BACKGROUND: Impaired cerebral blood flow (CBF) autoregulation during cardiopulmonary bypass (CPB) is associated with stroke and other adverse outcomes. Large and small arterial stenosis is prevalent in patients undergoing cardiac surgery. We hypothesize that large and/or small vessel cerebral arterial disease is associated with impaired cerebral autoregulation during CPB. METHODS: A retrospective cohort analysis of data from 346 patients undergoing cardiac surgery with CPB enrolled in an ongoing prospectively randomized clinical trial of autoregulation monitoring were evaluated...

PURPOSE: The purpose of this study is to observe the characteristics of intrachoroidal splitting (ICS) associated with choroidal detachment due to open-globe injury. METHODS: A retrospective, observational case series study of four eyes diagnosed with choroidal detachment exhibited ICS. The in vivo pathologic changes of the ICS were recorded during surgery. Four specimens were obtained from the inner part of the ICS region. One specimen was stained with hematoxylin and eosin; one specimen was examined under scanning electron microscopy, and the other two specimens were examined under transmission electron microscopy...

BACKGROUND: Early readmission to hospital after surgery is an omnipresent quality metric across surgical fields. We sought to understand the relative importance of hospital readmission among all health services received after hospital discharge. OBJECTIVE: The aim of this study was to characterize 30-day postdischarge cost and risk of an emergency department (ED) visit, readmission, or death after hospitalization for elective major vascular surgery. METHODS: This is a population-based retrospective cohort study of patients who underwent elective major vascular surgery - carotid endarterectomy, EVAR, open AAA repair, bypass for lower extremity peripheral arterial disease - in Ontario, Canada, between 2004 and 2015...

BACKGROUND: Hemodialysis (HD) has been shown to be an independent predictor of poor outcomes after femoropopliteal revascularization procedures in patients with chronic limb-threatening ischemia. However, HD patients tend to have isolated infrageniculate disease, an anatomic risk factor for inferior patency. We aimed to compare outcomes for HD versus non-HD patients after infrageniculate open lower extremity bypass (LEB) and endovascular peripheral vascular interventions (PVIs). METHODS: Data from the Society for Vascular Surgery Vascular Quality Initiative database (2008-2014) were analyzed...

BACKGROUND AND OBJECTIVE: In patients with peripheral artery disease requiring surgery, anaemia has been found to independently predict short and medium term higher morbidity and mortality. PATIENTS AND METHODS: We retrospectively studied all patients undergoing surgery, consecutively during 2months in 12 vascular surgery units. We analysed cardiovascular risk factors and preoperative haemoglobin. Statistical analysis was done with Kaplan-Meier for survival and logistic regression modelling to identify predictors of mortality...

Small-diameter (<6 mm) vascular grafts are increasingly needed in peripheral vascular surgery but have few successes because of acute thrombosis, incomplete endothelialization and intimal hyperplasia after implantation. This study used electrospun poly(ε-caprolactone) as the matrix material. Heparin and selenium-containing catalyst-organoselenium modified polyethyleneimine were introduced through layer-by-layer assembly in order to build a vascular graft with in situ nitric oxide (NO) generation. The aim of this study was to explore the application of the graft with improved histocompatibility and biological function for vascular implantation in rats...

INTRODUCTION: A safe, largely used practice for difficult venous access patients is positioning a catheter in deeper veins under ultrasound guide. However, the risk of complications is increased when there is a high catheter-to-vein ratio or when the insertion site is in a zone with particular anatomical/physiological characteristics. CASE DESCRIPTION: A 60-year-old woman admitted to a post-operative intensive care unit after cardiac surgery had a complicated post-operative course...

Tricuspid regurgitation (TR) is a common valvular lesion which may affect morbidity and mortality. It can be related to an intrinsic abnormality of the tricuspid valve leaflets (organic) or secondary to annular dilatation (functional). Often organic and functional TR coexist in the same patient. A long standing TR is associated with ascites, congestive hepatopathy, peripheral edema, renal failure, and abdominal fullness which significantly affect the outcome. In particular, the perioperative course may be complicated due to both the presence of comorbidities and the development of a severe postoperative right ventricle (RV) dysfunction...

OBJECTIVE: Previous studies have reported correlation between the Wound, Ischemia, and foot Infection (WIfI) classification system and wound healing time on unadjusted analyses. However, in the only multivariable analysis to date, WIfI stage was not predictive of wound healing. Our aim was to examine the association between WIfI classification and wound healing after risk adjustment in patients with diabetic foot ulcers (DFUs) treated in a multidisciplinary setting. METHODS: All patients presenting to our multidisciplinary DFU clinic from June 2012 to July 2017 were enrolled in a prospective database...

