Popliteal artery aneurysm : Causes - Symptoms- Diagnosis -Treatment

 What is Popliteal artery aneurysm?

A popliteal artery aneurysm is outlined as a focal dilation within the artery, with the biggest diameter being quite five hundredth of the traditional. These focal dilations are classified as either pointed or saccular. Artery aneurysms are related to abdominal artery aneurysms four-hundredth to five hundredth of the time. they're typically well, however might give with chronic symptoms thanks to mass result. This activity describes the chance factors, diagnosis, and management of busted artery aneurysms and therefore the role of the interprofessional team in caring for affected patients.

The artery is outlined as aneurismatic once focal dilation in its diameter is quite five hundredth of the traditional vessel diameter. The traditional diameter of the artery varies from zero.7 to 1.1 cm. These focal dilations classify as pointed (diffuse dilation) or saccular (asymmetrical). artery aneurysms (PAAs) account for eighty fifth of all peripheral aneurysms. Artery aneurysms are related to abdominal artery aneurysms four-hundredth to five hundredth of the time.

What is Popliteal artery aneurysm?
Popliteal artery aneurysm

The artery is taken into account as a continuation of the superficial arteria femoralis when it passes through the adductor muscle magnus hiatus. It lies within the ginglymus fossa incidental its vein and terminates at the bifurcation into the anterior leg bone artery and tibioperoneal trunk, that is found at the lower border of the popliteus muscle at the extent of the leg bone tubercle.

Modifiable risk factors embrace smoking, arteriosclerosis, animal tissue disorders like Marfan syndrome, and Ehler-Danlos syndrome. Non-modifiable risk factors embrace advanced age, male gender, White race, and case history of illness} disease.

The exact incidence of artery cardiovascular disease isn't called no population-based study has been published; but, many series studies issued by completely different establishments counsel that artery cardiovascular disease prevalence will increase with age and peaks within the sixth or seventh decades of life. The incidence of limb and ginglymus aneurysms in persons with abdominal artery aneurysms (AAA) seems over the final population. In one study of 225 patients, twenty eighth (n=63) had a artery cardiovascular disease bigger than or adequate to ten.5 mm, nineteen (n=43) had a artery cardiovascular disease bigger than or adequate to 12mm and St Martin's Day (n=25) had a artery cardiovascular disease bigger than or adequate to fifteen millimeter.

The etiology of artery aneurysms, and aneurysms generally, is unknown. Molecular studies counsel that a mix of genetic defects and inflammatory processes could also be accountable. arteriosclerosis tends to extend flow turbulence distal to a stricture, resulting in a pathological dilation of the artery. belittled wall strength related to inflammatory cell infiltration is believed to lead to cardiovascular disease formation.

Medical terms

  • Popliteal artery aneurysm (PAA) is a condition in which an area of the artery in the back of the knee becomes enlarged. It can be caused by a variety of factors, including atherosclerosis, trauma, infection, and even genetic factors. If left untreated, a PAA can lead to serious complications, such as blood clots, blockages, or even rupture of the artery. Treatment for PAA is based on the size of the aneurysm and the risk for rupture.

  • Popliteal artery aneurysm (PAA) is a condition that occurs when the walls of the popliteal artery become weakened and dilated. It is a form of peripheral artery disease and is the most common type of aneurysm in the lower extremities. The most common symptom of PAA is a palpable mass in the popliteal fossa. Other symptoms may include pain, numbness, and swelling in the affected limb.

  • Most aneurysms of the leg are treated with surgery to place a metal clip across the weak wall of blood vessel thereby preventing it from enlarging and releasing blood Sometimes your doctor can use stents to prop up the weakened part of your blood vessel while it heals If you have had a blood clot in your leg you may be prescribed medication such as aspirin to prevent future clots.

  • An artery cardiovascular disease is AN irregular bulge that happens within the wall of the artery settled behind the genus. It's a sort of lower extremity cardiovascular disease.

Symptoms Popliteal artery aneurysm

Where the ginglymoid joint cardiovascular disease presents as Associate in Nursing emergency because of a shortage of blood to the leg. In spite of the scale, it ought to be treated as high risk to stop the potential amputation of the lower leg.

Traditionally, arteria aneurysms are treated surgically with open bypass surgical techniques. but endovascular techniques / hole surgery – that involve tubing graft (fabric lined metal mesh) through the arteria cardiovascular disease also can be used. Treatment can usually be determined by your health and age and also the quality of the intervention required.

