摘要
由于各种原因所导致的气道狭窄往往需要进行支架植入术以实现气道的快速扩张,缓解患者的呼吸困难。人体气道支架的灵感来源于心血管支架的临床应用,且自1965年Montgomery发明了T型管状硅酮橡胶支架用于气道狭窄的治疗之后,气道支架便得到不断地推陈出新。目前临床上使用的气道支架主要有Dumon硅酮支架和镍钛记忆合金支架。虽然气道支架的植入可以迅速地改善患者的呼吸状况,但支架植入后仍可能会导致一些较为棘手的并发症,例如支架移位、肉芽组织的过度增生以及支架附近组织的感染等。近年来,有关药物洗脱气道支架、生物可降解气道支架的基础研究,为气道支架未来的发展带来了新的曙光,同时,基于生物3D打印技术制备的个性化气道支架可以使得支架与气道实现完美的贴合,既可以降低支架发生移位的风险,又可以实现对肉芽组织过度增生的抑制,必将成为今后气道支架的重要发展趋势之一。
The implantation of airway stent can dilate the airway stenosis quickly and give patients relief from the breathing difficulty. Airway stent takes inspiration from the clinical use of vascular stent and it has been innovated continuously since 1965, when the T-shape silicone airway stent was invented by Mont- gomery for the treatment of airway stenosis. Currently, Dumon silicone airway stents and nickel titanium shape memory alloy airway stents are widely used in clinics. However, there are still some complications, such as the migration of stent, the excessive growth of granulation tissue and the infections nearby the stent. In recent years, the investigations on the drug-eluting airway stent and the biodegradable airway stent shed new light on the airway stent. Moreover, the patient-specific airway stent based on the 3D print- ing technology will be one of the important trends for the reason of perfect fit, the low risk of migration and the inhibition of the granulation tissue excessive growth.
