The lateral sacral arteries anastomose with each other and with the middle sacral. The gluteal artery (P) is a large vessel, which is the continuation of the posterior division. It is destined for the supply of the gluteal region, and lies within the pelvis for a very short distance. Its direction is backwards through the parietal pelvic fascia, and between the lumbo-sacral cord and the anterior primary division of the first sacral nerve, its escape from the pelvis being through the upper compartment of the great sacrosciatic foramen. The branches of the artery within the pelvis are unimportant. For the extrapelvic course and distribution of the vessel, see P-430. The branches of the internal iliac, with one exception, have to pierce the pelvic fascia. The exception is the obturator artery, which, as stated, passes over the upper border of the parietal pelvic fascia at the obturator canal. Internal Iliac Vein.--This vessel results from the union of branches which correspond, for the most part, with branches of the internal iliac artery. The ilio-lumbar vein, however, is an exception, inasmuch as it is a tributary of the common iliac vein. Moreover, during foetal life the umbilical vein, which corresponds to the hypogastric (subsequently umbilical) artery, passes to the liver after entering the abdomen of the foetus. The internal iliac vein extends from the upper part of the great sciatic notch to the sacroiliac articulation on a level with the pelvic brim, where it joins the external iliac, and so the common iliac vein is formed. In its course it lies behind the corresponding artery. There are no valves in the ve...
