颈总动脉间断阻断下颈动脉体瘤切除术的疗效观察

对7例颈动脉体瘤患者在局麻下行颈总动脉阻断脑缺血试验。全麻下采用间断阻断颈总动脉下的颈动脉体瘤切除治疗术．部分患者术前行DSA栓塞，观察并发症发生情况及治疗效果。所有病例均未行内转流术。术中阻断颈动脉2．4次，每次阻断时间最长达28min，平均22min。术后出现神经并发症3例。未行供血动脉栓塞者平均失血1100ml，行栓塞者平均失血480ml。术中间断性动脉阻断试验对于判断是否需行内转流术、方便手术操作、减少失血及神经并发症有重要帮助。

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 1100ml, cases with embolization was 480ml. 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.
