Cirurgia de Grayhack no tratamento de priapismo isquémico – a propósito de um caso clínico

Abstract

Ischemic priapism is a persistent erection unrelated to sexual stimulation characterized by reduced or absent intracavernous blood flow. We present a clinical case of a 30 year old man with priapism with 48 hours of progression. He underwent surgical drainage of the corpora cavernosa, instillation of ephedrine, and creation of a cavernous‐spongeous shunt without improvement. On the duplex ultrasound there was no flow in the cavernous arteries, thrombosis of the cavernous veins and normal dorsal venous flow. He underwent Grayhack surgery with creation of cavernous‐femoral bypass with great saphenous vein bilaterally. He underwent a Grayhack surgery with creation of a bilateral cavernous‐femoral bypass with great saphenous vein. There was clinical improvement and resolution of the priapism. On the 7th post‐operative day, it was documented thrombosis of the bypasses and patent cavernous arteries and veins.
