a) Axial arterial phase contrast enhanced CT in a 23 year old man following a stab wound to the left buttock demonstrates haematoma within the gluteus muscles. Contrast enhancement medially (arrow) represents active haemorrhage from the superior gluteal artery (Somatom sensation, 24 slice,Siemens, Erlangen, Germany). b) A Cobra catheter was negotiated into the posterior (somatic) left internal iliac artery from an ipsilateral approach. Active haemorrhage from a branch of the superior gluteal artery was demonstrated. c) A microcatheter system (Progreat) was negotiated into the bleeding vessel and 2 microcoils (Boston Scientific vortex fibred) were deployed (arrows). This completely abolished the bleeding with good perfusion of the buttock post procedure.
