Abstract:
The internal iliac artery and its chief branches were observed on both sides of 160 Chinese cadavers. The origin of the internal iliac artery was mostly on a level with the 5th lumbar vertebra and lumbo-sacral intervertebral disc (80.94%). In most instances,the right side was higher than that of the left, and the male higher than that of the fe-male.According to the origin of its three main branches--superior gluteal, inferior glutealand internal pudendal arteries--the types of branching of the internal iliac artery mightbe classified into five types and ten subtypes. The prevailing type was type Ⅰ (55.94%),in which the internal iliac artery gave off first the superior gluteal artery, then the inferiorgluteal-pudendal trunk. Many of the superior gluteal artery (79.06%) perforated the sacral nervous plexusbetween the lumbo-sacral trunk and first sacral nerve. In 94.69% of the pudendal artery and 51.6% of the inferior gluteal artery left the pelvis by passing in front of the sacralplexus.The ilio-lumbar artery varied from 1--3 in number, most of them (65.62%) weresingle. This artery might spring from the superior gluteal artery. The obturator arteryusually originated from the internal iliac artery (80%), occasionally from the external iliac artery (17.19%), rarely from both (2.81%). The middle rectal artery commonlysprang from the internal pudendal artery. The double uterine artery was found in 11cases, the additional artery always sprang from the umbilical portion of the internal iliac artery.
