Trending cases

Case 1

The hepatic hyperdensities on the previous CT images are arterial aneurysms. Two contrast enhanced images taken at onset of abdominal pain reveal intraparenchymal bleeding consistent w/ rupture. The 1st intervention image shows active extravasation (blue arrows) from R. hepatic branch & multiple L. hepatic branches. The R. hepatic artery branch was embolized first (2nd image). Images 3 & 4 show L. hepatic artery ultra-selective branch coil embolization w/ coil lengths ranging 4-20 mm.

Case 2

18M s/p GSW; CTA demonstrates active extravasation from the mid PT in the calf. Angio demonstrates active extrav/pseudoaneurysm at the proximal to mid PT. Embolized with tornado coils x4 with good result.

Case 3

27 year old Hispanic male presented with 1 month of subjective fevers and night sweats. Clinical labs showed S.viridans in blood and transaminitis. He was subsequently diagnosed with mycotic hepatic artery pseudoaneurysm on Doppler US and CTA. hepatic arteriogram showed a 3cm aneurysm arising from the right hepatic artery.

Case 4

This is multifocal embolic disease without identifiable etiology. Abrupt occlusion of mid-distal R. radial artery and more findings representing upper extremity embolic disease secondary to quadrilateral space syndrome.