Treatment of neuropathic pain (NPP) continues to be a major challenge, and the underlying mechanisms remain to be elucidated. Previous studies have demonstrated that histone methylation is important in synaptic plasticity of the nervous system and may affect nuclear factor‑κB (NF‑κB) signaling through epigenetic mechanisms. The present study aimed to investigate the role of Jumonji C domain 6 (JMJD6), a histone demethylase, in a chronic constriction injury (CCI) model of NPP. On the third day post‑CCI surgery, a JMJD6 overexpressing lentiviral vector (LV‑JMJD6) was intrathecally injected in the rats...

A 73-yr-old man presented with intractable left hemifacial spasm of 4 yr duration. Brain magnetic resonance imaging showed significant compression of left facial nerve by the left vertebral artery (VA) and anterior inferior cerebellar artery (AICA).The patient underwent a left retrosigmoid craniotomy and a microvascular decompression of the cranial nerve (CN) VII. Intraoperatively, we found that the distal AICA had a protracted subarcuate extradural course.1 This was relieved by intra/extradural dissection...

BACKGROUND: Access to medical care, by adequate insurance coverage, has a direct impact on outcomes for patients undergoing vascular procedures. We evaluated in-hospital mortality for patients undergoing index vascular procedures before and after the Massachusetts Healthcare Reform Law (MHRL) in 2006, which mandated insurance for all Massachusetts residents, both in Massachusetts and throughout the United States. METHODS: The National Inpatient Sample was queried to identify patients undergoing interventions for peripheral arterial disease, carotid artery stenosis, and abdominal aortic aneurysms based on International Classification of Diseases, Ninth Revision, Clinical Modification procedural and diagnostic codes...

A 38-year-old woman was referred to our hospital for rheumatologic manifestations (migrant arthritis and tenosynovitis), without psoriasis or family history of psoriasis, gastroenteric manifestations, or recent genitourinary infections. The instrumental and laboratory tests have suggested a diagnosis of undifferentiated seronegative HLA-B27-positive spondyloarthritis with predominantly peripheral involvement. The symptoms were very severe and resistant to anti-inflammatory drugs and steroids. She had a history of hyaline-vascular unicentric Castleman's disease (HBV, HIV, and HHV-8 negative) treated with surgery resection...

BACKGROUND: Whether the fraction of inspired oxygen (FI O2 ) influences the risk of surgical site infection (SSI) is controversial. The World Health Organization and the World Federation of Societies of Anesthesiologists offer conflicting recommendations. In this study, we evaluate simultaneously three different definitions of FI O2 exposure and the risk of SSI in a large surgical population. PATIENTS AND METHODS: Patients with clean (type 1) surgical incisions who developed superficial and deep organ/space SSI within 30 days after surgery from January 2003 through December 2012 in five surgical specialties were matched to specialty-specific controls...

OBJECTIVE: Dementia represents a major risk factor for medical complications and has been linked to higher rates of complication after surgery. Given the systemic nature of vascular disease, medical comorbidities significantly increase cost and complications after vascular surgery. We hypothesize that the presence of dementia is an independent predictor of increased postoperative complications and higher health care costs after vascular surgery. METHODS: The Vascular Quality Initiative database was queried for all patients undergoing vascular surgery at a single academic medical center from 2012 to 2017...

OBJECTIVE: Despite improved outcomes for open repair of descending thoracic aneurysm (DTA) and thoracoabdominal aortic aneurysm (TAAA), these operations remain challenging in octogenarians. Patients unsuitable for thoracic endovascular aortic repair require open surgery to avoid catastrophic rupture. We analyzed our results for DTA/TAAA repair in these elderly patients. METHODS: Our institutional aortic database was queried to identify those ≥80 years old and those <80 years old undergoing open DTA/TAAA repair...

PURPOSE OF REVIEW: The effects of statin loading before, during or after vascular interventions on cardiovascular and renal outcomes are discussed. Furthermore, the selection of optimal statin type and dose, according to current evidence or guidelines, is considered. The importance of treating statin intolerance and avoiding statin discontinuation is also discussed. RECENT FINDINGS: Statin loading has been shown to beneficially affect cardiovascular outcomes, total mortality and/or contrast-induced acute kidney injury, in patients undergoing vascular procedures such as percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), carotid endarterectomy (CEA), carotid artery stenting, endovascular aneurysm repair, open abdominal aortic aneurysms (AAA) repair and lower extremities vascular interventions...
