Impact of preoperative risk factors on 5-year survival after fenestrated/branched endovascular aortic repair.

Objective: To investigate which preoperative factors most impact the 5-year survival of patients undergoing fenestrated/branched endovascular aortic repair (F/BEVAR) and to identify modifiable elements that, if time allows, should be actively managed and adequately controlled preoperatively.

Methods: Patients treated for aortic aneurysms with complex anatomy using either patient-specific company-manufactured or off-the-shelf F/BEVAR devices were included. The exposure of interest was aneurysm type (group I: type I-III thoracoabdominal aneurysms vs group II: type IV thoracoabdominal aneurysms vs group III: juxtarenal or suprarenal aneurysms), and the primary outcome was 5-year risk of all-cause mortality.

Ultrasound-Mediated Antibiotic Delivery to In Vivo Biofilm Infections: A Review.

Bacterial biofilms are a significant concern in various medical contexts due to their resilience to our immune system as well as antibiotic therapy. Biofilms often require surgical removal and frequently lead to recurrent or chronic infections. Therefore, there is an urgent need for improved strategies to treat biofilm infections.

Five-year outcomes of fenestrated and branched endovascular repair of complex aortic aneurysms based on aneurysm extent.

Objective: The aim of this study was to evaluate the 5-year outcomes of fenestrated/branched endovascular aortic repair (F/BEVAR) for the treatment of complex aortic aneurysms stratified by the aneurysm extent.

Methods: Patients with the diagnosis of complex aortic aneurysm, who underwent F/BEVAR at a single center were included in this study and retrospectively analyzed. The cohort was divided according to the aneurysm extent, comparing group 1 (types I-III thoracoabdominal aneurysms [TAAAs]), group 2 (type IV TAAAs), and group 3 (juxtarenal [JRAAs], pararenal [PRAAs], or paravisceral [PVAAs] aortic aneurysms).

Improvement of Chronic Venous Insufficiency Related Leg Xerosis and Dermatitis With Ceramide-Containing Cleansers and Moisturizers: An Expert-Based Consensus.

Introduction: Chronic venous insufficiency (CVI) may lead to sustained elevated pressure (aka venous hypertension) in the dermal venous microcirculation. Risk factors include advanced age, obesity, female gender, pregnancy, and prolonged standing. CVI in the lower extremities may lead to cutaneous changes such as xerosis and venous leg dermatitis (VLD).

Differential impact of missed initial wound clinic visit on 6-month wound healing by race/ethnicity among patients with chronic limb-threatening ischemia.

Chronic limb-threatening ischemia (CLTI) is associated with significant morbidity, including major limb amputation, and mortality. Healing ischemic wounds is necessary to optimise vascular outcomes and can be facilitated by dedicated appointments at a wound clinic. This study aimed to estimate the association between successful wound care initiation and 6-month wound healing, with specific attention to differences by race/ethnicity.

Gender disparities in patients with aortoiliac disease requiring open operative intervention.

Background: Numerous endovascular options have been used for the repair of juxtarenal aortic aneurysms (JRAAs) over the last 15 years. This study aims to compare the performance between the Zenith p-branch device and custom-manufactured fenestrated-branched devices (CMD) for the treatment of asymptomatic JRAA.

Methods: A single-center retrospective analysis of prospectively collected data was performed.

Iliac vein recanalisation and stenting accelerate healing of venous leg ulcers associated with severe venous outflow obstruction.

Obstruction involving the iliac veins and/or inferior vena cava is highly comorbid in patients with chronic venous leg ulcers and is a barrier to healing. Intervention with venous stenting is recommended to promote wound healing; however, there is limited data to quantify the effects of venous outflow restoration on wound healing. We retrospectively identified patients with venous ulcers and comorbid venous outflow obstruction.

Purpose: To establish the updated position of the Society of Interventional Radiology (SIR) on the endovascular management of acute iliofemoral deep vein thrombosis (DVT).

Materials And Methods: A multidisciplinary writing group with expertise in treating venous diseases was convened by SIR. A comprehensive literature search was conducted to identify studies on the topic of interest.

Livedoid vasculopathy: A review with focus on terminology and pathogenesis.

Livedoid vasculopathy (LV) is a rare thrombotic vasculopathy of the dermis characterized by painful, relapsing ulcers over the lower extremities. Diagnosis is challenging due to the overlap in clinical appearance and nomenclature with other skin disorders. Treatment selection is complicated by poor understanding of the pathogenesis of LV and lack of robust clinical trials evaluating therapy efficacy.

