A peripheral aneurysm is an aneurysm that occurs in arteries other than the aorta. These most commonly occur in the popliteal artery, which runs down the back of the lower thigh and knee, but can also occur in the femoral artery (groin), the carotid artery (neck) or the arteries in the arms. A special type of peripheral aneurysm that forms in the arteries feeding the kidneys or the bowel is called a visceral aneurysm. Many of these can now be treated with minimally invasive endovascular embolisation.
While peripheral aneurysms do not rupture as often as aortic aneurysms, they are more likely to create blood clots that can block the flow of blood to the limbs or brain. Popliteal aneurysms in particular carry a significant risk of clot formation (thrombosis) or embolism to the foot, which can threaten the limb. They are commonly found in patients who also have an AAA.
Treatment
Treatment depends on the size of the aneurysm, the patient’s symptoms and the presence of clot within the sac. Options include open surgical repair (bypassing the aneurysm with a vein or synthetic graft) and endovascular stent-graft repair. The goal is to exclude the aneurysm from the circulation, restore normal blood flow and prevent the risk of clot formation and embolism to the limb.

Treatments Available for Peripheral Aneurysms
Below are some of the treatments we have available for Peripheral Aneurysms. Click on the below to learn more or get in touch with us to request a consultation.
Endovascular Aortic Aneurysm Repair (EVAR/FEVAR/BEVAR)
EVAR, FEVAR and BEVAR are minimally invasive techniques for repairing aortic aneurysms using a stent-graft delivered through small incisions in the groin. They offer shorter hospital stays and faster recovery compared to traditional open surgery.
Endovascular Treatment of Visceral Artery Aneurysms
Minimally invasive endovascular treatment of splenic, renal, hepatic and mesenteric artery aneurysms at Perth Vascular Clinic. Coil embolisation and stent-assisted coil embolisation seal the aneurysm through a small puncture, with faster recovery than open surgery.

Frequently Asked Questions
A peripheral aneurysm is an abnormal bulging of an artery outside the aorta. The most commonly affected arteries are the popliteal artery behind the knee and the femoral artery in the groin. Peripheral aneurysms can cause clotting, limb-threatening ischaemia, or rupture.
