よくある質問

What is the retroduodenal artery?
The retroduodenal artery is a branch of the gastroduodenal artery that supplies the posterior surface of the proximal duodenum. It provides an important component of the posterior duodenal blood supply.
Where is the retroduodenal artery located?
The retroduodenal artery arises from the gastroduodenal artery and courses posteriorly to supply the posterior wall of the first and proximal second parts of the duodenum, running behind the duodenum in the retroperitoneal space.
What is the function of the retroduodenal artery?
The retroduodenal artery delivers oxygenated blood to the posterior surface of the proximal duodenum, complementing the supraduodenal artery's supply of the anterior and superior surfaces.
What conditions may be associated with the retroduodenal artery?
The retroduodenal artery is closely related to the posterior wall of the duodenal bulb—a site prone to peptic ulceration—and erosion of this artery by a posterior duodenal ulcer may be associated with significant upper gastrointestinal hemorrhage.
What does the retroduodenal artery look like?
The retroduodenal artery is a small arterial vessel running posterior to the proximal duodenum, arising from the gastroduodenal artery. It is visualized on CT angiography or selective celiac/superior mesenteric arteriography.
