Cattell Braasch Vs Mattox Maneuver

***********************

There are two major surgical methods utilized in order to access the retroperitoneal region, with each approaching from the opposite direction.

• Cattell-Braasch maneuver: A right medial visceral rotation;  is used to expose the entire inframesocolic retroperitoneal organs, including the inferior vena cava (IVC), the right renal pedicle, the right iliac vessels, the duodenum, and the head of the pancreas.
• Mattox Maneuver: A left medial visceral rotation; is performed for exposure of the entire aorta from the diaphragmatic hiatus caudally to the iliac vessels.
