目的 观测大网膜的形态及血管分布，探讨大网膜的设计剪裁，为临床提供可靠的解剖学资料。 方法 选用12例防腐固定处理的成人尸体,3例成人新鲜尸体。分别巨微解剖观测大网膜的形态及血管分布、进行明胶-氧化铅血管造影及三维重建。 结果 大网膜的长度为(24.7±6.9)cm,宽度为(28.3±2.8)cm，分为薄、中、厚三型，薄型占33.3％，中型占46.7％，厚型占20.0％。大网膜的血供来源于胃网膜左、右动脉沿胃大弯连接而构成胃网膜血管弓，从胃网膜血管弓向大网膜发出血管分支。大网膜的主要动脉有4条：①大网膜右动脉：起始处外径为（1.0±0.4）nm。②大网膜中动脉：起始处外径为(0.7±0.3)mm。③大网膜左动脉：起始处外径为(1.2±0.4)mm。④大网膜副动脉：起始处外径为(0.5±0.l)mm。 结论 根据大网膜前、后弓血管的解剖特点、大网膜中动脉分叉位置的高低及与延长方法，将大网膜分为5种不同的类型。在临床裁剪使用大网膜时，应根据5型的不同特点做不同的裁剪。

Objective To observe the shape, size, position and vessels of greater omentum. To explore the design of greater omentum and clarify its clinical significance. Methods Three fresh and 12 formalin-fixed cadaveres were dissected. All of them had no damage nor injury. 1. Macro-micro-dissection: The shape, size and position of greater omentum were observed. The vessels of the greater omentum were studied.2. Lead oxide-gelatin injection technique and three-dimensional reconstruction.Results The length of greater omentum was(24.7±6.9)cm,the width was(28.3+2.8)cm. It could be divided into 3 types: thin type,middle type and thick type, the occurrence rate was 33.3％, 46.7％ and 20.0％ respectively. The blood supply of greater omentum mainly came from the gastroepiploic arch composed of the left gastroepiploic artery and the right gastroepiploic artery. There were 4 main arteries of the greater omentum: ①The right epiploic artery: The external diameter at origination was (1.0±0.4)mm. ② The middle epiploic artery: The external diameter at origination was(0.7 + 0.3)mm. ③The left epiploic artery:The external diameter at origination was (1.2±0.4)mm. ④ The accessary epiploic artery: The external diameter at origination was (0.5 ± 0.1)mm.Conclusion According to the characteristic of the anterior arch and posterior arch, the position of the middle epiploic artery divarication and the method of spread, the greater omentum is divided into 5 types. It should be according to the characteristic, when the greater omentum is designed and clipped.
