Angiographic diagnosis of small intestinal intussusception.
The outstanding angiographic features of small intestinal intussusception are: (a) abrupt disappearance of mesenteric vessels at the neck of the intussusception with crowding of the vasa recta; (b) appearance of long collateral channels at the neck of intussusception; (c) angulation and retraction of major intestinal branches; (d) reversal of the course and angulation of the invaginated mesenteric vessels; (e) overlapping of the mesentery vessels by branches of the intussuscipiens; (f) abrupt change in the appearance of the vasa rectae of the distended intussuscipiens and the distal nondistended small intestines.
