Abstract
Objective To analyze the clinical features of the patients with cryptogenic stroke caused by pulmonary arteriovenous fistula (PAVF), and compare the characteristics of different diagnostic methods to ifnd preliminary screening method. <br> Methods Detailed clinical data of 2 patients with cryptogenic stroke were collected. Transesophageal echocardiography (TEE) and contrast transcranial Doppler (cTCD) were performed. <br> Results cTCD in 2 patients showed the following characteristics of microemboli signals: late appearance, large number, long duration, and the number was not inlfuenced by Valsalva maneuver (VM). TEE showed that there were no abnormal CDFI and large number of microbubbles appeared in the left atrium at 5th cardiac cycle after VM. <br> Conclusion Ischemic stroke is the most common extra-pulmonary manifestation of PAVF, inlfuenced by the diameter of feeding artery and quantity of PAVF. cTCD combined with arterial blood gas analysis is useful for preliminary screening, efifcacy evaluation and follow-up for PAVM.关键词
