Safe management of carotid body tumor resection without preoperative embolization: an Ecuadorian high-altitude cities experience

Abstract

Carotid body tumors (CBTs) are a neoplasm that affects the carotid glomus. This study aims to improve the management of CBTs in Ecuador. This single-center, retrospective observational study was conducted at the Instituto de la Tiroides y Enfermedades de Cabeza y Cuello (ITECC). We included adults with CBTs, between January 2019 and August 2022. A total of 15 patients with CBTs were included. All patients were females living at high altitudes (>2500 m). In the Shamblin classification, 12 tumors were type II, and 3 were type III. Complete tumor resection was performed in all patients without pre-operative embolization. All patients had benign CBTs with a mean follow-up of 17, 73 months. In a time when the medical cost is high mainly in low-income countries such as Ecuador, further investigation should be undertaken in the form of randomized prospective trials to answer who would benefit from the pre-TAE procedure.

Management and Clinical Outcomes of Carotid Body Tumors: Insights from a Single-Center Study

“…Factors that predispose CBT remain unclear, despite many studies exploring possible risk factors such as gender, altitude, and hereditary diseases (10). A recent study of 42 patients showed that females are more likely to develop CBT than males (p=0.04) (11).…”
