Abstract
Background: Cerebral venous sinus thrombosis (CVST) is a rare but serious neurovascular disorder that can lead to life-threatening complications such as hemorrhage and cerebral edema. This condition presents with a wide array of symptoms due to the formation of blood clots in the cerebral venous sinuses, impairing the drainage of deoxygenated blood and cerebrospinal fluid from the brain.
Objective: The aim of this study was to elucidate the clinical profile and risk factors associated with CVST, enhancing the understanding of its epidemiology and facilitating better diagnostic and therapeutic strategies.
Methods: This prospective cross-sectional study was conducted at the Department of Neurology, Jinnah Postgraduate Medical Centre, Karachi, Pakistan. A total of 135 participants diagnosed with CVST were enrolled through non-probability consecutive sampling. Participants underwent comprehensive physical and neurological examinations using a structured Clinical Patient Assessment Form. Diagnostic imaging included MRI, MRV, CT, and CT venography, although the principal diagnostic tools were CT and MRV. Data collection focused on demographics, clinical manifestations, and risk factors, with all information analyzed using SPSS version 25.
Results: The study population predominantly consisted of females (74.8%) with the age group of 31-40 years being the most common (31.1%). Headache was the most frequently reported symptom (90.4%), followed by hemiparesis (53.3%) and seizures (40%). Significant risk factors included postpartum status (50.4%), iron deficiency anemia (25.9%), and genetic prothrombotic conditions (9.6%). Imaging studies revealed that the transverse sinus was the most affected site (74.1%).
Conclusion: CVST exhibits a diverse range of clinical presentations and is associated with multiple demographic and physiological risk factors. Early diagnosis and management are crucial to prevent severe outcomes. This study highlights the importance of considering a detailed clinical and risk factor profile in patients presenting with neurological symptoms to aid in timely and accurate diagnosis of CVST.
