What is anastomosis in anatomy

Synonyms: IMA, Arteria mesenterica caudalis The inferior mesenteric artery arises from the abdominal aorta at the level of the third lumbar vertebra. It supplies the hindgut and has four major branches called The bowel develops in three separate sections, namely the foregut, midgut and hindgut. Separate nerves, arteries, and veins supply these various sections.

It arises from the abdominal aorta, and supplies many of the gastrointestinal viscera. In this article, we shall look at the anatomy of the coeliac trunk – its anatomical position, branches, anastomoses, and clinical relevance. Major Branches After emerging from the aorta, the coeliac trunk extends approximately 1cm before dividing into three major branches – left gastric, splenic and common hepatic arteries. Of these branches, two go left and one goes to the right-hand side. Collectively, they are the major arterial supply to the stomach, spleen, liver, gall bladder, abdominal oesophagus, pancreas and duodenum. Left Gastric Artery The left gastric artery is the smallest of the three branches. It ascends across the diaphragm, giving rise to oesophageal branches, before continuing anteriorly along the lesser curvature of the By Fig 1 – The major branches of the coeliac trunk. Splenic Artery The splenic artery arises from the coeliac trunk just inferior to the left gastric artery. It then travels left towards the splenorenal ligament. It terminates into five branches which supply the segments of the spleen. In addition to supplying t...

A natural communication between two blood vessels or other tubular structures. Example: the long posterior ciliary artery divides into two branches as it enters the posterior part of the ciliary muscle and at its anterior end these branches anastomose with each other and with the anterior ciliary arteries to form the major arterial circle of the iris.

Marginal artery of Drummond (arteria marginalis coli) The marginal artery of Drummond, also known as the marginal arcade, is an anastomotic arterial channel that supplies the entirety of the juxtacolic artery. The marginal artery of Drummond is formed by the anastomosing terminal branches of the arcade of Riolan, which is a portion of the marginal artery of Drummond formed between the right side of the transverse colon and the upper descending Key facts about the marginal artery of Drummond Origin Ileocolic, right colic, middle colic, left colic and sigmoid arteries Branches Vasa recta Supply Large intestine This article will discuss the Synonyms: Juxtacolic artery, Marginal arcade , The marginal artery of Drummond is formed by the anastomotic branches of the ileocolic, right colic, and The arcade of the Riolan refers to the portion of the marginal artery of Drummond that is formed between the branches of the middle and left colic artery. It signifies the site of direct communication between the superior and inferior mesenteric arteries, found in the mesentery between the right side of the transverse colon and the proximal part of the descending colon. This connection is clinically significant to provide collateral blood flow in the event of a stenosis or occlusion. Branches and supply The marginal artery of Drummond gives off numerous small branches called straight arteries, or vasa recta, that supply blood to the large intestine.

Synonyms: Transverse scapular artery, Arteria transversa scapulae Throughout the body, there are several points at which blood vessels unite. The junctions are termed anastomoses. In the simplest sense, an anastomosis is any connection (made surgically or occurring naturally) between tube-like structures. Naturally occurring arterial anastomoses provide an alternative blood supply to target areas in cases where the primary arterial pathway is obstructed. They are most abundant in regions of the body where the blood supply may can be easily damaged or blocked (such as the joints or Key facts Scapular and shoulder anastomoses Suprascapular artery dorsal scapular arteries Acromial branches of thoraco-acromial artery acromial branches of the circumflex humeral and dorsal scapular arteries Posterior circumflex humeral artery anterior circumflex humeral artery Posterior circumflex humeral artery anterior circumflex humeral artery Elbow anastomoses Radial collateral artery middle collateral, recurrent interosseous, and posterior branch of the inferior ulnar collateral arteries Radial recurrent artery radial collateral artery Inferior ulnar collateral artery Anterior ulnar collateral artery Posterior ulnar collateral artery Superior ulnar collateral artery Posterior ulnar recurrent artery posterior branch of the inferior ulnar collateral artery Mnemonic: I Am Pretty Smart Wrist and hand anastomoses Anterior interosseous artery posterior interosseous artery Deep and sup...

An intestinal anastomosis is the opening between two parts of the gastrointestinal tract. Surgeons must sometimes remove diseased parts and reconnect the healthy parts with an opening for food to pass through. An anastomosis is a medical term used to describe connection or opening between two organs or tissues. When a part of the small or Why is intestinal anastomosis done? The intestinal anastomosis is performed following the surgical removal of part of the intestine due to intestinal diseases ore • Intestinal • • Benign tumors (e.g., intestinal polyps, • Infections • Perforations due to infection, ulcers or • Damage to the intestine due to • Complications with bleeding, stricture or perforation • • Scarring and adhesions causing the intestinal block • Chronic • Birth defects of the intestine (e.g. Meckel’s Intestinal resection and anastomosis are performed during the same procedure. The procedure may be done in adults and children. When to avoid intestinal anastomosis The intestinal anastomosis may not be feasible in conditions with a high risk of anastomotic leakage. In such cases, the surgeon may advise alternative techniques. The intestinal anastomosis is avoided in patients with the following conditions: • Severe • Poor nutritional status • • Questionable viability of the intestine • Fecal contamination or infection in the abdomen • Unhealthy and diseased intestine What are the three types of intestinal anastomosis?

• 1 Systemic Venous System • 1.1 Inferior Vena Cava • 2 Portal Venous System • 2.1 Splenic Vein • 2.2 Superior Mesenteric Vein • 3 Clinical Relevance – Porto-Systemic Anastomoses There are two venous systems that drain abdominal structures – the portal venous system and the systemic venous system. The portal system transports venous blood to the liver for processing, whilst the systemic venous system returns blood to the right atrium of the heart. In this article, we shall consider the anatomy of these two venous systems – the major vessels involved, their anatomical course, and their tributaries. Systemic Venous System The systemic venous system transports deoxygenated blood to the right atrium of the heart. The major vessel in this system is the inferior vena cava. Inferior Vena Cava The inferior vena cava is the common convergence of venous drainage from all structures below the diaphragm. It is located on the posterior abdominal wall; anteriorly to the vertebral column and to the right of the abdominal aorta. The vessel is formed by the union of the common iliac veins at the L5 vertebral level. It ascends superiorly, and leaves the abdomen by piercing the central tendon of the diaphragm at the T8 level (the caval hiatus). Within the thorax, the inferior vena cava drains into the right atrium of the heart. During its long course, the inferior vena cava shares an anatomical relationship with numerous abdominal structures – including the right common iliac artery, the roo...
