Pre-vascular hernia: a rare cause of chronic obscure groin pain after inguinal hernia repair.

A rare case of pre-vascular hernia is reported in a woman complaining of chronic obscure groin pain following an inguinal hernia repair. The condition was only diagnosed by means of a herniogram, emphasising the value of this investigation in unexplained groin pain. The hernia was successfully repaired using a polypropylene mesh plug, a simple technique widely employed in both femoral and recurrent inguinal hernia, but never before described in pre-vascular hernia.
