Fig. 9.1
A 45 years old with recurrent epistaxis after gunshot wound. The bullet fragment and shrapnel can be appreciated. Attempts at removal of bullet were also unsuccessful because of the epistaxis. An unsubtracted angiogram performed through guide catheter demonstrates the disruption of the internal maxillary artery (a, arrow). Microangiography in anteroposterior and lateral views demonstrates a traumatic pseudoaneurysm (b, c). Onyx deposition into the pseudoaneurysm (arrow) can be appreciated because of admixture of tantalum powder in it. The microcatheter is also appreciated on the blank roadmaps (d, e). Post-intervention angiography (subtracted) demonstrates obliteration of the pseudoaneurysm (arrow , f, g). This resulted in complete resolution of epistaxis. Subsequently, the large bullet fragment was successfully extracted
