Lateral Sacral Artery
摘要
The lateral sacral arteries are muscular, mediumsized arteries that fully develop from gestational month 6 onward. These arteries are posterior branches of the internal iliac artery, and they supply the sacrum and surrounding structures. Their branches anastomose with branches of the median sacral artery and the superficial branch of the superior gluteal artery. The lateral sacral arteries have variable origins, branches, and course.
