PURPOSE To study the efficacy of contrast MR imaging in the evaluation of central nervous system complications in the cardiopulmonary bypass patient and attempt to explain their pathophysiology based on the MR appearance and the cardiopulmonary bypass protocol. METHOD Nineteen patients were prospectively studied with contrast MR examinations the day before and 3 to 7 days after cardiopulmonar...
Whether cardiopulmonary bypass alone or together with the manipulation of the aorta produce neurological complication remains controversial. Using a domestic pig model of cardiopulmonary bypass, we investigated the immediate effects of aortic cannulation and cardiopulmonary bypass on neuronal injury in different brain regions. We compared the presence of neuronal injury in three experimental gr...
OBJECTIVE Coronary artery bypass grafting is currently the best treatment for dialysis patients with multivessel coronary artery involvement. Vasoplegic syndrome of inflammatory etiology constitutes an important postoperative complication, with highly negative impact on prognosis. Considering that these patients have an intrinsic inflammatory response exacerbation, our goal was to evaluate the ...
OBJECTIVE Adequate maintenance of hypnosis during anesthesia throughout surgery using sevoflurane alone was investigated. In addition, sevoflurane pharmacokinetics during cardiopulmonary bypass were analyzed. DESIGN This was a pilot pharmacokinetic study. SETTING Tertiary care university hospital. PARTICIPANTS The study comprised 10 patients aged between 18 and 75 years who underwent elec...
OBJECTIVES Patients with coronary artery disease and left ventricular dysfunction have high mortality when kept in clinical treatment. Coronary artery bypass grafting can improve survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study is to compare patients with left ventricular ejection fract...
PURPOSE The impact of cardiopulmonary bypass in level III-IV tumor thrombectomy on surgical and oncologic outcomes is unknown. We determine the impact of cardiopulmonary bypass on overall and cancer specific survival, as well as surgical complication rates and immediate outcomes in patients undergoing nephrectomy and level III-IV tumor thrombectomy with or without cardiopulmonary bypass. MATE...
background: liver ischemic insults are important sources of liver injuries leading to production of reactive oxygen species (ros) and mediating liver cell injury. glutathione mediated mechanisms are among the most important defense mechanisms of the liver; n-acetylcysteine (nac) provides cysteine for glutathione defense mechanisms. patients undergoing cardiac surgery are at increased risk of li...
OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...
Hypothermia and cardiopulmonary bypass has rarely been used for difficult lesions of the brain such as giant aneurysms and hemangioblastoma of the brainstem. We report a case of huge recurrent angioblastic meningioma operated under the profound hypothermia and cardiopulmonary bypass. We reviewed the complications related to hypothermia and cardiopulmonary bypass for brain lesions.
The use of cardiopulmonary bypass as an adjunct to airway surgery for non-malignant diseases in adults is not well established in the UK. We are reporting two cases which demonstrate the additional benefits of using cardiopulmonary bypass during difficult bronchoscopy and complex airway stenting. The first case presents an emergency indication for cardiopulmonary bypass in a life-threatening bu...
