前立腺の動脈造影に関する研究 第1編:前立腺栄養血管の検討

Abstract

Pelvic arteriographies of 51 cases were performed by Seldinger's method with use of autoinjector. Out of 51 cases, 10 cases were patients of non-prostatic disease (elder than 40 years old), 21 cases were ones of benign prostatic hypertrophy and 20 cases were ones of prostatic cancer. 1) On pelvic arteriograms, main nutrient vessels of the prostate were branches of inferior vesical artery, middle rectal artery and internal pudendal artery. 2) Inferior vesical artery originated from internal pudendal artery (27.2%), inferior gluteal artery (25.2%), umbilical ligament (18.4%) or the others. Findings of asymmetrical running of left and right inferior vesical artery or dilatation of one were seen in some cases of benign prostatic hypertrophy or prostatic cancer, though were not seen in ones of non-prostatic disease. 3) Middle rectal artery originated from internal pudendal artery (53%), inferior vesical artery (12%), inferior gluteal artery (9%) or the others. Findings of asymmetrical running ofleft and right middle rectal artery or dilatation of one were seen in some cases of benign prostatic hypertrophy or prostatic cancer, though were not seen in ones or non-prostatic disease. 4) Internal pudendal artery originated from internal iliac artery (51 %), pudendo-gluteal trunk (33%), inferior gluteal artery (11 %) or the others. Branches of internal pudendal artery which distributed to the prostate were seen in some cases of benign prostatic hypertrophy or prostatic cancer, though were not seen in ones of non-prostatic disease. 5) In some cases, pelvic arteriograms showed branches of superior rectal artery, superior vesical artery, lateral sacral artery or middle sacral artery, which distributed to prostate with exception of branches of three main arteries as mentioned above.
