Can prednisone cause popliteal aneurysm?

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

Prednisone (Definition)

Prednisone is a synthetic cortisone. The body makes cortisone, a natural hormone made in adrenal glands. The body converts it to Hydrocortisone to become active. 25 mg of cortisone has about same effect as 5 mgm prednisone. The average person would produce 3-6 mg of pred daily. So why use a substitute? The synthetic has more anti-inflammatory effect; but has less effect ...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?

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

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

How often should you have your popliteal aneurysm checked?

Annually: Once a year by ultrasound should be enough. You don't have to be concerned about treatment until it reaches a diameter of around 2cm. We don't worry about rupture. It is the formation of a blood clot and blockage of flow to the foot which is more likely to occur. These can be fixed surgically by replacing the short segment of artery or stenting. ...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

How does a popliteal aneurysm affect sleep?

How does a popliteal aneurysm affect sleep?

Two possibilities...: It could be large enough that the person is aware of a pulsing sensation that keeps him awake. Alternatively, if the aneurysm is thrombosed (clotted), there could be compromised blood flow to the foot which causes pain at night because the leg is elevated (the blood flow is so limited that the person needs the benefit of gravity to get blood to the foot). ...Read more
