Abstract
Objective: Gelpart is a new collagen embolic agent developed for the embolization of hepatocellular carcinoma. We report a case of meningioma that was treated with preoperative embolization using Gelpart.
Case presentation: A 49-year-old woman was referred to our hospital for general convulsion. Brain CT scan demonstrated an intracranial large mass lesion, indicating parasagittal meningioma. Angiography showed increased tumor stain fed by the left middle meningeal artery. To reduce intraoperative bleeding, preoperative embolization was performed with Gelpart. The microcatheter was navigated into the left middle meningeal artery and Gelpart mixed with contrast medium was injected manually. Gelpart injection was smooth and resulted in a significant angiographical devascularization. No complication related to the embolization occurred. Postembolization MRI showed an absence of enhancement inside the tumor, indicating ischemic change. The meningioma was totally removed two days after embolization. Despite its large size, intraoperative blood loss was minimal. Postoperative course was uneventful and the patient was discharged without any neurological deficit. The pathological diagnosis was transitional meningioma. The peritumoral vessels, 300-500 μm in diameter, were embolized with Gelpart.
Conclusion: Gelpart is useful for preoperative embolization of meningioma to reduce intraoperative bleeding.
