Griffiths point
Updates to Article Attributes
The Griffiths point (orGriffiths critical critical point)refers to the site of watershed anastomosis between the ascending left colic artery and the the marginal artery of Drummond occurring in the region of the splenic flexure. Most anatomy texts describe the location as 2/3rds along the transverse colon.
This represents an important collateral communication between thesuperior mesenteric and inferior mesenteric arteries upon which the splenic splenic flexure and descending colon may be dependent dependent.

Angiography
Angiographic studies show that anastomosis at Griffiths point point is present in 48%, poor or tenuous in 9%, and absent in 43% 1.
