Predicting 1-year mortality after elective abdominal aortic aneurysm repair.
Benefit of prophylactic abdominal aortic aneurysm (AAA) repair requires sufficient survival to overcome operative risk. Since death within 1 year of elective open or endovascular (EVAR) infrarenal AAA repair likely indicates ineffective treatment, we developed a prediction model for 1-year mortality to aid clinical decision-making. ⋯ Predictors of 1-year mortality can identify patients less likely to benefit from elective AAA repair. These factors differ for open repair vs EVAR and should be considered in individual patient decision-making. Our EVAR model had less impact on 1-year survival, even if CHF and large AAA diameter were present. However, a combination of age, COPD, renal insufficiency, and need for suprarenal clamping have significant impact on 1-year mortality after open AAA repair. Consideration of these variables should assist decision-making for elective AAA repair, especially in borderline cases.

Cerebral hyperperfusion syndrome is a rare, serious complication of carotid revascularization either after carotid endarterectomy or carotid stent placement. Impaired cerebral autoregulation and post-revascularization changes in cerebral hemodynamics are the main mechanisms involved in the development of the syndrome. ⋯ This article reviews the literature, intending to make a synthesis of all new data concerning the clinical manifestations of hyperperfusion syndrome, the pathophysiologic pathways involved in its development, the prediction, and the appropriate management. Also, a review of the most recent series of hyperperfusion syndrome following carotid revascularization, both with classic open endarterectomy and carotid artery stenting has been performed.

Blunt thoracic aortic injury (BAI) remains a leading cause of trauma deaths, and off-label use of endovascular devices has been increasingly utilized in an effort to reduce the morbidity and mortality in this population. Utilizing a nationwide database, we determined the incidence of BAI, and analyzed both functional and survival outcomes at discharge compared with matched controls. ⋯ This manuscript is the first to define the incidence of BAI utilizing the NTDB. Remarkably, two-thirds of patients are unable to undergo attempts at aortic repair, which portends a poor prognosis. When controlling for associated injuries, blunt aortic injury independently impacts survival and results in poor function in those surviving to discharge.

Ultrasound-guided foam sclerotherapy is a generally safe, cost-effective, and practical technique for the treatment of certain venous malformations; however, not all vascular malformation lesions are amenable to the ultrasound-guided method. Venous outflow of the sclerosing agent and extravasation are difficult to check when only ultrasound guidance is used. This study describes a new fluoroscopy-guided technique that uses standardized sclerosing foam for peripheral venous malformations. The short-term efficacy and safety of fluoroscopy-guided foam sclerotherapy for peripheral venous malformations was evaluated. ⋯ Fluoroscopic guidance could have great promise in foam sclerotherapy of peripheral venous malformations, although larger studies are necessary to determine the advantages of this technique over other sclerotherapeutic methods.

This study tested the hypothesis that silent embolic infarcts on computed tomography (CT) brain scans can predict ipsilateral neurologic hemispheric events and stroke in patients with asymptomatic internal carotid artery stenosis. ⋯ The presence of silent embolic infarcts can identify a high-risk group for ipsilateral hemispheric neurologic events and stroke and may prove useful in the management of patients with moderate asymptomatic carotid stenosis.
