A penetrating nail-prick injury of the lateral plantar artery leading to pseudo-aneurysm formation and rupture.

ABSTRACT

Pseudo-aneurysm in the plantar region is so rare that there are only sporadic case reports in the literature. The aetiology is usually either iatrogenic or stepping on a piece of glass. In comparison to the medial plantar artery, the lateral plantar artery is the most common arterial structure injured in the plantar region due to its more superficial course and it being less protected by the surrounding structures. With variable presentation and different time intervals from injury to diagnosis, the mechanism and penetration depth of the injury is thought to have a major impact on the formation of a pseudo-aneurysm. The aims of this article were to present a case of a lateral plantar artery injury after stepping on a construction nail, leading to pseudo-aneurysm formation and rupture, and to review the literature with regard to the clinical characteristics of these rare and overlooked cases.
