Risk Factors for Hospital Readmission Following Noncardiac Surgery: International Cohort Study.

Objective: To determine timing and risk factors associated with readmission within 30 days of discharge following noncardiac surgery.

Background: Hospital readmission after noncardiac surgery is costly. Data on the drivers of readmission have largely been derived from single-center studies focused on a single surgical procedure with uncertainty regarding generalizability.

Incidence and Risk Factors of Chronic Postoperative Pain in Same-day Surgery: A Prospective Cohort Study.

Background: The amount of same-day surgery has increased markedly worldwide in recent decades, but there remains limited evidence on chronic postsurgical pain in this setting.

Methods: This study assessed pain 90 days after ambulatory surgery in an international, multicenter prospective cohort study of patients at least 45 yr old with comorbidities or at least 65 yr old. Pain was assessed using the Brief Pain Inventory.

Mortality and major postoperative complications within 1 year after vascular surgery: a prospective cohort study.

Introduction: Patients undergoing vascular procedures are prone to developing postoperative complications affecting their short‑term mortality. Prospective reports describing the incidence of long‑term complications after vascular surgery are lacking.

Objectives: We aimed to describe the incidence of complications 1 year after vascular surgery and to evaluate an association between myocardial injury after noncardiac surgery (MINS) and 1‑year mortality.

Acute aortic intraluminal thrombus with embolisation and lower-limb ischaemia following intravenous iron sucrose infusion reaction.

A woman in her 50s developed iron deficiency anaemia. Her medical history included hypertension, asthma and remote postpartum pulmonary embolism. There was a strong family history of atherosclerosis.

Methods: Patients discharged from Hamilton General Hospital (Hamilton, Ontario) between April 2016 and September 2017 following severe limb ischemia requiring urgent/emergent revascularization were identified via the Local Health Integration Network CorHealth database, with supplemental information from chart review.

Results: A total of 158 patients admitted for urgent/emergent revascularization were identified (148 alive at discharge).

Elevated plasma levels of NT-proBNP in ambulatory patients with peripheral arterial disease.

N-terminal pro B-type natriuretic peptide (NT-proBNP), a cardiac disease biomarker, has been demonstrated to be a strong independent predictor of cardiovascular events in patients without heart failure. Patients with peripheral arterial disease (PAD) are at high risk of cardiovascular events and death. In this study, we investigated levels of NT-proBNP in patients with PAD compared to non-PAD controls.

Urinary fatty acid binding protein 3 (uFABP3) is a potential biomarker for peripheral arterial disease.

Plasma levels of fatty acid binding protein 3 (pFABP3) are elevated in patients with peripheral artery disease (PAD). Since the kidney filters FABP3 from circulation, we investigated whether urinary fatty acid binding protein 3 (uFABP3) is associated with PAD, and also explored its potential as a diagnostic biomarker for this disease state. A total of 130 patients were recruited from outpatient clinics at St.

A Canadian multicenter experience describing outcomes after endovascular abdominal aortic aneurysm repair stent graft explantation.

Background: Most studies describing the outcomes after endovascular abdominal aortic aneurysm repair (EVAR) explantation have been from single, high-volume, centers. We performed a multicenter cross-Canadian study of outcomes after EVAR stent graft explantation. Our objectives were to describe the outcomes after late open conversion and EVAR graft explantation at various Canadian centers and the techniques and outcomes stratified by the indication for explant.

Fibrin and Thrombin Sealants in Vascular and Cardiac Surgery: A Systematic Review and Meta-analysis.

Objective: In vascular and cardiac surgery, the ability to maintain haemostasis and seal haemorrhagic tissues is key. Fibrin and thrombin based sealants were introduced as a means to prevent or halt bleeding during surgery. Whether fibrin and thrombin sealants affect surgical outcomes is poorly established.

A National Canadian Survey of Antithrombotic Therapy After Urgent and Emergent Limb Revascularization.

Patients with peripheral artery disease who undergo urgent or emergent lower extremity revascularization have the highest risk of major adverse cardiac and limb events. Although available evidence suggests that antithrombotic therapy reduces this risk, optimal antithrombotic therapy is unclear. In this report, we aim to describe current practice patterns for use of antithrombotic therapies after urgent/emergent peripheral artery revascularization.

