If benign, simple removal leaving artery CCA and it's branches ECA ICA intact is simple and safe. If malignant neoplasm, surgical resection with interposition graft (saphenous vein) is curative surgery.
We do not utilise embolization for carotid body tumors even preoperatively. I excise the Cervical benign paragangliomas usually without using carotid shunts. High altitude areas ( e.g.Kasmir) have high incidence of paragangliomas, so we operate many CBT patients. In our experience only 10% pts. with large tumors engulfing the internal carotid artery need intraoperative shunts.
Malignant tumors if large usually need intra operative carotid shunts and may need sacrificing the ECA(safe) and internal carotid artery bypass grafting for radical excision of the tumor, as there is little role of radiotherapy or chemotherapy .
Dear Alexandre Campos Moraes Amato ,
It Depends . We use both tecniques .
Generally when the carotid body tumor is small i prefer to treat with surgery .When we have large tumors or they are around the internal carotid artery we try to do embolization before surgery
