Background and Objectives Carotid body paraganglioma is the common type of carotidbody tumor for which angiography, carotid artery balloon occlusion test (BOT) and tumorembolization could be considered before the surgery. We analyzed cases in a single instituteand reviewed related literature to investigate the necessity of these preoperative examinations.
Subjects and Method Medical records of patients who were diagnosed with paragangliomawere retrospectively analyzed from 2000 to 2019.
Results Sixteen patients were identified. Of the total, 14 patients underwent surgery at thisinstitute, and 13 underwent angiography. Of the 13 patients who underwent angiography, 6patients underwent carotid artery BOT, and 12 patients underwent tumor embolization. Theaverage tumor size of 6 patients who underwent carotid artery BOT was 28.7 mm, and 8 patientswho did not undergo carotid artery BOT was 30.1 mm. The average tumor size of 12 patientswho underwent tumor embolization was 29.4 mm. Two patients did not undergo tumorembolization, and their average tumor size was 30 mm. In 1 patient, both preoperative angiographyand carotid artery BOT were performed, but tumor embolization was not performeddue to spasm of tumor vessels.
Conclusion Preoperative carotid artery BOT can be performed to reduce side effects in patientswith the potential for carotid resection. In addition, tumor embolization is performed regardlessof tumor size. By reducing the amount of bleeding during surgery and reducing thesize of the tumor, it is possible to secure an appropriate surgical field of view to facilitate operationduring surgery; however, its effectiveness needs to be clearly identified.