Routine use of concurrent fluoroscopic imaging during superficial endovenous interventions: A position statement of the International Union of Phlebology, the Australasian College of Phlebology, the Australia and New Zealand Society for Vascular Surgery, the American Venous Forum, the American Vein and Lymphatic Society, the European College of Phlebology and the Interventional Radiology Society of Australasia.

International evidence-based guidelines recommend preoperative duplex ultrasound mapping in the assessment of chronic venous disease, and concurrent ultrasound imaging to guide superficial endovenous interventions such as endovenous laser ablation, radiofrequency ablation, cyanoacrylate adhesive closure, and sclerotherapy (ultrasound-guided sclerotherapy). Other imaging modalities such as venography, alone or in combination with computed tomography scan or magnetic resonance imaging, may be included in the preoperative assessment of a small and select group of patients to exclude central venous obstruction, certain deep venous pathologies, pelvic origin extrapelvic varices, and complex vascular malformations. The signatory scientific and medical societies recommend against the routine use of fluoroscopy and other radiation-based imaging in the investigation and treatment of superficial venous disease.

Incidence of venous thromboembolism in patients with peripheral arterial disease after endovascular intervention.

Objective: Venous thromboembolism (VTE) is a well-known postoperative complication; however, the incidence of VTE after peripheral vascular intervention (PVI) has not been well described. Despite the minimally invasive nature of these procedures, the patients undergoing PVI have significant risk factors for the development of VTE. In the present study, our objective was to describe the short-term incidence of VTE after PVI, identify differences between sexes, and examine the periprocedural antiplatelet and anticoagulation regimens.

Midterm and Long-Term Outcomes following Dedicated Endovenous Nitinol Stent Placement for Symptomatic Iliofemoral Venous Obstruction: Three- to 5-Year Results of the VIRTUS Study.

Purpose: To assess the midterm patency and long-term safety of placement of a dedicated venous stent (Vici Venous Stent System) for the treatment of venous lesions of the iliofemoral outflow tract.

Materials And Methods: Patients with unilateral obstructive disease of the iliofemoral veins and a Clinical, Etiological, Anatomical, Pathophysiological class of 3 or higher or a Venous Clinical Severity Score of 2 or greater were enrolled in this prospective, multicenter, single-arm study at 23 sites in the United States and Europe. The patients were followed up for 36 months after the index procedure for the assessment of patency and up to 60 months for the assessment of safety.

Analysis of wound healing time and wound-free period in patients with chronic limb-threatening ischemia treated with and without revascularization.

Background: The traditionally reported outcomes for patients with ischemic wounds have centered on amputation-free survival. However, that discounts the importance of other patient-centered outcomes such as the wound healing time (WHT) and wound-free period (WFP). We evaluated the long-term wound outcomes of patients treated for chronic limb-threatening ischemia at our institution.

Gender Disparities in Aortoiliac Revascularization in Patients with Aortoiliac Occlusive Disease.

Background: Gender disparities have been previously reported in aortic aneurysm and critical limb ischemia outcomes; however, limited info is known about disparities in aortoiliac occlusive disease. We sought to characterize potential disparities in this specific population.

Material And Methods: Patients who underwent aortobifemoral bypass and aortic thromboendarterectomy (Current Procedural Terminology codes 35646 and 35331) between 2012 and 2019 were identified in the National Surgical Quality Improvement Program database.

High Stroke Rate in Patients With Medically Managed Asymptomatic Carotid Stenosis at an Academic Center in the Southeastern United States.

Background: Although the publication of randomized clinical trials defining the benefit of carotid endarterectomy (CEA) for asymptomatic carotid stenosis, medical management of carotid stenosis has changed significantly. With antiplatelet agents and statins, some question whether these trials are still relevant, suggesting that asymptomatic patients with >70% internal carotid artery (ICA) stenosis may do better with medial management alone, lessening the need for CEA and carotid stenting. The Vascular Quality Initiative (VQI) registry has shown that there are wide practice variations regarding the degree of stenosis that prompts surgical intervention but there are few reports of outcomes in patients who do not undergo intervention.

Analysis of a Machine Learning-Based Risk Stratification Scheme for Chronic Limb-Threatening Ischemia.

Importance: Valid risk stratification schemes are key to performing comparative effectiveness research; however, for chronic limb-threatening ischemia (CLTI), risk stratification schemes have limited efficacy. Improved, accurate, comprehensive, and reproducible risk stratification models for CLTI are needed.

Objective: To evaluate the use of topic model cluster analysis to generate an accurate risk prediction model for CLTI.
