At the upper border of the adductor brevis it gives off two branches: [1]. The ascending branch; The descending branch descends beneath the adductor brevis, to supply it and the adductor magnus; the continuation of the vessel passes backward and divides into superficial, deep, and acetabular branches.
The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall.
It is the smallest branch of the lateral circumflex femoral artery and passes lateralward over the vastus intermedius, pierces the vastus lateralis, and winds around the femur, just below the greater trochanter, anastomosing on the back of the thigh with the medial femoral circumflex artery, the inferior gluteal artery, and the perforating ...
The ascending branch of medial circumflex femoral artery is a small artery in the thigh. It branches of the medial circumflex femoral artery and is distributed to the adductor muscles of the hip. It anastomoses with the obturator artery. It also serves as an important blood supply to the head of the femur.
The deep circumflex iliac artery arises from the lateral aspect of the external iliac artery nearly opposite the origin of the inferior epigastric artery.. It ascends obliquely and laterally, posterior to the inguinal ligament, contained in a fibrous sheath formed by the junction of the transversalis fascia and iliac fascia.
From here, wires and catheters can be directed anywhere in the arterial system for intervention or diagnostics, including the heart, brain, kidneys, arms and legs. The direction of the needle in the femoral artery can be against blood flow (retro-grade), for intervention and diagnostic towards the heart and opposite leg, or with the flow (ante ...
Inferior or distal to the origin of the descending genicular artery are two superior genicular arteries: Medial superior genicular artery; Lateral superior genicular artery; The middle genicular artery is a small branch of the popliteal artery that originates inferior or distal to both the superior genicular arteries as well as the sural arteries.
The second perforating artery (a. perforans secunda), larger than the first, pierces the tendons of the adductores brevis and magnus, and divides into ascending and descending branches, which supply the posterior femoral muscles, anastomosing with the first and third perforating. The second artery frequently arises in common with the first.
