Abstract

Purpose:

This study aimed to evaluate the efficiency and safety of stent-assisted repeated aspiration thrombectomy (SARA) in treating cerebral venous sinus thrombosis (CVST).

Materials And Methods:

We conducted a retrospective analysis of 13 CVST patients treated with the SARA technique between May 2020 and May 2024. Outcomes assessed included technical recanalization rates, procedure-related complications, symptomatic intracranial hemorrhage and functional outcomes at 90 days.

Results:

The mean procedure time was 159.9 ± 22.4 (95%CI, 146.3-173.4) minutes. According to TO-ACT criteria, per-patient primary angiographic outcomes were: complete recanalization in 8/13 patients (61.5%, 95%CI 30.9%-92.1%), partial recanalization in 5/13 patients (38.5%, 95%CI 7.9%-69.1%), and none in 0/13 patients (0%). Successful recanalization rates were as follows: superior sagittal sinus (72.7%, 8/11), torcular herophili (75.0%, 6/8), lateral sinus (81.8%, 9/11), internal jugular veins (100%, 4/4), and straight sinus (80.0%, 4/5). No procedure-related complications or symptomatic intracranial hemorrhage (sICH) were observed, and 84.6% (11/13) of patients achieved favorable clinical outcomes at 90 days.

Conclusions:

The SARA technique appears to be a safe and effective endovascular treatment for CVST.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
