Endovascular treatment for hemorrhagic cerebral venous sinus thrombosis: experience with 9 cases for 3 years.

We experienced a series of patients with hemorrhagic CVST, who were successfully treated with endovascular treatment (EVT). The aim was to explore the best scheme for the future through our treatment data of hemorrhagic CVST.A retrospective analysis was conducted, selecting nine hemorrhagic CVST patients, who were mainly treated with EVT. Characteristics of hemorrhagic CVST were recorded, including risk factors, thrombus location, presenting symptoms, and treatment details included type of EVT. We also recorded clinical outcomes, degree of sinus recanalization, thrombus recurrences, periprocedural complications, degree of neurological deficit at last follow-up.Catheter thrombolysis and mechanical thrombectomy were applied in all of the nine hemorrhagic CVST patients, stent retriever was used in 7 patients, one of them combined with balloon-assisted thrombectomy. Besides EVT, two patients accepted emergency surgical decompression, one in the local hospital, and the other in our hospital. The follow-up duration ranged from 4 to 28 months. All of them have a neurological and symptomatic improvement, 6 patients have a good outcome, the rest 3 patients have a poor outcome, no thrombus recurrences and death in them. Seven patients had complete recanalization and two patients had partial recanalization at last follow-up.EVT is an effective and safe procedure for potentially catastrophic hemorrhagic cerebral venous sinus thrombosis.
