Alcohol Emergence: A Study on Various Risk Factors and Clinical Characteristics in Patients With Cerebral Venous Sinus Thrombosis From a Tertiary Care Hospital in South India

Abstract

Objective and aim Cerebral venous thrombosis (CVT) is a rare condition with significant morbidity and mortality risk involving the thrombosis of cerebral veins and dural sinuses. Its symptoms vary widely, ranging from headaches to focal neurological deficits, posing significant challenges to its diagnosis. Various contributing factors are involved in its etiology, some of which are gender specific. The clinical presentation varies widely and differs based on geographic distribution. This diversity makes CSVT challenging to diagnose, as it manifests in different ways and requires keen medical observation. Early detection is crucial for prognosis, as addressing the underlying cause can prevent further complications. This study aims to identify various causative factors and clinical presentations observed in individuals diagnosed with cerebral venous sinus thrombosis (CVST). Material and methods This prospective observational study was conducted at the Department of Neurology for a year, involving 55 patients admitted to the Neurology OPD/ER. Sample selection was done using non-probability convenience sampling. Patients aged 18 years or older presenting with symptoms indicative of CVST, confirmed by neuroimaging, were included in the study. Patients with arterial stroke, space-occupying lesions, and CVST related to pregnancy or puerperium were excluded. A detailed and structured medical history was obtained, and relevant blood investigations were conducted to find the underlying etiology. Results The study population had a mean age of 33 ± 2.04 years. The gender distribution is inclined towards 78.1% males due to the exclusion of pregnancy- or puerperium-related CVST to identify other predominant risk factors. 87.2% of the patients presented acutely, primarily with headaches (94.54%), and 67.2% had seizures within a week of admission. Prothrombotic conditions (45.4%) were the prevalent risk factor in the study group. Second, infections accounted for 21.8%. Alcoholism was seen in 52.7% of the study population, but its correlation with CVST remains unclear. The superior sagittal sinus (34.5%) and transverse sinus (20%) were commonly involved in neuroimaging, with multiple sinus involvement observed in some cases. Conclusion Cerebral venous sinus thrombosis (CVST) presents with a wide range of symptoms, making diagnosis challenging. However, with modern imaging and lab tests, we can detect and treat it effectively, often with positive outcomes and minimal long-term effects. This study seeks to understand the risk factors associated with CVST, contributing to its diagnosis and management.
