卵圆孔未闭封堵器研究进展

Research progress of patent foramen ovale occluder

目前,国内外多项临床研究证实,卵圆孔未闭(PFO)与隐源性卒中密切相关。迄今为止已开发出多种类型卵圆孔封堵器,同时国际上开展了多个大规模临床研究评估经皮卵圆孔介入封堵在预防卒中方面是否有效。本文将围绕不同类型PFO封堵器械设计特点及临床应用作一综述。

At present,many clinical studies at home and abroad have confirmed that patent foramen ovale is closely related to cryptogenic stroke.So far,many types of foramen ovale occluders have been developed,and many large-scale international clinical studies have been carried out to evaluate the effectiveness of percutaneous foramen ovale interventional occlusion in the prevention of stroke.This article will summarize the design characteristics and clinical application of different types of patent foramen ovale devices.