The economic burden of inpatient diabetic foot ulcers in Toronto, Canada.

Methods: We conducted a multicenter study of all diabetic foot ulcer patients admitted to general internal medicine wards at seven hospitals in the Greater Toronto Area, Canada from 2010 to 2015, using the GEMINI database.

A Systematic Review of Economic Evaluations in Vascular Surgery.

Background: With increasing healthcare costs and the emergence of new technologies in vascular surgery, economic evaluations play a critical role in informing decision-making that optimizes patient outcomes while minimizing per capita costs. The objective of this systematic review is to describe all English published economic evaluations in vascular surgery and to identify any significant gaps in the literature.

Methods: We conducted a comprehensive English literature review of EMBASE, MEDLINE, The Cochrane Library, Ovid Health Star, and Business Source Complete from inception until December 1, 2018.

YouTube as a source of patient information for abdominal aortic aneurysms.

Objective: Patients are increasingly referring to the Internet after a diagnosis of vascular disease. This study was performed to quantitatively define the accuracy and reliability of information on YouTube regarding abdominal aortic aneurysms (AAA).

Methods: A systematic search of YouTube was conducted using multiple AAA-specific keywords.

Factors relating to the publication rate of abstracts presented from 2012 to 2015 at the Society for Vascular Surgery Annual Meeting.

Objective: The Society for Vascular Surgery's Annual Meeting acts as a means of disseminating research findings among vascular surgeons through the presentation of research abstracts. Following presentation at the meeting, research is often compiled into a full-text manuscript and submitted to a peer-reviewed journal. However, not all abstracts accepted to the Vascular Annual Meeting (VAM) eventually have a corresponding full-text publication.

Steroids in cardiac surgery trial: a substudy of surgical site infections.

Purpose: Postoperative infection, particularly in cardiac surgery, results in significant morbidity, mortality, and healthcare cost. Identification of novel predictors of postoperative infection can target high-risk populations for prophylactic intervention.

Methods: Steroids in cardiac surgery (SIRS) was a multi-centre randomized-controlled trial assessing intraoperative administration of methylprednisone during cardiac surgery, which enrolled 7,507 patients across 80 centres in 18 countries.

Meta-analysis of nontumescent-based versus tumescent-based endovenous therapies for patients with great saphenous insufficiency and varicose veins.

Objective: The objective of this study was to compare the nontumescent-based endovenous therapies with the standard tumescent-based endovenous therapies in regard to clinical effectiveness and procedural outcomes in patients with saphenofemoral incompetence and varicose veins.

Methods: The following databases were searched for studies that were randomized or quasi-randomized trials comparing nontumescent-based endovenous procedures with those requiring tumescence: Cochrane Central Register of Controlled Trials (1950-January 2017), MEDLINE (1946-January 2017), and Embase (1950-January 2017). There were no restrictions based on language or publication status.

Management of Lower Extremity Ischaemia During Type A Dissection Repair.

Introduction: Type A aortic dissection can present with malperfusion syndrome. Lower limb ischaemia may resolve with repair of the dissection; however, the long duration of repair and/or persistent ischaemia may leave tissue at risk of necrosis with potential for substantial morbidity.

Report: Here, the case of a 67 year old man who presented with a Type A aortic dissection with malperfusion of the lower extremities is described.

Optimization of rifampin coating on covered Dacron endovascular stent grafts for infected aortic aneurysms.

Objective: In the treatment of an infected aorta, open repair and replacement with a rifampin-impregnated Dacron vascular graft decrease the risk of prosthetic graft infections, with several protocols available in the literature. We hypothesize that the same holds true for endovascular aneurysm repair, and after studying and optimizing rifampin solution concentration and incubation period to maximize the coating process of rifampin on Dacron endovascular stent grafts (ESGs), we propose a rapid real-time perioperative protocol.

Methods: Several prepared rifampin solutions, including a negative control solution, were used to coat multiple triplicate sets of Dacron endovascular aortic stent grafts at different but set incubation periods.

Level of clinical evidence presented at the Society for Vascular Surgery Annual Meeting during a 5-year period (2012-2016).
