What causes splenic artery pseudoaneurysm?
What causes splenic artery pseudoaneurysm?
The causes of splenic artery pseudoaneurysm include pancreatitis (Fig. 6A, 6B), trauma, iatrogenic and postoperative causes, and, rarely, peptic ulcer disease [5].
How is pseudo aneurysm detected after cardiac catheterization?
A small pseudoaneurysm of a femoral artery due to cardiac catheterization may go undetected and not cause any complications. You may not notice it until days or weeks after the procedure. Your doctor may recommend a watchful-waiting approach and an occasional duplex ultrasound test to see if it goes away on its own.
What is hepatic artery pseudoaneurysm?
Hepatic artery pseudoaneurysm (HAP) is a rare complication of acute or chronic surgical injury to the hepatic artery. Sethi et al. [1] reported that 19% of pseudoaneurysms due to pancreatitis occur in the hepatic artery.
How serious is a pseudoaneurysm?
Small pseudoaneurysms may resolve spontaneously without intervention. On the contrary, persistent pseudoaneurysms may enlarge and lead to complications related to compression of the adjacent femoral vein, nerve and overlying skin. This may cause leg edema, deep vein thrombosis, compressive neuropathy and skin necrosis.
What is the difference between pseudoaneurysm and aneurysm?
A saccular-shaped aneurysm bulges or balloons out only on one side. A pseudoaneurysm, or false aneurysm, is not an enlargement of any of the layers of the blood vessel wall. A false aneurysm may be the result of a prior surgery or trauma. Sometimes, a tear can occur on the inside layer of the vessel.
Where is the splenic artery?
The splenic artery is one of the terminal branches of the celiac trunk, passing left from the celiac axis across the left crus of diaphragm and left psoas muscle. It is a tortuous artery, running superior to the pancreas before turning forward into the splenorenal ligament to the hilum of the spleen.
How painful is a pseudoaneurysm?
Pseudoaneurysms usually present as a painful, tender, pulsatile mass. The overlying skin is sometimes erythematous (red). They can sometimes be confused with abscesses. The patient may describe a history of catheterization or trauma, and they may note that the pulsatile mass is gradually expanding.
Which blood vessel is most commonly damaged resulting in pseudoaneurysm?
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.
What are hepatic arteries?
The hepatic artery proper (also proper hepatic artery) is the artery that supplies the liver and gallbladder. It raises from the common hepatic artery, a branch of the celiac artery.
How long does it take to recover from pseudoaneurysm?
A small pseudoaneurysm may close on its own in about 4 weeks. You may need any of the following to treat a pseudoaneurysm that does not close: Debridement is a procedure used to remove dead tissue. You may need this if the area around your pseudoaneurysm becomes infected.
Why is the splenic artery tortuous?
Splenic artery also called as the lienal artery, is the largest branch of celiac trunk. The difference in the increasing length of the artery and the distance between its origin and the splenic hilum makes the artery tortuous. The proximal part of the artery is more tortuous than the distal part [7].
Is splenic artery an end artery?
Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.
Is there a pseudo aneurysm in the gastroduodenal artery?
A truncated right gastroduodenal artery was identified and there was no active contrast extravasation or pseudo-aneurysm formation. Further interrogation of this segment of the vessel with a microcatheter showed contrast extravasation hence embolized using multiple coils.
Is it possible for a GDA aneurysm to rupture?
Gastroduodenal artery (GDA) aneurysms are rare but a potentially fatal condition if rupture occurs. They represent about 1.5% of all visceral artery (VAA) aneurysms and are divided into true and pseudoaneurysms depending on the etiologic factors underlying their development.
How is pseudoaneurysm related to the pancreatic neck?
The pseudoaneurysm is closely related to the pancreatic neck with effacement of the neck. Heterogeneous material in the stomach and history of massive hematemesis in keeping with rupture of the pseudoaneurysm in to the pylorus however active extravasation from the pseudo-aneurysm into the stomach is not identified. IVC filter in situ.
Can a gastroduodenal artery aneurysm ( Vaa ) be fatal?
Abstract Gastroduodenal artery (GDA) aneurysms are rare but a potentially fatal condition if rupture occurs. Visceral artery aneurysms (VAA) are infrequent conditions characterized by a wide range of clinical presentations and various clinical outcomes.
