Spontaneous giant popliteal artery aneurysm

Abstract

A 60 year old male presented with sudden onset of pain in right lower limb, difficulty in standing and antalgic gait since 3 days. There was no history of trauma. Examination showed a non-tender, compressible, pulsatile 10 x 6 cm swelling in the right popliteal fossa. His blood investigations were within normal range. Arterial duplex ultrasonography of right lower limb showed right sided popliteal artery aneurysm (PAA) with foci of thrombus in it. CT-angiography confirmed the findings. He underwent popliteal artery aneurysmectomy and interposition of graft. He was discharged on postoperative day 5. We will be describing a case of spontaneous giant PAA and discuss the protocol that we follow.
