Abstract
BACKGROUND: Our study retrospectively reviewed the presentation, neuro-radiological findings, and outcomes of eight adult patients presenting at our institution with subarachnoid haemorrhage (SAH), which was subsequently proven to be due to cortical venous thrombosis (CVT). METHODS: We reviewed the case records and neuroimaging findings of eight patients diagnosed with SAH and CVT over a span of two years at our institution, a tertiary care centre in Western India. All details pertaining to their presentation, clinical findings, neuroimaging, management, and outcome following therapy with anticoagulants were collected until patient discharge. RESULTS: There were a total of eight patients, with the average age being 34 years (range 25-42). Only one patient was female. Six patients had a history of recent binge drinking. None of the patients had a past or family history of common risk factors for thrombosis. All patients presented acutely, with headache (n=6) and seizures (n=6) being the most common presenting features, occurring in three-quarters of the patients examined. Non-contrast computed tomography (NCCT) was the initial imaging study for all but one of the patients and showed cortical SAH (cSAH) without basilar haemorrhage. Magnetic resonance imaging/magnetic resonance venography (MRI/MRV) confirmed the underlying CVT. Unfractionated heparin was used in all cases. Seven patients improved and were discharged on oral anticoagulation. The eighth patient died. CONCLUSION: Localised cSAH with sparing of basal cisterns can be a presentation for CVT. In patients with cSAH, MRI/MRV can be useful to make a diagnosis of CVT. Anticoagulation for CVT, even in the presence of SAH was related to seven out of eight patients being discharged.
