Selective internal radiation therapy (SIRT) is a catheter-guided treatment offered to selected patients with primary and secondary liver malignancies. SIRT is preceded by a workup procedure, where 99mTc-MAA (macroaggregated albumin) is injected in the tumor supplying artery/arteries followed by MAA scintigraphy. SIRT is frequently offered to patients with hepatocellular carcinoma (HCC), but large HCCs are known to be associated with a high risk of liver-to-lung shunting. We present a HCC patient case where a large lung-shunt enabled diagnosis of pulmonary embolism.
选择性内放射治疗（SIRT）是一种导管引导的治疗方法，适用于原发性和继发性肝恶性肿瘤的选定患者。SIRT 之前需要进行一项工作程序，在该程序中，将 99mTc-MAA（巨聚合白蛋白）注入肿瘤供血动脉/动脉中，然后进行 MAA 闪烁照相术。SIRT 经常提供给患有肝细胞癌（HCC）的患者，但众所周知，大 HCC 与肝肺分流的高风险相关。我们提出了一个 HCC 患者的病例，其中大量的肺分流使肺栓塞的诊断成为可能。
