FD American Society of Neuroradiology SP 1942 OP 1945 VO 16 IS 9 A1 M Komiyama A1 T Yasui A1 T Izumi YR 1995 UL http://www.ajnr.org/content/16/9/1942.abstract AB Transient involuntary movement of the leg developed during diagnostic or therapeutic angiography in five patients. The movement was jerky, brisk flexion/extension of the hip and knee joints on the side contralateral to acute ischemia. This movement may occur as a result of thromboembolic cerebral ischemia or as an ischemic complication of angiography.
