Novel use of a mechanical suction thrombectomy system for interposition graft occlusion in complex congenital heart disease.

Complete thrombosis of a pulmonary artery interposition graft in an adolescent with complex repaired CHD was treated successfully with a combination of a novel mechanical thrombectomy system, stent implantation, and thrombolysis. This thrombectomy system used a flexible catheter with a built-in mechanism to attenuate blood loss, while providing effective recanalisation of a foreign graft.
