ligament of Treitz
It is often used interchangeably with duodenojejunal flexure.
The ligament of Treitz comprises two parts:
- descends from connective tissue of celiac artery to the duodenojejunal flexure, between the pancreas and the left renal vein
- this is the part that suspends the duodenojejunal flexure
- composed of smooth muscle
The ligament of Treitz is a landmark:
- for the radiological diagnosis of intestinal malrotation and partial rotation
- for discriminating between upper and lower gastrointestinal bleeding
Congenital superior mesenteric artery syndrome can be caused by a short ligament of Treitz.
In adults, the ligament often involutes or is entirely absent. Hence, it is virtually impossible to image . Its location can be inferred from its anatomical relations (see duodenojejunal flexure).
History and etymology
It is named after Czech pathologist Václav Treitz, who described it in 1853, referring to it as the "suspensory muscle of the duodenum".
