[Embolization by direct puncture of hypervascularized ORL tumors]

Direct intratumoral embolization was used to treat five patients with vascularized tumors of the head and neck: 2 nasopharyngeal angiofibroma, 2 glomus jugulare tumors and 1 hemangiopericytoma. Embolization was performed by direct puncture and intratumoral injection of a plastic mixture under angiographic control. In 4 patients, embolization was performed preoperatively. Devascularization was induced in at least 90% of the volume of these tumors, thus facilitating subsequent surgical removal of the tumor. In 1 patient, embolization was performed with palliative intent. Good regression of symptoms was obtained.
