Abstract:
Objective To study the anatomy and homodynamics of the normal testis vessels in puberty using color Doppler flow imaging to obtain the normal value ranges of each flow parameter and evaluate the waveform characteristics of the testicular and its clinical significances. Methods The anatomy and homodynamic parameters of testicular artery (TA), capsular artery (CA), intratesticular artery (ITA), deferential and cremasteric arteries were studied in 141 normal pubertal volunteers. The following blood flow parameters were included: time average maximum velocity (TAMX), peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI) and resistance index (RI). Results ① The blood flow in TA, CA and ITA was visualized bilaterally in all the subjects; deferential and cremasteric arteries were identified in 98.6% of the subjects. ② The normal ranges of the homodynamic parameters of supratesticular artery, CA and ITA were obtained in puberty. ③ PSV, PI and RI decreased gradually in the following arteries: TA→CA→ITA. Conclusion The testicular arterial anatomy and arterial waveform characteristics of normal pubertal testis can be accurately evaluated by CDFI. It is helpful for the diagnosis and differential diagnosis of testicular diseases in pubertal youngsters.
