Migration of an Implantable Port Catheter into the Right Pulmonary Artery: A Rare Complication in a Child Followed for Testicular Rhabdomyosarcoma

Abstract

Introduction: The implantable catheter chamber (ICC) is today a crucial tool in the management of cancer patients receiving chemotherapy. As an invasive device, it carries risks that can be infectious, mechanical, and thromboembolic. Case Presentation: We report a case of a young child with this rare but potentially serious migration. To receive his chemotherapy treatment, our patient benefited from the placement of an ICC at the subclavian vein via a percutaneous technique. The patient was asymptomatic, and the migration was discovered on the chest X-ray performed for the ablation. The transthoracic echocardiography performed on March 29, 2023, found the catheter in the right pulmonary artery. The removal of the migrated catheter was successfully performed by percutaneous endovascular catheterization techniques under mild sedation. Conclusion: The rupture and migration of the catheter of the implantable chamber at the level of the pulmonary artery, remains rare, the endovascular catheterization is an option of ablation.
