Study of Flow Volumes of Internal Jugular Veins in Patients with Cerebral Venous Sinus Thrombosis by Doppler Ultrasonography

Background This descriptive observational study evaluation of internal jugular flow volume in 378 cerebral venous thrombosis patients which was conducted in Vinayaka Mission Kirupananda Variyar Medical College and Hospital. Aim Assessment of flow volume in internal jugular vein by Doppler ultrasonography in cerebral venous sinus thrombosis patients and to compare it with cases of hypoplastic cerebral venous sinuses. Methodology 378 cerebral venous thrombosis patients were evaluated with GE F8 Logiq ultrasound machine and Siemens magnetom symphony 1.5 tesla MRI for IJV volume and MRI brain with MRV respectively. The patients were grouped into four categories. Result The average internal jugular vein flow volume in ml/min Mean± SD are as follows: Category A: - Right side afflicted 53.47; Right side non-afflicted 400.1; Left side afflicted 64.83; Left side non-afflicted 438.2. Category B: - Right side afflicted 101.8; Right side non-afflicted 229.6; Left side afflicted 104.3; Left side non-afflicted 190.3 Category C: - Right side afflicted 96.27; Right side non-afflicted 143.5; Left side afflicted 89.89; Left side non-afflicted 145.5 Category D: - Right side afflicted 223.6; Right side non-afflicted 471.8; Left side afflicted 228.6; Left side non-afflicted 430.2. Conclusion Doppler examination of the affected patients revealed that there was a reduction in the internal jugular vein flow volume. Hence doppler can be used as an adjunct to MRI in the evaluation of CVT
