INTRODUCTION: Embolization is a well-established technique that facilitates the subsequent surgical removal of vascularized tumors such as juvenile angiofibroma. However, there is risk of a neurological accident during angiography and tumor embolization from the internal carotid artery. Direct intratumoral embolization may help prevent these potential side effects. METHOD: A group of 7 patients with juvenile angiofibroma vascularized through the branches of the internal carotid artery underwent direct tumoral embolization under general anesthesia. An injection made slowly with an intranasal or lateral percutaneous route with either a mixture of cyanoacrylate, lipiodal, and tungsten powder. Continuous radiographic control was used. RESULTS: This technique induced a marked devascularization and necrosis of the tumor. The technique provided useful perioperative visualization of the tumor. No neurologic sequelae were encountered. CONCLUSION: Direct intratumoral embolization deserves further consideration. This might be especially important in tumors with extracranial extension, cavernous sinus involvement, or those with small or multiple recurrences.
