TUMOR VASCULAR FLOW CONTROL BY MRI AFTER LOCOREGIONAL TREATMENT OF SMALL P-NETS BY EUS-RFA A CASE SERIES

Video Transcription

Video Summary

This case series evaluates MRI-guided tumor vascular flow control following AUS-RFA treatment of small pancreatic neuroendocrine tumors (PNATs). It highlights challenges in detecting small insulinomas and non-functional PNATs. Four cases were discussed involving patients undergoing AUS-RFA for well-differentiated neuroendocrine tumors. Repeated ablations were often needed to achieve tumor disappearance and absence of vascular flow. MRI provided effective immediate assessment. The series concludes that AUS-RFA is a safe, less invasive alternative for patients unfit for surgery or those opting against it, emphasizing the importance of AUS tissue procurement before treatment. Only one self-limited bleeding episode was noted.
