解剖和观察了111具成年尸体(男76,女35)的第四腰动脉.1.第四动脉在椎间孔前方分为腹侧支和背侧支.2.腹侧支通常在腰方肌的后方分为前支和后支.前支向外穿过腹横肌及腹内斜肌至腹壁外侧部;后支向后在髂嵴上缘伴随臀上皮神经,穿过腰背筋膜入臀部3.背侧支经骨纤维孔向后分为内侧支和外侧支.内侧(下)支与腰4神经的后内侧支伴行,通过骨纤维管行向后内入多裂肌.外侧支与腰4神经后外侧支伴行向后外入骶棘肌.

The fourth lumbar artery was dissected and observed in 111 adult cadavers (male 76, female 35) .1 The fourth artery was divided into ventral and dorsal branches in front of the foramen. Rear of the muscle is divided into anterior branch and posterior branch.The anterior branch through the transverse abdominal muscle and abdominal oblique to the lateral part of the abdominal wall; posterior branch of the iliac crest along the upper edge of the gluteal nerve, through the back fascia into Hip 3. The dorsal branch is divided into the medial branch and the lateral branch by the bone fiber hole.The medial (inferior) branch and the posterior medial branch of the lumbar 4 nerve are followed by the medial multifidus muscle Branch and lumbar 4 nerves posterior lateral branch accompanying sacral spine muscle.
