Background: Great saphenous vein (GSV) graft is commonly used for peripheral arterial reconstructions. Pseudo-aneurysm of GSV graft is a rare entity. It can be associated with high morbidity and can be prevented by technical modifications. We hereby report pseudo-aneurysm of  great saphenous vein (GSV) graft. Case Report: Our patient underwent femoro-popliteal bypass surgery after excision of degenerative pseudo-aneurysm of the left superficial femoral artery one month ago. The vein graft tear following aneurysmal rupture was patched up with polytetrafluoroethylene  (PTFE) patch. Patient had his limb saved by a repaired vein graft. We are highlighting the clinical pictures of this rare entity and also describing the management options for it. Conclusion: With early diagnosis and intervention, potentially dangerous and rare clinical condition like GSV graft pseudo-aneurysm can be tackled with good result.
