In our study, we found that Dexmedetomidine infusion for sedation after CABG under cardiopulmonary bypass can be useful in the prevention of kidney injury. Conventional renal function tests, including blood urea nitrogen, serum creatinine, urine output and creatinine clearance rate measurements typically may not detect the development of acute kidney dysfunction in the first 48-h postoperative period. Differences were detected in renal function in the early postoperative period and the development of acute kidney injury, as determined by measurements of blood NGAL levels, was significant and dose-dependent.
Surgical management of cardiac myxoma gives excellent results. In selected cases, a conservative approach may be adequate. Despite the scarcity of the neoplastic properties, careful follow-up is necessary.
Since acute type A aortic dissection with coronary involvement is associated with high mortality rate, immediate coronary artery bypass grafting and aortic repair is a safe and reliable approach to these challenging group of patients.
We report a case of a 37-year-old sheep-raising man with a cardiac hydatid cyst involving the basal interventricular septum causing biventricular outflow obstruction. He suffered from multi-organ hydatidosis and underwent cerebral hydatid cyst extirpation and right nephrectomy for renal echinococcosis. The diagnosis of the cyst was obtained by echocardiography and magnetic resonance imaging. The diagnosis was confirmed by positive hemagglutination test. He was operated on for cardiac hydatid cyst using enucleation and capitonnage procedure under extracorporeal circulation. The morbidity was complete atrioventricular block, necessitating VDD pacemaker implantation. This was followed by medical treatment with albendazole (400 mg/day).
There is a high frequency of pseudoaneurysm formation in patients with Behçet's disease and their inflammed and fragile tissues are difficult to manipulate. Five patients with Behçet's disease were referred to our cardiovascular surgery department for coronary artery bypass grafting (CABG). Three of them were operated and two were treated medically. Patients that were managed medically had left anterior descending (LAD) lesions below 80% and their stable angina pectoris responded well to medication. There was no early mortality and morbidity. One patient developed pseudoaneurysm of ascending aorta and femoral artery. This patient died in the late postoperative period. At follow-up the operated patients were in Canadian Cardiovascular Society (CCS) Class I, while the medically treated patients were in CCS Class II. Mean follow-up period was 41 +/- 36.21 months. Coronary artery disease (CAD) is extremely rare detected in patients with Behçet's disease. The affected patients are usually young males. Coronary artery bypass grafting is also rarely performed in these patients and long-term results of such operations are not available in the literature. We present five patients with Behçet's disease that had CAD, three operated and two medically treated, and report their long-term results. We suggest a conservative approach in patients with Behçet's disease because of the high risk of pseudoaneurysm formation in the postoperative period. If CABG cannot be avoided we recommend operating the patients on the beating heart with minimal aortic manipulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
