We report the case of a 38-year-old woman who was admitted due to right limb numbness. A right-to-left shunt (RLS) was detected by transthoracic contrast echocardiography (cTTE), and microbubbles appeared in the left heart seven cardiac cycles after opacification of the right heart, suggesting pulmonary arteriovenous fistula. This was supported by computed tomography angiography. She underwent thoracoscopic partial right lower pneumonectomy and recovered after surgery. At 1 year follow-up, she had no relapse of stroke or cerebral infarction. This case shows the typical signs of pulmonary arteriovenous fistula on contrast-enhanced trans-thoracic echocardiography, which allowed an accurate and rapid diagnosis.
我们报告了一例38岁因右肢麻木入院的女性病例。经胸对比超声心动图（cTTE）检测到右向左分流（RLS），右心显影后七个心动周期左心出现微泡，提示存在肺动静脉瘘。计算机断层血管造影证实了这一点。她接受了胸腔镜下右肺下叶部分切除术，术后恢复良好。随访1年，她没有中风或脑梗死复发。该病例显示了经胸对比超声心动图上肺动静脉瘘的典型征象，从而实现了准确快速的诊断。
