What is splenic embolization?
Splenic (artery) embolization is an endovascular technique for treatment of splenic and splenic artery pathology as an alternative to splenic artery ligation or splenectomy. It often results in successfully treating the underlying pathology, while maintaining at least partial splenic function.
Why is splenic artery coiled?
The placement of coils in a middle segment of the splenic artery allows reconstitution of the blood supply through collateral vessels, principally via the short gastric and gastroepiploic arteries, to the patent distal splenic, transgastric, and transpancreatic arteries.
What is the collateral arterial supply to the spleen?
The short gastric (SG) arteries and left gastroepiploic (LGE) arteries may be the most important part of the collateral blood supply to the spleen. There are also collaterals from the superior mesenteric (SM), pancreatic, and left inferior phrenic (LIP) arteries. (CH = common hepatic artery; LG = left gastric artery.)
Why would your spleen be removed?
The spleen is an organ that sits under your rib cage on the upper left side of your abdomen. It helps fight infection and filters unneeded material, such as old or damaged blood cells, from your blood. The most common reason for splenectomy is to treat a ruptured spleen, which is often caused by an abdominal injury.
Is splenic artery an end artery?
Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.
Why is the splenic artery tortuous?
Splenic artery also called as the lienal artery, is the largest branch of celiac trunk. The difference in the increasing length of the artery and the distance between its origin and the splenic hilum makes the artery tortuous. The proximal part of the artery is more tortuous than the distal part [7].
What does a damaged spleen feel like?
The main symptom of a ruptured spleen is severe pain in the abdomen, especially on the left side. The pain may also be referred to (felt in) the left shoulder, and can make breathing painful. Other symptoms, which are associated with a decrease in blood pressure due to internal bleeding, include: Feeling lightheaded.
