Abstract

A lobar ventilation-perfusion mismatch is reported in a patient with right superior pulmonary vein stenosis, developing after radiofrequency ablation for atrial fibrillation. Radionuclide lung perfusion tomography was performed to assist with clinical management. Serial planar lung scintigraphy demonstrated no improvement in the perfusion abnormality despite interventional stenting. Iatrogenic pulmonary vein stenosis may potentially mimic pulmonary embolic disease.

摘要

一位右肺上静脉狭窄的房颤患者在射频消融术后出现局灶性通气-灌注不匹配。为协助临床诊治,进行了放射性核素肺灌注断层显像。尽管进行了介入支架治疗,但系列平面肺闪烁显像显示灌注异常无改善。医源性肺静脉狭窄可能会误诊为肺栓塞。
