Intracardiac migration of distal catheter—a rare complication of VP shunt insertion: case report and literature review

Abstract

Intracardiac migration is a rare complication of ventriculoperitoneal shunt insertion. Only 15 cases have been reported, 7 of which were paediatric cases, treated with techniques including interventional radiography, open thoracotomies and direct extraction through the initial shunt incision. The authors report the youngest case of intracardiac shunt migration complicated by significant coiling and knotting within the cardiac chambers and pulmonary vasculature. Migration likely began when the SVC was pierced during initial shunt placement and progressed due to negative intrathoracic pressure. Extrusion was achieved combining thoracoscopic endoscopy, interventional fluoroscopy screening and a posterolateral neck incision with uncoiling of the shunt via a Seldinger guide wire. This offered a minimally invasive solution with rapid post-operative recovery.
