Transverse sinus thrombosis after posterior fossa surgery for cerebellar tumor treated by endovascular thrombectomy. A case report.

Dural sinus thrombosis is a rare complication after posterior fossa surgery, particularly in cerebellar tumour surgery. The authors describe the case of a young male patient who presented a postoperative neurological deterioration due to transverse sinus thrombosis after surgery for cerebellar medulloblastoma. He was treated by mechanical clot thrombectomy using an endovascular catch system technique without anticoagulation therapy. Final angiographic recanalization was obtained. This kind of endoluminal mechanical revascularization is an efficacious method to treat dural sinus thrombosis during perioperative time but speed in diagnosis is crucial for clinical outcome.
