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 moreSee 1 more doctor answer
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
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
No: Popliteal aneurysms are usually asymptomatic until they become very large (>3 CM in diameter). Symptoms at that stage may be soreness behind the knee, swelling of foot or calf, or numbness/tingling of the foot, along with an easily palpable pulse behind the knee. Popliteal aneurysms are treated once they are >2cm due to the risk of clotting not rupture. ...Read moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
