ORIGINAL OBLIQUE SECTIONS OF THE RETROPERITONEUM - RADIO-ANATOMIC BASIS

The authors present oblique sections of the retroperitoneum adapted to the morphology of each patient, which affects both the liver and the organisation of the retroperitoneum. This original method involve two incidences for studying the left and right retroperitoneum separately with vertical sectional planes, The authors postulate that the orienta tion of the retroperitoneal viscera depends on the degree of hepatic d evelopment, so these incidences are chosen with reference to axial sec tions of the portal bifurcation and the middle hepatic v.: the two vas cular landmarks of the liver. Anatomic and radiologic studies confirm the reliability of these landmarks and their easy application in moder n imaging, Such new data improve our understanding of the classical to pographic anatomy of the retroperitoneum, These oblique sections promo te the radiologic study of the portal and systemic vessels, renal pedi cles, suprarenal glands and pancreas.
