CVT in the Peripartum Period: A Diagnostic Dilemma

Gender Differences in Risk Factor Profile and Clinical Characteristics in 89 Consecutive Cases of Cerebral Venous Thrombosis

Gender has been shown to be an important variable in cerebral venous thrombosis (CVT) risk and significantly influences its clinical manifestations and outcome. The aim of our study was to investigate the gender-specific risk factor profile and clinical picture of this rare cerebrovascular disorder.

MATERIALS AND METHODS

We retrospectively reviewed the medical records of 89 consecutive cases of CVT at a tertiary neurology clinic in Târgu Mures, Romania, between June 2009 and January 2021 to analyze the gender-related differences in etiology, clinical presentation, and outcome.

RESULTS

Women comprised 62.5% of the cohort. Females were significantly younger than males (37.3 years versus 48.8 years, respectively, p = 0.001), and the main risk factors were hormone related in 37.9% of the cases, followed by primary thrombophilia (34.4%), smoking (25.8%), obesity (17.2%), infections (17.2%), mechanical factors (17.2%), cancer (8.6%), systemic autoimmune disorders (8.6%), and hematological disorders (8.6%). In male patients, the main risk factors were smoking (41.9%), primary thrombophilia (29%), infections (22.6%), heavy alcohol consumption (16.1%), and venous thromboembolism in the medical history (12.9%). Frequency of headache was higher in females than in males (75.9% versus 67.7%), whereas frequency of coma (6.5% in males versus 1.7% in females) and dizziness (19.4% in males versus 10.3% in females) was higher in males. CVT onset was acute in 41.4% of females and 38.7% of males. The Rankin score at discharge was significantly lower in females compared with males (0.6 versus 1.6), reflecting a more favorable short-term outcome. Mortality was 6.4% in males and 1.7% in females.

CONCLUSIONS

CVT is a multifactorial disorder that has a broad spectrum of risk factors with important gender-related differences in clinical manifestation and prognosis. Female patients, especially those with hormone-related risk factors, have a more favorable outcome than male patients.

Postpartum Cerebral Venous Thrombosis-A Single-Center Experience

Background: Cerebral venous thrombosis (CVT) is a rare variant of stroke in the general population, but an important subtype among pregnancy- and puerperium-related cases. Studies describing its risk factors and clinical characteristics are limited. The aim of our study is to disclose these aspects and compare with cases unrelated to pregnancy and puerperium. Materials and Methods: We performed a retrospective analysis including 88 consecutive cases from a tertiary neurology clinic with a diagnosis of CVT. Ten of the 88 cases (11.3%) appeared during the postpartum period. Results: The mean age of the puerperal CVT cases was 26.5 years. The main pregnancy-related risk factors besides puerperium were cesarean delivery (5/10), preeclampsia (2/10), and stillbirth (1/10). General risk factors for thrombosis, i.e., infection, smoking, and primary hypercoagulability, were identified in 50% of cases. Onset was in the first 3 weeks after delivery, with a mean value of 9.6 ± 5.6 days. Headache was present in 90% of postpartum CVT cases and in 76.1% of non-postpartum female cases. Seizures were more frequent in the postpartum group (60% vs. 34.8%). Onset was acute (<48 h) in 50% of postpartum cases and in 30.4% of the non-postpartum female group. The Rankin score at discharge was significantly lower in the postpartum group (0.22 vs. 0.7, p = 0.02), suggesting a more favorable short-term outcome. Conclusions: The early postpartum period represents an important risk for the development of CVT. Cesarean delivery and preeclampsia, besides general risk factors such as infection, smoking, and primary thrombophilia, contribute to enhanced risk. Puerperium-related CVT presents a more favorable outcome compared with CVT with other etiologies.
