How to treat a pseudoaneurysm?
If the pseudoaneurysm is wider than 2 centimeters, or if you take certain medications such as blood thinners, your doctor will likely recommend one of these treatments: 1 Ultrasound-guided compression repair. In this treatment, your doctor will look for your pseudoaneurysm using ultrasound imaging. Once the pseudoaneurysm is found, your doctor presses on it to release the built-up blood. 2 Ultrasound-guided medication. In this treatment, your doctor uses ultrasound imaging to locate and inject a blood clot-forming medication (thrombin) into the pseudoaneurysm. The medication causes the pooled blood to clot. 3 Surgery. If your doctor doesn't think either ultrasound-guided treatment will work, he or she may recommend surgery to correct it.

What causes aortic pseudoaneurysms?
Aortic pseudoaneurysms due to blunt trauma are theorized to be caused in large part by deceleration forces between the relatively free aortic arch against the relatively fixed descending aorta, especially at the point where the ligamentum arteriosum anchors the aorta to the pulmonary artery.
Is a pseudoaneurysm a splenic artery?
Visceral pseudoaneurysms are very rare and are related to iatrogenic injury from surgery or endovascular procedures, or pancreatitis, which typically presents as a splenic artery pseudoaneurysm, which is due to the digestive action of pancreatic enzymes on the artery.[9] Unlike true aneurysms, visceral pseudoaneurysms appear in myriad locations.

What is a pseudoaneurysm?
A pseudoaneurysm is a contained rupture of a blood vessel or of the myocardial wall. Typically, pseudoaneurysms will have to-and-fro blood flow into a cavity contained by pericardium, thrombus, or adhesions. This contrasts with a true aneurysm that forms as a result of a weakness rather than a rupture of the wall that typically bulges outward during systole, is thin, and has an outer layer that contains all layers of the myocardium or vessel wall. A pseudoaneurysm will typically have a narrow neck, with a ratio of the breach in the wall to the maximal diameter of the pseudoaneurysm of <50%. In contrast, a true aneurysm has a broad base. 1 Although distinguishing true from false aneurysms often proves challenging, differentiating these 2 entities has clinical relevance because a patient with pseudoaneurysm will have a greater risk of rupture and should thus be considered for immediate repair.
What are the symptoms of a pseudoaneurysm?
Patients with cardiac pseudoaneurysm often present with symptoms of chest pain or heart failure. If the rupture is not entirely contained or a previously contained pseudoaneurysm ruptures, a patient may present with tamponade, shock, or sudden death. Examination may reveal volume overload indicative of congestive heart failure, and a murmur is often present. However, among the population at risk (who often have a history of prior cardiac procedures, valvular heart disease, or myocardial infarction), these signs and symptoms are neither sensitive nor specific for pseudoaneurysm. Therefore, imaging is usually required to diagnose a pseudoaneurysm or to identify the presence of other pathology accounting for the patient's signs and symptoms. Initial evaluation with transthoracic echocardiography may be unrevealing, but in suspected cases, angiography, transesophageal echocardiography, cardiac CT, and cardiac MRI will have a higher diagnostic yield.
Can an aneurysm be a false aneurysm?
In clinical practice, distinguishing true from false aneurysms of the heart often proves difficult because a true aneurysm may present with a narrow neck and false aneurysm at times may have a rather broad base. Thus, autopsy or surgical evaluation of tissue layers remains the gold standard for diagnosis.
