Preoperative transarterial embolization for solitary fibrous tumor of the tongue: A case report.

Solitary fibrous tumors (SFTs) are derived from mesenchymal cells originating mainly from the pleura. Reports of bleeding SFTs in head and neck regions are rare. A number of reports have focused on tongue SFT treatments, but to the best of our knowledge, there are no reports on the usefulness of preoperative arterial embolization. Intraoperative and postoperative bleeding can also lead to airway problems. To avoid unnecessary tracheostomy and ligation of the external carotid artery, preoperative vascular embolism should be considered while removing large tumors or tumors with high blood flow. The current report outlines a case of a 32-year-old woman with a tongue solitary fibrous tumor, who underwent right lingual artery embolization with 300-500 and 500-700 µm embosphere microspheres through a vascular catheter the day before surgical resection. The encapsulated tumor was completely excised under general anesthesia with little to no bleeding during the operation.
