Although there was a trend toward higher mortality in males, this was not significant.193 No association between sex and mortality rates was seen in the recent Nationwide Inpatient Sample of 3488 patients; however, the mortality was higher in that cohort (4.39%), which contained a surprisingly large number of patients with In a larger sample of 11400 records from the Nationwide Inpatient Sample data set, the most common condition associated with CVT was pregnancy/puerperium (seen in 24.6% of patients). These women had a low mor- tality rate (0.4%), but despite this, male sex was associated with decreased mortality (2.1%) on multivariate analysis The use of the Nationwide Inpatient Sample data is limited, because only inpatient data are recorded, results may be prone to coding errors, initial stroke severity is not recorded, and information on the presence of sex-specific risk factors is undoubtedly incomplete. Currently, data on sex specific functional out- comes are lacking. Pregnancy-Associated CVT Pregnancy and the puerperium period are times of increased risk for venous thrombosis for women, including CVT. The incidence of CVT during pregnancy and the puerperium is estimated at 1 in 2500 deliveries to 1 in 10000 deliveries in Western countries, with increased odds ranging from 30% to The greatest risk periods for CVT include the third trimester and the first 4 postpar- Up to 73% of CVTs in women occur during Cesarean delivery appears to be associated with a higher risk of CVT after adjustment for age, vascular risk factors, presence of infections, hospital type, and location (OR, 3.10; 95% CI, 2.26 4.24). Future Pregnancies and Recurrence Prior guidelines have summarized the studies examining the outcome and complication rates of pregnancy in women who These studies found that the risk of complications during future pregnancies was low.
