Summary
Rheolytic thrombectomy with low-dose rt-PA offers a safe and effective endovascular treatment for severe cerebral venous and sinus thrombosis (CVST). This rapid recanalization improves outcomes in high-risk patients with CVST.
Area of Science:
- Neurology
- Interventional Neuroradiology
- Vascular Neurology
Background:
- Cerebral venous and sinus thrombosis (CVST) is a rare but serious condition, often leading to poor outcomes in high-risk patients.
- Patients with stupor, coma, or rapidly progressing neurological deficits during anticoagulation are particularly vulnerable.
Observation:
- This study reports on six high-risk CVST patients treated with rheolytic thrombectomy and low-dose recombinant tissue plasminogen activator (rt-PA).
- The procedure achieved rapid recanalization of intracranial dural sinuses with no complications.
- Two patients required a second treatment due to partial rethrombosis; preexisting hemorrhagic infarcts remained stable.
Findings:
- Two patients achieved excellent outcomes, and two had good outcomes.
- Two deaths occurred due to extensive CVST prior to treatment.
- A review of 24 cases, including this series, indicates that rheolytic thrombectomy generally leads to good or excellent outcomes.
Implications:
- Rheolytic thrombectomy combined with rt-PA is a safe and effective endovascular strategy for managing extensive CVST.
- Rapid recanalization of dural sinuses can significantly improve clinical outcomes in high-risk CVST patients.
- This approach offers a critical treatment option for a condition with historically poor prognosis.
