The authors were the first ones who obtained the established collateral vascular anatomy after external carotid artery embolization and ligation with angiography, vascular transparent specimen filled with ink, microvessel casting and scanning electronic microscope. The results indicated that the rich collateral circulation would be established after external carotid artery ligation. Ligation itself could not cut off blood supply to lesion area. Embolization, in turn, can effectively obstruct blood supply by reducing collateral branches. So we suggest that it is better to use external carotid embolization rather than external carotid ligation for those oral maxillofacial lesions with rich blood supply.
作者是首批通过血管造影、充满墨水的血管透明标本、微血管铸型和扫描电子显微镜获得颈外动脉栓塞和结扎后已确定的侧支血管解剖结构的人。结果表明,颈外动脉结扎后会建立丰富的侧支循环。结扎本身并不能切断病变区域的血液供应。相反,栓塞可通过减少侧支分支有效阻碍血液供应。因此,我们建议对于那些血供丰富的口腔颌面部病变,最好采用颈外动脉栓塞而非颈外动脉结扎。
