Abstract: 目的 探讨翼点入路和眉弓锁孔入路对前交通动脉复合体显露的解剖学区别.方法 选择10个经乳胶灌注后的成人防腐尸头标本,按解剖入路的不同分为翼点入路组与眉弓锁孔入路组,共10例,20侧;每例标本均一侧为翼点入路,一侧为眉弓锁孔入路进行解剖观察.比较两组标本前交通动脉复合体的解剖学情况.结果 眉弓锁孔入路组中,颧突与同侧前床突的距离为(6.23±0.25)cm,角度为(34.08±3.15)°,而翼点入路组中,翼点和同侧前床突距离为(5.03±0.24) cm,角度为(63.49±4.67)°,两组比较具有显著差异(P<0.05);眉弓锁孔入路组在A1段、ACoA段、A2段的完全暴露例数均比翼点入路组少(P<o.05);眉弓锁孔入路组穿支动脉拉破、穿支动脉移位发生率少于翼点入路组[10.00%(1/10) vs60.00% (6/10),0.00% (0/10)vs 50.00% (5/10)](P<0.05).结论 翼点入路具有暴露范围广、操作空间大等优势,而眉弓锁孔入路虽暴露面积小于翼点入路,但其安全性较高,创伤小.
