Intracardiac migration of a left renal vein stent after endovascular treatment of nutcracker-associated pelvic congestion syndrome: a case report

Abstract Background Left renal vein (LRV) stenting is used in selected patients with symptomatic Nutcracker syndrome (NCS). Stent migration is uncommon but may be serious, particularly in interventions performed primarily for symptom relief. We report intracardiac migration after combined treatment of NCS-associated pelvic congestion syndrome (PCS) and use the event to discuss patient selection, treatment sequencing, and consent in pain-driven venous interventions. Case presentation We report a
