What is superior mesentery?

The superior mesenteric artery is in the midsection of the digestive tract (midgut). It originates from the aorta between the celiac artery and renal arteries. The celiac artery supplies blood to the liver, spleen and stomach. The renal arteries send blood to the kidneys.

What is a gastroduodenal artery aneurysm?

Gastroduodenal artery (GDA) aneurysm is a rare but potentially fatal vascular disease, with chronic pancreatitis being reported as the commonest aetiological factor. Its main complication is rupture, which is not uncommon and carries high risk of mortality.

What is a gastroduodenal artery embolization?

Abstract. The gastroduodenal artery (GDA) is frequently embolized in cases of upper GI bleed that has failed endoscopic therapy. Additionally, it may be done for GDA pseudoaneurysms or as an adjunctive procedure prior to Yttrim-90 (Y90) treatment of hepatic tumors.

What is gastroduodenal a branch of?

The gastroduodenal artery arising from the common hepatic artery, a branch of the celiac trunk, becomes the superior pancreaticoduodenal artery as it passes behind the first portion of the duodenum. The superior pancreaticoduodenal artery branches into the anterior and posterior superior pancreaticoduodenal arteries.

What is a GDA pseudoaneurysm?

Gastroduodenal artery pseudoaneurysm rupture is a rare, life-threatening condition, and bleeding into the gastrointestinal tract is the most rapidly fatal complication of an arterial visceral pseudoaneurysm.

What does embolization treat?

Embolization may be used to stop bleeding or to block the flow of blood to a tumor or abnormal area of tissue. It may be used to treat some types of liver cancer, kidney cancer, and neuroendocrine tumors. It may also be used to treat uterine fibroids, aneurysms, and other conditions.

Is there a role for empiric gastroduodenal artery embolization in the management of patients with active upper GI hemorrhage?

Empiric embolization of the GDA in patients with major upper gastrointestinal hemorrhage refractory to endoscopic treatment appears to be a safe and effective treatment, with low reintervention rates and good clinical outcome comparable to patients where the site of hemorrhage is localized and embolized with computed …

What is the origin of the gastroduodenal?

The gastroduodenal artery arises from the common hepatic artery posterosuperior to the upper border of the superior part of the duodenum. It courses inferiorly behind the duodenum and terminates at its lower border, where it divides into its terminal branches.

How do you treat SMAS?

Acute treatment of SMAS involves gastric decompression and initiation of fluid resuscitation while maintaining appropriate electrolyte balance. Once the patient is stabilized, initiation of nutritional support and rehabilitation may begin.

Is embolization a surgery?

Endovascular embolization (EE) is an invasive surgical procedure. It’s used to treat abnormal blood vessels found in your brain, as well as other areas of your body. This procedure is an alternative to open surgery. It blocks blood vessels to cut off blood flow to an affected area.

What is empiric embolization?

Empiric TAE is defined as embolization without angiographic proof of extravasation or pseudoaneurysm.
