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]
Splenomegaly is an enlargement of the spleen. [1] The spleen usually lies in the left upper quadrant (LUQ) of the human abdomen.Splenomegaly is one of the four cardinal signs of hypersplenism which include: some reduction in number of circulating blood cells affecting granulocytes, erythrocytes or platelets in any combination; a compensatory proliferative response in the bone marrow; and the ...
The spleen of each patient was then quantitatively measured using chromium-labeled erythrocytes and radioisotope photoscan of the spleen. Castell showed those patients in the control group had a mean spleen size of 75 cm 2 with a range of 57 cm 2 to 75 cm 2 , while those who had a positive percussion sign had a mean spleen size of 93 cm 2 with ...
Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
In most individuals, the portal vein is formed by the union of the superior mesenteric vein and the splenic vein. [5] For this reason, the portal vein is occasionally called the splenic-mesenteric confluence. [4] Occasionally, the portal vein also directly communicates with the inferior mesenteric vein, although this is highly variable.
An accessory spleen is a small nodule of splenic tissue found apart from the main body of the spleen. ... The typical size is approximately 1 centimeter, but sizes ...
Traube's (semilunar) space is an anatomic space of some clinical importance. It is a crescent-shaped space, encompassed by the lower edge of the left lung, the anterior border of the spleen, the left costal margin and the inferior margin of the left lobe of the liver.
Painless hepatomegaly and splenomegaly: the size of the spleen can be 1,500–3,000 g (3.3–6.6 lb), as opposed to the normal size of 50–200 g (0.11–0.44 lb).). Splenomegaly may decrease the affected individual's capacity for eating by exerting pressure on the s
