Abstract

Aim: To describe anatomical characteristic of prostatic artery on DSA scan of patient with benign prostatic hyperplasia (BPH). Material and method: Prospective and retrospective study on DSA scan of 20 male patients with BPH at Radiology Center of Hanoi Medical University Hospital from August 2018 to August 2021. Result: On 33 pelvis sides scan of 20 patients which reveals prostatic artery, there are 2 pelvis sides have two PAs (accounts for 6.1%), 31 pelvis sides have single PA (accounts for 93.9%). In terms of origin among 35 PAs found, according to Francisco Canervalle classification, the ratio of type I (originating from common vesical trunk), type II (originating from anterior trunk of internal iliac artery), type III (originating from obturator artery), type IV (originating from internal pudendal artery) and type V (other origins) are, respectively: 20%; 2.9%; 34.3%; 31.4% and 11.4%. Atherosclerosis was observed in 11.4% of PAs. The “corkscrew” pattern was found in 30.4%. The average diameter of PAs was 1.53 ± 0.34 mm. Collateral circulations between PAs and other vessels were also observed: 31.4% of Pas anastomose with penile artery, 17.1% of PAs anastomose with branches supplying seminal vesicle, 37.1% anastomose with contralateral PA. Conclusion: The origin of type III is the most common variation in this study. The existence of anastomose of PAs indicates that common anatomy of PAs and its variations are essential factors affect the treatment of BPH.
