Pancreaticoduodenal Artery Aneurysm Formation with Superior Mesenteric Artery Stenosis

Abstract

Celiac stenosis or occlusion is attributed partly to increase blood flow at pancreatic arcade from the superior mesenteric artery (SMA) system and may play a causal role in true aneurysm of pancreaticoduodenal artery (PDAA) formation. However, despite possible increased blood flow in the pancreatic arcades like celiac stenosis, PDAAs with a stenotic SMA are extremely rare, with only three cases have been reported in the literature. We report a case of PDAA with SMA stenosis and review the literature.

Superior pancreaticoduodenal artery pseudoaneurysm complicated with fistulation into common bile duct and duodenum: A case report

“…Clinical manifestations depend on the type of aneurysm. True aneurysms are associated with coeliac axis stenosis, while pseudoaneurysms are known to rupture into gastrointestinal tract as in this case [4,5]. Long standing alcohol use favors chronic pancreatitis as being the underlying cause.…”

“…Aneurysm of the pancreaticoduodenal artery is rare accounting for about 2% of all splanchnic aneurysms [4]. Clinical manifestations depend on the type of aneurysm.…”

“…False pancreaticoduodenal artery aneurysms occurs due to surrounding inflammatory response in cases like pancreatitis, abdominal trauma, septic emboli or laparoscopic cholecystectomy. They often rupture into the gastrointestinal tract, whereas true aneurysms are usually associated with coeliac axis stenosis, and rupture into the retroperitoneal space [3,4]. We present a case with pseudoaneurysm of superior pancreaticoduodenal artery fistulized into the duodenum.…”

“…Visceral artery aneurysms (VAAs) represent 0.1-0.2% of all vascular aneurysms and most commonly found in splenic (60%), hepatic (20%) and superior mesenteric (9%) arteries [1][2][3]. Pancreaticoduodenal artery aneurysms (PDAA) are rare, accounting for only 2% of all splanchnic artery aneurysms, but it is an important vascular disease because of its potential for fatal rupture [4]. False pancreaticoduodenal artery aneurysms occurs due to surrounding inflammatory response in cases like pancreatitis, abdominal trauma, septic emboli or laparoscopic cholecystectomy.…”

Pancreatic Arcade Artery Aneurysm—A Rare Complication after Replacement of Thoracoabdominal Aortic Aneurysm

“…5) Regarding the formation, that mechanism has been speculated that once the CA becomes stenotic or occluded, a flow and pressure within the pancreatic arcade relatively increase, resulting in subsequent development of the aneurysm. 6) Case Report CA. Aneurysms were confirmed in the inferior pancreaticoduodenal artery and at the first branch of the jejunal artery.…”
