Bypass graft

Karl Waked, Marc Schepens
During open thoracoabdominal aortic aneurysm repair (OTAAAR), there is an inevitable organ ischemic period that occurs when the abdominal arteries are being reattached to the aortic graft. Despite various protective techniques, the incidence of renal and visceral complications remains substantial. This state-of-the-art review gives an overview of the current and most evidence-based organ protection methods during OTAAAR, based on the most recent publications and personal experience. An electronic search was performed in four medical databases, using the following MeSH terms: thoracoabdominal aneurysm, TAAAR, visceral protection, renal protection, kidney, perfusion, and intestines...

The management of multiligament knee injury is a complex process starting with the adequate identification of the injury. A detailed physical and radiographic examination with a thorough understanding of knee anatomy is crucial to assess all damaged structures: anterior cruciate ligament, posterior cruciate ligament, posteromedial corner including the medial collateral ligament, and posterolateral corner including the lateral collateral ligament. Several surgical techniques have been developed throughout the years to adequately address these ligament insufficiencies...

Background: Previously, we reported that the Brompton Harefield Infection Score (BHIS) accurately predicts surgical site infection (SSI) after coronary artery bypass grafting (CABG). The BHIS was developed using two-centre data and stratifies SSI risk into three groups based on female gender, diabetes or HbA1c > 7.5%, body mass index ≥ 35, left ventricular ejection fraction < 45% and emergency surgery. The purpose of this study was to prospectively evaluate BHIS internally as well as externally...

RATIONALE: Saphenous vein graft disease remains a major limitation of coronary artery bypass graft surgery (CABG). Up to 20% of vein grafts will occlude within the first year after CABG despite standard aspirin antiplatelet therapy. However, more potent postoperative platelet inhibition with ticagrelor may improve graft patency. The goal of this study will be to evaluate the efficacy of ticagrelor, as compared to aspirin, for the prevention of saphenous vein graft occlusion following CABG...

BACKGROUND: We sought to identify the trends in bilateral internal thoracic artery use and determine the degree to which the survival advantage of bilateral internal thoracic artery revascularization persists among perceived "high-risk" patients, compared with the use of left internal thoracic artery alone. METHODS: A retrospective review was conducted of patients who underwent isolated coronary artery bypass grafting for multivessel coronary artery disease at the Mayo Clinic between January 2000 and December 2015...

BACKGROUND: Coronary artery bypass graft surgery (CABG) arterial conduits are preferred to venous conduits because of longer patency. A single internal mammary artery (SIMA) is used routinely. Bilateral internal mammary arteries (BIMA) are used less frequently. We sought to determine if BIMA were superior to SIMA. METHODS: From our regional registry of consecutive open heart surgery, we identified 47,984 patients who underwent isolated CABG from 1992-2014. Of the 1,482 BIMA patients, 1,297 were propensity matched to a cohort of SIMA patients...

Mesocardia is an extremely rare congenital cardiac anomaly of counter clockwise rotation of the heart. We report here a case of coronary artery bypass grafting in mesocardia, which has not been described in medical literature earlier. A 52 years male suffered an anterior wall myocardial infarction. Chest X Ray, 2 D Echocardiography and computed tomography of chest confirmed the presence of mesocardia. Off pump total arterial revascularization was done. Exposure of aorta and right atrium through the standard median sternotomy is very difficult in mesocardia due to cardiac rotation and should be kept in mind in this surgery...

Bioresorbable scaffolds (BRS) have been introduced to clinical practice to avoid some limitations associated with the presence of permanent metal prostheses in coronary arteries. Due to elimination of the natural vasomotion of the vessel and flow disturbance, stents impair endothelial function, increasing the risk of adverse events such as late and very late thrombosis or accelerated neoatherosclerosis. Additionally, the presence of metallic stents hinders non-invasive imaging of coronaries and may exclude the possibility of bypass graft anastomosis within the stented segment...

PURPOSE: Although Rex shunt is an effective treatment for extrahepatic portal venous obstruction (EHPVO), 4-20% children develop rebleeding postoperatively. This study was used to evaluate the surgical treatment of rebleeding after Rex shunt in our center. METHOD: From June 2008 to Jan 2017, 12 of 122 children with EHPVO underwent a second operation due to graft stenosis and occlusion after Rex shunt in our center. The abdominal ultrasound and computed tomography (CT) showed the occlusion of bypass vein in nine children, stenosis of bypass vein in two children, and the patency of bypass vein in one child with dysplasia of intrahepatic portal vein...

Blunt abdominal aortic injury (BAAI) is extremely rare. Three known treatments of BAAI exist: medical treatment, conventional surgical treatment, and endovascular treatment. Outcomes of medical and conventional surgical treatments, such as bypass graft, thrombectomy, and intimal suture, were not satisfactory. A 47-year-old man presented with multiple injuries after a high-speed vehicular accident. He was diagnosed with the traumatic aortic injury to be an intra-mural hematoma in the bifurcation of the terminal aorta...

INTRODUCTION: Accurate dosing of protamine reversal following on-pump cardiac surgical procedures is challenging, with both excessive and inadequate administration recognised to increase bleeding risk. We aimed to examine the relationship between three ratios for heparin reversal and markers of haemostasis. METHODS: A retrospective analysis of a prospectively collected database was undertaken at a single tertiary cardiac unit, reviewing all cases of on-pump coronary artery bypass grafts and single valve replacements from 01/01/2011 to 31/12/2015...

BACKGROUND: Research into major bleeding during cardiac surgery is challenging due to variability in how it is scored. Two consensus-based clinical scores for major bleeding: the Universal definition of perioperative bleeding and the European Coronary Artery Bypass Graft (E-CABG) bleeding severity grade, were compared in this substudy of the Transfusion Avoidance in Cardiac Surgery (TACS) trial. METHODS: As part of TACS, 7,402 patients underwent cardiac surgery at 12 hospitals from 2014 to 2015...

BACKGROUND: Distal transradial access in the anatomical snuffbox has advantages over standard access in terms of patient and operator comfort levels and risk of ischemia. Radial artery preservation could be a relevant issue in patients requiring multiple radial artery procedures and coronary bypass with the use of a radial graft. One relevant drawback is the challenging puncture of a small and weak artery, with a steeper learning curve. AIM: The study was aimed at proving feasibility and safety of right and left transradial access in the anatomical snuffbox...

OBJECTIVES: Rapid-deployment aortic valve replacement (RD-AVR) potentially reduces procedure times providing excellent haemodynamic results compared to standard tissue aortic valve replacement. However, concerns have been raised regarding higher rates of postoperative pacemaker (PPM) requirement compared to standard aortic valve replacement. In this study, we sought to determine the PPM rate and its potential risk factors in RD-AVR patients. METHODS: Between 2011 and 2017, 193 patients underwent RD-AVR...

Importance: Health care spending in the United States is a major concern and is higher than in other high-income countries, but there is little evidence that efforts to reform US health care delivery have had a meaningful influence on controlling health care spending and costs. Objective: To compare potential drivers of spending, such as structural capacity and utilization, in the United States with those of 10 of the highest-income countries (United Kingdom, Canada, Germany, Australia, Japan, Sweden, France, the Netherlands, Switzerland, and Denmark) to gain insight into what the United States can learn from these nations...
