ABSTRACT

Adventitial cystic disease (ACD) was rst discovered by Atkins in 1947 in a case report describing its involvement with the external iliac artery.1 Ejrup and Hiertonn, in Stockholm, Sweden, rst described this clinical entity of the popliteal artery in 1954.2 Hiertonn, with coauthors Lindberg and Rob, produced a subsequent publication, which described cystic degeneration of the popliteal artery.3 ey reviewed four known cases encountered up to 1957. A number of valuable descriptive terms were applied to the lesion including ‘clear, jelly-like material similar in appearance to that seen in a ganglion’, ‘the specimen looked like a sausage and was 7 cm in length’ and ‘the lumen was compressed by an intramural cyst containing jelly under high tension’.