An arterial blood vessel cardiovascular disease might not cause any noticeable symptoms. The primary symptom is also pain in the lower leg that happens with walking (claudication). different signs and symptoms of a arterial blood vessel cardiovascular disease include:

  • Knee pain

  • Lower leg pain

  • Swelling behind the knee

  • Pulsing sensation behind the knee

Causes Popliteal artery aneurysm

Arterial aneurysms will have an effect on any artery of our body (aorta, limbs, brain and internal organs). generally vessels will weaken and expand sort of a balloon, referred to as Associate in Nursing aneurysm. Additionally seldom, aneurysms may be caused thanks to trauma or surgical procedures leading to the injury of the arteries.

Wherever they occur among the body, aneurysms will result in limb loss or serious complications either within the kind of a burst or damaged artery or the sudden blockage of the artery (also referred to as acute ischaemia) thanks to the build-up of a clot within the aneurysm sac. The clot will block the artery at the extent of the aneurism or will become detached and travel among the blood, obstructing the circulation within the smaller arteries of the extremities.

An aneurism could be a flying {in a|during a|in Associate in Nursing exceedingly|in a very} weakness in an artery wall. many various things will cause the arterial wall to become weak, including:

  • Clogged arteries (atherosclerosis)

  • High blood pressure

  • Wear and tear of the popliteal artery due to repetitive use of the knee joint

  • Weakening of the artery wall

When to see a doctor

Seek immediate medical attention if you develop a:

If you are with somebody WHO complains of an unforeseen, severe headache or WHO loses consciousness or encompasses a seizure, decide 911 or your native emergency range.

Risk factors Popliteal artery aneurysm

Risk factors predisposing to the event of a PAA include: tobacco smoking, hardening of the arteries, animal tissue disorders (e.g. Marfan syndrome, and Ehlers-Danlos syndrome), advanced age (peaking within the sixth to seventh decade of life), male gender, White race, and a case history of cardiovascular disease.

Popliteal artery aneurysms are rare. they're more common in men than in ladies.

Popliteal artery aneurysms usually occur in men with abdominal aneurysm (AAA), a swelling of the wall of the body's main artery (aorta). Anyone diagnosed with arterial blood vessel cardiovascular disease ought to be screened for aortic aneurysm.

Other risk factors for popliteal artery aneurysm include:

  • Increasing age

  • High blood pressure (hypertension)

  • Smoking

  • Narrowing of a heart valve (stenotic disease)

  • Having three or more aneurysms anywhere in the body

Complications Popliteal artery aneurysm

Complications of arteria poplitea cardiovascular disease embrace blood clots (thrombosis) and, rarely, rupture of the cardiovascular disease. Occlusion of an arteria poplitea cardiovascular disease will cause a severe lack of blood flow (ischemia) within the lower leg, which can end in loss of the limb.

Sudden leg anemia will cause the subsequent signs and symptoms:

  • A change in skin color in the affected area

  • No pulse behind the knee

  • Skin in the affected area feels cold

  • Numbness in the leg

  • Inability to move the foot

The risk of popliteal artery aneurysm rupture is low.

Prevention Popliteal artery aneurysm

Smoking and high force per unit area (hypertension) increase the chance of vessel (vascular) issues that may cause arteria and alternative aneurysms. Following a wholesome manner — like not smoking, ingesting a nourishing diet and obtaining regular exercise — will facilitate forestall heart condition and vessel harm.

How serious is a popliteal aneurysm?

POPLITEAL ANEURYSM - a bulging artery in the calf Mild aneurysms are usually painless and do not cause any problems; however larger aneurysms may rupture causing widespread internal bleeding The blood vessels of the lower leg and foot contain many arteries which help send blood to the legs and feet Each of these small arteries branches from a large artery at the bottom of your leg .

What causes an aneurysm in the leg?

The main cause of aneurysm in the leg is high blood pressure When your heart beats it pumps blood into the arteries The arteries are elastic and expand as they fill with oxygen-rich blood High blood pressure then causes the arteries to stretch and weaken which can lead to an aneurysm High cholesterol levels also contribute to weak artery walls and a greater risk of developing an aneurysm in your leg or thigh Other factors include smoking diabetes family history and age because the older you get the weaker your arteries become from wear and tear during their lifespan—known as atherosclerosis.

