Spontaneous rupture of iatrogenic (postinguinal herniorrhaphy) venovenous malformation managed endoscopically

Complications of open inguinal hernia repair, such as wound infection, hematoma, seroma, and neuralgia, are known to occur. Vascular injuries during inguinal hernia repair are rare and documented as case reports only. Vascular malformations are known to occur after trauma or sharp injuries. Most of the venous malformations are congenital in origin and usually reported in relation to congenital heart disease or in visceral locations. We encountered an iatrogenic venovenous malformation (VVM) in the subcutaneous space of the left inguinal region following an open inguinal hernia repair. This VVM presented as a spontaneous rupture leading to widespread ecchymosis of the thigh. It was managed endoscopically.
