Abstract：Carotid body tumors are a subgroup of neuroendocrine tumors,originating from paraganglia and also known as paragangliomas.They are rare in clinic.Complete resection of the tumor is the main surgical method.Due to the particular location of the tumor,the internal carotid artery and surrounding vital nerves may be injured during the operation,and serious complications such as cerebral ischemia and hemiplegia may occur postoperatively.This paper reports a case of bilateral carotid body tumors.The left tumor was resected in the first-stage surgery,and the right tumor was removed in the second-stage surgery two weeks later.Three days postoperatively,dizziness and blurred vision improved significantly,and the symptoms vanished completely three months postoperatively.Reexamination of head MRA six months after the surgery revealed no tumor recurrence.This indicates that for bilateral carotid body tumors,dealing with the tumor with a lower risk first and then the one with a higher risk can avoid complications such as postoperative baroreflex failure syndrome.Operating under a microscope during the surgery can reduce damage to blood vessels and nerves.If the tumor envelopes or invades the surrounding nerves to a small extent,the postoperative symptom improvement is extremely obvious.
