End arteries are arteries that do not anastomose with neighboring arteries except through terminal capillaries. Obstruction of such an artery is likely to lead to local death, resulting in the case (a) of a cerebral artery, in paralysis, (b) of the central artery to the retina, in blindness, (c) of a branch of the renal or splenic artery, in death of a segment of the kidney or spleen, (d) of two or three adjacent vasa recta of the gut, in gangrene of the gut, and for the artery to the appendix.
