Description
Objectives To evaluate the prostatic arterial supply with multidetector Angio CT and Digital Subtraction Angiography (DSA). Methods DSA was performed in 21 male patients (7 of these also underwent Pelvic Angio CT); a further 4 patients only underwent Angio CT. Prostatic arteries were classified according to their origin, direction, number of pedicles, termination and anastomoses with surrounding arteries in 50 pelvic sides. Results The most frequent origin was the internal pudendal artery (n = 28; 56%) with the common gluteal-pudendal trunk the next commonest (n = 14; 28%). Less frequent origins were the obturator artery (n = 6; 12%) or the inferior gluteal artery (n = 2; 4%). Two separate vascular pedicles were found in 12 pelvic sides (24%). There were anastomoses with the termination of the internal pudendal artery in 24% of cases (n = 12), with the contra-lateral prostatic arteries in 6 cases (12%), and to the superior vesical artery in 4 cases (8%). Conclusions Defining prostatic artery origin and direction is paramount to allow selective catheterisation. Angio CT is very useful as a pre-intervention tool. The number of independent vascular pedicles and the presence of anastomoses with surrounding arteries should be taken into account when planning prostatic arterial embolisation.
