Postoperative catheter thrombaspiration to open an occluded right ventricle-to-pulmonary artery conduit in child

Abstract

Abstract We report on a 6-year-old girl (18 kg/120 cm) who was diagnosed on day 6 postoperative with an occlusive thrombosis of a right ventricle-to-pulmonary artery conduit in the setting of a Ross procedure that was performed for severe native aortic valve insufficiency secondary to late diagnosis of bacterial endocarditis. We applied the Indigo® aspiration system from Penumbra® (Alameda, USA) to mechanically dissolve and remove the thrombus, restore flow, gradually wean from extracorporeal support, and replace the conduit after 4 days. The patient experiences good surgical outcomes at 3 months of follow-up.
