Prosthesis choice for aortic valve replacement (AVR) in children is frequently compromised by unavailability of prostheses in very small sizes, the lack of prosthetic valve growth, and risks associated with long-term anticoagulation. The Ross procedure with pulmonary valve autograft offers several advantages for pediatric and adult patients. We describe our current Ross AVR technique including replacement of the ascending aorta with a prosthetic graft. The procedure shown in the video involves an adult-sized male with a bicuspid aortic valve, mixed aortic stenosis and insufficiency, and a dilated ascending aorta.
儿童主动脉瓣置换术(AVR)的假体选择常常受到以下因素的影响:非常小尺寸的假体难以获得、人工瓣膜无法生长以及长期抗凝相关的风险。采用自体肺动脉瓣的Ross手术为儿科和成年患者提供了诸多优势。我们描述了我们目前的Ross AVR技术,包括用人工血管置换升主动脉。视频中展示的手术涉及一名成年男性,患有二叶式主动脉瓣、主动脉瓣狭窄和关闭不全并存以及升主动脉扩张。
