What is a superficial femoral artery occlusion?
Occlusion of a major lower extremity artery is a primary stimulus to the enlargement of pre-existing collateral vessels, and the superficial femoral artery (SFA) is the most common site of lower extremity arterial occlusions (4).
Where is the femoral artery most superficial?
As the femoral artery is relatively superficial within the femoral triangle, the femoral pulse is usually easily palpated. It can be palpated midway between the anterior superior iliac spine and pubic symphysis, just inferior to the inguinal ligament.
Which signs and symptoms are associated with atherosclerosis of the superficial femoral artery?
Atherosclerotic disease of superficial femoral artery is deemed high risk to present with diffuse distribution, frequent calcification, large plaque burden, and high progression rate to total occlusion . Additionally, femoral popliteal segment is exposed to significant flexion, bending, and compression forces.
What is the average length of the superficial femoral artery?
The average common femoral artery is approximately 4 cm in length and lies just anterior to the femoral head. Its length and diameter are quite variable depending on characteristics such as height, weight, sex and ethnicity.
When does superficial femoral artery become popliteal?
The popliteal artery is the direct continuation of the superficial femoral artery, at the point where it exits the adductor canal at the adductor hiatus, and passes into the popliteal fossa as the vessel courses posteriorly behind the knee.
Where is the aortoiliac artery located?
The iliac arteries branch off of the bottom of the aorta, the large artery coming out of the top of the heart. The iliac arteries are peripheral arteries.
Where is femoral artery palpated?
Cover the genitalia with a sheet and slightly abduct the thigh. Press deeply, below the inguinal ligament and about midway between symphysis pubis and anterior superior iliac spine. Use two hands one on top of the other to feel the femoral pulse. Note the adequacy of the pulse volume.
When is disease of the superficial femoral or popliteal artery suspected?
Such non-compressible arteries should be suspected when the ABI is greater than 1.3 or when the lower extremity systolic pressure is more than 20% higher than the brachial systolic pressure.
Where does the fibular artery originate?
posterior tibial artery
The peroneal (fibular) artery arises from the posterior tibial artery. It descends posterior to the fibula in the deep posterior compartment and ends on the lateral surface of the calcaneus as the lateral calcaneal artery. The anterior tibial artery is the first end branch of the popliteal artery.
What is the superficial femoral artery (SFA)?
The superficial femoral artery (SFA) is unique in that it runs the length of the thigh without any significant side branches and is subject to a range of forces that alter the flow dynamics, including extension, flexion, contraction, torsion, and compression.
Where is the femoral artery located in the body?
Within the femoral triangle, the femoral artery is located deep to the: 1 Skin 2 Superficial fascia 3 Superficial inguinal lymph nodes 4 Fascia lata 5 Superficial circumflex iliac vein 6 Femoral branch of the genitofemoral nerve More
What does the profunda femoris artery supply?
The profunda femoris artery supplies the thigh muscles – the superficial femoral artery has no major branches. The anterior tibial artery is the most lateral calf vessel, whereas the posterior tibial artery is the most medial.
Where does the superficial femoral artery give off the descending genicular artery?
The superficial femoral artery gives off the descending genicular artery branch just proximal to the adductor hiatus. The descending genicular artery travels distally and gives off a saphenous branch proximally and musculare branches distally. The superior medial genicular artery arises from the superficial femoral artery more distally.
