Assessing Resident Impact on Surgical Outcomes in Below-the-Knee Amputations Based on Operative Autonomy

Gradual increases in resident autonomy with attending physician oversight is crucial to developing safe and competent surgeons1. The Veterans Affairs Surgical Quality Improvement Program (VASQIP) follows surgical outcomes within the VA. We set forth to examine the VASQIP database to compare outcomes between resident independent cases and nonindependent cases during below-the-knee amputations (BKA).

A Contemporary Comparison of Cyanoacrylate, Radiofrequency, and Endovenous Laser Ablation on Healing of Active Venous Ulceration

The goal of this study is to compare the healing rates of active lower extremity venous ulcers for patients receiving one of three ablation methods, compare their complications, and identify factors affecting successful healing and prevention of recurrence.

Intimal Hyperplasia of Arteriovenous Fistula

Intimal hyperplasia (IH), a crucial histopathological injury, forms the basis of vascular stenosis and thrombogenesis. In addition, it is common in maladies such as stenosis at the anastomosis of arteriovenous fistula and restenosis after angioplasty. Various cellular and noncellular components play critical parts in the advancement of IH. This article reviews the distinctive components of IH, such as endothelial dysfunction, multiplication, and movement of vascular smooth muscle cells. Finally, in addition to synthesis of large amounts of extracellular matrix and inflammatory responses, which have frequently been studied in recent years, we offer a premise for clinical treatment with vascular smooth muscle cells.

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

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.

The Effect of 12-Week Treatment with Intermittent Negative Pressure on Blood Flow Velocity and Flowmotion, Measured with a Novel Doppler Device (Earlybird). Secondary Outcomes from a Randomized Sham-Controlled Trial in Patients with Peripheral Arterial Disease

Treatment with intermittent negative pressure (INP) is proposed as an adjunct to standard care in patients with peripheral arterial disease (PAD). The aims of this study were to evaluate the applicability of a novel ultrasound Dopplerdevice (earlybird) to assess blood flow characteristics in patients with PAD during a treatment session with INP, and whether certain flowproperties could determine who could benefit from INP treatment.

Postoperative Anticoagulation in Vascular Reconstructions Associated with Malignancies

The invasion of truncal arteries and veins by malignant neoplasms is rare and the surgical treatment remains a challenge. Several techniques can be used to re-establish blood flow in a resected vessel and choice of the ideal vascular substitute frequently arises a debate. Comparative studies between prosthetic and autologous grafts disclose conflicting patency results. The aim of this study is to compare patency outcomes of vascular reconstructions performed using autologous or prosthetic replacement grafts in surgical oncology, in light of a standardized antithrombotic protocol used in our institution since 1997.

Reliability and Safety of Individualized Follow-up Based on the 30-day Computed Tomography Angiogram after Endovascular Aneurysm Repair

Most patients undergo uneventful surveillance after endovascular aneurysm repair (EVAR), and therefore, unmodified surveillance protocols are ineffective. An example of a modified follow-up protocol was introduced by the European Society for Vascular Surgery (ESVS) in January 2019. One feature of this protocol is that for the patients with adequate sealing and without any detectable endoleak at 30 days, the next scheduled follow-up could be at 5 years. The purpose of this study was to analyze retrospectively the applicability of this protocol.

Quality Assessment of Online Resources for Thoracic Outlet Syndrome Patients

The internet has become a leading resource for patients, to research information about their medical conditions. Access to inaccurate information can lead to miscommunication, poor patient satisfaction and effect shared decision-making with the provider. This study seeks to evaluate the quality and readability of patient resources that appear in the top search results for Thoracic Outlet Syndrome (TOS).
