ABSTRACT
Extracorporeal membrane oxygenation (ECMO) plays a crucial role in managing heart and respiratory failure. However, it is associated with complications such as bleeding, acute renal failure, neurological issues, and thrombosis. Cerebral venous sinuses thrombosis (CVST) is a rare condition that primarily affects young females, especially those of childbearing age. CVST can result from multiple factors, both congenital and acquired, such as pregnancy, dehydration, oral contraceptives, and the postpartum period. The most common and nonspecific symptom is headache. Notably, the occurrence of CVST during ECMO has not been documented in adult patients. In this case report, we present the case of a 29-year-old lactating mother who was admitted to our hospital with complaints and clinical features indicative of community-acquired pneumonia. Despite conventional treatment, her oxygen requirement increased; therefore, she was placed on veno-venous ECMO (VV ECMO). Her condition gradually improved, and she was extubated while still on ECMO support (Awake ECMO). However, a day later of successful weaning from ECMO, she reported blurred vision and proptosis. Magnetic resonance imaging (MRI) and MR venography (MRV) of the brain showed features suggestive of CVST. She was promptly treated with anticoagulation and later discharged with minimal residual complications. This paper emphasizes the importance of early clinical recognition and treatment with anticoagulants in cases of CVST during ECMO for improved outcomes.
ABSTRACT
BACKGROUND AND AIM: It is well known that dialysis dependent renal failure increases the likelihood of poor outcome following cardiac surgery. But the results of CABG in patients with mild renal dysfunction are not clearly established. The aim of the study is to analyze the risk of preoperative mild renal dysfunction on outcome after isolated coronary surgery. MATERIALS AND METHODS: We reviewed prospectively collected data between June 2006-Nov 2006 in 488 patients who underwent isolated CABG. We separated the data into two groups. Control group having normal renal function and study group having mild renal dysfunction (serum creatinine 1.4 mg-2.2 mg%). Among 488 patients, 412 patients were in control group and 76 patients were in the study group. RESULTS: Analysis of data showed significant postoperative complications in the mild renal dysfunction group, like increased operative mortality (7.5% vs 1.6%), increased requirement of postoperative renal replacement therapy (10% vs 1.2%), increased incidence of new onset atrial fibrillation (20% vs 4.2%) and prolonged duration of ICU stay. Multivariate analysis adjusting for known risk factors confirmed preoperative mild renal dysfunction (S.creat.1.4-2.2 mg/dl) is an independent risk factor for postoperative morbidity and mortality. (Adj. OR: 4.47; 95% CI: 1.41-14.16; P=0.010). CONCLUSION: Mild renal dysfunction is an important independent predictor of outcome in terms of in-hospital mortality and morbidity in patients undergoing CABG.
