BackgroundThrombosis of the cerebral venous sinuses (CVST) is an uncommon form of stroke, usually affecting young individuals. Clinical features of CVST are diverse, and for this reason, high degree of clinical suspect is mandatory to diagnose the conditions.Materials And MethodsThis study was conducted over a period of 1 year (Jan 2011 to Dec 2011). This was a retrospective, observational, and noninterventional study. This study was conducted in the Department of Medicine at a tertiary care teaching center. Total 50 patients where diagnosis of CVST was confirmed by computed tomography/magnetic resonance imaging brain venogram were included in this study. All patients with diagnosis of CVST were treated according to the standard protocol and guidelines.Statistical AnalysisThe mean and standard deviation were obtained. The Chi-square test was used to analyze the data and P < 0.05 was considered as statistically significant.ResultsOf total 50 patients with diagnosis of CVST, 21 (42%) were males and 29 (58%) were females with 39 ± 10 years and 29 ± 7 years, respectively. Total 45 (90%) patients presented with symptoms of headache and vomiting, 13 (26%) had seizures, 12 (24%) had hemiplegia, and 19 (38%) had fever. A total of 13 (26%) patients had papilledema on fundoscopy. Total 9 (31%) out of 29 patients had diagnosis of CVST during peripartum period. Total 12 (24%) patients had hyperhomocysteinemia. Total 23 (46%) patients had sagittal sinus thrombosis, 10 (20%) had multiple sinus thrombosis, 16 (32%) had sigmoid/transverse sinus thrombosis. There was 1 (2%) patient who had bilateral cavernous sinus thrombosis, who presented with bilateral proptosis, conjunctival congestion, and external ophthalmoplegia with a history of acute or chronic maxillary and sphenoid sinusitis. Total 38 patients had evidence of infection in the form of fever, paranasal sinus (PNS) infections, Chronic suppurative otitis media (CSOM). Total 19 (38%) patients had a history and evidence of dehydration. Total 8 (16%) patients died during the course of treatment and 42 (84%) were discharged with partial and/or total recovery. Three (6%) patients required neurosurgical intervention in the form of decompressive craniotomy. Eight (16%) patients died with cerebral edema with transtentorial herniation. The mean age of death in male was significantly greater than in female patients with P < 0.02. Majority of patients succumbed had sigmoid, transverse, and/or multiple sinus involvement. Patients with multiple sinus thrombosis had greater case fatality rate.ConclusionsThe current study highlights the burden of CVST in the study population with headache and vomiting, which was the most common presenting complaint. The superior sagittal sinus thrombosis was the most common and bilateral cavernous sinus thrombosis was the uncommon affection in CVST. One third of female population was affected in peripartum period. The infection and/or dehydration was the most commonly associated precipitating event for development of CVST and more than one fifth of the population had evidence of hyperhomocysteinemia. Mortality was more in patients with affection of sigmoid, transverse, and/or multiple sinus involvement in male patients and superior sagittal sinus thrombosis in female patients. The treatment of CVST has to be aggressive as morbidity and mortality is relatively minimal compared with the arterial stroke.
