We report pathological findings of the aortic homograft in a 27-year-old patient who died 20 years after implantation at the time of correction of tetralogy of Fallot. Although calcification of the homograft was severe with degeneration of valve leaflets, no functional obstruction of the homograft was found as a conduit. This observation may suggest a beneficial aspect of the aortic homograft as the right ventricle to the pulmonary artery conduit late after corrective surgery even if calcification was not avoided.
我们报告了一名27岁患者主动脉同种异体移植物的病理结果，该患者在法洛四联症矫正术后20年植入移植物，死亡时进行尸检。尽管同种异体移植物钙化严重且瓣叶退变，但未发现该移植物作为管道存在功能性梗阻。这一观察结果可能提示，即使无法避免钙化，在矫正手术后晚期，主动脉同种异体移植物作为右心室至肺动脉的管道仍有有益的一面。
