回结肠肠段血管配布的应用解剖及其临床意义

Applied Anatomy of the Vascularity in the Ileocolic Region and Its Clinical Significance

为了解回结肠肠段动脉、静脉的配布特点及其相互关系，观察５０具成人和儿童尸体的回盲部、升结肠、横结肠的动脉、静脉配布及其在供应肠段的边缘吻合情况。结果示回结肠肠段的静脉配布较动脉恒定；动脉配布共分７个类型；边缘动脉未见吻合中断，但右结肠静脉与中结肠静脉间有３例吻合完全中断。上述解剖特点可指导临床回结肠代食管的手术操作，以防止或减少术后并发症的发生。

To understand the characteristics of the patterns of arteries and veins distributed over the ileocolic segment,50 cadavers were studied by gross anatomy.The arteries,veins and their paracolic anastomoses distributed over ileocecal region,ascending colon and transverse colon were observed.The results showed that the distribution pattern of venous vessel was far more constant than that of artery,that the arrangements of artery in the ileocolic segment were classified into 7 types,and there were no interruption of paracolic anastomoses between arteries. But in 3 specimens the paracolic anastemoses between the right colic vein and the middle colic vein were completely interrupted.These findings may be useful in guiding clinical practice and preventing postoperative complications in ileocolic replacement of esophagus.
