The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'. [1]
Very rarely, the inferior pancreaticoduodenal artery may have an aneurysm. [3] It may be caused by certain medical interventions, major trauma, pancreatitis, cholecystitis, and vasculitis and other infections. [3] A ruptured aneurysm causes abdominal pain, and haemorrhage leads to hypotension. [3] It may be treated with open abdominal surgery. [3]
Superior mesenteric artery compressing the duodenum, featuring the superior mesenteric artery syndrome. Superior mesenteric artery (SMA) syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery.
It is a branch of the gastroduodenal artery, which most commonly arises from the common hepatic artery of the celiac trunk, although there are numerous variations of the origin of the gastroduodenal artery. [1] The pancreaticoduodenal artery divides into two branches as it descends, an anterior and posterior branch.
A true aneurysm is one that involves all three layers of the wall of an artery (intima, media and adventitia).True aneurysms include atherosclerotic, syphilitic, and congenital aneurysms, as well as ventricular aneurysms that follow transmural myocardial infarctions (aneurysms that involve all layers of the attenuated wall of the heart are also considered true aneurysms).
The retroduodenal arteries are several [1] [2] small [2] arteries which usually [1] arise from the gastroduodenal artery [1] [2] posterior to the superior part of duodenum, but may also arise from the posterior superior pancreaticoduodenal artery.
The right gastroepiploic artery (or right gastro-omental artery) is one of the two terminal branches of the gastroduodenal artery.It runs from right to left along the greater curvature of the stomach, between the layers of the greater omentum, anastomosing with the left gastroepiploic artery, a branch of the splenic artery.
The aortic aneurysm is a special case where the aorta, the body's main blood vessel, becomes ruptured through an inherent weakness, although exertion, raised blood pressure or sudden movements could cause a sudden catastrophic failure. [23] This is one of the most serious medical emergencies a patient can face, as the only treatment is rapid ...
