Decompressive craniectomy in hemorrhagic cerebral venous thrombosis: clinicoradiological features and risk factors

Area of Science:

• Neurosurgery
• Neurology
• Vascular Neurology

Background:

• Severe hemorrhagic cerebral venous thrombosis (CVT) is a critical condition requiring effective interventions.
• Decompressive craniectomy (DC) is a recognized life-saving treatment for severe hemorrhagic CVT.
• Understanding clinicoradiological features and risk factors is crucial for optimizing surgical outcomes in hemorrhagic CVT.

Purpose of the Study:

• To analyze clinicoradiological features and surgical outcomes in patients with severe hemorrhagic CVT treated with DC.
• To identify potential risk factors associated with poor outcomes in this severe subtype of CVT.
• To provide further evidence supporting the benefits of DC for hemorrhagic CVT.

Main Methods:

• Retrospective analysis of 58 patients with severe hemorrhagic CVT who underwent DC between January 2005 and March 2015.
• Evaluation of clinical features, radiological findings (including lesion volume, bilaterality, and depth), and surgical outcomes.
• Risk factor analysis for predicting outcomes, categorizing patients based on hemorrhage-dominated versus edema-dominated lesions.

Main Results:

• 56.9% of patients achieved favorable outcomes after 6 months; 8 patients (13.8%) died.
• Hemorrhage-dominated lesions (46.6%) and deep cerebral venous involvement were significantly associated with poor outcomes (p = 0.026).
• Mean patient age was 39.7 ± 12.5 years, with a mean duration from symptom onset to surgery of 3.3 ± 1.9 days.

Conclusions:

• Decompressive craniectomy is an effective, life-saving treatment for severe hemorrhagic CVT, associated with favorable outcomes.
• Hemorrhage-dominated lesions and deep cerebral venous involvement are significant predictors of poor outcomes in this patient group.
• Further research into risk stratification and tailored treatment strategies for hemorrhagic CVT is warranted.
