肠套叠为一段肠管套入其远端的肠腔内,使该段肠壁重叠并拥塞于肠腔引起肠道梗阻。肠套叠由鞘部和套入部组成,鞘部为外层,套入部有两层,故肠套叠由三层肠壁构成,多为近侧套入远侧肠管,偶有逆行套叠者。以前常以钡灌肠或胃肠造影作为首选检查方法,但有时诊断较困难。近年来随着CT技术 Intussusception for a set of intestines into the distal end of the intestine, the segment of the intestinal wall overlap and congestion in the intestine caused intestinal obstruction. The intussusception consists of a sheath and a sheath, the sheath is the outer layer, and the sheath has two layers. Therefore, the intussusception consists of three layers of intestinal wall, mostly proximal sheathing, distal retrograde . Barium enema or gastrointestinal angiography is often used as the preferred method of examination, but sometimes more difficult to diagnose. In recent years with the CT technology
