OBJECT: @entity1150 ( @entity1150 ) is a common complication of @entity510 ( @entity510 ). The time period of greatest risk for developing @entity1150 after @entity510 is not currently known. @entity510 induces a prothrombotic state, which may contribute to @entity1150 formation. Using repeated ultrasound screening, the hypothesis that @entity1 would be at greatest risk for developing @entity1150 in the subacute post-rupture period was tested. METHODS: One hundred ninety-eight @entity1 with @entity510 admitted to the Oregon Health _ Science University Neurosciences Intensive Care Unit between April 2008 and March 2012 were included in a retrospective analysis. Ultrasound screening was performed every 5.2    3.3 days between admission and discharge. The chi-square test was used to compare @entity1150 incidence during different time periods of interest. @entity1 baseline characteristics as well as @entity64 severity and hospital complications were evaluated in univariate and multivariate analyses. RESULTS: Forty-two (21%) of 198 @entity1 were diagnosed with @entity1150 , and 3 (2%) of 198 @entity1 were symptomatic. Twenty-nine (69%) of the 42 cases of @entity1150 were first detected between Days 3 and 14, compared with 3 cases (7%) detected between Days 0 and 3 and 10 cases (24%) detected after Day 14 (p < 0.05). The postrupture 5-day window of highest risk for @entity1150 development was between Days 5 and 9 (40%, p < 0.05). In the multivariate analysis, length of hospital stay and use of mechanical prophylaxis alone were significantly associated with @entity1150 formation. CONCLUSIONS: @entity1150 formation most commonly occurs in the first 2 weeks following @entity510 , with detection in this cohort peaking between Days 5 and 9. Chemoprophylaxis is associated with a significantly lower incidence of @entity1150 .
