子宫下段剖宫产以其术时损伤小、术后愈合快、合并症少等优点已在临床广泛应用。以往子宫下段剖宫产切开子宫的方式有纵横两种,横切口的优点是切口与肌纤维走向一致,术时切断肌纤维较少,术后愈合好;缺点是因两侧有子宫动静脉,切口不能过分伸延。纵切口则易向下撕裂损伤宫颈及膀胱。临床遇有身材瘦小、子宫畸形所致子宫下段横轴较短时,或巨大胎儿所致相对性子宫下段横轴较短时,无论纵横切口都有向两侧或向下撕裂的危险。我们在临床实践中总结出纵横互补式切开子宫法恰好弥补了上述不足,具有既能扩大切口利于胎儿娩出又可避免切口撕裂,并且操作简便安全易被临床医师掌握的优点,现介绍如下。
Lower uterine cesarean section with its surgery when the injury is small, fast healing, fewer complications and other advantages have been widely used in clinical practice. In the past the lower uterine segment of the uterus cesarean section has two kinds of vertical and horizontal ways, the advantages of transverse incision is consistent with the muscle fibers to cut off less muscle fibers during surgery, the healing is good; the disadvantage is due to both sides of the uterine artery and vein, incision Can not be over-stretched. Longitudinal incision is easy to tear down the cervix and bladder damage. Clinical case of thin, uterine malformations due to lower horizontal section of the lower abdomen or shorter, or fetal macrosomia caused by lower relative length of the lower abdomen shorter, both vertical and horizontal incision there is the risk of tearing to both sides or down. In clinical practice, we conclude that the vertical and horizontal complementary incision uterus just make up for the above shortcomings, not only can expand the incision to facilitate the delivery of the fetus but also to avoid incision tear, and easy to operate safe and easy to grasp the advantages of clinicians are presented below .
