Pseudoaneurysm after foot surgery.

Pseudoaneurysm (PA) is recognized as a rare complication after pediatric foot surgery. We identified the incidence, pertinent clinical features, and response to surgical intervention in PA as a complication of foot surgery. Four PAs were identified after 2,756 foot operations, an overall incidence of 0.14%. These patients typically had symptoms between 2 and 3 months after index operation with an enlarging, pulsatile, compressible mass in the plantar medial aspect of the foot. Arteriography was helpful in planning surgical intervention. Operative treatment consisted of ligation and excision of PA in all patients. Final outcome of foot deformity surgery was not compromised.
