title: Vascular anatomy: how to identify the major retroperitoneal vessels.
abstract: The anatomical relationships of retroperitoneal vessels and organs as seen from the stomach and duodenum with sector scan and linear array echoendoscopes are discussed. Methods to place and maneuver the echoendoscope in six standard, easily recognized positions and the withdrawn-wedged position are reviewed. From these positions, major retroperitoneal vessels can be investigated.
