Henoch The aim of the study was to evaluate the efficacy of preoperative embolization in the management of carotid body tumours. Of the 15 patients admitted to the Department of Vascular Surgery (General Surgery Unit II), Christian Medical College, Vellore, from January 1st 2002 to December 31st 2006 for management of carotid body tumours, 4 patients underwent preoperative embolization and were grouped together. Of the remaining 9 patients who underwent surgical excision, there were 5 with comparable tumour size and these were grouped together into the control group. Surgical outcome of both the groups were compared in terms of operating time, intraoperative blood loss, nerve injury, postoperative morbidity and mortality. There was statistically significant reduction in blood loss and duration of surgery in patients who underwent preoperative embolization. In conclusion, the preoperative embolization is effective in the management of Shamblin type III carotid body tumours.
