Cerebral venous sinus thrombosis (CVST) is a rare disease associated with high disability and mortality rates. A subset of patients do not respond to standard anticoagulation therapy, leading to the progression of CVST with hemorrhagic stroke, which represents a major challenge for its treatment. Severe hemorrhagic (SH)‑CVST is life‑threatening due to large hematoma, edema and/or cerebral hernia. Anticoagulation or thrombolytic therapy alone may lead to further aggravation of the hematoma. Stent retriever thrombectomy combined with long‑term local thrombolysis (SRT‑LLT) has been used in certain centers for those refractory cases or patients with new intracranial hemorrhage. However, to date, no studies on SRT‑LLT treatment specifically for SH‑CVST have been performed. The aim of the present retrospective study was to specifically evaluate the effectiveness of SRT‑LLT in SH‑CVST. Between December 2013 and November 2018, SRT‑LLT was performed at our center in 8 patients with hemorrhagic CVST who did not respond to intravenous anticoagulation. The clinical characteristics, results of the radiological evaluation, details on the surgical procedure and clinical outcomes were assessed. The patients were administered systemic intravenous anticoagulation as the initial treatment following admission. SRT‑LLT was performed when their condition deteriorated with a high risk of a fatal outcome within a short time period. SRT‑LLT was performed in 8 patients, with successful recanalization confirmed by angiography. In 4 of the patients, complete recanalization was achieved, whereas in the remaining 4, recanalization was partial. There were no intraoperative complications. Two patients developed rebleeding after surgery, but they all gradually recovered. There were no treatment‑associated fatalities. Therefore, SRT‑LLT appears to be a feasible, safe and effective option for SH‑CVST and it may be used as rescue therapy for carefully selected patients with SH‑CVST.
