Traumatic cavernosal artery pseudoaneurysm: a rare cause of erectile dysfunction following pelvic trauma: a case report and comprehensive literature review

Abstract

Introduction and importance: Erectile dysfunction (ED) resulting from pelvic trauma, particularly cavernosal artery pseudoaneurysm, poses a complex clinical challenge. Traumatic injuries, including blunt force trauma, can lead to diverse vascular complications affecting erectile function. Recognizing and addressing these issues is pivotal for optimal patient management. Case presentation: A 40-year-old male presented with gradual-onset ED following a traumatic incident, involving a fall from a bike and subsequent hematoma on the penile shaft. Despite initial successful conservative management, the patient experienced recurrent symptoms. Comprehensive evaluation, including ultrasonography and computed tomography (CT) angiography, revealed a cavernosal artery pseudoaneurysm. The diagnostic journey involved Doppler ultrasound and penile arteriography, confirming the arteriogenic etiology. Clinical discussion: Pelvic trauma, a common cause of erectile dysfunction in men under 40, can lead to cavernosal arterial injuries and pseudoaneurysms. This condition often results from blunt perineal trauma or iatrogenic factors, requiring precise diagnostic tools like Doppler ultrasound and penile arteriography. Treatment options include coil embolization and Gelfoam application, emphasizing the importance of timely intervention. Conclusion: Successful angiography and coil embolization yielded significant improvement in symptoms for the presented case. This underscores the critical role of accurate diagnosis and tailored interventions in addressing cavernosal artery pseudoaneurysms resulting from pelvic trauma, thereby enhancing patient outcomes and quality of life.
