“…This discovery is consistent with findings of Nguyen et al [ 30 ], Bilhim et al[ 31 ] Wang et al [ 13 ], de Assis et al[ 9 ] and Amouyal et al[ 19 ] This study is CTA based compared to DSA (+/- CBCT) in most other studies. This study was made to match daily practices (CBCT not available in Ghana) and to stand as a pre procedural planning [ 32 ], knowing especially that the benefit of CBCT is precisely to detect potential accessory PA. For instance, Nguyen et al [ 30 ] found single prostate artery in 630 pelvic halves out of 660 in a Vietnam population (. Bilhim et al[ 16 ] reported single PA in 57% of 150 male pelvic halves among adult in Portugal .…”

“…Regarding types II and III, they are less common than types I and IV, both in the present and in the largest part of previous work, although their prevalence varies significantly among the reports (6-31.1% and 4.7-23.8%, respectively). Interestingly, the herein-reported prevalence of type V (9%) is significantly higher compared to all but one [ 6 ] of the previous studies. The same applies to the main representative of type V in this work, namely, PA origin from the accessory IPA.…”

“…In the first part of this study, the type of PA origin was systematically investigated with CTA and DSA for the first time in a Greek population with BPH. Several studies from other countries have utilized the same system for the categorization of PA origin, and, not surprisingly, there is variance between the results of the present and previous studies [ 3 - 6 , 8 - 11 ], likely due to racial and ethnic differences in pelvic arterial anatomy. In the studied population, the prevalence of the two most common types (I and IV, 31% each) was lower and higher, respectively, compared to the majority of previous articles.…”

“…Type V includes rare PA origins. Subsequent studies [ 4 - 6 ] from different countries utilizing this classification system revealed remarkable variations in the prevalence of the aforementioned types of PA origin. There is probably a place for further research in this field, including populations from countries other than the already studied to enhance knowledge on the variations of prostatic arterial anatomy worldwide.…”

Background This study aimed, first, to angiographically investigate and analyze prostatic artery (PA) origin in a Greek male population with benign prostatic hyperplasia (BPH) treated with prostatic artery embolization (PAE) and, second, to correlate prostatic arterial anatomy with technical and clinical aspects of PAE. Methodology This was a retrospective study of BPH patients who underwent PAE in a single tertiary center in Greece from June 2019 to July 2022. For the first part of the study, PA was imaged with computed tomography angiography (CTA) before PAE and with digital subtraction angiography (DSA) during PAE in all patients. A widely accepted system for the classification of PA origin was applied. Type I, a common origin of PA and superior vesical artery (SVA) from the anterior division of internal iliac artery (IIA). Type II, PA originating from the anterior division of IIA, separate from, and inferior to SVA. Type III, the origin of PA from the obturator artery. Type IV, the origin of PA from the internal pudendal artery. Type V, rarer origins of PA. For the second part of the study, a subgroup of patients from the first part (treated with the same PAE protocol and free of vascular pathology that could have interfered with the technical success of PAE) was selected. In this subgroup, differences in PA origin were correlated with technical aspects (feasibility of catheterization of PA, fluoroscopy time (FT), dose area product (DAP)) and clinical outcomes of PAE. Results After the exclusion of four patients, 159 patients were included in the first part of the study. From a total of 355 PAs, 110 (31%) were compatible with type I, 58 (16.3%) type II, 45 (12.7%) type III, 110 (31%) type IV, and 32 (9%) type V. PA origin from an accessory internal pudendal artery was the most common among the rare origins of type V. Regarding the second part of the study (a subgroup of 101 patients selected to facilitate comparisons between the different types of PA origin), type I was associated with significantly more incidences of failed or difficult catheterization of the PA compared to all other types combined (27/64 vs. 18/138, p < 0.001). Types III, IV, and V showed a relatively low degree of technical difficulty. Patients with type I PA origin of at least one pelvic side (subgroup (I), n = 48) had significantly longer FT and DAP compared to the rest (subgroup (O), n = 53). Clinical success rates of PAE were slightly lower for the subgroup (I), although the difference was not statistically significant (75.8% vs. 83.8% at 18 months post-PAE, p = 0.137). No major complications were observed. Conclusions This is the first study of PA origin in Greece. It was demonstrated that types I and IV of PA origin were the most common and had the same prevalence. Type I showed significantly higher technical difficulty compared to the others, but had no significant impact on the clinical outcomes of PAE.

“…There are cases when we can identify IPA and IPA accessories, which must not be confused with the PA. At the level of accessory IPAs, we can find the origin of the middle rectal artery, which has a characteristic pattern of enhancement that cannot be mistaken with the prostatic blush [12] (Figure 2);…”

Background and Objectives: The purpose of the current paper is to present our study on the variability in the prostatic artery origin, discuss the less frequent origins, and present the challenges of the prostatic artery embolization (PAE) procedure, thus aiding young interventional radiologists. Materials and Methods: We studied the origins of the prostatic artery on digital subtraction angiography (DSA) examinations from PAE procedures on 35 male pelvises (70 hemi-pelvises). Results: Our study has demonstrated that the most frequent origin of the prostatic artery (PA) is the internal pudendal artery (IPA), 37.1%, followed by the anterior gluteal trunk, 27.1%, and the superior vesical artery (SVA), 21.4%. Less frequent origins are the obturator artery (OBT), 11.4%, and the inferior gluteal artery (IGA), 2.8%. Conclusions: Compared to other studies, we notice some differences in the statistical results, but the most frequent origins remain the same. What is more important for young interventional radiologists is to be aware of all the possible origins of the PA in order to be able to offer a proper treatment to their patients. The important aspect that will ensure the success of the procedure without post-procedural complications is represented by the successful embolization of the targeted prostatic parenchyma.
