Sinus Venous Thrombosis

Background: Intracranial Sino venous occlusive disease is an infrequent condition and accounts only 0.5-1% of all strokes. Objective of the study was to know the prevalence, pattern and risk factors involved in patients of cerebral sinus venous thrombosis (CSVT).Methods: Hospital databases were searched retrospectively and patients diagnosed with CSVT from December 2014 to February 2016 were identified. Data on clinical presentation, risk factor, cerebral sinus involved, hospital stay and outcome were analyzed.Results: Fifteen patients (3.4%) were identified as CSVT out of a total acute stroke case of 430. Mean age of patients was 31 years and 11 (73.3%) were males. The presenting symptoms included headache (n=14), altered sensorium (n=1) and seizures (n=5); signs included hemi paresis (n=4), papilledema (n=8) and bilateral VI nerve palsy (n=3). Majority had aseptic CSVT (n=14), and one patient had septic CSVT associated with tuberculous meningitis (TBM). Radiological findings included brain parenchyma involvement (n=8), subdural hematoma (SDH) (n=1), subarachnoid haemorrhage (SAH) (n=1) and normal brain parenchyma (n=5). Multiple cerebral sinuses were involved in seven patients. Most common site of CSVT was observed in sigmoid sinus. Risk factors included hyperhomocystenemia (n=3), protein S deficiency (n=8), protein C deficiency (n=6) and antithrombin III deficiency (n=3) as primary hypercoagulable state. ANA positive was observed in one patient and four had history of alcohol use. All fifteen patients received low molecular weight heparin (LMWH) for 1 week along with bridging oral anticoagulant. None of the patients required intrasinus thrombolysis and decompression surgery. Average hospital stay was 9 days. All had modified Rankin scale (MRS) ≤ 2 at 6 months follow up.Conclusions: Prevalence of CSVT is higher than that reported from Asian studies. Younger age and male predominance was observed. Protein S deficiency was the major risk factor for CSVT.

S Deficiency

SummaryA recent study suggests that protein S deficiency is not a risk factor for venous thrombosis. Since this unexpected finding would have important clinical implications if confirmed, we performed a case-control study with the aim to determine the prevalence of protein S deficiency in patients with thrombosis and in healthy individuals taken from the general population and the relative risk of thrombosis in protein S-deficient patients. Free protein S concentration was measured in 327 consecutive patients with at least one venous thrombotic episode and in 317 age- and sex-matched control individuals. Different normal reference ranges were obtained and adopted for men and women. Protein S deficiency was found in 3.1% (95% Cl: 1.5-5.2) of patients and in 1.3% of controls (95% Cl: 0.3-2.8). Ten patients and 4 control subjects had protein S deficiency, which determined a relative risk of thrombosis (sex- and age-adjusted odds ratio) of 2.4 (95% Cl: 0.8-7.9). When men and women were analyzed separately, the risk was 5.0 (95% CI: 0.6-43.6) and 1.6 (95% Cl: 0.4-6.7) respectively. PS-deficient men had more thrombotic episodes than women and later in life. Multivariate analysis established that sex was an independent determinant of the number of episodes, as was age, while PS deficiency was not. However sex and PS deficiency status were both determinants of age at first thrombotic episode.

SummaryThe frequency of heterozygous protein C and protein S deficiency, detected by measuring total plasma antigen, in a group (n = 141) of young unrelated patients (<45 years old) with venous thrombotic disease was studied and compared to that of antithrombin III, fibrinogen, and plasminogen deficiencies. Among 91 patients not receiving oral anticoagulants, six had low protein S antigen levels and one had a low protein C antigen level. Among 50 patients receiving oral anticoagulant therapy, abnormally low ratios of protein S or C to other vitamin K-dependent factors were presented by one patient for protein S and five for protein C. Thus, heterozygous Type I protein S deficiency appeared in seven of 141 patients (5%) and heterozygous Type I protein C deficiency in six of 141 patients (4%). Eleven of thirteen deficient patients had recurrent venous thrombosis. In this group of 141 patients, 1% had an identifiable fibrinogen abnormality, 2% a plasminogen abnormality, and 3% an antithrombin III deficiency. Thus, among the known plasma protein deficiencies associated with venous thrombosis, protein S and protein C. deficiencies (9%) emerge as the leading identifiable associated abnormalities.
