The second part of the ligament of Treitz is a thin muscular band originating from the celiac trunk as a connective tissue band. It passes between the splenic vein, left renal vein and the pancreas to insert at the duodenojejunal flexure (DJ flexure) and part of the inferior aspect of the transverse duodenum.
What is the importance of the ligament of Treitz?
The ligament of Treitz is an anatomical landmark used by anatomists and surgeons to denote the duodenojejunal junction and the point where the small intestine passes from retroperitoneal duodenum to intraperitoneal jeunum.
What vertebral level is the ligament of Treitz?
The ligament most commonly (in 40–60% of cases) attaches to the third and fourth parts of the duodenum and the duodenojejunal flexure at the level of the inferior border of the first lumber vertebra (Fig. 2A).
What does the ligament of Treitz divide?
The anatomic landmark that separates upper and lower bleeds is the ligament of Treitz, also known as the suspensory ligament of the duodenum. This peritoneal structure suspends the duodenojejunal flexure from the retroperitoneum.
Is the ligament of Treitz retroperitoneal?
The ligament of Treitz, also known as the suspensory ligament of the duodenum, is a double fold of peritoneum suspending the duodenojejunal flexure from the retroperitoneum. It is often used interchangeably with duodenojejunal flexure.
What is Treitz angle?
The angle of Treitz is also known as the ligament of Treitz and is the junction of the duodenum and jejunum adjacent to the mesenteric vessels.
