Arterial cystic degeneration.

Introduction Arterial cystic degeneration as a cause of symptomatic peripheral vascular disease is uncommon. The most frequently reported site is the popliteal artery, the first description of which was reported in Scandinavia by Ejrup & Hiertonn in 1954, and in Great Britain by Hiertonn, Lindberg & Rob in 1957. Further cases of the disorder affecting the popliteal artery have been reported frequently since then (Table 1), but other arteries appear to be involved only rarely. This paper records two further cases of arterial cystic degeneration, one affecting the popliteal artery, the other involving the iliac artery.
