Angiographic spectrum in Crohn's disease of the small intestine and colon

Barium and angiographic examinations of the small intestine and colon were performed in 34 patients with histopathologically verified Crohn's disease. The spectrum of angiographic findings varied from hypervascularity with no morphologic changes of the vasa recta to complete obstruction of the vasa recta resulting in hypovascularity of the diseased intestine. A distinctive angiographic pattern was present in the distal part of the small intestine in those patients with advanced narrowing of the intestinal lumen as demonstrated on barium examination.
