A 70 yr old male presented to the department of Cardiovascular Radiology and Endovascular Interventions, All India Institute of Medical Sciences, New Delhi, India, in October 2019, with a gradually progressive swelling of the lower left limb over the past five years accompanied by dull-aching pain on walking. Clinical examination revealed skin discolouration and superficial varicosities along the left thigh and leg [Figure 1]A with a thrill in the left inguinal region and upper thigh with positive  Nicoladoni-Branham sign More Details. On enquiry, the patient gave a history of gunshot wound to the left thigh 37 years back.

Computed tomography angiography demonstrated fistulous communication between the left superficial femoral artery and vein in the lower third of the thigh with aneurysmally dilated and extremely tortuous iliac and femoral arteries and veins as well as superficial varicosities [Figure 1]B and [Figure 1]C. The retained bullet fragments were also seen adjacent to the fistula [Figure 1]D. As lesion morphology was unsuitable for endovascular management, the patient was advised for possible surgical intervention; however, the patient did not opt for the same.

Penetrating trauma (including stab and gunshot wounds) is an important cause of acquired arteriovenous fistula; however, delayed presentation after more than three decades is rare. Protracted escalation in the blood flow may result in aneurysmal dilatation of the blood vessels by altering the elastic fibre constitution of their walls.

Conflicts of Interest: None.
