..The best method of recruitment for screening of those most at risk for AAA in the United States remains to be determined...

..Longer-term survival rates, however, were similar for the two procedures. There are currently no long-term, population-based data from the comparison of these strategies...

..To examine the modern epidemiology of abdominal aortic aneurysm (AAA) rupture and short-term AAA-related mortality after the introduction of endovascular aneurysm repair (EVAR)...

..However, long-term survival is similar after endovascular and open surgical repair. Those at risk of AAA who would benefit from repair should undergo screening...

..In the absence of data from these trials, the threshold for intervention should not be changed...

..Often, 30-day mortality is reported because in-hospital mortality may be biased in favor of endovascular repair given the shorter length of stay. However, the duration of increased risk of death after aneurysm repair is unknown...

..The associated costs are poorly defined in the literature. We sought to determine national estimates for the costs, utilization, and outcomes of angioplasty and bypass graft for the treatment of both claudication and limb threat...

..It is unclear if there has been nationwide adoption of this methodology or whether there is actually a mortality benefit...

..However, long-term results comparing these modalities for primary intervention in patients who have had no prior intervention have not been reported. We report our results with 3-year follow-up...

..We investigated the experience of a single institution over 10 years with bypass grafts involving the femoral artery to determine the incidence and risk factors for prosthetic graft infection...

..We examined lower extremity bypasses by graft origin and body mass index (BMI) classification to analyze differences in postoperative mortality and SSI occurrence...

..In order to investigate this, we developed a differential predictive model of perioperative mortality after AAA repair...

..To evaluate national outcomes after endovascular and open surgical repair of ruptured abdominal aortic aneurysms (rAAA)...

..We hypothesized that the use of ultrasound scan guidance allowed us to safely increase the utilization of percutaneous endovascular aortic aneurysm repair to almost all patients and decrease access complications...

..The aim of this study is to identify patient and graft characteristics predictive of failure after PTA of infrainguinal vein grafts...

..We evaluated national outcomes after open repair of abdominal aortic aneurysms (AAAs) with visceral or renal bypass (VRB)...

..Later open surgery can be performed for restenosis if nutritional status and surgical risk are improved, or repeat angioplasty and stenting can be effectively performed if operative risk remains high...

..Concomitant common femoral endarterectomy or better assessment of femoral disease may improve durability...

..If DU enables adequate identification of a target artery for bypass grafting, and especially if the peroneal artery is seen, findings at CA are not likely to alter bypass execution...

..In this study, we evaluated the predictive ability of increased preoperative PP to identify MACEs in patients with peripheral vascular disease undergoing lower extremity vascular bypass surgery...

..The effect of reinterventions on survival, however, is unknown. We therefore evaluated the rate of reinterventions and readmission after initial AAA repair, 30-day mortality, and the effect on long-term survival...

..To compare endovascular (EVAR) and open surgical repair (OSR) for ruptured abdominal aortic aneurysms (RAAA) in terms of preoperative hemodynamic status and comorbidities...

..We report our experience with infrapopliteal angioplasty stratified by TASC lesion classification...

..To evaluate this, we looked at national trends in AAA repair volume as well as mortality rates after intact and ruptured AAA repair encompassing the introduction of EVAR...

..Furthermore, this study evaluates the effect of endovascular procedure volume on the frequency of subtypes of open lower extremity procedures performed...

..We studied the role of obesity in outcomes in lower extremity arterial revascularization...

..Although CMS requires data submission only on CAS, the VR collects similar data on carotid endarterectomy (CEA) to allow comparison of outcomes, as well as potential for expansion to other procedures...

..There is a well-established literature relating procedure volume to outcomes, but incorporating such information into clinical decision making is problematic when there is >1 treatment option for a condition...

..Little is known about the relative impact of body mass index (BMI) on these outcomes after open (OAR) and endovascular abdominal aortic aneurysm repair (EVAR)...

..This may bias comparisons of CAS and carotid endarterectomy (CEA). We evaluate mortality and stroke following CAS and CEA stratified by medical high risk criteria...

..When 2 treatment approaches are available, there are likely to be unmeasured confounders that influence choice of procedure, which complicates estimation of the causal effect of treatment on outcomes using observational data...

..Fusion of the spine is often performed from an anterior approach requiring mobilization of aorta, iliac artery, and vein. This study describes the preferred techniques and incidence of vascular complications at a spine center...

..To evaluate national outcomes after open repair of descending thoracic aortic aneurysm (DTA)...

..We set forth to investigate whether endovascular treatment in this setting would result in an acceptable limb salvage rate...

..This approach also allows a better interface between the stent and endarterectomy than staged preoperative stenting. Technical success and early patency rates are excellent...

..The goal of the present study was to evaluate whether ejection fraction (EF) is predictive of outcome in infrainguinal arterial reconstruction...

..Given the increasing use of therapeutic hypothermia used during the placement these devices and in post-cardiac arrest situations, we sought to understand the impact of hypothermia on this device...

..No similar report was found describing this entity treated with this approach...

..Most patients were selected for CAS if they had indications for endarterectomy (CEA) but were considered at high risk for surgery...

..We sought to determine national estimates for the use and mortality of thoracic endovascular aortic repair (TEVAR) for T(B)AD in the United States...

..The use of saphenous vein as a conduit results in the best patency for plantar or lateral tarsal bypass procedures...

..We analyzed modes of presentation, methods of operative repair, and follow-up in all consecutive patients with chronic ischemia of the upper extremity requiring arterial bypass...

..We used decision analysis to examine the effect of these competing risks on quality-adjusted life expectancy (QALE) after ENDO and OPEN...

..05). Other ongoing trials will address not only whether CAS could be superior to CEA in high-risk patients but also, more importantly, whether CAS is beneficial in other subgroups, such as low-risk and asymptomatic patients...

..The stent graft was then placed with embolization protection. The repair was performed without complication, and the aneurysm remained successfully excluded at 6-month follow-up...

..CT with 3-D CAMPS can effectively eliminate the need for preoperative arteriography and avert associated morbidity, expense, and exposure to contrast agent and radiation...

..There is conflicting evidence regarding restenosis with gold-coated stents. To evaluate the effect of gold coating on restenosis after renal stenting, we reviewed the results of all patients undergoing RAS in our practice...

..We evaluated the outcomes and complications of RAS performed by vascular surgeons at our institution with modern low-profile systems...
