed to improve outcomes in critical limb ischemia should stratify outcomes based on hemodynamic data and should include a comparative control group given the natural history of ischemic ulcers treated in a dedicated wound program.

In our transition from elective abdominal aortic aneurysm (AAA) to emergent ruptured AAA (r-AAA) repair with endovascular techniques, we recognized that the availability of endovascularly trained staff in the operating rooms and emergency departments, and adequate equipment were the limiting factors. To this end, we established a multidisciplinary protocol that facilitates endovascular repair (EVAR) of r-AAA. ⋯ The early results show that emergent endovascular treatment of hemodynamically stable and unstable patients is associated with a limited mortality of 18% once a standardized protocol is established. There is an increased recognition of emerging complications with an endovascular approach, and a synchrony of disciplines must be developed to initiate a successful program for endovascular treatment of r-AAAs.

Popliteal arterial trauma carries the greatest risk of limb loss of any peripheral vascular injury. The purpose of this study was to analyze outcomes after popliteal arterial injuries and identify factors contributing to disability. ⋯ Popliteal vascular injury remains an uncommon but challenging clinical entity associated with significant rates of limb loss, functional disability, and mortality. Blunt vs penetrating mechanism and associated musculoskeletal injuries generally involve longer hospital stays, worse functional outcomes, and twice the amputation rate.
