Anatomical terminology

The right colic vein drains the ascending colon, and is a tributary of the superior mesenteric vein. It travels with its corresponding artery, the right colic artery.

Contents

Background

This study was designed to describe the precise anatomic venous tributaries of the superior mesenteric vein with special emphasis on the superior right colic vein (SRCV), which is seldom mentioned in the literature.

Methods

Nine adult cadavers were dissected to define the venous tributaries of the superior mesenteric vein. The SRCV, middle colic vein, and right colic vein (RCV) were defined as those that drained from the marginal vein of the right flexure of the colon, the transverse colon, and the ascending colon, respectively.

Results

The SRCV was observed to drain from the right flexure of the colon to the confluence of the right gastroepiploic and superior pancreaticoduodenal veins and present the gastrocolic trunk of Henle (GTH) in 8 of 9 cases. The RCV terminated into the GTH in 4 cases. The SRCV, the RCV, and the middle colic vein formed a confluence and entered into the GTH in 1 case.

Conclusions

The SRCV exits and drains from the right colonic flexure to the GTH in 89% of cases.

<span class="mw-page-title-main">Large intestine</span> Last part of the digestive system in vertebrates

The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system in tetrapods. Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation. The colon is the longest portion of the large intestine, and the terms are often used interchangeably but most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal. Some other sources exclude the anal canal.

<span class="mw-page-title-main">Portal vein</span> Short thick vein formed by the union of the superior mesenteric vein and the splenic vein

The portal vein or hepatic portal vein (HPV) is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. This blood contains nutrients and toxins extracted from digested contents. Approximately 75% of total liver blood flow is through the portal vein, with the remainder coming from the hepatic artery proper. The blood leaves the liver to the heart in the hepatic veins.

<span class="mw-page-title-main">Mesentery</span> Contiguous fold of tissues that supports the intestines

In human anatomy, the mesentery, an organ that attaches the intestines to the posterior abdominal wall, comprises the double fold of the peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines.

In human anatomy, the abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of the descending aorta.

<span class="mw-page-title-main">Superior mesenteric artery</span> Artery which supplies blood to the intestines and pancreas

In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.

The Kocher manoeuvre is a surgical procedure to expose structures in the retroperitoneum behind the duodenum and pancreas. In vascular surgery, it is described as a method to expose the abdominal aorta. It usually has been in contrast to midline laparotomy and right retroperitoneal space dissection. These two procedures have been used for diverse cases, but have approximately equivalent outcomes.

<span class="mw-page-title-main">Inferior mesenteric artery</span>

In human anatomy, the inferior mesenteric artery (IMA) is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal. The regions supplied by the IMA are the descending colon, the sigmoid colon, and part of the rectum.

<span class="mw-page-title-main">Superior mesenteric vein</span> Vein which drains blood from the small intestine

In human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine. Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the portal vein that carries blood to the liver. The superior mesenteric vein lies to the right of the similarly named artery, the superior mesenteric artery, which originates from the abdominal aorta.

<span class="mw-page-title-main">Marginal artery of the colon</span> Human artery

In human anatomy, the marginal artery of the colon, also known as the marginal artery of Drummond, the artery of Drummond, and simply as the marginal artery, is an artery that connects the inferior mesenteric artery with the superior mesenteric artery. It is sometimes absent, as an anatomical variant.

<span class="mw-page-title-main">Inferior mesenteric vein</span> Vein which drains blood from the large intestine

In human anatomy, the inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).

<span class="mw-page-title-main">Right colic artery</span> Artery supplying the colon

The right colic artery is an artery of the abdomen, a branch of the superior mesenteric artery supplying the ascending colon. It divides into two terminal branches - an ascending branch and a descending branch - which form anastomoses with the middle colic artery, and ileocolic artery (respectively).

<span class="mw-page-title-main">Middle colic artery</span> Artery supplying the colon

The middle colic artery is an artery of the abdomen; a branch of the superior mesenteric artery distributed to parts of the ascending and transverse colon. It usually divides into two terminal branches - a left one and a right one - which go on to form anastomoses with the left colic artery, and right colic artery (respectively), thus participating in the formation of the marginal artery of the colon.

<span class="mw-page-title-main">Left colic artery</span> Artery

The left colic artery is a branch of the inferior mesenteric artery distributed to the descending colon, and left part of the transverse colon. It ends by dividing into an ascending branch and a descending branch; the terminal branches of the two branches go on to form anastomoses with the middle colic artery, and a sigmoid artery (respectively).

<span class="mw-page-title-main">Colic flexures</span> Two abrupt bends in the large intestine

In the anatomy of the human digestive tract, there are two colic flexures, or curvatures in the transverse colon. The right colic flexure is also known as the hepatic flexure, and the left colic flexure is also known as the splenic flexure. Note that "right" refers to the patient's anatomical right, which may be depicted on the left of a diagram.

<span class="mw-page-title-main">Midgut</span> Embryonic structure from which most of the human intestines develop

The midgut is the portion of the human embryo from which most of the intestines develop. After it bends around the superior mesenteric artery, it is called the "midgut loop". It comprises the portion of the alimentary canal from the end of the foregut at the opening of the bile duct to the hindgut, about two-thirds of the way through the transverse colon.

<span class="mw-page-title-main">Middle colic vein</span>

The middle colic vein drains the transverse colon. It is a tributary of the superior mesenteric vein, and follows the path of its corresponding artery, the middle colic artery. As the superior mesenteric vein drains to the hepatic portal vein, the middle colic vein is considered part of the hepatic portal system. This vein also carries nutrients absorbed from the large intestine to the liver.

<span class="mw-page-title-main">Left colic vein</span>

The left colic vein is a vein that drains the left colic flexure and descending colon. It empties into the inferior mesenteric vein. It accompanies the left colic artery.

In the circulatory system of vertebrates, a portal venous system occurs when a capillary bed pools into another capillary bed through veins, without first going through the heart. Both capillary beds and the blood vessels that connect them are considered part of the portal venous system.
