I have a constant ache behind the knee. Could this be popliteal aneurysm?

It is possible: A constant ache behind the knee can be due to many things including a popliteal artery aneurysm. Pain behind the knee is most commonly due to orthopedic problems such as a baker's cyst. An ultrasound can easily diagnose a baker's cyst or a popliteal artery aneurysm. ...Read more

Popliteal Aneurysm (Definition)

Popliteal aneurysm is a swelling of the popliteal artery, which is one of the major arteries of the thigh, running behind the knee. Popliteal aneurysms are a problem because they are prone to rupturing and bleeding, or developing a clot, which then blocks blood flow ...Read more

I have tingling sensation behind my left knee. Does this mean I have a popliteal aneurysm?

I have tingling sensation behind my left knee. Does this mean I have a popliteal aneurysm?

Unlikely: Popliteal artery aneurysms are not typically symptomatic (not painful) until they occlude. We don't worry about these rupturing. We worry mainly about these clotting and blocking circulation to the legs. Tingling would not be associated with a popliteal aneurysm. ...Read more

Might a popliteal aneurysm cause the upper leg to feel like it is pushing into the lower leg with general tightness in the knee and on the sides?

Might a popliteal aneurysm cause the upper leg to feel like it is pushing into the lower leg with general tightness in the knee and on the sides?

Possibly: Popliteal aneurysms are a dangerous condition, as most do not cause symptoms until something catastrophic occurs; typically clots form in the aneurysm & embolize to the lower leg. This leads to emergent surgery & many times even with surgery the leg will be lost to amputation. The best way to diagnose is with ultrasound. Larger ones can be appreciated on leg exam. Sometimes tightness occurs. ...Read more

Constant pain and dull ache on outer left calf and behind knee(popliteal area). Also, getting spasm on inner calf while at rest. Rest not helping?

Constant pain and dull ache on outer left calf and behind knee(popliteal area). Also, getting spasm on inner calf while at rest. Rest not helping?

Probably sprain, or: could be something called a Baker's cyst. An ultrasound would help figure that out. Try ice to area 15 min/hr and take ibuprofen and continue to rest. This should help within a week or so if it is a sprain. ...Read more

If I have a popliteal aneurysm, will I have other aneurysms in the future?

Possibly: The popliteal artery is the third most common location for a aneurysm. These frequently occur in both legs. Patients who have one aneurysm are more likely to develop others in the aorta and femoral ( groin ) and iliac arteries. These patients are followed closely for early detection. ...Read more

I have a large left popliteal aneurysm. When should I consider surgery?

I have a large left popliteal aneurysm. When should I consider surgery?

Soon: If you have a large aneurysm in the popliteal artery, it is at risk for thrombosing (clogging off) or embolizing (tossing debris), and puts you at risk for losing your leg. Larger aneurysms can also compress local structures and cause blood clots in your vein, or pain from pressure on the nerve. It is also possible for the aneurysm to rupture, but this is more common in aortic aneurysm. ...Read more

What are the consequences of an elderly man with a ruptured popliteal aneurysm?

What are the consequences of an elderly man with a ruptured popliteal aneurysm?

A serious problem: Popliteal aneurysms very rarely rupture, but instead they more commonly thrombose. When this occurs small pieces of clot shower downstream into all of the small artery branches below the knee. This is a vascular surgery emergency. Over half of patients who suffer thrombosis of a popliteal artery aneurysm will require amputation, below or often above the knee. ...Read more

Can prednisone cause popliteal aneurysm?

No: Prednisone is not likely to cause a popliteal aneurysm. The cause is thought to be an inflammatory process. If you have a popliteal aneurysm >2cm, you should consider treatment to avoid it from clotting off. These do not rupture. More importantly, almost 50% of people with popliteal aneurysms have an abdominal aortic aneurysm. Ultrasound screening is recommended. ...Read more

What does it mean to have a popliteal aneurysm rupture?

What does it mean to have a popliteal aneurysm rupture?

Not good...see below: An aneurysm is an dilitation of a blood vessel. This is the result of weakening in the wall of the artery. The weakened wall can rupture, and bleeding into the tissues around the knee occurs, causing tremendous pain and swelling. The blood outside the artery can then impinge on flow to the lower leg and foot, causing ischemia. In all, very bad, and one of the reasons to fix aneurysms electively. ...Read more
