BackgroundLiver transplantation is among the treatment options for end-stage liver disease. Limited organ donation in our country has resulted in an increased performance of living donor liver transplantations. This case report describes a left transverse cerebral venous sinus thrombosis diagnosed in a living donor hepatectomy patient. PatientA 45-year-old man underwent right lobe hepatectomy of a 330-g graft for living donor liver transplantation to his 55-year-old hepatitis B virus–positive brother. On the first postoperative day, without any surgical problems he presented with loss of consciousness. Previous medical history was unremarkable. Neurology consultation revealed lethargy and an acute confusional state. Cerebral magnetic resonance imaging venography showed signal alterations in the left transverse sinus wherein thrombosis was diagnosed. Heparin infusion initiated for antithrombotic treatment was adjusted to provide a 1.5 to 2-fold increased baseline activated partial thromboplastin time. On the second day of treatment has clinical status improved and he was discharged on the, fifth day on oral anticoagulant (warfarin) therapy for outpatient follow-up. ResultsCerebral venous sinus thrombosis is a rare disease with variable clinical onsets. Surgical procedures are among risk factors. An early diagnosis is essential to achieve low mortality and morbidity rates.
