Images from a patient with lower urinary tract symptoms due to large benign prostatic hyperplasia (107 mL) underwent bilateral PAE. a. Angiography after selective catheterization of the riht prostatic artery (straight arrow) demonstrates contrast staining in the right prostate lobe (asterisk). b. Cone-beam CT image with coronal view after super-selective catheterization of the right prostatic artery demonstrates the the anterior-lateral prostatic branch (arrowhead), supplying to the central gland; the posterior-lateral prostatic branch (straight arrow), supplying to the peripheral and caudal gland. The asterisk indicates the contrast staining in the right prostate lobe and the curved arrow indicates the right internal pudendal artery. c. Angiography after super-selective catheterization of the left prostatic artery (straight arrow) demonstrates the corkscrew pattern of intra-prostate arteriola and contrast medium staining in the left prostate lobe (asterisk). d. Cone-beam CT image with coronal view after super-selective catheterization of the left prostatic artery (straight arrow) demonstrates contrast medium staining in the left prostate lobe (asterisk). The curved arrow indicates a branch of superior vesical artery, usually presented with high pressure injection of contrast medium through the anastomoses.
