The left angiogram panel 2 (Abb. 2) indicates a high-grade stenosis of the left common iliac artery in a 73-year-old male patient, the procedure was performed on March 6, 1974. Note the differently sized angioplasty balloons, both in diameter and length. The German figure legend indicates that both patients were free of symptoms on follow-up 3 months after the procedure.
