She guided her finger onto the hole that had been ripped in the superior mesenteric vein.

The ileal veins are tributaries of the superior mesenteric vein.

It drains into the superior mesenteric vein.

Ultimately these veins drain into the portal system, either directly or indirectly through the splenic or superior mesenteric vein.

The right colic vein drains the ascending colon, and is a tributary of the superior mesenteric vein.

The SMA typically runs to the left of the similarly named vein, the superior mesenteric vein.

The superior mesenteric vein drains blood from the small intestine, large intestine, stomach, pancreas and appendix.

Thrombosis of the superior mesenteric vein is quite rare, but a significant cause of mesenteric ischemia and can be fatal.

It is a tributary of the superior mesenteric vein, and follows the path of its corresponding artery, the middle colic artery.

In most individuals, the hepatic portal vein is formed by the union of the superior mesenteric vein and the splenic vein.

The persistent part of the upper venous ring, above the opening of the superior mesenteric vein, forms the trunk of the portal vein.

The Superior mesenteric vessels are composed of the superior mesenteric artery and the superior mesenteric vein.

At its termination behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the hepatic portal vein.

It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).

In anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum).

It joins with the superior mesenteric vein, to form the hepatic portal vein and follows a course superior to the pancreas, alongside of the similarly named artery, the splenic artery.

The uncinate process, unlike the remainder of the organ, passes posteriorly to the superior mesenteric vein (it can pass posteriorly to the superior mesenteric artery, but this is less common).

A stiff guidewire was then passed through the transjugular biopsy needle into the superior mesenteric vein (Fig 1), the needle removed, and a catheter introduced over the wire into the portal vein.

The portal vein is formed by the union of the superior mesenteric vein and the splenic vein posterior to the neck of the pancreas at the level of vertebra body LII.

It collects branches from the stomach and pancreas and most notably from the large intestine (inferior mesenteric vein), which is drained by the superior mesenteric vein and joins with splenic vein shortly before it forms the portal vein.

The superior mesenteric artery passes down in front of the left half across the uncinate process; the superior mesenteric vein runs upward on the right side of the artery and, behind the neck, joins with the lienal vein to form the portal vein.

Venous drainage usually mirrors colonic arterial supply, with the inferior mesenteric vein draining into the splenic vein, and the superior mesenteric vein joining the splenic vein to form the hepatic portal vein that then enters the liver.

A Carrel patch of donor aorta was anastomomosed to an anterior incision in the infrarenal recipient aorta, and the portal vein draining the superior mesenteric vein of the graft was anastomosed end-to-side to the anterior wall of the recipient inferior vena cava.

In contrast to the drainage of midgut and hindgut structures by the superior mesenteric vein and inferior mesenteric vein respectively, venous return from the coeliac artery is through either the splenic vein emptying into the hepatic portal vein or via smaller tributaries of the portal venous system.
