NAVL
Femoral Nerve
Femoral Artery
Femoral Vein
Femoral Lymphatic canal
Good for femoral pulse and is the site for the insertion of catheter and angiography
Femoral sheath
What does it surround
Continuation of…
Surrounds the femoral artery, vein, and canal and NOT the femoral nerve
Is a continuation of the transversalis fascia
Femoral Canal
Contains what
Contains lymph vessels that drain the lower limb that drain to external iliac nodes in abdomen. Open superiority to the abdomen and the opening is called the femoral ring
Femoral hernia
Femoral ring is the point of potential weakness in the abdominal wall: a loop of bowel can protrude into the femoral canal and become strangulated (Females)
Inguinal Hernia
Differentiated from femoral hernias by the location of the neck of the hernia. Inguinal herinia neck is located above the inguinal ligament
Arterial Supply
Flow down the leg and boundary of each
External iliac–>inguinal ligament–>Femoral Artery, goes ant first and then post bc of medial rotation @ development–>adductor hiatus–>popliteal artery
The popliteal artery. Divides into what
Anterior and posterior tibial arteries
Which tibial artery is the main blood supply to the foot?
Posterior tibial artery
Where are the anastomoses in the lower body?
Which joints
Cruciate anastomoses at the hip and genicular anastomoses at the hip
Describe the passage of the femoral artery through the leg
1st, passes medial in the anterior thigh and deep to the sartorius in a. Space called the subsartorial canal. 2nd, passes posteriorly though an opening in the adductor magnus muscle called the adductor hiatus. 3rd, once this happens the femoral artery becomes the popliteal artery on the posterior side of the knee
Where is the profunda femoris found and what does it supply
Largest branch of the femoral artery, arises posteriory in the femoral triangle, and passes between the pectineus and adductor longus branches
Medial femoral circumflex supplies and where it is located
Passes directly posteriorly between pectineus and iliopsoas and provides the majority of the blood supply for the head of the femur
Lateral femoral circumflex passage and supply
Passes laterally, deep to rectus femoris. Supplies lateral side of thigh, neck of femur. Has descending branch that is part of the genicular anastomoses at the knee joint
Ischemic necrosis
Falling in the elderly can damage the medial circumflex artery due to the fracturing of the neck of the femur. This head receives blood supply from the medial femoral circumflex artery and the obturator. If the obturator blood supply is inefficient the head of the femur can necrosis and require hip replacement.
Perforating arteries of the femoral artery.
Provide blood supply to the posterior compartment of the thigh. They erforate the adductor magnus muscle deep adjacent to the femur.
Composition of the cruciate anastomoses Superior Medial Lateral Inferior
Superior: medial femoral circumflex (from internal iliac)
Medial: medial femoral circumflex (profunda femoris)
Lateral: lateral femoral circumflex (profunda femoris)
Inferior: first perforating artery (profunda femoris)
Femoral artery ligation
Can be lighted due to the cruciate anastomoses which will maintain blood supply to the hip joint
