The Femoral Triangle and Vasculature Flashcards
What form the borders?
Superior - inguinal ligament
Lateral - medial border of sartorius muscle
Medial - lateral border of adductor longus
Anterior roof - fascia lata
Posterior base - pectineus and iliopsoas muscles
Where is the femoral triangle found?
Anterior thigh
Contents of the femoral triangle? Lateral to medial?
Femoral nerve Femoral artery Femoral vein Deep lymph nodes (NAVEL)
Where can you find the femoral pulse?
Halfway between the pubic symphysis and ASIS
Tell me about a femoral hernia
Part of the bowel pushes into to be femoral canal, underneath the inguinal ligament
Manifests clinically as a lump or bulge in the femoral triangle
Requires surgery
Where does the inguinal ligament run to and from?
Anterior superior iliac spine to the pubis tubercle
What is the main artery of the lower limb and when does it become called this vessel?
Femoral artery
External iliac artery becomes this vessel when it crosses under the inguinal ligament and enters the femoral triangle.
Branches of the profunda femoris artery?
Perforating branches
Lateral femoral circumflex artery
Medial femoral circumflex artery
Path of the femoral artery?
Enters femoral triangle. The down the adductor canal. This ends at the adductor hiatus. Artery travels through the opening and enters the posterior compartment of the thigh, proximal to knee. Now becomes the popliteal artery.
What can the femoral artery be used for clinically?
Coronary angiography
Draw blood for arterial blood gases
What is the path of the tube in a coronary angiography?
Femoral artery ➡️ external iliac artery ➡️ common iliac artery ➡️ aorta ➡️ coronary vessels
Path of the obturator artery?
Arises from the internal iliac artery in the pelvic region. Descends via obturator canal to enter medial thigh. Bifurcated into anterior branch and posterior branch.
Path of the gluteal arteries?
Arise from the internal iliac artery, entering the gluteal region via the greater sciatic foramen.
Superior gluteal leaves foramen above piriformis
Inferior gluteal below the piriformis
What does the popliteal artery bifurcate into?
The anterior and posterior tibial arteries
Path of posterior tibial artery?
Along the surface of the deep muscles. Accompanies tibial nerve in entering the sole of the foot via the tarsal tunnel.
