Translated title:
The blood supply of the spleen and its significance in surgery
Summary:
The spleen is a compact organ of the reticuloendothelial system, located in the left hypochondrium. Its usual length is 7 to 10 cm. The organ makes its appearance at the fifth week of gestation. Its blood flow comes from the splenic artery and vein, the left gastroepiploic artery and the short gastric arteries and veins. The variants of the spleen formation and of the course and origin of the splenic vessels are often.
The knowledge of the anatomy, embryology and splenic vessel vari-ants are essential for every surgeon. The embryological avascular planes of the left upper quadrant offer the possibility for safe maneuvers and mobilizations in this area. Standard surgical principles are applied on the manipulation of the splenic vessels and the spleen, as far as the spleen itself is concerned, as well as the nearby organs, i.e. the depression of the splenic flexure, the mobilization of the distal pancreas and the mobilization of the stomach. The knowledge of the vascular structures of the spleen, offer the possibility of treatment to patients with splenic artery aneurysms, patients with portal hypertension and gastroesophageal varices and to trauma patients that can nowdays be treated with embolism.
The confirmation that the spleen is viable, even after ligating the splenic artery and vein, led to the development of spleen – preserving techniques, allowing the minimization of the morbidity of the distal pancreatectomy, eliminating the consequences of splenectomy. The results in the current literature, about which spleen – preserving technique should be preferred, are still controvensial. Each surgeon should be familiar with both techniques and surgical treatment should be personalized for every patient.
