Superior Mesenteric Artery Anatomy

The sma is the artery to the midgut. Superior mesenteric artery the artery of midgut it originates from the aorta about 1 cm below the celiac trunk at the level of the intervertebral disc between the first and second lumbar vertebrae behind body of pancreas 3.

Superior Mesenteric Artery The

The celiac artery lies at the level of the upper border of l1 lumbar vertebra and the superior mesenteric artery lies at the lower border of l1 lumbar vertebra.

Superior mesenteric artery anatomy. Left renal vein travels between the left kidney and the inferior vena cava. This compression causes partial or complete blockage of the duodenum. The inferior pancreaticoduodenal artery also supplies the head of the pancreas.

Anything that sharply narrows the angle between the aorta and superior mesenteric artery can cause compression of the duodenum resulting in smas. This artery branches off the abdominal aorta and supplies oxygenated blood to the pancreas and the lower parts of the intestine. The superior mesenteric artery forms an angle with the abdominal aorta due in part to the mesenteric fat pad and part of the duodenum sits within this angled space.

What we can see here is that just above the superior mesenteric artery is this celiac artery. The artery branches into several other blood vessels including the inferior pancreaticoduodenal the ileocolic the intestinal. It is a rare disorder that results in compression of the vessel.

Superior mesenteric artery syndrome also known as wilkies syndrome 1 cast syndrome or aortomesenteric syndrome is a digestive condition that occurs when the duodenum the first part of the small intestine is compressed between two arteries the aorta and the superior mesenteric artery. This includes the lower duodenum as well as transverse colon. The third part of the duodenum a segment of the small intestines.

The superior mesenteric artery is the second of the three major anterior branches of the abdominal aorta the other two are the coeliac trunk and inferior mesenteric artery. The superior mesenteric arterys initial course is forwards and downwards and it travels posterior to the neck of the pancreas and the splenic vein. Single vessel arising anteriorly from the abdominal aorta at the level of l1 usually just below the celiac trunk.

Located under this portion of the superior mesenteric artery between it and the aorta are the following. Uncinate process of pancreas this is a. It arises anteriorly from the abdominal aorta at the level of the l1 vertebrae immediately inferior to the origin of the coeliac trunk.

Superior mesenteric artery syndrome is also known as wilkie syndrome. The superior mesenteric artery is usually found running to the left side of the superior mesenteric vein which drains the same region as the artery supplies. It is believed that there is an acute angulation of the superior mesenteric artery which results in compression between the third part of the duodenum and the abdominal aorta.
