What are pseudoaneurysms?
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.
How serious is a splenic artery aneurysm?
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.
Is a splenic artery aneurysm an emergency?
Splenic artery aneurysm (SAA) is an uncommon, but potentially life-threatening, condition.
Where are pseudoaneurysms located?
Pseudoaneurysms can develop in any artery, but they’re most common in the femoral artery, especially if you’ve undergone a cardiac catheterization procedure. A pseudoaneurysm can also be caused by: trauma. surgical procedures.
Do pseudoaneurysms bleed?
Bleeding pseudoaneurysms are a rare cause of delayed hemorrhage but these delayed hemorrhages are among the most serious and fatal complications following pancreaticoduodenectomy. A decade ago, diagnostic or therapeutic endoscopy followed by laparotomy was the treatment strategy for delayed massive hemorrhage.
Why do pseudoaneurysms form?
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.
What size splenic artery aneurysm requires surgery?
In the absence of guidelines, the main recommended indications for intervention of splenic artery aneurysm are rupture, aneurysm size larger than 2 or 2.5 cm, growth of the aneurysm by 3 to 5 mm or more during surveillance regardless of initial size, symptoms, women of childbearing age, portal hypertension, and planned …
How do they fix a splenic artery aneurysm?
Any splenic artery aneurysm with a significantly increased risk of rupture requires a prompt intervention. Although percutaneous embolization of the splenic artery is the most frequently applied therapy today, surgical repair is preferred for all symptomatic aneurysms because of the greater likelihood of success.
What is the treatment for splenic artery aneurysm?
Fusiform true aneurysms are better treated with a stent graft (covered stent), while tortuous, saccular aneurysms are treated with aneurysmal coiling techniques. Pseudoaneurysms can be treated with embolization using liquid embolic agents to thrombose the inflow and outflow arteries or filling the sac itself.
How long can you live with a pseudoaneurysm?
Methods: 10 patients with postinfarction left ventricular pseudoaneurysm were followed up over a mean (SD) period of 3.8 (5.2) years. Results: In those treated conservatively (n = 9), cumulative survival was 88.9 (10.5)% and 74.1 (16.1)% at one and four years, respectively.
Do pseudoaneurysms burst?
A pseudoaneurysm, or false aneurysm, is swelling of the wall of the artery. The swelling is caused by a small hole that has not sealed. A pseudoaneurysm can happen in any artery. It may become a medical emergency because the pseudoaneurysm can rupture.
How do you get rid of a splenic artery aneurysm?
The treatment options again are open surgery (mandatory in the setting of rupture), endovascular procedures, and laparoscopic surgery. Open surgical procedures include ligation of the splenic artery or aneurysm and aneurysmectomy with or without splenectomy.
How common is a splenic artery aneurysm?
Splenic artery aneurysm occurs in approximately 0.1% of all adults. It is estimated that 6% to 10% of splenic artery aneurysms will rupture, and 25% to 40% of those ruptures will occur during pregnancy, especially during the third trimester. Risk factors for rupture include portal hypertension and pregnancy.
What causes spleen artery aneurysm?
Splenic artery pseudoaneurysms are thought to be caused by pancreatitis, abdominal trauma, postoperative cases of liver transplant and rarely peptic ulcer disease. The most common cause is considered to be chronic pancreatitis.
How serious is a pseudoaneurysm?
If you think you might have a pseudoaneurysm, you should call your doctor. If you don’t have the condition treated, you’re at risk of severe complications. The buildup of blood can damage circulation in the area and cause tissue death. You are also at risk for the bleeding to get worse and lead to hemorrhage.
Is a pseudoaneurysm an emergency?
Pseudoaneurysms result from traumatic arterial injury. With the increasing utilization of percutaneous arterial interventions, iatrogenic arterial injury has become the predominant cause of pseudoaneurysm formation. Rupture of the pseudoaneurysm comprises a vascular emergency.
Can you live with a splenic aneurysm?
The overall mortality rate from rupture of splenic artery aneurysm is 25%, with ruptures during pregnancy carrying a particularly high mortality of up to 75%. Pseudoaneurysms of the splenic artery are at higher risk of rupture than true aneurysms and should be treated regardless of size or symptoms.
