Abstract:
OBJECTIVE:To analyze clinical features, surgical treatment and outcomes of neurilemmoma and carotid body tumors in bifurcation of carotid artery.
METHODS:The clinical data of 17 patients with neurilemmomas and 76 patients with carotid body tumors at the bifurcation of carotid artery, who were surgically treated in Zhongshan Hospital of Fudan University from March 2012 to November 2016, were retrospectively analyzed. The clinicopathological characteristics, surgical procedures and outcomes were compared between two groups.
RESULTS:No difference of preoperative clinical demographic data was found between two groups. Operation time of the neurilemmoma group was significantly shorter than that of the carotid body tumor group[(93.9±30.8) min vs. (159.3±52.9) min, <0.01]. The neurilemmoma group had lower volume of intra-operative blood loss[(110±96) mL vs. (356±239) mL, <0.01] and lower rate of external carotid artery resection (11.8% vs. 68.4%, <0.01) than the carotid body tumor group. In the neurilemmoma group, 17 tumors were completely resected and no malignant disease was found. In the carotid body tumor group, 76 patients underwent complete surgical resection for the tumor, of which 5 (6.6%) were malignant. Tumor size of the neurilemmoma group was larger than that of the carotid body tumor group[(4.5±1.4) cm vs. (3.1±1.0) cm, <0.01]. There was no significant difference in the incidence of peri-operative complications and length of hospital stay between two groups (>0.05).
CONCLUSIONS:The clinical manifestations of neurilemmoma and carotid body tumors at carotid artery bifurcation are similar. The carotid body tumor group has a longer operating time, larger intra-operative blood loss, higher external carotid resection rate and relative higher incidence of malignancy. More cautions should be given when carotid body tumors at carotid artery bifurcation are treated.
