Paragangliomas are highly vascularized usually benign neoplasms originating from the sympathoadrenal and parasympathetic paraganglia of the autonomic nervous system. When resectable, the management of these tumors consists of surgical ablation preceded by transarterial embolization. The aim of this article is to describe a novel treatment strategy combining intralesional percutaneous embolization with dissection using ultrasound scissors. The case of a 74-year-old women presenting with a Shamblin type III carotid body paraganglioma is presented. The combined approach of percutaneous embolization and ultrasound scissors permitted complete resection of the tumor with preservation of both the internal and external carotid artery, without postoperative cranial nerve deficits and with minimal blood loss. Preoperative intralesional embolization with a liquid embolic agent less than 24 h prior to surgical intervention in combination with ultrasound scissors appears to be an excellent strategy for surgical management of carotid body paragangliomas.
