Popliteal Artery Aneurysm – How serious is a popliteal aneurysm?

popliteal artery aneurysm means focal dilatation of this vessel – abnormal expansion of its wall (in the form of a protrusion), which leads to an increase in the lumen relative to the normal diameter of at least 150%.

This is a proplem of the circulatory system, of which arterioles are a part and, according to ICD-10, its code is I72.4 (popliteal artery aneurysms and arterial layers of the lower extremities).


Popliteal artery aneurysm is a rare disease, and its frequency in the population is estimated to be 0.1-1%. However, among peripheral arterial aneurysms, it is the most common: popliteal artery aneurysms accounts for 70-85% of aneurysms of the lower extremities.

As clinical statistics show, the prevalence of this disease increases with age, reaching a maximum incidence after 60-70 years.

The main patients (95-97%) are men (most likely because of their predisposition to atherosclerosis).

The presence of popliteal artery aneurysm of the popliteal artery in 7-20% of cases (according to other sources, in 40-50%) is associated with aneurysms of other vessels.

Specially, in individuals with an abdominal aortic aneurysm, the incidence of popliteal artery aneurysms is 28% higher than in the general population.

In addition, in 42% of patients (according to other data, in 50-70%) a lateral or bilateral popliteal artery aneurysm was observed.

What is the criteria for a popliteal artery aneurysm?

What is a popliteal artery aneurysm?

A peripheral popliteal artery aneurysm is a condition occurs in the popliteal artery, which is positioned behind the knee joint and supply blood to the lower limbs, turns into abnormally dilated and weakened.

Popliteal artery aneurysms can be due to atherosclerosic plaques, a buildup of plaque at the internal walls of the artery, or by way of a connective tissue ailment including Marfan syndrome or Ehlers-Danlos syndrome.

Popliteal artery aneurysms are more common in men and in older adults, and they may no signs appear in tje start. however, as popliteal artery aneurysms grows larger, popliteal aneurysms are able to compress the encircling nerves and vessels, lead to ache, numbness, and tingling within the lower limbs and foot.

In some instances, a clot may also shape in popliteal artery aneurysm and reason a blockage, which can lead to acute limb ischemia and tissue harm.

What is ICD-10 code for left popliteal artery aneurysm?

The ICD-10 code for popliteal artery aneurysm is I72.3.

This code falls underneath the category of “popliteal artery aneurysms and dissection of artery, unspecified site.”

The area of the peripheral aneurysm is known through using extra codes that specify the affected site, in this case, “left popliteal artery.” the whole code might seem like this: I72.3 – Aneurysms and dissection of artery, unspecified site, with “popliteal artery aneurysm” as the extra descriptive diagnosis.

What are popliteal artery aneurysm complications?

Popliteal artery aneurysms can cause a number complications, including:

1. Blood clots: A clot can shape inside the peripheral popliteal artery aneurysms, leading to a blockage of blood vessels to the lower legs and foot. this could cause acute ischemic limb, tissue harm, and even gangrene.

2. Embolism: portions of the clot can destroy off and travel downstream, causing a blockage in smaller vessels within the leg or foot.

3. Rupture: In NOT common cases, popliteal artery aneurysms can rupture, causing intense bleeding and doubtlessly lifestyles-threatening complications.

4. Nerve compression: because popliteal artery aneurysms (PAA) grow larger, it may compress the surrounding nerves, lead to pain, numbness, and tingling within the lower leg and foot.

5. Limbs ischemia: reduced flow to the lower leg and foot can motive tissue damage and lead to persistentischemic limbs, which can purpose ache, ulcers, and even amputation in severe cases.

6. Pulmonary embolism: Clots that shape within peripheral popliteal artery aneurysms (PAA) can travel to the lungs, inflicting a blockage in the pulmonary artery and doubtlessly existence-threatening complications.

7. Cardiovascular complications: peripheral popliteal artery aneurysm (aneurysms) (PAA) is often associated with different cardiovascular sicknesses, together with atherosclerosis, which could increase the hazard of heart attack and stroke.

Peripheral popliteal artery aneurysm (aneurysms) can also contain tracking the popliteal artery aneurysm, medicine to manage symptoms and prevent clot, and surgical procedure to restore or dispose of the aneurysm (aneurysms), relying on the size and vicinity of the aneurysm (aneurysms) and the affected person’s typical fitness.

Early detection and remedy can assist save you complicationsand enhance outcomes.

How to diagnose popliteal artery aneurysm?

Peripheral popliteal artery aneurysm (aneurysms) can be identified thru a mixture of scientific history, physical exam, and diagnostic checks.

Here are the most usual methods used for diagnosis:

1. Medical records: Your healthcare provider will ask about your signs, medical records, and any danger factors for vascular ailment, inclusive of smoking, high pressure, or diabetes

2. Physical exam: at some point of a physical examination, your healthcare company will check your pulses on your legs and feet and search for any signs and symptoms of swelling or discoloration.

