Fig. 1: Selected angiographic and ultrasound images from a case of non-ischemic priapism.
From: Therapeutic outcomes and analysis of Doppler findings in 25 patients with non-ischemic priapism
a Angiogram from the distal internal pudendal artery showing AVF (black arrow) arising from a the right cavernosal artery. b Post embolization angiogram showing resolution of the AVF and normal filling of the penile artery and branches. c Initial diagnostic CDUS trace showing a classical high flow low resistance waveform of NiP (PSV 105 cm/s, EDV 38 cm/s, RI 0.64). d Follow up CDUS at 1 week. The patient had a flaccid penis. The waveform is abnormal with the persistent forward flow in diastole (but much improved compared to the initial diagnostic scan (PSV 69 cm/s, EDV 9.5 cm/s, RI 0.86). e Subsequent CDUS at 3 months a low flow, high resistance waveform (PSV 39 cm/s, EDV -10 cm/s, RI 1.29). AVF arteriovenous fistula, NiP non-ischemic priapism, CDUS colour doppler ultrasound, PSV peak systolic velocity, EDV end diastolic velocity, RI resistive index.
