Carotid Health in Patients with Cerebral Venous Thrombosis.

ABSTRACT

Background: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke and shares common risk factors with arterial strokes such as hyperhomocysteinemia, tobacco, alcohol, drugs, and hypercoagulable state. These risk factors can alter both arterial and venous health leading to the occurrence of atherosclerosis in CVT patients. Aims: To evaluate carotid hemodynamics in CVT patients. Settings and Design: Prospective hospital-based case-control study. Methods: This study included 50 consecutive CVT patients and 50 healthy controls. The demographic data, vascular risk factors, clinical data, biochemical, and radiological parameters were recorded. Carotid sonography was performed in CVT patients within the first 24 h of admission. Statistical Analysis: MedCalc 17. Results: The age of the patients was 35.04 ± 9.48 years and the controls 38.88 ± 10.41 years with male preponderance in both groups. Risk factors for atherosclerosis among patients included hyperhomocysteinemia (40 patients), diabetes mellitus (4 patients), hypertension (9 patients), alcohol (17 patients), and tobacco (21 patients). Eight patients had abnormal carotid sonography. Six had nonflow-limiting plaques, one had carotid occlusion, two had increased intimal-medial thickness, and one had increased peak systolic velocity. Among the controls, three subjects had nonflow-limiting plaques. There was no difference in carotid hemodynamic parameters between controls and patients; and those with normal and elevated homocysteine. Conclusion: This is the first study to our knowledge looking at carotid health in venous strokes. The relative risk for carotid atherosclerosis in CVT patients is higher and requires long-term follow-up for the initiation of preventive measures.
