Dorsalis Pedis Artery Pseudoaneurysm

Abstract

SUMMARY:
An unusual case report is described here, of a young man who developed a pseud oaneurysm of the left Dorsalis Pedis Artery (DPA) ten years earlk?r, following a blunt injury. He sustained a recent injury to the same foot following which, the lump became enlarged and painful. Doppler flow studies and angiography confirmed the diagnosis and revealed the causative ostium through which this partially thrombosed aneurysm had arisen. Successful aneurysmectomy and end-to-end LSV bypass graft surgery was followed by complete recovery.

Discussion:

This patient’s aneurysm was partially thrombosed. A properly performed real time B mode Ultrasound scan can reliably show intrinsic thrombi, the thickness of the aneurysm a! wall and the diameter of the functional lumen (1).Vigorous manual compression of an aneurysm may dislodge intrinsic thrombi distally (3). Traditional demonstration of the “sign of compressibility” should be superseded by non-invasive doppler assessment.Our patient was in pain most certainly due to a variety of reasons. Compressive neuropathy (18), distension of the deep fascia, irritation of the muscle sheath, movement of the aneurysm due to contraction of the involved and adherent muscles etc., can all have been the causes of this local pain.
