Abstract

This case report evaluated the utilization of MR-guided ablation for a refractory painful slow-flow vascular malformation in the plantar aspect of the left foot in a 6-year-old male patient. Initially, MR-guided laser ablation was performed followed by MR-guided cryoablation 5 years later. Procedures were performed under general anesthesia using a 1.5-T Philips MRI system with real-time MRI guidance and monitoring. Pain outcomes were assessed using patient-reported improvement. The lesion diameter was 3.7 cm in the longest axis. The patient achieved sustained pain relief for 5 years after the initial laser ablation then MR-guided cryoablation which has given him 6 years of relief so far. No major complications occurred.

期刊介绍： Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
