The left gastric artery is the principal blood supply to the stomach after sleeve gastrectomy and it gives off many posterior branches which should remain uninterrupted during dissection of the posterior surface of the stomach. These small branches penetrate into the vertebral bone through small openings such as the intervertebral foramina. [1] This is an uncommon medical condition, but it has a high mortality rate. Compared to other vessels of similar size, the SMA is largely spared from the effects of atherosclerosis. It typically arises from a left posterior intercostal artery at the level of the 9th to 12th intercostal artery, which branches from the aorta, and supplies the lower two-thirds of the spinal cord via the anterior spinal artery. Three main arteries, called the mesenteric arteries, supply blood to your small and large intestines. Narrowing or blockage in these arteries reduces the amount of blood that travels to your digestive tract. The membranous labyrinth is supplied by the labyrinthine artery, a branch of the inferior cerebellar artery (or, occasionally, the basilar artery). The first line of treatment for superior mesenteric artery syndrome is nonsurgical management that includes: People with superior mesenteric artery syndrome may be advised to eat very small meals. Good nutrition helps to boost the mesenteric fat pad. That may improve the symptoms of superior mesenteric artery syndrome. Abstract. A : lumen. D : right subclavian artery. The inferior epigastric artery arises from the external iliac artery, immediately above the inguinal ligament.

The superior mesenteric artery (SMA) is one of the three non-paired major splanchnic arteries in the abdominal cavity arising from the abdominal aorta and supplying the midgut. The ovarian arteries are paired structures that arise from the abdominal aorta, usually at the level of L2.After emerging from the aorta, the artery travels down the suspensory ligament of the ovary, enters the mesovarium, and may anastamose with the uterine artery in the broad ligament. What is the most common indication for mesenteric artery duplex evaluation? C : left subclavian artery. This artery is completed by branches of the left colic which is a branch of the inferior mesenteric artery. This may be due to protective haemodynamic conditions. This branch ascends between the internal oblique muscle and the transversus abdominis muscle, supplying them, and anastomosing with the lumbar arteries and inferior epigastric artery. The term extra renal artery may be used 6, with a c. chronic mesenteric ischemia.
