It is a type of lower extremity aneurysm.<\/p>\n<p>You might not notice any symptoms. The first symptom may be pain in the lower leg that occurs with walking, called claudication. Other symptoms of a popliteal artery aneurysm include:<\/p>\n<ul>\n<li>Knee pain.<\/li>\n<li>Lower leg pain.<\/li>\n<li>Swelling behind the knee.<\/li>\n<li>Pulsing feeling behind the knee.<\/li>\n<\/ul>\n<p>An aneurysm is a ballooning in a weak spot in an artery wall. Many different things can cause the popliteal artery wall to become weak, including:<\/p>\n<ul>\n<li>Atherosclerosis.<\/li>\n<li>High blood pressure.<\/li>\n<li>Wear and tear of the popliteal artery due to repeat use of the knee joint.<\/li>\n<\/ul>\n<p>Popliteal artery aneurysms are rare. They are more common in men than in women.<\/p>\n<p>Popliteal artery aneurysm often occurs in men with abdominal aortic aneurysm (AAA). An abdominal aortic aneurysm is a swelling of the wall of the body&#8217;s main artery, called the aorta. Anyone diagnosed with popliteal artery aneurysm should be screened for <abbr title=\"abdominal aortic aneurysm\">AAA<\/abbr>.<\/p>\n<p>Other risk factors for popliteal artery aneurysm include:<\/p>\n<ul>\n<li>Growing older.<\/li>\n<li>High blood pressure.<\/li>\n<li>Rauchen.<\/li>\n<li>Narrowing of a heart valve.<\/li>\n<li>Having three or more aneurysms anywhere in the body.<\/li>\n<\/ul>\n<p>Complications of popliteal artery aneurysm include blood clots. Blood clots can cause a severe lack of blood flow in the lower leg.<\/p>\n<p>A severe lack of blood flow can cause the following symptoms:<\/p>\n<ul>\n<li>A change in skin color in the affected area.<\/li>\n<li>No pulse behind the knee.<\/li>\n<li>Skin in the affected area feels cold.<\/li>\n<li>Numbness in the leg.<\/li>\n<li>Inability to move the foot.<\/li>\n<\/ul>\n<p>A severe lack of blood flow may result in loss of the limb. Rarely, the aneurysm may rupture. But the risk of popliteal artery aneurysm rupture is low.<\/p>\n<p>Smoking and high blood pressure increase the risk of blood vessel problems that can lead to popliteal artery and other aneurysms. Following a heart-healthy lifestyle can help prevent heart disease and blood vessel damage.<\/p>\n<p>Try these heart-healthy tips:<\/p>\n<ul>\n<li>Do not smoke.<\/li>\n<li>Eat a nutritious diet.<\/li>\n<li>Treiben Sie regelm\u00e4\u00dfig Sport.<\/li>\n<\/ul>\n<p>To diagnose popliteal artery aneurysm, a health care professional usually does a physical exam and checks the legs for:<\/p>\n<ul>\n<li>Swelling.<\/li>\n<li>Tenderness.<\/li>\n<li>Changes in skin color or temperature on the lower leg and behind the knee.<\/li>\n<\/ul>\n<p>You may be asked questions about your medical history and health habits, such as smoking.<\/p>\n<h3>Tests<\/h3>\n<p>Imaging tests can help confirm a diagnosis of popliteal artery aneurysm. Tests may include:<\/p>\n<ul>\n<li><strong>Duplex ultrasound.<\/strong> This test uses sound waves to see how blood flows through the arteries and veins. It&#8217;s a simple and quick way to diagnose popliteal artery aneurysm. For the test, a health care professional gently moves a hand-held ultrasound device on the skin behind and around the knee.<\/li>\n<li><strong><abbr title=\"Computerized tomography\">CT<\/abbr> angiography or magnetic resonance (MR) angiography.<\/strong> These tests take detailed images of blood flow in the arteries. Before the images are taken, dye called contrast is injected into a blood vessel. The dye helps the arteries show up more clearly.<\/li>\n<\/ul>\n<p>Treatment of popliteal artery aneurysm depends on:<\/p>\n<ul>\n<li>The size of the aneurysm.<\/li>\n<li>The symptoms.<\/li>\n<li>Your age and overall health.<\/li>\n<\/ul>\n<p>Treatment may include:<\/p>\n<ul>\n<li><strong>Regular health checkups.<\/strong> You&#8217;ll have frequent checkups and ultrasound tests to check the aneurysm, particularly if the aneurysm is small.<\/li>\n<li><strong>Medicines.<\/strong> Aspirin or another blood thinner is usually prescribed for people with popliteal artery aneurysm. Medicines may need to be given through a vein. Blood pressure and cholesterol medicine may be given if you have symptoms of heart disease.<\/li>\n<li><strong>Surgery.<\/strong> Open surgery to repair the damaged artery is generally recommended for any sized popliteal artery aneurysm that&#8217;s causing symptoms. Surgery is usually done for any popliteal artery aneurysm that&#8217;s 0.8 inches (2 centimeters) or larger. Sometimes, a less invasive procedure called endovascular repair may be done. During this treatment, a stent is placed inside the popliteal artery to hold it open.<\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Learn more about this lower extremity aneurysm that occurs in the wall of an artery located behind the knee.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[1686,1685,1682],"class_list":["post-52652","mayo","type-mayo","status-publish","hentry","tag-anatomical-structure","tag-condition","tag-person-group-concept","content_type-diseases-conditions"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
