经眼上静脉入路行海绵窦栓塞的应用解剖学

Applied anatomy of cavernous sinus embolism through superior ophthalmic vein

目的：为经眼上静脉入路行海绵窦栓塞术，治疗颈动脉海绵窦瘘提供解剖学依据。方法：成人头部标本２４个，解剖观测眼上静脉及其眶外属支的形态、长度及外径等。结果：①眼上静脉由眶上静脉支和内眦静脉交通支组成。眶上静脉支穿经眶上孔处外径为１．３ｍｍ。内眦静脉外径为１．４ｍｍ，距内眦６～８ｍｍ，其交通支外径为１．４ｍｍ；②眼上静脉在眶腔内分为三段，外径平均达２．１～２．５ｍｍ。结论：经眼上静脉眶外属支入路具有可行性。

Objective:To provide anatomy data for treatment of carotidcavernous sinus fistulas by means of cavernous sinus embolism through superior ophthalmic vein. Methods:Morphology,length and outer diameters of superior ophthalmic vein and its branches of external orbital were studied and measured on 24 adult head specimens.Results:Superior ophthalmic vein was consisted of supraorbital vein and communicating branch of angula vein.The mean outer diameter of supraorbital vein at supraorbital foramen,the angular vein and its communicating branches were 1.3 mm、1.4 mm and 1.4 mm separately.Superior ophthalmic vein was divided into three parts in orbital cavity,and the mean outer diameter was 2.1～2.5 mm.Conclusions:It is possible to perform cavernous sinus embolism through external orbital branch of superior ophthalmic vein.
