He was admitted to this hospital with the chief compliant of marked swelling accompanied with severe pain of the left thigh and the past history of a blunt trauma 7 years ago on the left groin? He had also severe anemia with hb 4.4 g/dl. An aneurysm measuring 15 by 8 cm was detected on the arteriogram. The aneurysm was treated by resection and implantation of Gore-Tex graft with good result. The pathological findings strikingly suggested that the false aneurysm was caused by the old blunt trauma. A false aneurysm of femoral artery caused by a blunt trauma is very rare and it's complications include acute arterial occlusion, subsequent ischemic change of lower limb and massive bleeding by the rupture. In conclusion, early diagnosis and surgical treatment are essential for a false aneurysm of femoral artery.
