Splenic artery aneurysm is defined as a condition where there is a focal dilation in the diameter of the splenic artery that is 50% greater than the normal vessel diameter. This is the most common visceral artery aneurysm reported making up about 60% to 70% of patients diagnosed with visceral artery aneurysms.
The spleen is an abdominal organ that forms part of the immune system. It has a large artery that supplies blood to it. When a portion of this artery balloons or widens because of weakness in its walls, an aneurysm develops. Other more common intra-abdominal aneurysms affect the aorta and the iliac arteries.
Treatment is recommendedfor the following groups:

Aneurysm of other specified arteries I72. 8 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I72. 8 became effective on October 1, 2021.
A pseudoaneurysm happens as a result of injury to a blood vessel. The artery leaks blood, which then pools near the damaged spot. It's different from a true aneurysm, which happens when the wall of a blood vessel stretches and forms a bulge. Most pseudoaneurysms are complications from medical procedures.
Splenic artery aneurysm is a rare condition, however, potentially fatal. The importance of splenic artery aneurysm lies in the risk for rupture and life threatening hemorrhage.
Brain aneurysm is assigned to ICD-9-CM code 437.3, Cerebral aneurysm, nonruptured. Code 437.3 also includes an aneurysm of the intracranial portion of the internal carotid artery.
ICD-10 code I71. 4 for Abdominal aortic aneurysm, without rupture is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
The three types of cerebral aneurysms are: berry (saccular), fusiform and mycotic. The most common, "berry aneurysm," occurs more often in adults. It can range in size from a few millimeters to more than two centimeters. A family history of aneurysms may increase your risk.
A pseudoaneurysm, or pseudoaneurysm of the vessels, occurs when a blood vessel wall is injured and the leaking blood collects in the surrounding tissue. It is sometimes called a false aneurysm. In a true aneurysm, the artery or vessel weakens and bulges, sometimes forming a blood-filled sac.
There are three types of aneurysms: abdominal aortic, thoracic aortic, and cerebral.
Patients with a splenic artery aneurysm before rupture are fairly asymptomatic; vague epigastric pain, left upper quadrant pain, and left shoulder pain are among the most common complaints. Radiologic studies for the diagnosis of splenic artery aneurysm include plain abdominal film, ultrasound, and angiography.
Atherosclerotic disease (cholesterol buildup in arteries) may also lead to the formation of some aneurysms. Certain genes or conditions such as fibromuscular dysplasia can result in aneurysms. Pregnancy is often linked to the formation and rupture of splenic artery aneurysms.
Endoscopic ultrasonography can also assist in the diagnosis and differentiate splenic artery aneurysm from nearby splenic and pancreatic pathology, such as pancreatic pseudocyst. Catheter angiography, although invasive, continues to be the gold standard for characterizing the aneurysm's location, size, and extent.
Aneurysms are classified by location, etiology, or other characteristics. Pathological, blood-filled distension of blood vessel. Protruding sac in the wall of a vein, artery, or heart, frequently caused by microbial infection; may present as pain, pressure on nearby organs, or cardiac weakening.
Medicines and surgery are the two main treatments for aneurysms. Bulging or ballooning in an area of an artery secondary to arterial wall weakening. Pathological outpouching or sac-like dilatation in the wall of any blood vessel (arteries or veins) or the heart (heart aneurysm).
Most aneurysms occur in the aorta, the main artery traveling from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the brain, heart and other parts of the body. If an aneurysm in the brain bursts, it causes a stroke. Aneurysms can develop and become large before causing any symptoms.
Spontaneous rupture of splenic artery aneurysms that are asymptomatic and are less than 2 cm in diameter is rare, especially in patients with no risk factors.
Treatment consists of putting steel or platinum coils into the artery to block the aneurysmal portion.
Other possible signs and symptoms may include the following: 1 Vague abdominal pain and nausea/vomiting. 2 Compression symptoms affecting adjacent organs. 3 Severe pain on the left side of the abdomen may be due to acute expansion or rupture of the aneurysm. 4 Abdominal distension, shock, and death may occur due to rupture into the peritoneum. 5 In up to 30% of cases, double-rupture may occur, which means rupture of the aneurysm into the lesser sac, followed by intraperitoneal rupture. 6 Rupture involving the splenic vein, the gastrointestinal tract, or the pancreatic ducts.
Multiparity and pregnancy-associated hormonal effects as well as portal hypertension are believed to cause dilatation of the weak walls of the splenic artery. Other possible causes include congenital defects such as berry aneurysms ...
For patients who have aneurysms that are at least 2 cm in diameter, endovascular therapy is recommended. Management of large aneurysms may include coil embolization. Regardless of size, surgical intervention may be indicated for rapidly increasing aneurysms, symptomatic aneurysms, cirrhosis, and presence of aneurysm in premenopausal women.
The risk of late failure is small with these techniques, but continued observation is important. Traditional surgery to close off the artery with a clip or ligature may be done. In some cases, splenectomy (removal of the spleen) may be necessary especially if the aneurysm lies very close to the spleen.
Initially, most patients do not experience any symptoms, and a splenic artery aneurysm may be diagnosed incidentally on imaging. However, some patients experience nausea, vomiting and abdominal pain. In some patients, serious life-threatening complications like rupture of the aneurysm can occur. Physical examination may be normal, ...
