Systematic literature review comparing clinical utility of heparin-bonded expanded polytetrafluoroethylene graft with autologous saphenous vein graft for the management of below-the-knee peripheral arterial disease.

Background: This systematic literature review compares the clinical outcomes of heparin-bonded expanded polytetrafluoroethylene with autologous saphenous vein in the management of patients undergoing below-the-knee bypass to treat peripheral arterial disease.

Methods: An electronic literature search was conducted in MEDLINE and Embase to identify comparative studies in patients who underwent below-the-knee surgical bypass. Studies were screened at abstract and full text review using predefined inclusion criteria by two independent reviewers and critically appraised for risk of bias.

Management of peripheral arterial disease in the context of a multidisciplinary limb program.

Peripheral artery disease (PAD) continues to increase in prevalence worldwide due to risk factors such as advanced age, diabetes mellitus, and obesity. Critical limb ischemia (CLTI) is the advanced form of PAD that can result in a lack of healing and limb loss as the most devastating consequence. Patients with PAD, especially CLTI, benefit from multidisciplinary care to optimize outcomes by reducing cardiovascular morbidity and mortality and preventing lower extremity amputation.

The role of sealants for achieving anastomotic hemostasis in vascular surgery.

Background: During vascular interventions, connections that link arteries, veins, or synthetic grafts, which are known as an 'anastomosis', may be necessary. Vascular anastomoses can bleed from the needle holes that result from the creation of the anastomoses. Various surgical options are available for achieving hemostasis, or the stopping of bleeding, including the application of sealants directly onto the bleeding vessels or tissues.

Surgical Deep Vein Arterialization: Adding to the Armamentarium of Complex Limb Salvage.

Background: Patients with severe peripheral arterial disease with limited or nonexistent arterial runoff, the so-called "desert foot", challenge efforts at limb preservation. Deep vein arterialization (DVA) involves incorporating a venous target as an outflow to achieve revascularization in these complex patients. We report outcomes in an initial series of patients undergoing DVA as a component of surgical bypass.

Novel Therapies for Critical Limb-Threatening Ischemia.

Purpose Of Review: This review intends to discuss the latest endovascular and surgical advancement in the treatment of critical limb-threatening ischemia (CLTI).

Recent Findings: We discuss novel endovascular technological advancements such as intravascular lithotripsy, the Tack endovascular stent, the PQ Bypass DETOUR system, and the LimFlow System for deep venous arterialization (DVA) in the very high risk "no-option" CLTI population. We also discuss the increasing adoption of radial and pedal approaches for endovascular revascularization and the tibiopedal arterial minimally invasive (TAMI) technique.

The impact of the SARS-CoV-2 pandemic on the management of chronic limb-threatening ischemia and wound care.

In the wake of the coronavirus pandemic, the critical limb ischemia (CLI) Global Society aims to develop improved clinical guidance that will inform better care standards to reduce tissue loss and amputations during and following the new SARS-CoV-2 era. This will include developing standards of practice, improve gaps in care, and design improved research protocols to study new chronic limb-threatening ischemia treatment and diagnostic options. Following a round table discussion that identified hypotheses and suppositions the wound care community had during the SARS-CoV-2 pandemic, the CLI Global Society undertook a critical review of literature using PubMed to confirm or rebut these hypotheses, identify knowledge gaps, and analyse the findings in terms of what in wound care has changed due to the pandemic and what wound care providers need to do differently as a result of these changes.

Effects of Peripheral Arterial Disease Interventions on Survival: A Propensity-Score Matched Analysis Using VQI Data.

Background: Atherectomy is currently being used extensively for occlusive peripheral artery disease (PAD) interventions without proven benefits. This analysis examines the effects of atherectomy and other endovascular interventions on patient survival.

Objectives: The aim of this study is to compare overall survival for patients undergoing PAD endovascular interventions, such as plain old balloon angioplasty (POBA), stent deployment and atherectomy.

Common femoral vein obstruction secondary to femoral sheath lipoma.

Common femoral vein obstruction secondary to femoral sheath lipomas are rare. We describe the case of a 49 year-old male that presented to the clinic with a 3 month history of progressive right lower extremity pain, edema and discoloration. Venous duplex imaging was consistent with proximal venous obstruction and led to Computerized Tomographic Venography (CTV) which demonstrated a large mass obstructing the external iliac vein (EIV) and common femoral vein (CFV) consistent with a femoral sheath lipoma.

The Significance of the Global Vascular Guidelines for Podiatrists: Answers to Key Questions in the Diagnosis and Management of the Threatened Limb.

The publication of the Global Vascular Guidelines in 2019 provide evidence-based, best practice recommendations on the diagnosis and treatment of chronic limb-threatening ischemia (CLTI). Certainly, the multidisciplinary team, and more specifically one with collaborating podiatrists and vascular specialists, has been shown to be highly effective at improving the outcomes of limbs at risk for amputation. This article uses the Guidelines to answer key questions for podiatrists who are caring for the patient with CLTI.

