Abstract
Background
Cerebral venous thrombosis (CVT) is a rare condition that presents with significant treatment challenges and has traditionally been managed with anticoagulation. However, for patients who fail anticoagulation or present with severe symptoms, endovascular thrombectomy (EVT) has emerged as a favorable treatment modality. This study examines the outcomes, complications, and comorbidities associated with EVT in patients with CVT.
Methods
A query of the 2015-2019 National (Nationwide) Inpatient Sample was performed for patients admitted to hospitals with ICD-10 diagnosis codes for CVT and ICD-10 procedure codes for usage of EVT. Demographic information, baseline comorbidities, complications, and discharge dispositions were compared between patients who underwent EVT and those who were managed medically.
Results
A total of 36,005 patients diagnosed with CVT were identified from 2015(Q4) to 2019. Of these patients, 325 (0.9%) received EVT. Patients who underwent EVT were older (<0.001), more likely to be female (p = 0.016), and had higher rates of diabetes mellitus (p = 0.012), hypertension (p < 0.001), and obesity (p < 0.001). These patients also presented with more severe neurological symptoms, including higher National Institutes of Health Stroke Scale scores (p < 0.001), coma (p < 0.001), and cerebral edema (p < 0.001). Patients undergoing EVT had a higher incidence of in-hospital mortality (p = 0.007) and were less likely to be discharged routinely (p < 0.001).
Conclusions
This study found that patients with CVT who underwent EVT were older, more likely to be female, and presented with more severe neurological conditions. After controlling for severity, EVT in patients with CVT was associated with significant risks, including higher rates of complications and inpatient mortality. Although EVT is associated with significant risks, the findings of this study suggest that its outcomes may reflect the severity of the underlying condition rather than the procedure itself. Careful patient selection and individualized management strategies are essential for optimizing outcomes in this high-risk population.
