A case of pulmonary arteriovenous malformation (PAVM) in a 32-year-old woman who underwent successful left upper lobectomy is presented. A whole-body technetium-99m-labeled macro-aggregated albumin scan was used to demonstrate intrapulmonary right-to-left shunt, and shunt fraction was calculated as 39%. The patient underwent a follow-up scan after the operation; shunt fraction was calculated to be within normal limits (5%). The whole-body technetium-99m-labeled macro-aggregated albumin scan seems to be a simple and noninvasive test in the demonstration and quantitation of the degree of the right-to-left shunt in pulmonary arteriovenous malformation. The whole-body technetium-99m-labeled macro-aggregated albumin scan may also be useful for evaluation of the hemodynamic changes after surgical treatment and follow-up of the patients with pulmonary arteriovenous malformation.
本文介绍了一例32岁女性肺动静脉畸形（PAVM）患者，该患者接受左上叶切除术并获成功。采用全身锝-99m标记的大聚合白蛋白扫描来显示肺内右向左分流，计算得出分流分数为39%。患者术后接受了随访扫描；计算得出分流分数在正常范围内（5%）。全身锝-99m标记的大聚合白蛋白扫描似乎是一种简单且无创的检查方法，可用于显示和定量肺动静脉畸形中的右向左分流程度。全身锝-99m标记的大聚合白蛋白扫描对于评估手术治疗后血流动力学变化以及肺动静脉畸形患者的随访也可能有用。