They’ll also use a stethoscope to listen for abnormal sounds, which includes a bruit, that may imply an popliteal artery aneurysm (PAA).

3. Imaging exams: Imaging assessments, such as ultrasound, CT angiography, or magnetic resonance angiography (MRA), are used to visualise the vessels and discover any abnormalities, which includes an aneurysm (aneurysms).

Those assessments can also provide records approximately the size, site, and shape of the popliteal artery aneurysm (aneurysms).

As soon as a peripheral popliteal artery aneurysm (aneurysms) is identified, your healthcare company will decide the perfect treatment based totally on the size, location, and symptoms of the popliteal artery aneurysm (PAA), as well as your ordinary fitness and person situations.

Options might also consist of observation and monitoring, medicinal drugs ,open surgically restore, or thrombectomy or embolectomy.

Early detection and remedy of a popliteal artery aneurysm (aneurysms) common help save you complications and improve consequences.

What is the criteria for a popliteal artery aneurysm?

What are the treatment options for popliteal artery aneurysm (PAA)?

1. Observation and monitoring: If the peripheral popliteal artery aneurysm (aneurysms) is small and now not inflicting any signs, it may be monitored with regular checks, including ultrasound or CT angiography, to test for any adjustments in length or form.

This approach is common used for patients who aren’t suitable applicants for surgically or endovascularity repair, including older adults or people with other medical conditions.

2. Medicinal drugs: we common used medicinal drugs together with antiplatelet or anticoagulants medications which can be prescribed to control symptoms consisting of ache, numbness, or tingling inside the lower leg and foot, and to save you clot from forming within the peripheral popliteal artery aneurysm (PAA).

Those medicinal drugs are common prescribed in observation with monitoring.

3. Endovascular Surgery: Endovascularity repair is a minimally invasive process that entails putting a stent graft within the peripheral popliteal artery aneurysm (PAA) to boost the weakened artery partitions and common prevent it from rupturing or cause other headaches.

This is common achieved beneath nearby anesthesia and through a small incision in the groin or upper thigh.

Endovascularity surgery is usually endorsed for sufferers who’re top applicants for the manner and have an popliteal aneurysm that is not too large or complicated.

4. Open surgically repair: In instances in which the popliteal aneurysm (PAA) is large or complex, or if endovascularity surgery isn’t always viable or secure, open surgically restore may be essential.

This includes making an incision in the leg and doing away with the broken section of the artery aneurysm and replacing it with a graft manufactured from artificial material or a vein from any other part of the body.

Open surgically restore is normally finished underneath fashionable anesthesia and requires an extended recuperation time than endovascularity restore.

5. Thrombectomy or embolectomy: If ablood clot has formed in the popliteal aneurysm or aneurysms (PAA), a thrombectomy or embolectomy may be accomplished to take away the clot and restore flow.

That is common accomplished using minimally invasive techniques, which includes a catheter-primarily based approach, and can be combined with endovascular or surgically restore if important.

The choice depends on the scale, area, and symptoms of the popliteal aneurysm (PAA), as well as the patient’s average fitness and character situations. Your healthcare issuer can help determine which alternative is first-rate for you.

Early detection of popliteal artery aneurysm can assist prevent complications and enhance outcomes.

What are risks associated with each treatment option?

1. Observation and monitoring: the principle hazard related to that is that the peripheral popliteal aneurysm may develop or rupture, main to doubtlessly lifestyles-threatening complications. but, this hazard is usually low for small popliteal aneurysms that are not cause any signs and symptoms.

2. Medicinal drugs: the threat associated with medicinal drugs is bleeding, as those drugs can boom the risk of bleeding or bruising. In uncommon cases, those medicines also can purpose more severe bleeding, along with gastrointestinal bleeding or bleeding within the brain

3. Endovascular repair: The risks related to endovascular restore include bleeding, infection, and damage to the artery or surrounding tissue.

There is also a hazard that the stent graft in popliteal aneurysms might also flow or come to be blocked, that may reason clot or other complications.

4. Open surgical restore : The risks associated with open surgical restore of popliteal aneurysms encompass bleeding, infection, and damage to the artery or surrounding tissue.

There’s additionally a threat of complications related to anesthesia, which includes allergic reactions or breathing issues.

Restoration time is longer than with endovascular restore of popliteal aneurysms, and there is a better hazard of wound complications, such as infection or bad healing.

5. Thrombectomy or embolectomy: The risks related to thrombectomy or embolectomy consist of bleeding, contamination, and harm to the artery or surrounding tissue.

There is also a chance of dislodging the clot and inflicting it to travel downstream, that could purpose similarly blockages or compications.

It is essential to be aware that these dangers range of how it is common according to the specific patient and their individual occasions.

Your healthcare provider can help you apprehend the risks and benefits of every option and help you’re making an knowledgeable selection approximately your care.
