To describe the internal pudendal artery (IPA) and accessory pudendal artery (APA) detected by magnetic resonance (MR) angiography to help surgeons to find and preserve them during radical prostatectomy (RP).
Constrast-enhanced MR 3.0 T angiography of the pelvis were performed in 111 male patients suspected diagnosis of prostate cancer (PCa), and describe the penile arterial blood supply.
There are three patterns of the arterial blood supply to the penis (IPA and/or APA) accounting for 51.4%, 46.8% and 1.8% of cases, respectively. About the accessory pudendal artery (APA): 54/111 (48.6%) patients had APA with five different branching patterns, they were type I (APA bilateral symmetry): 17 (31.5%); type II (APA bilateral asymmetry): 1 (1.9%); type III (APA unilateral lateral): 13 (24%); type IV (APA unilateral apical): 21 (38.9%); type V (APA unilateral mix): 2 (3.7%). APA origin were from inferior epigastric artery (IEA): 7 (9.5%); from inferior vesical artery (IVA): 32 (43.2%); from obturator artery (OA): 35 (47.3%).
A precise angioanatomic evalutation of arteries destined to the penis by MR angiography pre-operation for male pelvic organs will help surgeons to preserve them and contributes to reduce the erectile dysfunction after these procedures.
描述通过磁共振（MR）血管造影检测到的阴部内动脉（IPA）和副阴部动脉（APA），以帮助外科医生在根治性前列腺切除术（RP）期间找到并保留它们。
对111例疑似前列腺癌（PCa）诊断的男性患者进行盆腔3.0 T对比增强MR血管造影，并描述阴茎动脉血供情况。
阴茎动脉血供（IPA和/或APA）有三种模式，分别占病例的51.4%、46.8%和1.8%。关于副阴部动脉（APA）：54/111（48.6%）例患者有APA，有五种不同分支模式，分别为I型（双侧对称APA）：17例（31.5%）；II型（双侧不对称APA）：1例（1.9%）；III型（单侧外侧APA）：13例（24%）；IV型（单侧顶端APA）：21例（38.9%）；V型（单侧混合APA）：2例（3.7%）。APA起源于腹壁下动脉（IEA）：7例（9.5%）；起源于膀胱下动脉（IVA）：32例（43.2%）；起源于闭孔动脉（OA）：35例（47.3%）。
术前通过MR血管造影对男性盆腔器官的阴茎供血动脉进行精确的血管解剖评估，将有助于外科医生保留这些动脉，并有助于减少这些手术后的勃起功能障碍。
