Summary The authors report 169 therapeutic embolizations in cases of tumoral lesions in the craniocerebral, ENT, and vertebrospinal territories. Most endovascular occlusions performed for tumoral processes are presurgical indications, with the aim of reducing hemorrhage at operation. Embolization becomes practically mandatory for nasopharyngeal angiofibromas, considerably reducing the peroperative bleeding. Indications of embolization for meningiomas must be discussed according to the size and location of the tumors: embolization is especially useful in large tumors or those inserted on the base of the skull, mainly in the middle fossa. In chemodectomas, embolization can be used presurgically or on its own when surgery becomes impossible; angiographic follow-up shows that secondary repermeabilization is frequent in spite of clinical improvement. In malignant tumors of the craniofacial region, indications of embolization must be considered with care because failure of vascularization tends to make radiotherapy less efficient; in these cases, embolization can be useful in reducing pain or to contend with cataclysmal hemorrhages.
