ABSTRACT
Objectives and methodology: Exact localization of superficial cortical veins is very important in planning for avoiding venousinjuries. Cod liver oil capsules were placed on anterior and posterior ends of medial and lateral border of the tumor at scalpaccording to location of tumor and thus tumor boundaries were marked. Then 3DCEMRV and 2DTOF images were taken andthen superficial cortical vein studied in marked area for comparison between both modalities of MRV and planning of surgeryfor avoiding venous injury.Results: Most of the cases were in age group 16-60 years (89%). Most common clinical manifestation was headache (86.2%)and meningioma (58.2%) was found to be most common pathology. Clear depiction and morphology of superficial corticalvein was observed in 58 cases (100%) in 3DCEMRV as compared to 2DTOF 24 cases (41.3%) P <0.001S. Clear depictionand morphology of superior sagittal sinus was observed in 58 cases (100%) in 3DCEMRV as compared to 2DTOF 33 cases(60.3%) P <0.001S. In post operative CT Head, we found 6 (10.3%) cases of venous infarction. 7 patients (12%) developedmotor weakness post operatively. In 3 cases, post operative MRV were done and found no venous injury.Conclusion: This study showed that preoperative marking of tumor area and associated venous anatomy with the help of codliver oil capsule and MRV was very helpful in planning the surgery and to avoid injury of the vein. 3DCEMRV was found to bebetter modality than 2DTOF for delineation of veins.
ABSTRACT
Introduction: Cerebral Venous Thrombosis is an importantcause of stroke in the young. The importance of recognisingthis condition is that it carries a good prognosis if recognisedand treated early. Study objective was to analyse the clinicaland etiological profile of Cerebral Venous Sinus Thrombosis.Material and Methods: Prospective cross sectional studyin patients attending OPD or emergency at a tertiary referralcentre in eastern Tamilnadu with history suggestive of CVTand in whom the diagnosis of CVT confirmed by imagingof brain (MRI and MRV) were included in the study aftermeeting the inclusion criteriaResult: Among the 33 patients included in the study, majorityaffected were young males, most common clinical presentationwas headache and most common sinus involved was superiorsagittal sinus. Pro thrombotic state was observed in 27% ofcases and alcohol addiction was found to highly prevalent inthe study population.Conclusion: Cerebral Venous Thrombois is found to besignificantly high in males and alcoholics. Compared to otherIndian studies there was not much disparity in clinical profileand risk factors.
