Cystic myxomatous degeneration

Cystic myxomatous degeneration

This is typified by an accumulation of clear jelly (like a synovial ganglion) in the outer layers of a main artery , especially the popliteal artery . The lesion may narrow the vessel, causing claudication. Duplex scan is the investigation of choice. Decompression, by removal of the myxomatous material, may be successful but in some cases excision of the diseased artery with interposition vein graft repair is required.
