Abstract
Thirty-two patients with 37 carotid body tumours, seen in the Vascular Unit at the Royal Victoria Infirmary, Newcastle upon Tyne between 1956 and 1985 are reviewed. Twenty-six of the tumours were treated by surgical excision. There were no peri- or postoperative deaths, but one patient developed a permanent hemiplegia following surgery (3.8 per cent); cranial nerve palsy occurred in five patients (19.2 per cent). There were no malignant tumours although in one patient, histology of the resected specimen showed the presence of local lymph node invasion (3.8 per cent). In the 7 patients who did not undergo surgery, 3 have been lost to follow-up; the remainder have not shown any significant increase in the size of the tumour. One patient was treated by radiotherapy. It is concluded that surgical excision is the treatment of choice, though observation may be preferred for the older patient with a symptomless, slow-growing tumour. To help reduce the risk of hemiplegia (the most serious complication of surgery) a meticulous surgical technique is necessary and heparin, intraluminal shunting and facilities for arterial repair and grafting must be at hand.
