BACKGROUND: Mastery of microsurgical anastomosis is key to achieving good outcomes in cerebrovascular bypass procedures. Animal models (especially rodents) provide an optimal pre-clinical bypass training platform. However, the existing models for practicing different anastomosis configurations have several limitations. OBJECTIVE: We sought to optimize the use of the rat's abdominal aorta and common iliac arteries (CIA) for practicing the 3 main anastomosis configurations commonly used in cerebrovascular surgery...

IMPORTANCE: Recent publications report that perioperative initiation of statin therapy is associated with improved outcomes particularly among patients with increased cardiac risk. However, findings on associations with beta blocker (BB) initiation are mixed. OBJECTIVE: This study examines associations between perioperative statin and BB use in a national sample of patients with cardiac stents. DESIGN: Retrospective cohort study. SETTING: VA Medical Centers nationwide...

BACKGROUND: Blunt cerebrovascular injuries (BCVI) are rare with nonspecific predictors, making optimal screening critical. Radiation concerns magnify these issues in children. The Eastern Association for the Surgery of Trauma (EAST) criteria, the Utah score (US) and the Denver criteria (DC) have been advocated for pediatric BCVI screening, though direct comparison is lacking. We hypothesized that current screening guidelines inaccurately identify pediatric BCVI. METHODS: This was a retrospective cohort study of pediatric trauma patients treated from 2005-2015 with radiographically confirmed BCVI...

BACKGROUND: Patients with chronic kidney disease (CKD) have worse adverse cardiovascular outcomes after coronary artery bypass grafting (CABG). However, the adverse cardiovascular outcomes between off-pump coronary artery bypass grafting (OPCAB) versus on-pump coronary artery bypass grafting (ONCAB) in these patients have been a subject of debate. METHODS: We undertook a comprehensive literature search of PubMed, Embase, and the Cochrane Library database to identify all relevant studies comparing techniques between OPCAB and ONCAB in CKD patients...

BACKGROUND: Coronary artery disease (CAD) remains the leading cause of death in developed countries and there is an increasing number of both young and elderly patients requiring surgical treatment. Despite improvement of conventional risk stratification scores (EuroSCORE II, STS risk score), all of the calculations are estimated based on the typical population and the studies emphasize that the scales may need further investigation and modernization, as demographic changes of the population suffering from CAD are unavoidable...

BACKGROUNDS: Postoperative delirium is a common complication after surgery. However, the incidence and risk factors associated with delirium after liver resection have not been clarified. Thus, this study aimed to investigate the incidence and risk factors for delirium in patients that underwent liver resections. METHODS: This study included 196 consecutive patients that underwent a liver resection. Groups with and without delirium were compared to identify differential patient characteristics...

Prognosis after extracranial-intracranial (EC-IC) bypass surgery has only been studied for a few years and the benefits of this procedure are still controversial. In this single-center retrospective study, we examined the long-term prognosis of patients who underwent EC-IC bypass surgery. Subjects were patients with symptomatic internal carotid artery or intracranial lesion occlusive disease who underwent EC-IC bypass surgery between 1991 and 2003. Of these, long-term prognosis was examined in 57 patients (39 male, 18 female; mean age, 61...

OBJECTIVES: Studies in western healthcare settings suggest that preoperative anaemia is associated with poor outcomes after elective orthopaedic surgery. We investigated the prevalence of preoperative anaemia among patients with primary unilateral total knee arthroplasty (TKA) in Singapore and its association with length of hospital stay (LOS), perioperative blood transfusion and hospital readmission rates. METHODS: Retrospective cohort study performed in a tertiary academic medical centre in Singapore, involving patients who underwent primary unilateral TKA between January 2013 and June 2014...

BACKGROUND: Moya-moya disease in children is a cerebrovascular disorder that may cause cerebral ischemic or hemorrhage. CASE DETAILS: We report an 8-year-old boy that was admitted with the chief complaint of repeated sudden half left body paralyze. MRA showed acute thrombotic infarction in the right hemisphere and internal carotid artery stenosis in the form of puffs of smokes. Indirect revascularization surgical procedure with combination of Encephalo-myo-pial-synangiosis (EMS) and Encephalo-arterio-pial-synangiosis (EAS) was performed...

OBJECTIVE Despite established risk factors, abusive head trauma (AHT) continues to plague our communities. Cerebrovascular accident (CVA), depicted as areas of hypodensity on CT scans or diffusion restriction on MR images, is a well-known consequence of AHT, but its etiology remains elusive. The authors hypothesize that a CVA, in isolation or in conjunction with other intracranial injuries, compounds the severity of a child's injury, which in turn leads to greater health care utilization, including surgical services, and an increased risk of death...

INTRODUCTION: The rate of cerebrovascular insults is increasing, currently leaving many patients with difficulties to maintain their balance due to muscular weakness and/or poor central control. Those patients are at risk of dislocation when total hip arthroplasty (THA) is planned. Instability remains the most significant issue after primary THA especially in such groups of patients. The risk is more pronounced when other factors are added such as, older age, femoral neck fractures, avascular necrosis and/or hip osteoarthritis...

BACKGROUND: Recent scientific reports have mainly focused on the comparison between coronary artery bypass surgery (CABG) and percutaneous coronary intervention. However, the impact of type 2 diabetes mellitus (T2DM) on mortality in patients who were treated by CABG was often ignored. Therefore, we aimed to compare the long-term mortality following CABG in patients with and without T2DM. METHODS: Studies comparing the long-term adverse outcomes following CABG in patients with and without T2DM were searched from electronic databases...

BACKGROUND: Coronary artery bypass graft surgery (CABG) with mitral valve surgery is undisputed in severe ischaemic mitral regurgitation (IMR) treatment, but the controversy is whether mitral valve replacement (MVR) or mitral valvuloplasty (MVP) should be used. METHODS: Data was collected from 130 cases of severe IMR patients who underwent CABG and MVP or MVR from June 2010 to June 2015 to compare the short-term efficacy of CABG with MVP or MVR in the treatment of severe IMR patients...

Better visualisation, accurate resection and avoidance of ventriculotomy associated with use of endoscopic devices during intracardiac surgery has led to increasing interest in their use. The possibility of combining a cardio-endoscopic technique with either minimally invasive or totally endoscopic cardiac surgery provides an incentive for its further development. Several devices have been used, however their uptake has been limited due to uncertainty around their impact on patient outcomes. A systematic review of the literature identified 34 studies, incorporating 54 subjects undergoing treatment of left ventricular tumours, thrombus or hypertrophic myocardium using a cardio-endoscopic technique...

INTRODUCTION: Pulmonary embolism (PE) is a life threatening preventable medical condition involving sudden occlusion of arteries within the lungs. Systemic lupus erythematosus (SLE) is an inflammatory disorder and therefore independently poses a risk of PE. We aimed to determine the association of SLE and PE using National Hospital Discharge Survey data, a national representative sample of hospital discharges throughout the United States. METHODS: Retrospective population-based analysis was done using National Hospital Discharge Survey data for the period 2001 to 2010...

Historically, coronary artery bypass graft (CABG) surgery has been the standard revascularization method for unprotected left main coronary artery (LMCA) disease. Over the last decade, several randomized controlled trials (RCTs) have shown favorable results for percutaneous coronary intervention (PCI) with drug-eluting stent (DES) compared with CABG; however, no RCT has been conducted directly comparing DESs with medical therapy alone (MTA). Furthermore, the 2 most recently reported larger RCTs, using new-generation DESs reached somewhat conflicting conclusions comparing the 2 revascularization strategies...
