A rationale is presented for extra-anatomic carotid cross-over bypass to maintain or restore blood flow to the internal carotid artery distal to sites of disruption and ligation of a common carotid artery. Anatomic evidence indicates that the attachment of the carotid sheath to the hyoid bone is a barrier to spread of infection cephalad to that level. A patient with infected and disrupted right common carotid artery associated with an esophageal fistula was treated by double ligation of the artery. Contralateral hemiplegia 48 hours later forced consideration of cerebral revascularization. Left carotid angiography demonstrated patent cerebral vessels on the right, with retrograde filling of the right internal carotid artery to the bifurcation. These findings were interpreted as consistent with technical feasibility of external carotid to external carotid cross-over vein bypass in a suprahyoid location, avoiding reconstruction in an infected area and resulting in prompt recovery of function.
提出了进行解剖外颈动脉交叉搭桥术以维持或恢复颈总动脉中断和结扎部位远端颈内动脉血流的理论依据。解剖学证据表明，颈动脉鞘与舌骨的附着是感染向该水平以上扩散的屏障。一名患有感染性右颈总动脉破裂并伴有食管瘘的患者接受了动脉双重结扎治疗。48小时后对侧偏瘫促使考虑进行脑血运重建。左颈动脉血管造影显示右侧脑血管通畅，右颈内动脉逆行充盈至分叉处。这些发现被解释为在舌骨上位置进行颈外动脉到颈外动脉交叉静脉搭桥术在技术上可行，避免在感染区域进行重建并导致功能迅速恢复。
