Where is the marginal artery

Elevated serum lactate may be found due to bowel ischemia. Emergent CT Angiogram of the abdomen is indicated if one suspects acute mesenteric ischemia. Treatment options for acute thrombosis include open surgery, percutaneous angioplasty, and stenting or thrombolytic therapy. The condition carries very high mortality if there is a delay in treatment. Nonocclusive mesenteric ischemia results in decreased perfusion of the bowel. It may be due to septic shock, a myocardial infarct, hypovolemia, or the use of high doses of vasopressors which can cause vasoconstriction.

The marginal artery, also known as the artery of Drummond, supplies the proximal descending colon at the splenic flexure. The artery of Drummond is an arterial arcade formed by an anastomosis between the distal branches of the superior and inferior mesenteric arteries.

This anastomosis is often weak and tortuous, or may even be absent. Thus the splenic flexure is a watershed area that is prone to ischemia and infarction in the setting of hypoperfusion.

Sudden occlusion of the superior mesenteric artery causes acute mesenteric ischemia, a surgical emergency that carries a high mortality rate. The left renal vein can be compressed between the angle formed by the superior mesenteric artery and the abdominal aorta, resulting in nutcracker syndrome.

Symptoms may include hematuria, abdominal pain, and left testicular pain in men or left lower quadrant pain in women. These symptoms are due to the occlusion of the left gonadal vein, which drains into the left renal vein.

Superior mesenteric artery syndrome occurs when the third and fourth portions of the duodenum become compressed between the abdominal aorta and the superior mesenteric artery.

Its symptoms include early satiety, nausea, vomiting, and sharp postprandial abdominal pain due to small bowel obstruction. Superior mesenteric artery syndrome, also known as Wilkie syndrome, is a rare disorder that results in compression of the vessel. 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.

The syndrome is known to occur in patients with low body weight, most notably young children. Dissection of the superior mesenteric artery is a rare, but severe condition that has been reported. It presents with severe abdominal pain and bloody diarrhea and is often confused with acute mesenteric ischemia.

It is most commonly found on CT angiogram of the abdomen. There is no consensus opinion on the ideal management of superior mesenteric artery dissection.
