ABSTRACT
PURPOSE: Cerebral venous sinus thrombosis (CVST) is a rare but life-threatening condition. Mechanical thrombectomy is a treatment option for patients who deteriorate or do not improve despite anticoagulation treatment or those who have a major contraindication to anticoagulation. The purpose of this study was to describe the authors' 5 years of experience in treating CVST with vacuum aspiration thrombectomy without thrombolysis. MATERIALS AND METHODS: For this retrospective study, data were collected from consecutive patients with CVST who received anticoagulation as initial medical treatment and were treated with vacuum aspiration thrombectomy without thrombolysis. Patients were followed up at 3 months and after 1 year. RESULTS: The 9 patients included in the study had a median age of 37 years, and 5 were women. All 9 patients had headaches at presentation; 7 had focal neurologic deficits, and 7 had intracranial hypertension. Risk factors for CVST were identified in 8 patients, and poor prognostic factors were identified in 7 patients. In the 9 patients, 24 CVST locations were treated; complete (70.8%) or partial (29.2%) recanalization was achieved in all CVST locations. No procedure-related complications occurred. One patient died of parenchymal hemorrhagic transformation of CVST and vasogenic edema, 6 hours after the procedure. Two patients required neurosurgical intervention. After 1 year (range, 13-30 months), all 8 surviving patients had good functional outcomes (modified Rankin Scale score 0-2). CONCLUSIONS: For appropriately selected patients with CVST, vacuum aspiration thrombectomy without thrombolysis seemed to be an effective therapy.
