摘要

虽然大动脉转位(TGA)的动脉转位手术(ASO)的短期和中期疗效有了很大改善,但也有一些并发症的报道,包括肺动脉狭窄、主动脉瓣功能不全和主动脉根部扩张。主动脉瓣置换术(ASO)后,原来的肺动脉根部和瓣膜分别作为新主动脉根部和瓣膜在全身位置发挥作用,但它们暴露在全身血压下,导致一些患者主动脉根部扩张和瓣膜功能不全。这些并发症的风险因素之一是既往肺动脉束扎术(PAB)史。复杂的 TGA 解剖结构,包括大动脉转位和室间隔缺损(TGA-VSD)或双出口右心室和室间隔缺损(DORV-VSD),也是新主动脉扩张和主动脉瓣反流的一个独立危险因素。对于 ASO 后长期患有这些病变的患者,有时需要进行主动脉瓣和主动脉根部置换术。在此,我们介绍了一名自 ASO 后出现持续性主动脉窦扩张和主动脉瓣功能不全的患者,该患者在 ASO 15 年后因 PAB 而需要进行主动脉瓣根部和瓣膜置换术。患者接受了 Bentall 手术,临床疗效良好。主动脉根部置换术后的组织学检查结果显示,新主动脉壁(原为肺动脉)与原始主动脉壁在结构上没有明显差异。

Persistent neo-aortic root dilatation and aortic valve insufficiency after arterial switch operation following prior pulmonary artery banding.

Although there have been great improvements in the short- and medium-term outcomes of the arterial switch operation (ASO) for transposition of the great arteries (TGA), some complications including pulmonary artery stenosis, aortic valve insufficiency, and aortic root dilatation have also been reported. After ASO, the original pulmonary root and valve, which function in the systemic position as the neo-aortic root and valve respectively, are exposed to the systemic blood pressure, resulting in aortic root dilatation and valve insufficiency in some patients. One of the risk factors for these complications is a history of prior pulmonary artery banding (PAB). Complex TGA anatomy, including transposition of the great arteries and ventricular septal defect (TGA-VSD) or double outlet right ventricle and ventricular septal defect (DORV-VSD), is also an independent risk factor for neo-aortic dilatation and aortic valve regurgitation. Aortic valve and root replacement is sometime necessary for the patients with these pathologies long-term after ASO. Here, we present a patient who had persistent aortic sinus dilatation and aortic valve insufficiency since ASO and necessitating aortic root and valve replacement 15 years after ASO preceded by PAB. The patient underwent Bentall operation and his clinical course was favorable. Histological findings after root replacement revealed no remarkable structural difference between neo-aortic wall (originally pulmonary artery) and original aortic wall.

期刊介绍: The primary aim of the Indian Journal of Thoracic and Cardiovascular Surgery is education. The journal aims to dissipate current clinical practices and developments in the area of cardiovascular and thoracic surgery. This includes information on cardiovascular epidemiology, aetiopathogenesis, clinical manifestation etc. The journal accepts manuscripts from cardiovascular anaesthesia, cardiothoracic and vascular nursing and technology development and new/innovative products.The journal is the official publication of the Indian Association of Cardiovascular and Thoracic Surgeons which has a membership of over 1000 at present.DescriptionThe journal is the official organ of the Indian Association of Cardiovascular-Thoracic Surgeons. It was started in 1982 by Dr. Solomon Victor and ws being published twice a year up to 1996. From 2000 the editorial office moved to Delhi. From 2001 the journal was extended to quarterly and subsequently four issues annually have been printed out at time and regularly without fail. The journal receives manuscripts from members and non-members and cardiovascular surgeons. The manuscripts are peer reviewed by at least two or sometimes three or four reviewers who are on the panel. The manuscript process is now completely online. Funding the journal comes partially from the organization and from revenue generated by subscription and advertisement.
