The Efficacy and Safety of Transcatheter Arterial Embolization to Treat Renal Hemorrhage after Percutaneous Nephrolithotomy

Figure 3

(a) Selective renal arteriogram shows a PA arise from the left posterior anterior segmental artery in a 54-year-old man. (b) Renal arteriography during the arterial phase shows a PA (thin arrow) and contrast agent extravasation along the drainage pipe (thick arrowhead) arising from the posterior and superior anterior interlobar artery. (c) After embolization with 3 coils (TORNADO MWCE-18S-3.0-2, Cook Inc.), there is no contrast medium extravasation again under angiogram. (d) After embolization, digital subtraction angiographic imaging shows complete occlusion of the PA and contrast agent retention.
