Abstract

Abstract:

Cryptogenic stroke (CS) is a type of ischemic stroke with an unknown cause, and it is closely associated with right-to-left shunt (RLS). Patent foramen ovale (PFO) and pulmonary arteriovenous fistula (PAVF) are two common types of RLS. While there has been extensive research on PFO, there has been relatively less attention paid to PAVF. Writer provides a review of the clinical features, advances in ultrasonography and imaging diagnostic techniques, as well as treatment methods and prognosis analysis of PAVF, with the aim of providing reference for clinical practice.

Key words: Arteriovenous fistula, Lung diseases, Ultrasonography, Angiography, Review

摘要：

隐源性卒中是一种病因不明的缺血性卒中类型，右向左分流与其发生发展密切相关。卵圆孔未闭和肺动静脉瘘是两种常见的右向左分流类型，目前对卵圆孔未闭的研究较多，但对肺动静脉瘘的研究和关注相对较少。本文对肺动静脉瘘的临床特征、超声及影像学诊断进展，以及治疗方法及预后进行综述，旨在为临床实践提供参考。
