The superior mesenteric artery and the variations of the colic patterns. A new anatomical and radiological classification of the colic arteries.

The superior mesenteric artery (SMA) supplies irrigation to the small intestine, ascending and a variable area of the transverse colon. Although medical imaging and surgical procedures have been widely developed in the last decades, the anatomy of the SMA using advanced imaging technology remains to be elucidated. Previous studies have used small sample sizes of cadaveric or radiological samples to propose a number of classifications for the SMA.

Syndrome of Alagille: radiological and sonographic findings. A review of 37 cases.
