Pseudoaneurysm of the lateral plantar artery after foot laceration.

Two children with lateral plantar artery pseudoaneurysms are presented. Both cases were associated with a plantar laceration and were successfully treated with ligation. Only one other report of a lateral plantar artery pseudoaneurysm was found in the literature; no reports involving the medial plantar artery have been reported. A cadaver dissection supports the hypothesis that the lateral plantar artery is more superficially located and therefore more vulnerable to injury compared with the medial plantar artery. Clinicians treating patients with lacerations of the foot should be aware that an arterial injury may be present, even in the absence of active bleeding.
