RESUMO
Background: Knowledge regarding the course and termination of the radial artery before harvesting it for coronaryartery bypass graft surgery (CABGS) is important. The brachial artery terminates at the neck of radius into radialand ulnar arteries.Purpose of the study: To know the various patterns of anomalous division ofthe radial artery.Methods: The study included 50 upper limb specimens from the Department of Anatomy, Sree Narayana Instituteof Medical Sciences, Ernakulam. The specimens were fixed with 10% formalin solution and the radial artery wasexposed from its origin till termination and observations were noted down.Results: The present study revealed that, radial artery usually was arising from brachial artery at the level ofneck of radius. The variants observed included high bifurcation of brachial artery, division of radial artery intopalmar and dorsal branches in the forearm and anomalous course of radial artery in the region of anatomicalsnuff box.Conclusion: The present study has revealed the anomalous division and course of radial artery around the wristand anatomical snuff box and the knowledge of such anomalous course is important for diagnostic, interventionaland surgical procedures.
RESUMO
Cortical vein thrombosis (CVT) is rare and is most common in the third decade of life. Cerebral venous thrombosis may be due to a variety of pathologic conditions like deficiencies of protein S (PS), antithrombin III, protein C, factor V Leiden, prothrombin gene mutations and hyperhomocysteinemia. Protein S is a vitamin K-dependent anticoagulant present in plasma and prevent thrombosis in association with protein C. Lack of it results in venous thromboembolism (VTE) rarely causing thrombosis of cerebral venous sinuses. Our patient is a 35-year-old male who presented with focal seizures. MRI brain showed venous infarcts, and MR venogram showed extensive thrombosis of superior sagittal sinus. Later work up for hypercoagulable state showed significant Protein S deficiency.
