Popliteal artery aneurysms and popliteal phymas.

For the differential diagnosis of popliteal phymas, popliteal artery aneurysms are evaluated. They are frequent among peripheral aneurysms. However, diagnosis is difficult in some patients because clinical symptoms vary. We report 2 patients who consulted our hospital for popliteal phymas. In these patients, surgery was performed via a posterior approach. In 1 patient, reconstruction was conducted using a great saphenous vein graft (SVG). Even when employing the posterior approach, SVG collection and reconstruction are possible without changing the posture for short-distance reconstruction. This procedure may prolong patency in comparison with artificial blood vessels.
