Pecto-Intercostal Fascial Plane Radiofrequency Ablation for Chronic Post-Sternotomy Pain: A Case Report

Chronic post-sternotomy pain is a clinical problem that can impair quality of life. We report a case of refractory chest pain after coronary artery bypass grafting that was successfully treated using pecto-intercostal fascial plane radiofrequency ablation (PIFP-RFA). A 72-year-old man presented with persistent anterior chest pain that was unresponsive to medication for 1 year. Diagnostic PIFP blocks produced temporary complete pain relief, prompting the decision to perform RFA. Ultrasound-guided PIFP-RFA at the third and fourth parasternal intercostal levels bilaterally achieved complete pain resolution. This case highlights the safety and potential long-term efficacy of PIFP-RFA in patients receiving antithrombotic therapy.