Modern multidisciplinary team approach is crucial in treatment for critical limb threatening ischemia.

The aim of this study was to provide a brief overview of the history the multidisciplinary team approach, highlighting the benefit to the patient with critical limb threatening ischemia in relation to health care economics. Furthermore, we provided a description of the requisites and key components, showing how to build a multidisciplinary team.

A novel technique using long segment patch angioplasty maturation to increase the maturation rate of arteriovenous fistulas.

Objective: Given the superior patency of arteriovenous fistulas (AVFs) and the decreased risk of infection compared with arteriovenous grafts, the Kidney Disease Outcomes Quality Initiative guidelines have recommended the fistula-first approach. However, ∼20% to 60% of all fistulas will fail to mature. We have described our experience with a novel technique using bovine pericardial patch angioplasty to increase the rate of AVF maturation.

Digital Subtraction Angiography Prior to an Amputation for Critical Limb Ischemia (CLI): An Expert Recommendation Statement From the CLI Global Society to Optimize Limb Salvage.

Despite recent guideline updates on peripheral artery disease (PAD) and critical limb ischemia (CLI) treatment, the optimal treatment for CLI is still being debated. As a result, care is inconsistent, with many CLI patients undergoing an amputation prior to what many consider to be mandatory: consultation with an interdisciplinary specialty care team and a comprehensive imaging assessment. More importantly, quality imaging is critical in CLI patients with below-the-knee disease.

Wound Center Without Walls: The New Model of Providing Care During the COVID-19 Pandemic.

The COVID-19 pandemic poses a major challenge in delivering care to wound patients. Due to multiple comorbidities, wound patients are at an increased risk for the most extreme complications of COVID-19 and providers must focus on reducing their exposure risk. The Federal, State, and local governments, as well as payers, have urged hospitals and providers to reduce utilization of nonessential health services, but they also have given more flexibility to shift the site of necessary care to lower risk environments.

Propensity Score-Adjusted Comparison of Long-Term Outcomes Among Revascularization Strategies for Critical Limb Ischemia.

Background: Few studies have compared long-term outcomes among specific treatment modalities for critical limb ischemia. The aim of this study was to compare long-term outcomes with percutaneous transluminal angioplasty (PTA), stent placement, atherectomy, or surgical bypass in patients diagnosed with critical limb ischemia.

Methods: In this observational study using Medicare claims data, we identified incident cases with a primary critical limb ischemia diagnosis who received PTA, stent placement, atherectomy, or surgical bypass.

Drug-eluting balloon angioplasty versus uncoated balloon angioplasty for the treatment of in-stent restenosis of the femoropopliteal arteries.

Background: Stents are placed in the femoropopliteal arteries for numerous reasons, such as atherosclerotic disease, the need for dissection, and perforation of the arteries, and can become stenosed with the passage of time. When a stent develops a flow-limiting stenosis, this process is known as "in-stent stenosis." It is thought that in-stent restenosis is caused by a process known as "intimal hyperplasia" rather than by the progression of atherosclerotic disease.

Customized endovascular repair of common iliac artery aneurysms.

Open technique for elective repair of iliac artery aneurysms can be safely performed with good outcomes but not inconsequential morbidity. An endovascular approach has been shown to have both periprocedural and postoperative advantages with equivalent outcomes. Endovascular repair of common iliac arteries (CIAs) without sacrificing the hypogastric artery using an iliac branch device is a complex endovascular technique requiring a proximal seal zone that may be absent in larger CIA aneurysms.

Hypogastric Preservation During Treatment of Aortoiliac Aneurysms.

The advent of endovascular technology for treating aortoiliac aneurysms has sometimes necessitated the occlusion of the hypogastric artery to prevent an endoleak or to achieve an adequate distal seal, resulting in significant morbidity for some patients. The use of iliac branch devices, in conjunction with aortic stent grafts, has made it possible to preserve the hypogastric arteries in select patients with suitable anatomy. The purpose of this review will be to discuss the indications for hypogastric preservation during treatment of aortoiliac aneurysms, as well as highlight the key procedural steps and potential technical challenges encountered during this procedure.

Determinants of Long-Term Outcomes and Costs in the Management of Critical Limb Ischemia: A Population-Based Cohort Study.

Background The optimal treatment for critical limb ischemia remains controversial owing to conflicting conclusions from previous studies. Methods and Results We obtained administrative claims on Medicare beneficiaries with initial critical limb ischemia diagnosis in 2011. Clinical outcomes and healthcare costs over 4 years were estimated among all patients and by first treatment (endovascular revascularization, surgical revascularization, or major amputation) in unmatched and propensity-score-matched samples.
