The disposition of keeping carotid artery continuity in treatment of carotid body tumor / 医学研究生学报

ABSTRACT

Objective Carotid body tumor is closely related to carotid artery .How to deal with carotid artery is the guaranty of successful surgery .The aim of this study was to summary the experience of keeping carotid artery continuity in the treatment of 15 carotid body tumor cases . Methods Clinical data of 15 cases with 17 carotid body tumors , in which 2 patients had bilateral tumors , were collected.The 17 carotid body tumors were classified as Shamblin I (6 cases),Ⅱ(6 cases) andⅢ(5 cases).Fifteen tumors were dissected simplely.Among these 15 tumors, three of Shamblin Ⅱand two of Shamblin Ⅲunderwent repair of the break of carotid artery.The rest two of Shamblin Ⅲunderwent tumor and external carotid artery excision and internal carotid artery repairment .Matas pressing test of carotid artery or carotid artery balloon occlusion test was not performed in any patient . Results All 17 tumors were successfully excised .None of the 17 tumors underwent anastomosis or reconstruction of internal carotid artery or arteria carotis com -mun.The continuity of carotid artery or internal carotid artery was kept in all the patients after tumor excision .Hoarseness and bucking induced by the injury of vagus nerve occurred in 13 cases, and bucking recovery in all the cases after 2 years follow up, and only one case remained mild hoarseness .Hypoglossal nerve injury occurred in 4 cases with tongue deviation , and the symptom recovery after 6 months follow up.No one had recurrent by the follow-up period ranging from 1 to 9 years. Conclusion Most carotid body tumors could be completely resected by tumor dissection method with the accurate treatment , thereby the continuity of carotid artery could be kept.The Matas pressing test of carotid artery or carotid artery balloon occlusion test is not necessarily to every patient .
