Functional and anatomic evaluation of penile arterial blood flow is essential in the work up of erectile dysfunction. Duplex ultrasonography is an ideal screening modality with cavernosal mean peak systolic blood flow velocity being the most sensitive predictor of arterial disease. Arterial variability of the penis may affect sonographic evaluation leading to frequent misinterpretation and therefore pudendal arteriography remains the current gold standard for penile arterial evaluation. Appreciation of the type and frequency of anatomic variants and potential collateral routes is important in interpreting penile arteriograms and in evaluating the hemodynamic significance of suspected arterial disease.
阴茎动脉血流的功能和解剖学评估在勃起功能障碍的检查中至关重要。双功超声检查是一种理想的筛查方式，海绵体平均收缩期峰值血流速度是动脉疾病最敏感的预测指标。阴茎的动脉变异性可能会影响超声检查评估，导致频繁的错误解读，因此阴部动脉造影术仍是目前阴茎动脉评估的金标准。了解解剖变异的类型和频率以及潜在的侧支循环途径，对于解读阴茎动脉造影和评估疑似动脉疾病的血流动力学意义非常重要。
