IMPACT OF PREOPERATIVE TRANSCATHETER ARTERIAL EMBOLIZATION ON BLOOD LOSS AND SURGERY TIME DURING ENDOSCOPIC TRANSNASAL RESECTION OF JUVENILE ANGIOFIBROMA: A RETROSPECTIVE STUDY

Objective: to determine the effect of preoperative transcatheter arterial embolization (pTAE) on intraoperative blood loss and surgery time for endoscopic transnasal resection of juvenile nasopharyngeal angiofibroma (JNA). Methods: A retrospective analysis was conducted on thirty adolescent male patients who received surgical treatment at the University Medical Center (UMC) from February 2014 to December 2023. The cohort was divided into two groups: those who underwent preoperative transcatheter arterial embolization (n=19) and those who did not (n=11). The characteristics that were compared included blood loss and duration of surgery. Results: Patients who received pTAE had a significant reduction in intraoperative blood loss for all stages of JNA. Although pTAE reduced the amount of time needed for surgery, the results were not statistically significant. Conclusions: Preoperative pTAE greatly enhances surgical results by successfully reducing intraoperative bleeding during JNA resection.
