Intentionally unilateral prostatic artery embolization: Patient selection, technique and potential benefits

Figure 1 Representative images from a clinically successful case of intentionally unilateral prostatic artery embolization (subgroup A). A: Right prostatic artery (PA) angiogram (frontal projection) with the microcatheter tip at the extraprostatic part of the PA (arrow) shows opacification of the largest part of both prostatic lobes; B: Right PA angiogram (oblique projection) post embolization shows extensive devascularization of the prostate and a small area of residual enhancement at the left lobe (dotted arrow); C: Dual image from intraprocedural contrast-enhanced ultrasonography (contrast-enhanced image on the left, unenhanced reference B-mode image on the right) 2 minutes post embolization, confirms the absence of enhancement in the largest part of the prostate (inf), with residual enhancement only at the periphery of the left lobe (dotted arrow). Echogenic areas (arrows) in the unenhanced image of the prostate are caused by accumulation of the embolic mixture. The balloon of the Foley catheter is indicated by “f”.
