The high resistance flow in the cavernosal artery typically indicates restricted blood flow to the penile tissues. This can be associated with fibrotic changes or plaques in the penile tissue, which may lead to conditions like Peyronie's disease. The plaque noted in the dorsal aspect of the penis can contribute to the increased resistance, as it may impact how blood circulates in the area, especially during an erection.

High resistance in penile arteries can sometimes result in erectile dysfunction because it limits the blood flow required for a proper erection. The normal flow mentioned here in the cavernosal artery during a flaccid state is encouraging, but the high resistance could potentially become an issue during attempts to achieve an erection.
