Abstract:
Objective:To explore the application of contrast-enhanced ultrasound in the preoperative evaluation of carotid body tumor (CBT).Methods:The clinical data of 13 CBT patients undergoing contrast enhanced ultrasound test and surgical treatment at Peking Union Medical College Hospital from Nov 2017 to Aug 2021 was retrospectively analyzed.Results:Among the 13 patients, 7 patients had bilateral lesions. 18 tumors were identified by contrast enhanced ultrasound, which showed rich blood supply, with marked enhancement in 13 tumors and moderate enhancement in 5 tumors. The origins of the arterial supply for tumors were identified by contrast enhanced ultrasound. Time-intensity curve analysis showed that the tumors had enhancement characteristics of fast wash in and slow wash out. The mean contrast wash in time was (3.33±1.40) s, the mean peak intensity was (10.41±1.74) dB, and the mean wash out time was (56.47±22.28) s. A total of 13 cases underwent successful surgical removal. Five cases of external carotid artery ligation and 2 cases of internal carotid artery reconstruction were performed during surgery. Postoperative transient neurological injury occurred in 5 cases. There were no cases of cerebral infarction or death in the perioperative period. Mean postoperative follow-up was 14.31 months. Five cases of neurological injury had satisfactory recovery and no other adverse events occurred.Conclusions:Contrast enhanced ultrasound is an effective method of preoperative imaging assessment for CBT, which helps the surgical planning and preoperative preparation.
