Treatment of femoral artery aneurysm
High-Yield Explanation
Femoral and Popliteal artery aneurysms
Femoral and Popliteal artery aneurysms constitute about 90% of peripheral aneurysms. Femoral 20% and Popliteal 70%.
The majority of these aneurysms are the degenerative type.
More common in men. Popliteal artery aneurysms are almost always seen in men (97%)
More than 50% are bilateral.
Large no. of patients have associated aortic aneurysms.
Like aortic aneurysms, they are silent until critically symptomatic. However, unlike aortic aneurysms, they rarely rupture.
The presenting manifestations are due to peripheral embolization and thrombosis leading to distal limb ischemia.
Peripheral aneurysms rarely may also produce symptoms by compressing the local vein or nerve.
Imaging:
Duplex color ultrasound is inv of choice to confirm the diagnosis of peripheral aneurysms.
Treatment
Indications for treatment include
acute lower limb ischemia, or
transverse diameter greater 2 cm or
presence of mural thrombus.
Treatment consists of
open surgery with prosthetic interposition grafting for femoral aneurysms and saphenous vein grafting for popliteal aneurysms.
endovascular repair with stent grafts
Pseudoaneurysm of the femoral artery due to arterial punctures can be successfully treated using ultrasound-guided compression of the neck of the aneurysm with or without thrombosis of the aneurysm by thrombin injection
