[Ultrasonic topographical study of pancreatic vascular relationships; I. Splenic vein, SMA, SMV, celiac trunk (author's transl)].

Sonography, a "dissection on the living patient", displays many topographical variations, of whom several are usually not depicted in classical textbooks of anatomy. Sonographic and angiographic studies disclosed the following results: the splenic vein is running above the AMs origin (34%), at the same level (7%), or below (59%). The SMA originates at a distance of 5 to 45 mm of the CT origin. The SMV is running on the right, on the left or in front of the SMA. Such variations must be kept in mind when analysing the morphology and rich vascular relationships of the pancreas.
