Femoral Artery (Full)

arteria femoralis

The femoral artery is the main arterial supply to the lower limb, accessible at the femoral triangle for vascular access (cardiac catheterisation, EVAR, TAVI). The femoral pulse at the mid-inguinal point is the primary peripheral pulse assessment landmark. Femoral artery aneurysms are the second most common peripheral aneurysm (after popliteal), occurring in 3% of patients with abdominal aortic aneurysm.

Clinical Notes

Femoral artery access for cardiac catheterisation uses the Seldinger technique at the common femoral artery (above the bifurcation into superficial and deep femoral). Complications include haematoma, pseudoaneurysm (treated with ultrasound-guided thrombin injection), arteriovenous fistula, and retroperitoneal haemorrhage from high puncture above the inguinal ligament.

Pathology

Common Injuries & Conditions

Femoral Pseudoaneurysm

Post-catheterisation false aneurysm from incomplete femoral artery puncture site closure managed with ultrasound-guided thrombin injection or surgical repair.
