Background: Endovascular management of complex aortoiliac occlusive disease (AIOD) has been described as a viable alternative to open surgical reconstruction. To date, few studies have directly compared the 2 techniques. We therefore, evaluated short and mid- term outcomes of open and endovascular therapy in TASC II D AIOD patients.

We sought to determine the effect of LE ischemic time on neurologic impairment after FEVAR.
Methods: Consecutive patients who underwent FEVAR at a single institution were analyzed.
Objective: Recent studies have demonstrated an increase in trauma mortality relative to mortality from cancer and heart diseases in the United States. Major vascular injuries such as to the inferior vena cava (IVC) and aortic injuries remain responsible for a significant proportion of early trauma deaths in modern trauma care. The purpose of this study was to explore patterns in epidemiology and mortality after IVC and aortic injuries in the United States.

We present our experience with filter-induced inferior vena cava occlusion in order to assess the feasibility, safety, and effectiveness of endovascular management. Methods A retrospective review of all patients undergoing inferior vena cava filter placement over a 60-month study period was performed.

We present data to describe current use of endovascular surgery in vascular trauma.
Methods: Registry data from March 2013 to December 2016 were reviewed.
Objective: In the absence of suitable autologous vein, the use of prosthetic grafts for infragenicular bypasses in peripheral arterial disease has become standard practice. The purpose of this study was to investigate whether creating a vein patch at the distal anastomosis would further improve patency and freedom from major adverse limb events (MALEs). Furthermore, we sought to investigate whether the use of a distal vein patch (DVP) was associated with lower rates of acute limb ischemia (ALI) for those presenting with occluded prosthetic bypass graft.

However, little is known about the epidemiology and outcomes of endovascularly managed arterial injuries in children. We therefore aimed to evaluate recent trends in the endovascular management of pediatric arterial injuries and its association with early survival.

Methods: A retrospective study was performed of patients who sustained axillosubclavian arterial injuries admitted to two high-volume academic trauma centers between 2003 and 2013.
Background: Multidetector computed tomographic angiography (MDCTA) has become the gold standard for the early assessment of lower extremity vascular injury. The objective of this study was to evaluate the predictive value of MDCTA documented vessel run-off to the foot on limb salvage rates after lower extremity vascular injury.
Methods: All trauma patients undergoing lower extremity MDCTA for suspected vascular injury assessed at 2 high-volume Level I trauma centers between January 2009 and December 2012.
Background: Over 1 million healthcare providers have participated in the Advanced Trauma Life Support course. No studies have evaluated factors that predict course performance. This study aims to identify these predictors.

Methods: Eight consecutive patients (6 men; mean age 57.4 years, range 34-78 years) with acute thrombotic occlusion of the IVC in the presence of an IVC filter underwent percutaneous venous thrombectomy using the Trellis-8 thrombectomy system and adjunctive techniques between January 2009 and November 2013.
Background: Do-not-resuscitate (DNR) orders allow patients to communicate their wishes regarding cardiopulmonary resuscitation. Although DNR status may influence physician decision making regarding resuscitation, the effect of DNR status on outcomes of patients undergoing emergency vascular operation remains unknown. The aim of this study was to analyze the effect of DNR status on the outcomes of emergency vascular surgery.

Methods: A total of 201 consecutive patients with threatened limbs treated from 2010 to 2011 in an academic medical center were analyzed. These patients were stratified into clinical stages 1 to 4 on the basis of the SVS WIfI classification.
Background: Thoracic aortic emergencies account for 10% of thoracic-related admissions in the United States and remain associated with high morbidity and mortality rates. Open repair has declined owing to the emergence of thoracic endovascular aortic repair (TEVAR), but data on emergency TEVAR use for acute aortic pathology remain limited. We therefore reviewed our experience.

The objective of this article was to characterize the association between external wounds and the corresponding internal injuries after penetrating neck trauma to identify the clinical use of the anatomic zones of the neck.

The objective of this study was to examine the impact of lyophilized human and porcine platelets in a swine liver injury model of nonsurgical hemorrhage.
Methods: Anesthetized pigs (40 kg) had a controlled 35% total blood volume bleed from the right jugular vein followed by cooling to 35°C and resuscitation with Ringer's lactate to achieve a 3:1 blood withdrawal resuscitation.
Objective: The rapid evolution of endovascular surgery has greatly expanded management options for a wide variety of vascular diseases. Endovascular therapy provides a less invasive alternative to open surgery for critically ill patients who have sustained arterial injuries. The purpose of this study was to evaluate recent trends in the management of arterial injuries in the United States with specific reference to the use of endovascular strategies and to examine the outcomes of endovascular vs open therapy for the treatment of civilian arterial traumatic injuries.
