An aneurysm is a bulging, weakened area in the wall of a blood vessel causing an abnormal widening or ballooning higher than 50% the the vessel"s common diameter (width). One aneurysm may occur in any kind of blood vessel, but is most often seen in an artery fairly than a vein.

You are watching: The ballooning of a weakened portion of an arterial wall is called

An aneurysm may be situated in many locations of the body, such together blood vessels of the mind (cerebral aneurysm), the aorta (the biggest artery in the body), the neck, the intestines, the kidney, the spleen, and the vessels in the legs (iliac, femoral, and popliteal aneurysms). The most usual location of an aneurysm is the aorta, i m sorry carries oxygenated blood indigenous the love to the body. The thoracic aorta is the quick segment that the aorta in the chest cavity. The abdominal muscle aorta is the section of the aorta the runs with the abdomen. An aneurysm can be identified by its location, shape, and also cause.

The shape of one aneurysm is described as gift fusiform or saccular, which help to recognize a true aneurysm. The more common fusiform-shaped aneurysm bulges or balloons out on all sides the the blood vessel. A saccular-shaped aneurysm bulges or balloons out only on one side.


A pseudoaneurysm, or false aneurysm, is not an enlargement of any kind of of the great of the blood vessel wall. A false aneurysm might be the an outcome of a prior surgical procedure or trauma. Sometimes, a tear can happen on the within layer of the vessel. As a result, blood fills in between the class of the blood vessel wall creating a pseudoaneurysm.

A dissecting aneurysm is one aneurysm the occurs v a tear in the artery wall surface that off the 3 layers of the wall, rather than ballooning out the whole wall.

Because an aneurysm may proceed to increase in size, along with progressive weakening that the artery wall, surgical intervention may it is in needed. Preventing rupture of one aneurysm is 1 of the purposes of therapy. The bigger an aneurysm becomes, the better the risk for rupture (bursting). With rupture, life-threatening hemorrhage (uncontrolled bleeding), and also possibly death, may result.


What reasons an aneurysm come form?

An aneurysm may be caused by multiple determinants that an outcome in the breaking under of the well-organized structural components (proteins) of the aortic wall surface that provide support and stabilize the wall. The exact reason isn"t totally known. Atherosclerosis (hardening that the arteries with a sticky substance referred to as plaque) is assumed to play critical role in aneurysmal disease. Threat factors linked with atherosclerosis include, but are not restricted to:

Older age


Family history

Genetic factors


Other particular causes that aneurysms are regarded the place of the aneurysm. Instances of aneurysms in the body and their added causes may include, but are not limited to:

Abdominal Aortic Aneurysm (AAA)

Atherosclerosis (especially in the segment the the abdominal muscle aorta listed below the kidneys, referred to as an infrarenal aortic aneurysm) genetic disorders gigantic cell arteritis (a an illness that causes inflammation the the temporal arteries and other arteries in the head and also neck, causing the arteries to narrow, to reduce blood flow in the impacted areas; may cause persistent headaches and also vision loss) Infection

Cerebral Aneurysm

Congenital (present at birth) High blood press Atherosclerosis Head trauma

Common Iliac Artery Aneurysm

Atherosclerosis pregnancy Infection Trauma after ~ lumbar or i know well surgery

Femoral and Popliteal Artery Aneurysm

Atherosclerosis Trauma Congenital disorders

What space the symptom of one aneurysm?

Aneurysms might be asymptomatic (no symptoms) or symptomatic (with symptoms). Symptoms connected with aneurysms rely on the location of the aneurysm in the body.

Symptoms the may happen with different varieties of aneurysms might include, but are not limited to:

Abdominal Aortic Aneurysm (AAA):Constant ache in abdomen, chest, lower back, or groin area Cerebral Aneurysm:Sudden serious headache, nausea, vomiting, visual disturbance, lose of awareness Common Iliac Aneurysm:Lower abdominal, back, and/or groin pains Femoral and also Popliteal Artery Aneurysm:Easily palpated (felt) pulsation the the artery situated in the groin area (femoral artery) or on the back of the knee (popliteal artery), pain in the leg, sores on the feet or reduced legs

The symptom of an aneurysm may resemble various other medical problems or problems. Constantly consult your medical professional for more information.

How are aneurysms diagnosed?

Selection of a type of diagnostic examination is related to the ar of the aneurysm. In enhancement to a finish medical background and physics examination, diagnostic procedures for one aneurysm may encompass any, or a combination, the the following:

What is the treatment for aneurysms?

Specific treatment will be established by your physician based on:

Your age, all at once health, and also medical history

Extent that the disease (location, size, and also growth rate of the aneurysm)

Your signs and symptoms

Your tolerance of specific medications, procedures, or therapies

Expectations for the food of the disease

Your opinion or preference

Treatment choices for an aneurysm may incorporate one or more of the following:

Routine ultrasound procedures. These measures will screen the size and also rate of growth of the aneurysm every 6 months to 12 months as part of a "watchful waiting" strategy for smaller aneurysms.

Controlling or editing risk factors. Steps such as quitting smoking, controlling blood sugar if diabetic, shedding weight if overweight or obese, and also controlling dietary fat entry may aid to control the development of the aneurysm.

Medication. Medication can manage factors such together hyperlipidemia (elevated levels of fats and also cholesterol in the blood) and/or high blood pressure.

Aneurysm open repair. An scratch is made to directly visualize and repair the aneurysm. A cylinder-like tube referred to as a graft may be offered to repair the aneurysm. Grafts room made of assorted materials, such together Dacron (textile polyester man-made graft) or polytetrafluoroethylene (PTFE, nontextile fabricated graft). This graft is sewn come the affiliated blood vessel, connecting 1 end of the artery in ~ the website of the aneurysm come the various other end. The open repair is thought about the surgical conventional for an abdominal aortic aneurysm repair

Endovascular aneurysm repair (EVAR). EVAR is a procedure that calls for only little incisions in the groin along with the usage of X-ray guidance and specially-designed tools to fix the aneurysm. V the usage of special endovascular instruments and also X-ray images for guidance, a stent-graft is placed via the femoral artery and advanced up right into the aorta come the website of the aneurysm. A stent-graft is a lengthy cylinder-like pipe made the thin steel mesh structure (stent), when the graft is do of assorted materials, such as Dacron or PTFE. The graft product may cover the stent. The stent help to organize the graft open and in place.
