This study prospectively assessed the diagnostic accuracy of a novel bilateral photoplethysmography toe pulse measurement technique for the detection of significant lower limb peripheral arterial disease. ⋯ This simple-to-use technique could offer significant benefits for the diagnosis of peripheral arterial disease in settings such as primary care where noninvasive, accurate, and diagnostic techniques not requiring specialist training are desirable. Improved diagnosis and screening for peripheral arterial disease has the potential to allow identification and risk factor management for this high-risk group.

Lower extremity arterial injury is a rare complication following total knee (TKA) or total hip arthroplasty (THA). To date, no multi-institutional study has identified preoperative factors that may portend increased risk for these injuries. We queried a large clinical database for the incidence and predictors of arterial injury and/or compromise following lower extremity arthroplasty. ⋯ Lower extremity arterial injury was exceedingly rare after total knee or total hip arthroplasty. There is an increased incidence in African American patients and those undergoing redo arthroplasty. Among patients who sustain vascular injury, excellent limb salvage rates can be achieved with close postoperative surveillance to achieve early detection and repair of injuries.

We hypothesized that a subgroup of patients with frank stroke due to sudden occlusion of the internal carotid artery could safely undergo surgery to restore carotid patency and to rescue brain tissue not yet irreversibly damaged if current stroke diagnostic methods were applied. ⋯ Restoration of blood flow in an acutely occluded internal carotid artery can only be achieved in the acute stage. Our pilot study demonstrated that a thorough diagnostic workup allows selection of patients who may benefit from urgent revascularization of acute internal carotid artery occlusion in the stage of an acute stroke. A prospective randomized multicenter trial comparing surgery with conservative medical treatment is needed.

Comparative Study
Open repair of juxtarenal aortic aneurysms (JAA) remains a safe option in the era of fenestrated endografts.
Widespread application of infrarenal endovascular aneurysm repair (EVAR) has resulted in a proportionate increase in open juxtarenal aortic aneurysm (JAA) repairs. Fenestrated endograft technology for JAA is developing rapidly, but only limited outcomes are known. The aim of this study was to review our open JAA experience in an era of fenestrated endograft technology, identify factors associated with increased surgical risk, determine early and midterm outcome, and provide a basis for comparison for future endovascular procedures. ⋯ Open surgical repair of JAA is associated with low mortality and remains the gold standard. Although 18% had renal complications, only one patient had permanent renal failure. Patients with a combination of physiologic and anatomic risk factors identified on multivariate analysis may benefit from fenestrated endograft repair.

The aim of this study was to evaluate the short- and midterm results following endovascular repair of a traumatic rupture of the aortic isthmus. ⋯ Short and midterm results following endovascular treatment for traumatic rupture of the aortic isthmus favor the proposition of endovascular repair as the first-line treatment in hemodynamically unstable patients. In hemodynamically stable patients, the preoperative morphological evaluations aim to assess aortic anatomy and thereby detect possible technical limitations (aortic diameter <20 mm, severe aortic isthmus angulation, short proximal aortic neck <20 mm, conical aorta). In the presence of any one of these technical restrictions, open surgical treatment should be discussed to avoid major per- or postoperative complications related to endovascular repair. Further studies and long-term survival studies are mandatory to determine the efficacy and durability of this technique.
