Penile Revascularization for Erectile Dysfunction Secondary to Arterial Insufficiency: A Case Series.

[BACKGROUND] First described by Michal et al in 1972, penile revascularization for vasculogenic impotence and its outcomes has been scarcely reported in plastic surgery literature. Such injuries are often secondary to atherosclerosis of the distal internal pudendal, common penile or proximal cavernosal artery, or locoregional trauma. Various techniques have been described to restore blood flow to the cavernosal body.

[METHODS] In this report, we review 2 cases of penile revascularization for arteriogenic erectile dysfunction at our level 1 trauma center in 2021-2022 completed by the senior author in conjunction with urology.

[RESULTS] Both patients sustained pelvic crush injuries with resultant arteriogenic impotence minimally responsive to medical management with phosphodiesterase inhibitors and/or injection therapy. After thorough urologic and vascular workup, they underwent microsurgical revascularization of the penis utilizing the deep inferior epigastric arteries with anastomosis to the deep dorsal penile veins. Both patients demonstrated improvement in erectile dysfunction and were able to achieve sustained erection with adequate glans tumescence on minimal pharmacotherapy postoperatively. One patient noted ability to achieve penetration. Patient 1 experienced postoperative retention requiring Foley placement, and both patients experienced glans edema requiring additional urologic procedures (patient 1: dorsal slit, patient 2: completion circumcision).

[CONCLUSIONS] Overall, we have demonstrated improvement of sexual function with the most common complication being prolonged penile edema requiring release of constriction by our urology colleagues. Additional research in the plastic surgery field is warranted to further refine the technique and improve outcomes.
