Autologous external jugular vein grafting to reconstruct segmental common carotid-internal carotid artery:one case report

1病例报告患者,男,21岁,因＂右颈部缓慢生长无痛性包块3年,进行性头昏5个月＂于2014年3月入院。入院体检发现右侧颈部中上份搏动性包块,大小约4cm×4cm,包块可以左右推移不能上下方向推移,CT增强扫描显示包块明显强化,包裹颈动脉分叉,与动脉无明显解剖间隙（图1a）。术前诊断为颈动脉体瘤,Shamblin Ⅲ型。

We reported a case of carotid body tumor（Shamblin classification,type Ⅲ）patient on whom the tumor was tightly adhered to the carotid bifurcation and the carotid artery broke during the surgery,then autologous external jugular vein was employed to reconstruct the segmental defect of common-internal carotid artery after the tumor and involved common-internal carotid artery was resected.The patient felt no complaint during the twoyear follow-up.Duplex scan demonstrated the patency of transplanted external jugular vein was a good graft without formation of aneurysm.At the time of 2 years after surgery,the transplanted vein arterialized without obvious stricture.This case implies that the external jugular vein grafting is a candidate for reconstruction of segmental carotid artery.
