A Case of Digital Pseudoaneurysm Following Sharp Injury to a Digit.

Background. A 74-year-old woman presented to the plastic surgery hand trauma clinic with painful, pulsatile swelling in her left index finger following a sharp incision injury to the digit. A diagnosis of digital artery pseudoaneurysm was made. Digital aneurysmal formations are uncommon, and in the upper limb such aneurysms are often secondary to trauma, including iatrogenic injuries. Surgery is usually indicated for symptom relief; if there are signs of compromised perfusion, either direct arterial repair or reconstruction with a vein graft may be required following excision of the aneurysmal sac.
