[Resection of carotid body tumor under interrupted block of common carotid artery].
7 patients with carotid body tumor (CBT) were evaluated by DSA preoperatively. Carotid artery (CA) blocking test was carried out under local anesthesia before operation. With CA blocked temporarily, tumors were resected under general anesthesia after the test was normal. Meanwhile some cases underwent restoration with CA repair, end-to-end anastomosis or artificial vascular grafting. No case underwent internal bypass. CA was blocked 2 to 4 times in operation. The average blocking time of CA was 22 minutes and the longest blocking time of that reached 28 minutes. The average blood loss of cases without embolization preoperatively was 1100 ml, cases with embolization was 480 ml. 3 cases had nerve complications. DSA is of important value in the diagnosis and treatments of CBT. Temporary blocking artery method can help to judge when to use internal bypass, make operation easy, decrease blood loss and nerve complications.
