MethodWe identified adult CVST patients in our centers. Functional outcome and prevention strategy were extracted from medical records. Modified Rankin Scale (mRS) ≤ 1 is considered a good functional outcome.ResultsA total of 113 patients were identified. The most common presenting symptoms were headache (86.72%) and nausea/vomiting (56.63%); the top two identified risk factors were local head/neck infection (27.43%) and pregnancy/puerperal period (19.47%). The medical encounter lag time was 0.04 d-120 d. Four enrolled patients were diagnosed as CVST again, and the interval time was 3-8 years from the first time. Thrombus was most frequently seen at superior sagittal sinus (53.10%) and sigmoid sinus (50.44%). 94 (83.19%) of the patients had good outcomes. In the acute phase, 91 (80.53%) patients received low molecular weight heparin, 29 (25.66%) took aspirin, 7 (6.19%) patients were put on low molecular weight heparin and aspirin together. During our follow up (6-24 m), there were 10 (8.85%) patients who suffered from thrombotic event recurrence. For the patients > 40 years old, they tended to suffer from neurological deficit (25.00%) and stupor/coma (16.67%) (p > 0.05), with a higher rate of hemorrhage (20.83%) and death (4.16%) when compared with the younger patients (10.77% and 1.53%, separately) (p > 0.05).ConclusionFunctional outcome after CVST appears good. For the patients over 40-year-old, neurological deficit and altered consciousness were more common, accompanied by a higher rate of hemorrhage and mortality. The recurrent rate of CVST was low, longer-term follow up needed. The prevention strategy after CVST was uncertain, further studies needed.Copyright © 2020 Xiuli Chu et al.