What happens if a popliteal aneurysm ruptures?

People with a popliteal aneurysm are at risk of having the aneurysm rupture Signs and symptoms of ruptured popliteal aneurysm include: Sudden acute pain in the back of a thigh; often worse than any experienced before Swelling in the back of the affected leg around the knee (calf) Redness warmth or tenderness over the area where it is swollen (skin changes).

Diagnosis Popliteal artery aneurysm

The ginglymoid joint fossa is to be examined bilaterally with the knee in a very semi-flexed position. In some cases, the ginglymoid joint cardiovascular disease presents as a palpable pulsatile mass at the extent of the genus. Christian Johann Doppler sonography is the most popular diagnostic methodology. CT and adult male roentgenography may additionally be used.

To diagnose artery cardiovascular disease, a health care supplier can typically do a physical examination to envision swelling, tenderness, or changes in color or temperature on the lower leg and behind the knee. you will be asked questions on your anamnesis and health habits, like smoking.


Imaging tests will facilitate a designation of arterial blood vessel aneurysm. If you have got signs and symptoms of arterial blood vessel aneurysm, your health care supplier could recommend:

  • Duplex ultrasound. This noninvasive check uses sound waves to check however blood flows through the arteries and veins. It is easy and fast thanks to diagnosing arterial aneurysm. For the check, a healthcare supplier gently moves a little hand-held device (transducer) on the skin behind and round the knee. 

  • CT angiography or magnetic resonance (MR) angiography. CT and MR angiography provide detailed images of blood flow in the arteries. Before the images are taken, a contrast dye is injected into a blood vessel. The dye helps the arteries show up more clearly.

Treatment Popliteal artery aneurysm

It is unclear whether or not stenting or open surgery may be higher for those with aneurysms that aren't inflicting symptoms.

Treatment of artery aneurysm depends on the dimensions of the aneurism, the symptoms, and a human age and overall health.

Treatment could include:

  • Watchful waiting. This means you'll have frequent checkups and ultrasound tests to monitor the aneurysm, particularly if the aneurysm is small.

  • Medications. Aspirin or another blood diluent (anticoagulant) is typically prescribed for individuals with arterial cardiovascular disease. Anticoagulants may have to learn by IV. vital sign and steroid alcohol medications additionally could also be suggested to manage heart condition signs and symptoms. 

  • Surgery. Open surgery to repair the broken artery is mostly suggested for any sized popliteal artery cardiovascular disease that is inflicting symptoms or for any artery cardiovascular disease that is zero.8 inches (2 centimeters) or larger. Sometimes, a less invasive procedure (endovascular repair) is also done to position a tubing within the artery to carry it open. 

General summary

  1. An aneurysm is a weak area in a blood vessel When the vessel swells or bulges it's called an aneurysm An aneurysm can form anywhere in your body but the most common places are at the base of your brain the abdomen and pelvis and legs and arms.

  2. A popliteal artery aneurysm is a condition that occurs when there is an abnormal widening or bulging of the popliteal artery, which is the major blood vessel of the knee. It is usually caused by atherosclerosis, a progressive narrowing and hardening of the arteries due to plaque buildup. Popliteal artery aneurysms can be asymptomatic but can be dangerous if they become large enough to cause a blockage in the circulation or rupture. Treatment usually involves lifestyle modifications, medications, and in severe cases, surgery to repair the aneurysm.

  3. A popliteal artery aneurysm is a swelling of the artery found in the back of the knee. It occurs when the walls of the artery expand, usually due to a buildup of plaque, and can cause blockage and reduced blood flow. If left untreated, a popliteal artery aneurysm can cause serious health issues, such as stroke or amputation. As such, it is important to recognize the signs and symptoms of an aneurysm early on, and to seek medical help if any are noticed.

  4. A popliteal artery aneurysm (PAA) is a localized dilatation of the popliteal artery, the main artery that supplies blood to the lower legs and feet. PAA can present as a rare, but potentially life-threatening condition, as it can lead to severe and disabling symptoms if left untreated. The exact cause of PAA is unclear and can vary widely, but is often associated with certain medical conditions such as diabetes and peripheral artery disease. It is also known that certain lifestyle factors, such as smoking and high cholesterol levels, can increase the risk of developing PAA.
