[Ruptured popliteal aneurysm].
A 56-year-old man with Down's syndrome and a known popliteal aneurysm 6 cm in diameter was seen with a huge distal femoral mass which had been present for about two months. At operation, the original thrombus from a ruptured aneurysm was enucleated, the aneurysm excluded, and a femoropopliteal in situ bypass performed. At twelve months follow-up, the patient presented with a foot pulse and an unchanged peroneal nerve deficit.
