Preoperative Squid embolization of carotid paragangliomas with direct puncture.

Background And Purpose: Preoperative embolization of carotid paragangliomas is a common procedure in interventional neuroradiology. Direct puncture embolization has shown less morbidity and mortality than endovascular embolization and a higher percentage of devascularization. We describe our experience using Squid® as the only embolic agent in direct puncture glomus embolization.
