Background There have been well-documented implications of race/ethnicity on the outcome of various vascular diseases. Little literature has examined the effect of race/ethnicity on venous disease. Iliac vein stenting is an emerging technology in treating chronic venous insufficiency. To further characterize this disease and its treatment, we chose to study the effect of selected clinical factors including race/ethnicity on the early complications of non-thrombotic iliac vein stenting. Methods In this observational study, data analysis was performed for 623 patients with chronic venous insufficiency who underwent iliac vein stenting during the time period from August 2012 to September 2014...

Objectives To evaluate the impact of renal artery morphology on fluoroscopy time in chimney endovascular aneurysm repair. Methods Morphology of renal artery was retrospectively quantified in the preoperative CT angiography. Renal artery angulation, ostial diameter, severity of ostial stenosis, main renal artery length, and tortuosity were analyzed with a 3D workstation. The main measure outcome was fluoroscopic time as an indicator of complexity. Uni- and multivariate logistic regression analyses were performed to determine predictors of longer fluoroscopy...

Objectives This study evaluates the effect of stent sizing with CT-scan on the incidence of restenosis in peripheral arterial disease. Methods This retrospective study included 59 patients with 66 arterial lesions who underwent a endovascular procedure for peripheral arterial disease between April 2013 and October 2013. All patients had de novo iliac or femoral lesions, were candidates for an endovascular procedure alone and underwent CTA preoperatively. The stent actually implanted, whose dimensions were chosen on the basis of the operator's experience on an intraoperative 2D angiography, was compared to the "ideal" stent chosen retrospectively on the basis of precise lesion sizing by the preoperative CTA...

Objective The Food and Drug Administration and the Vascular Quality Initiative still utilize fluoroscopy time as a surrogate marker for procedural radiation exposure. This study demonstrates that fluoroscopy time does not accurately represent radiation exposure and that dose area product and air kerma are more appropriate measures. Methods Lower extremity endovascular interventions ( N = 145) between 2013 and 2015 performed at an academic medical center on a Siemens Artis-Zee floor mounted c-arm were identified...

Background We report a symptomatic carotid web successfully treated with carotid endarterectomy. A healthy 43-year-old woman presented with acute-onset left-sided weakness. Carotid web was evident on computed tomography angiography as a focal filling defect in the right common carotid artery. This right common carotid artery web extended into the ICA created an eddy resulting in turbulent flow. Subsequent acute embolus formation led to embolization and acute stroke. Method Review of the literature was performed using Medline Plus and PubMed databases...

Background The level of knowledge of stroke risk factors and stroke symptoms within a population may determine their ability to recognize and ultimately react to a stroke. Independent agencies have addressed this through extensive awareness campaigns. The aim of this study was to determine the change in baseline knowledge of stroke risk factors, symptoms, and source of stroke knowledge in a high-risk Toronto population between 2010 and 2015. Methods Questionnaires were distributed to adults presenting to cardiovascular clinics at the University of Toronto in Toronto, Canada...

Objectives Abdominal compartment syndrome (ACS) is poorly identified in surgery for ruptured abdominal aortic aneurysm and an early management is crucial. The aim of this study was to validate how many risk factors were needed to predict ACS. Secondary objectives were to assess its prevalence and the 30-day mortality. Methods All patients operated for ruptured abdominal aortic aneurysm during 5 years were included. An independent committee performed a retrospective diagnosis of ACS. Eight criteria were selected from the literature, and corresponded to pre- and intraoperative period: anemia (hemoglobin lower than 10 g/dL), prolonged shock (systolic blood pressure <90 mmHg more than 18 min), preoperative cardiac arrest, obesity (body mass index > 30), massive fluid resuscitation (≥3500 mL per hour for at least 1 h) and transfusions (>10 units packed blood red cell since the beginning of the treatment), severe hypothermia (≤33℃), acidosis (pH < 7...

Introduction Acute mesenteric ischaemia is associated with a significant morbidity and mortality. Endovascular techniques have emerged as a viable alternative treatment option to conventional surgery. Our objective was to conduct a systematic review of the literature and perform a meta-analysis of reported outcomes. Methods Our review conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement standards and the protocol was registered in PROSPERO (CRD42016035667). We searched electronic information sources (MEDLINE, EMBASE, CINAHL, CENTRAL) and bibliographic lists of relevant articles to identify studies reporting outcomes of endovascular treatment for acute mesenteric ischaemia of embolic or thrombotic aetiology...

Background Prevalence of peripheral arterial disease (PAD) has dramatically increased in both developing, as well as developed countries. However, significant knowledge and practice gaps persist. In Canada, efforts to improve this knowledge level are lacking. In this study, we examine PAD knowledge in Toronto, and evaluate a pilot intervention to address the knowledge gaps. Objectives Measure PAD awareness in Toronto, and evaluate an intervention to improve PAD knowledge among the public. Methods In the context of a community-based awareness campaign, an interview-based survey was used to assess the PAD awareness among general public...

Purpose Computer tomography angiography is used to assess peripheral arterial disease. Its preference over other imaging modalities is based upon its rapid acquisition and high spatial resolution, along with ease of access. TASC II have recently updated their vascular lesion classification to include infrapopliteal lesions, and our aim is to assess the reproducibility of TASC II on infrapopliteal disease when using computer tomography angiography. Methods A retrospective analysis of a series of consecutive computer tomography angiographies was performed by seven assessors (three consultant radiologists, two consultant vascular surgeons and two vascular specialty trainees)...

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin access (9/25; 36%) were managed through the percutaneous remote access...
