Splenic infarction is a condition in which blood flow supply to the spleen is compromised, [1] leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ. [2] Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot. [3]
In human anatomy, the splenic artery or lienal artery, an older term, is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas. It is known for its tortuous path to the spleen.
The spleen (from Anglo-Norman espleen, ult. from Ancient Greek σπλήν, splḗn) [1] is an organ found in almost all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter. The spleen plays important roles in regard to red blood cells (erythrocytes) and the immune system. [2]
The trabecular arteries are the name of the branches of the splenic artery after it passes into the trabeculae of the spleen, where it branches.When these arteries then reach the white pulp, and become covered with periarteriolar lymphoid sheaths, the name changes again to central arteries (or central arterioles).
Functional end arteries supply segments of the brain, liver, kidneys, spleen and intestines; they may also exist in the heart. Occlusion of an end artery causes serious nutritional disturbances resulting in death of the tissue supplied by it. For example, occlusion of central artery of retina results in blindness.
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply. [5] The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque ...

The basic pathology is some kind of obstructive pathology in the portal, hepatic or splenic vein that causes obstruction of venous blood flow from the spleen towards the heart. The cause of such obstruction may be abnormalities present at birth (congenital) of certain veins, blood clots, or various underlying disorders causing inflammation and ...
