【摘要】：正随着对偏头痛(migraine)、隐源性卒中等发生机制探索的不断深入,右向左分流(right-to-left shunt,RLS)作为可能的发病因素逐渐进入研究者的视野当中。RLS是指左右心房、心室或体循环与肺循环之间存在潜在异常通道,当右心系统压力升高时,与左心系统之间压力梯度增大,血液通过异常通道出现右向左的分流,根据静息时是否出现可分为固有型和潜在型。按照其发生部位可分为心内型分流和心外型分流,前者包括卵圆孔未闭(patent foramen ovale,PFO)、房间隔缺损、室间隔缺损等,后者包括肺动静脉瘘(arteriovenous fis-
[Abstract]:Right to left shunt (right-to-left shunt,RLS), which refers to the left and right atrium, is gradually entering the researchers' field of vision as the possible pathogenesis of migraine (migraine), with the deepening of the exploration of the underlying mechanism of the underlying stroke, the right to left shunt (right-to-left shunt,RLS), which refers to the left and right atrium. There are potentially abnormal channels between ventricular or systemic circulation and pulmonary circulation. When the pressure of the right heart system increases, the pressure gradient increases with the left ventricular system, and the blood shunts from right to left through abnormal channels. It can be divided into intrinsic type and latent type according to whether they appear at rest. It can be divided into intracardiac shunt (patent foramen ovale,PFO), atrial septal defect (ASD), ventricular septal defect (VSD) and extracardiac shunt (patent foramen ovale,PFO). The latter includes pulmonary arteriovenous fistula (arteriovenous fis-).
