Treatment of Pediatric Traumatic Intracranial Pseudoaneurysm Using Endovascular Covered Stent: Three Case Reports.

Background Pediatric traumatic intracranial pseudoaneurysm (TIPA) is a relatively rare clinical entity resulting from blunt, penetrating, or iatrogenic head trauma. The diagnosis, management, and prognosis of patients with pediatric TIPA is not well understood. Surgical craniotomy for TIPA is a high-risk operation. Advancements in minimally invasive technology have allowed for endovascular reconstruction of TIPA. Case Description We present our experience with use of endovascular covered stents for treatment of 3 pediatric patients with TIPA. The clinical and radiologic characteristics are presented. No procedure-related complications or deaths occurred during follow-up. Conclusions In this study, the use of the Willis covered stent was associated with favorable prognoses in 3 patients with TIPA. No major complications were encountered during follow-up. The Willis covered stent appears to be a viable therapeutic modality in these patients. A definitive prognosis assessment will necessitate prospective clinical trials with longer duration of follow-up.
