What causes popliteal vein aneurysm?

What causes popliteal vein aneurysm?

Approximately 75% of these aneurysms are saccular and 25% are fusiform. Various etiologies associated with popliteal venous pathology have been suggested including congenital, trauma (e.g. arteriovenous fistula), varicose veins, localized degenerative changes, and inflammation.

How is a venous aneurysm treated?

Treatment of venous aneurysm includes either observation or surgical intervention (such as excision or ligation) or, less commonly, endovascular ablation. However, observation may be appropriate for asymptomatic superficial venous aneurysms— similar to our patient.

What is a popliteal vein aneurysm?

Popliteal venous aneurysms are rare than those of the popliteal artery and are mostly asymptomatic. However, due to the disturbance of the venous blood flow, they can lead to potentially life-threatening consequences, such as deep vein thrombosis (DVT) and pulmonary embolism (PE).

What is venous aneurysm?

A bulge in a weakened area of your vein Venous aneurysms form along a weakened wall of a vein, most often in your legs, abdomen, or neck. Aneurysms that burst can cause severe internal bleeding. Clots can also form in the aneurysms, leading to pulmonary emboli.

How is a popliteal aneurysm diagnosed?

Popliteal Aneurysms: Diagnosis & Treatment We can diagnose you through tests that include: Ultrasound. Computed tomography (CT) scan. Magnetic resonance imaging (MRI) scan.

Where does the popliteal vein drain into?

femoral vein
The popliteal vein is a deep vein of the leg. It drains blood away from the leg into the femoral vein, which drains blood to the inferior vena cava to return to the right atrium of the heart.

What is a Varix in the brain?

Cerebral varices, also known as cerebral venous aneurysms or isolated cerebral varices are uncommon cerebral vascular malformations, rarely found in isolation, hence the name isolated cerebral varix.

What aneurysm means?

An aneurysm is a ballooning at a weak spot in an artery wall. An aneurysm’s walls can be thin enough to rupture.

Can an aneurysm heal itself?

Aneurysms develop over a lifetime,” he says. “Another is that an aneurysm can disappear or heal itself. This is very rare and only happens in aneurysms that are considered benign because the flow of blood is so slow it eventually forms a clot and seals off the bulge.”

What does a leg aneurysm feel like?

Sudden pain in your leg or foot. Your leg or foot being cool or pale or changing color. Tingling or numbness in your foot.

What does popliteal drain?

The popliteal vein is a deep vein of the leg. It drains blood away from the leg into the femoral vein, which drains blood to the inferior vena cava to return to the right atrium of the heart.

What is a popliteal vein thrombosis?

The popliteal vein is one of the major blood vessels in the lower body. It runs up the back of the knee and carries blood from the lower leg to the heart. Sometimes, a blood clot, or a thrombosis, can block this important vein. This is known as a deep vein thrombosis (DVT). It can restrict circulation in your legs.

Is popliteal venous aneurysm a sign of pulmonary embolism?

Abstract. Popliteal venous aneurysms (PVA) are rare and in most cases the first sign of their presence is a pulmonary embolus or other thromboembolic events. We report four cases of PVA, in two of these the first sign of their presence was an acute pulmonary embolism; in two remaining cases the diagnosis was fortuitous.

What is the prevalence of vulvoperineal varicose veins?

Vulvoperineal varicosity is the most common unusual cause of lower limb varicose veins. The prevalence of varices in the perivulval area was reported as 4% in a large population study (, 2 ). In our study, vulvoperineal varicosity was found in 8.6% of cases.

Can Doppler US and CT venography identify the cause of varicose veins?

Doppler US with complementary CT venography is useful for determining the precise cause of varicose veins. Between November 2003 and March 2008, the authors evaluated 1350 cases of varicose veins in the lower extremities with both CT venography and Doppler US.
