Delayed presentation of superficial femoral artery pseudoaneurysm 45 years following gunshot injury

This case report is a description of an uncommon delayed presentation of penetrating trauma of lower limb with history of inciting event being 45 years ago, as there are only 4 such reported cases in the literature. A 65-year-old male presented with progressive enlargement of swelling over the anterior aspect of the right thigh with difficulty in walking due to mechanical effects and paraesthesia in the affected limb. Clinical signs of a large lump in the right anteromedial thigh with no pulsations were present. Computerised tomographic angiography revealed the presence of a superficial femoral artery pseudoaneurysm. The open surgical management involved resection of the pseudoaneurysm and autologous vein patch angioplasty. The rarity of incidence and paucity of physical signs suggest that a high index of suspicion, careful clinical review and radiological investigation is indispensable to diagnose and treat this condition.
