Image guided retrieval of foreign body: as a bail – out procedure

Abstract

Introduction: Since there has been a wide spread use of plastic catheter and tubing for placement of continuous dialysis, parenteral nutrition , central line insertions and other port catheter insertions, there has been an increase in incidence of “lost� tubing , broken tubing or a component of the entire assembly within the vascular tree or other tissues. Aims & Objectives: To understand and review the various techniques and outcomes used by the Interventional Radiology department in management of retrieval of intravascular foreign bodies. Materials and methods: Patients referred to the department of Interventional radiology on an Emergency or elective basis were evaluated on Ultrasound, CT or DSA and were treated under fluoroscopy and ultrasound guidance with informed consent on elective cases. Results: Of 13 cases referred to the department of Vascular and Interventional Radiology 3 cases were iatrogenic complications occurred during performing the procedures in the department while 10 cases were referred for other departments. All the procedures went uneventful without any complications. Snare was the most common retrieval device used for IFB removal in most of the cases (11 cases), balloon was used in one case. Femoral (venous) access was most common access used. Conclusion: Vascular and interventional radiology is a recent upcoming branch which due to advances in physics and technology has provide a vast spectrum of possibilities in therapy of patients through minimal access and lesser morbidity. A proper technique, equipment and approach is necessary for each of such cases so as to tackle them without causing any additional injury to the vasculature.
