· Thickness : 1 inch · Breadth: 3 inches · Length: 5 inches.
· Weight: 7 Ounces ·Extends from 9 th to 11th rib.
Ä Posteriorly The spleen is in contact with the diaphragm,
Ä Anteromedialy, the stomach
Ä Posteromedialy the left kidney
Ä Inferiorly the spienic flexure of the colon.
The inferior pole of the spleen is supported by a weak avascular ligament called the phrenicocolic ligament. When the spleen enlarges, this ligament yields under its weight. It is presumed that in cases of bilharziasis, this ligament is fibrosed and becomes tense, so it can direct the enlarged organ medially toward the umbilicus.
m Blood Supply:
· The splenic artery comes from the coeliac axis and it gives three to, five branches in the hilum of the spleen. It also gives the short gastric vessels and the left gastroepiploic artery to the greater curvature of the stomach.
· The splenic vein receives the inferior mesenteric vein and then joins the superior mesenteric vein to form the portal vein.
m Surface landmarks
· The upper border is in level with the 9th rib, the lower border is in level with the 11th rib.
· This lateral (anterior) pole is in the midaxillary line, the medial (posterior) pole is in the posterior scapular line.
· The upper border is characterized by the presence of a notch which becomes prominent on enlargement and is a good mark of identification of splenic enlargement.
