Ultrasound-guided versus anatomic landmark-guided percutaneous femoral artery access.

Background: The use of percutaneous arterial access for endovascular procedures has broad applications, from diagnostic angiography in the coronary and peripheral arteries, to thromboembolectomy in people with ischemic stroke and percutaneous coronary intervention in those with acute myocardial infarction. The rise of these procedures worldwide underscores the importance of obtaining precise and timely arterial access while minimizing the risk of adverse events. Traditionally, anatomic landmarks, such as the anterior superior iliac spine and symphysis pubis, have guided percutaneous common femoral artery (CFA) access, along with manual palpation of the pulse and fluoroscopy to confirm bony landmarks.

Accuracy of presenting symptoms, physical examination, and imaging for diagnosis of ruptured abdominal aortic aneurysm: Systematic review and meta-analysis.

Objectives: Ruptured abdominal aortic aneurysm (rAAA) is a life-threatening condition, and rapid diagnosis is necessary to facilitate early surgical intervention. We sought to evaluate the accuracy of presenting symptoms, physical examination signs, computed tomography with angiography (CTA), and point-of-care ultrasound (PoCUS) for diagnosis of rAAA.

Methods: We searched six databases from inception through April 2021.

Disability, pain, and wound-specific concerns self-reported by adults at risk of limb loss: A cross-sectional study using the World Health Organization Disability Assessment Schedule 2.0.

Introduction: There has been limited study of patient-reported outcomes (PROs) in patients at risk of limb loss. Our primary objective was to estimate the prevalence of disability in this patient population using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.

Structure, processes, and initial outcomes of The Ottawa Hospital Multi-Specialist Limb-Preservation Clinic and Programme: A unique-in-Canada quality improvement initiative.

In 2017, The Ottawa Hospital initiated a unique-in-Canada quality improvement initiative by opening a novel, multi-specialist limb-preservation clinic. We sought to describe the structure, processes, and initial outcomes of the clinic and evaluate whether it is achieving its mandate of providing high-quality wound clinical care, education, and research. We conducted a descriptive prospective cohort study alongside a nested study of 162 clinic patients requiring serial assessments.

Antithrombotic regimens in females with symptomatic lower extremity peripheral arterial disease: protocol for a systematic review and meta-analysis.

Introduction: Patients with peripheral arterial disease (PAD) are at increased risk for systemic arterial thromboembolic events. Females represent a unique subset of patients with PAD, who differ from males in important ways: they have smaller diameter vessels, undergo lower extremity bypass less frequently and experience higher rates of graft occlusion, amputation and mortality than males. Females also trend towards higher rates of major coronary events and cardiovascular mortality.

From cellular function to global impact: the vascular perspective on COVID-19.

Since COVID-19 was declared a pandemic a year ago, our understanding of its effects on the vascular system has slowly evolved. At the cellular level, SARS-CoV-2 - the virus that causes COVID-19 - accesses the vascular endothelium through the angiotensin-converting enzyme 2 (ACE-2) receptor and induces proinflammatory and prothrombotic responses. At the clinical level, these pathways lead to thromboembolic events that affect the pulmonary, extracranial, mesenteric, and lower extremity vessels.
