Is A Popliteal Aneurysm An Emergency?

Popliteal artery aneurysms, although rare, may put the affected limb at risk. Any symptomatic aneurysm, or one larger than 2 cm, should be considered for repair as above. Endovascular repair has been shown to decrease the length of stay and wound complications; however, its durability is inferior.

How serious is an aneurysm in the leg?

Aortic aneurysms can cause serious complications because they can burst or rupture. Peripheral aneurysms do not rupture as often as aortic aneurysms, although they can do so. However, peripheral aneurysms more commonly can form clots that may block blood flow to your limbs or brain.

How do you fix a popliteal aneurysm?

Popliteal aneurysms can be treated by two methods: open surgical repair, in which a bypass is created around the aneurysm for improving the flow of blood; or endovascular popliteal aneurysm repair, whereby a stent-graft (a tube made of fabric with a metal mesh) is inserted into the area of the aneurysm to support the …

What size popliteal aneurysm requires surgery?

PAAs are the most common peripheral aneurysms with a reported incidence of 0.1–3%. In asymptomatic patients, to prevent potential complications, the reported indications to PAA repair are size >20 mm, high-grade thrombus and poor run-off vessels. PAA symptoms represent an absolute indication to repair.

The predominant inflow and outflow vessels were popliteal artery segment I (45%) and III (65%), respectively.

Can aneurysms go away on their own?

Aneurysms develop over a lifetime,” he says. “Another is that an aneurysm can disappear or heal itself. This is very rare and only happens in aneurysms that are considered benign because the flow of blood is so slow it eventually forms a clot and seals off the bulge.”

What happens if the popliteal artery is blocked?

Long-term pressure on the popliteal artery can cause the artery to narrow (stenosis), causing pain and cramping with just slight activity, such as walking. In severe cases or when undiagnosed, the nerves and muscles in the leg can become damaged. Blood clots may occur in the lower leg (deep vein thrombosis).

Why is popliteal artery more prone to aneurysm?

Why the popliteal artery is more susceptible than other peripheral muscular arteries is unknown. An important factor may be differences in arterial wall composition as compared with other peripheral muscular arteries, which in turn affect wall properties.

What arteries are behind the knee?

The muscle and tendons near the knee are positioned so that they compress the popliteal artery – the main artery that runs through and behind the knee.
