The patient underwent a resection of the cystic common femoral vein lesion and subsequent venous reconstruction.
Histology:
Left common femoral vein: The sections show a large vein. Focal myxoid degeneration of the adventitia seen. Haemosiderin deposition and focal occasional stromal giant cell is seen adjacent to this focus. No other significant pathological features noted. The histological changes present would be compatible with the clinical impression of cystic adventitial disease of the common femoral vein.
