Subarachnoid hemorrhage secondary to cerebral venous sinus thrombosis: a report of three cases and literature review

Abstract

Objective To investigate the early clinical and imaging features, treatment strategies of subarachnoid hemorrhage secondary to cerebral venous sinus thrombosis. Methods The clinical data of 3 patients with subarachnoid hemorrhage secondary to cerebral venous sinus thrombosis, admitted to our hospital from October 2013 to March 2015, were retrospectively analyzed. One patient underwent anticoagulant therapy singly, and two underwent anticoagulation and thrombolytic therapy. Results One patient was admitted to hospital in gestation period, two patients had unknown etiology. All patients complained of headache; among them, two presented with epilepsy. Two patients with early diagnosis and treatment of anticoagulation and thrombolysis had favorable prognosis, one patient with secondary intracranial hemorrhage had good outcome after active treatment. Conclusions For those patients with onset of non-aortogenic subarachnoid hemorrhage, we must keep an eye out for underlying cerebral venous sinus thrombosis. Anticoagulant and thrombolytic therapy are the first-line treatment. It is suggested that the appropriate dosage at the appropriate time to prevent cerebral hemorrhage from occurring is necessary.
