大動脈末梢血管の局所解剖とアクセスの解剖

抄録

Understanding the normal anatomy, common variants, and important anomalies of aortic arch, abdominal branches of aorta, and iliac arteries is a prerequisite for safe, efficient procedure of angiography as well as interventional radiology. The number of great vessels that arise from aortic arch may be as few as two or as many as six. The left anterior oblique position is typically used to image the aortic arch. The branches of abdominal aorta may be divided into four groups : ventral, lateral, dorsal and terminal, while the dorsal branches supply the body wall. The terminal branches supply the pelvis and lower limbs. The femoral artery begins behind the inguinal ligament, midway between the anterior superior iliac spine and symphysis pubis, and passes down the front and medial side of thigh, where it passes through an opening in adductor magnus to become popliteal. The first 3 or 4 cm of the femoral artery are clinically called "common femoral artery". The common femoral artery is enclosed, with the femoral veins, in the femoral sheath. Understanding the anatomy of common femoral artery is very important for safe, efficient interventional procedures.
