[Prostatic gland arteriography. Vascular supply, diagnosis and differential diagnosis of adenoma and carcinoma of the prostate (author's transl)].

Vascular supply and architecture of the prostate are studied by 100 arteriographic surveys of the pelvis. The prostatic arterial supply can be differentiated in urethral and capsular branches. In a further group of 38 patients with prostate gland disease selective bilateral arteriographies of the internal iliac arteries were performed. In 18 patients with the clinical diagnosis of prostatic adenoma, arteriography detected a carcinoma of the prostate gland. These diagnoses were proven by microscopy. In 10 patients with clinically suspected carcinoma, 5 were diagnosed by arteriography as malignant and also confirmed microscopically. The predominant angiographic criteria of prostatic carcinoma are irregular spotted stain of the involved parenchyma, hypervascularity of the urethral vascular branches, and pathological vessels.
