摘要

气管支气管软化症(TBM)是气管和/或主要支气管软骨支撑的丧失,导致呼吸过程中气道的动态塌陷。它通常在两岁时消退。严重病例通常表现为复发性肺炎,需要住院治疗,在疾病或手术后无法拔管,或发生危及生命的事件。方法我们报道了澳大利亚首例使用3D打印技术成功植入气管夹板治疗21个月大、无创治疗失败的严重TBM患者的病例。他的病情无法通过其他已建立的气道手术得到改善。在悉尼儿童医院网络气管重建组进行多学科讨论后,CS Mott儿童医院的多学科团队进一步讨论了该病例,以协助手术计划和定制支架设计。澳大利亚治疗用品管理局(Australian Therapeutic Goods Administration)正在寻求对这些设备的批准。获得了医院主管人员以及新南威尔士州社区和司法部门的同意。结果胸骨切开手术采用体外膜氧合,手术顺利进行。术中行柔性支气管镜检查确定TBM部位。两个气道夹板用于长段气管软化,累及气管远端和左主支气管近端。它们被放置在气管和支气管的前部和外侧表面。术中柔性支气管镜检查证实通畅。5天后拔管。他临床表现良好。结论3d打印气管夹板是治疗重度TBM患儿的又一可行选择。计算机辅助设计和生物材料3d打印为TBM患者创造了解剖特异性植入装置。

Management of severe tracheobronchomalacia with 3D printed resorbable airway splints: An Australian first

Introduction

Tracheobronchomalacia (TBM) is the loss of the cartilaginous support of the trachea and/or major bronchi, leading to the dynamic collapse of the airway during respiration. It usually resolves by the age of two. Severe cases often present with recurrent pneumonias requiring hospitalisations, inability to extubate following illness or procedures, or life-threatening events.

Methods

We present the first Australian case of a successful implantation of tracheal splints using 3D printing technology to treat a 21-month-old with severe TBM who failed non-invasive treatments. His disease could not be improved with other established airway procedures. After multidisciplinary discussions at the Sydney Children's Hospital Network's tracheal reconstruction group, the case was further discussed with the multidisciplinary team at CS Mott's Children's Hospital to assist with surgical planning and the custom design of stents. The Australian Therapeutic Goods Administration's approval for the devices was sought. Consent was obtained from the hospital executives, as well as the New South Wales Department of Communities and Justice.

Results

The surgery was facilitated by placing the patient on extracorporeal membrane oxygenation for the sternotomy. Intraoperative flexible bronchoscopy was performed to confirm the site of TBM. Two airway splints were utilised for the long segment tracheomalacia involving the distal trachea and proximal left main bronchus. They were placed on the anterior and lateral surface of the trachea and bronchus. The patency was confirmed with intraoperative flexible bronchoscopy. The patient was extubated after 5 days. He remains clinically well.

Conclusions

3D printed tracheal splint is another viable alternative for children with severe TBM. The computer aided design and biomaterial 3d printing creates anatomically specific implantable devices for patients with TBM.

期刊介绍: The purpose of the International Journal of Pediatric Otorhinolaryngology is to concentrate and disseminate information concerning prevention, cure and care of otorhinolaryngological disorders in infants and children due to developmental, degenerative, infectious, neoplastic, traumatic, social, psychiatric and economic causes. The Journal provides a medium for clinical and basic contributions in all of the areas of pediatric otorhinolaryngology. This includes medical and surgical otology, bronchoesophagology, laryngology, rhinology, diseases of the head and neck, and disorders of communication, including voice, speech and language disorders.
