Objective: BEST-CLI, an international randomised trial, compared an initial strategy of bypass surgery with endovascular treatment in chronic limb threatening ischaemia (CLTI). In this substudy, overall amputation rates and risk of major amputation as an initial or subsequent outcome were evaluated.
Methods: A total of 1 830 patients were randomised to receive surgical or endovascular treatment in two parallel cohorts: patients with adequate single segment great saphenous vein (SSGSV) (n = 1 434) were assigned to cohort 1; and patients without adequate SSGSV (n = 396) were assigned to cohort 2.
Background: The most challenging lower extremity traumatic injuries involve concomitant vascular and orthopedic injuries with amputation rates approaching 50%. Controversy exists as to how to prioritize the vascular and orthopedic repairs. We reviewed patients with popliteal artery and lower extremity orthopedic injuries to analyze the sequence of the vascular and orthopedic repairs on outcomes.

We investigated whether TXA increases the risk of thrombosis-related technical failure (TRTF) in major vascular injuries (MVI).
Methods: The PROspective Observational Vascular Injury Treatment (PROOVIT) registry was queried from 2013 to 2022 for MVI repaired with an open or endovascular intervention.
Background The best medical therapy to control hypertension following abdominal aortic aneurysm repair is yet to be determined. We therefore examined whether treatment with renin-angiotensin-aldosterone system inhibitors (RAASIs) versus beta blockers influenced postoperative and 1-year clinical end points following abdominal aortic aneurysm repair in a Medicare-linked database. Methods and Results All patients with hypertension undergoing endovascular aneurysm repair and open aneurysm repair in the Vascular Quality Initiative Vascular Implant Surveillance and Interventional Outcomes Network database between 2003 and 2018 were included.

Nonetheless, data regarding the impact of lesion length on outcomes of transcarotid artery revascularization (TCAR) with flow reversal are lacking. Herein, we aimed to compare the outcomes of TCAR vs TFCAS stratified by the length of the carotid lesion.

Methods: From January 2015 to January 2020, a HIPAA (Health Insurance and Accountability Act)-compliant, institutional review board-approved, retrospective clinical study analyzed contrast-enhanced abdominopelvic CTA scans from 200 patients with infrarenal AAAs and 200 propensity-matched control patients with non-aneurysmal infrarenal abdominal aortas. A CNN was trained to binary classification on the input.
Background: Renal artery stenosis (RAS) is an uncommon cause of pediatric hypertension. Guidelines for workup and management have not been established. The most widely reported etiology of the pediatric renovascular disease has been fibromuscular dysplasia; however, other etiologies including middle aortic syndrome (MAS) and vasculitides have been described.

Our goal was to analyze the use of a previously reported conservative wound care approach to non-infected (foot infection score of zero), diabetic foot ulcers with mild-moderate peripheral arterial disease enrolled in a conservative tier of a multidisciplinary limb preservation program.
Methods: Veterans with CLTI and tissue loss were prospectively enrolled into our Prevention of Amputation in Veterans Everywhere (PAVE) program.
Background: In traumatic axillo-subclavian vessel injuries, endovascular repair has been increasingly described, despite ongoing questions regarding infection risk and long-term durability. We sought to compare the clinical and safety outcomes between endovascular and surgical treatment of traumatic axillo-subclavian vessel injuries.
Method: A search query of the prospectively maintained PROOVIT registry for patients older than 18 years of age with a diagnosis of axillary or subclavian vessel injury between 2014-2019 was performed at a Level 1 Trauma Center.
Objective: Our institution's multidisciplinary Prevention of Amputation in Veterans Everywhere (PAVE) program allocates veterans with critical limb threatening ischemia (CLTI) to immediate revascularization, conservative care, primary amputation, or palliative limb care according to previously reported criteria. These four groups align with the approaches outlined by the global guidelines for the management of CLTI. In the present study, we have delineated the natural history of the palliative limb care group of patients and quantified the procedural risks and outcomes.

However, data on outcomes of concomitant revascularization procedures are lacking. We studied the outcomes of patients with CLTI who underwent suprainguinal bypass (SIB) alone, SIB with concomitant infrainguinal bypass (IIB), and SIB with concomitant infrainguinal peripheral endovascular intervention (IIPVI).
View Article and Find Full Text PDFObjective: Endovascular abdominal aortic repair can involve the incorporation of renal arteries. Revascularization after intentional or unintentional renal artery (RA) coverage is not always technically successful, and the loss of a single RA may result in the need for postoperative dialysis. Thus, we compared the outcomes after endovascular aneurysm repair (EVAR) stratified by RA involvement (RAI).

A systems-based analysis evaluating intraoperative radiation can help identify high use factors and dose reduction behaviors leading to quality improvement initiatives.
Methods: A retrospective review of all operative fluoroscopic-guided procedures from 2010 to 2017 from 4 hospitals in a tertiary academic health care system was performed.
Patient frailty indices are increasingly being utilized to anticipate post-operative complications. This study explores whether a 5-factor modified frailty index (mFI-5) is associated with outcomes following below-knee amputation (BKA). All BKAs in the vascular quality initiative (VQI) amputation registry from 2012-2017 were reviewed.

Our primary goal was to evaluate wound healing, limb salvage, and survival among patients with ischemic wounds undergoing revascularization when intervention was deferred by a trial of conservative wound therapy.
Methods: All patients with peripheral arterial disease and tissue loss are prospectively enrolled into our Prevention of Amputation in Veterans Everywhere limb preservation program.
Background: Endovascular treatment of Trans-Atlantic Inter-Society Consensus (TASC) II D aortoiliac lesions is now an accepted form of revascularization. We sought to demonstrate that native microchannel recanalization and orbital atherectomy is a successful recanalization method of TASC II D aortoiliac lesions refractory to standard recanalization techniques.
Methods: Four consecutive patients from 2016 to 2018 with symptomatic TASC II D aortoiliac occlusive disease prohibitive for open bypass and failed traditional prodding guidewire or device recanalization technique were identified and underwent advanced native microchannel selection and subsequent orbital atherectomy (Cardiovascular Systems, Inc, St Paul, MN).
Objective: The Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) classification system has been validated to predict wound healing and limb salvage of patients with peripheral artery disease (PAD). Our goal was to evaluate the association between WIfI stage and wound healing, limb salvage, and survival in a select cohort of patients with PAD and tissue loss undergoing an attempt of wound healing without immediate revascularization (conservative approach) in a multidisciplinary wound program.
Methods: Veterans with PAD and tissue loss were prospectively enrolled in our Prevention of Amputation in Veterans Everywhere (PAVE) program.
Background: There is no currently accepted standard in safety evaluation for radial artery intervention. We sought to compare the accuracy of various subjective and objective screening techniques in predicting safety for radial artery intervention.
Methods: Fifty-four patients in a prospective cohort study at a single institution underwent subjective Allen's test, objective Barbeau test, and several objective hand ultrasound techniques to assess safety for radial artery intervention.
