A nodular lesion at the lower left pulmonary lobe was detected in a 46 years old male during a preoperative chest X-Ray for appendicitis. To further characterise the nodule, a contrast enhanced computed tomography (CE-CT) was performed showing a 20 mm vascular lesion, which was suspected to be a pseudoaneurysm. The diagnostic angiography detected a flattening of the vascular wall with a voluminous pseudoaneurysm (PSA) in the distal portion of the tributary branch of the inferior left lobe. To treat the lesion, a 2.9F microcatheter was advanced into the sac and 4 detachable coils were placed (16-18mm Penumbra Inc) to pack the PSA. To block vascular supply to the lesion, the feeding artery was embolized with an ethylene vinyl alcohol copolymer agent (Squid Peri 18, Emboflu). The final angiographic control showed the exclusion of the pseudoaneurysmal sac which was confirmed by SEMAR™ reconstructed CE-CT scan after 40 days. Furthermore, no signs of pulmonary infarction were reported. (www.actabiomedica.it).
术前胸部 X 光检查发现一名 46 岁男性左下肺叶有一个结节状病变。为了进一步描述该结节，进行了增强对比度计算机断层扫描（CE-CT），显示一个 20 毫米的血管病变，疑似假性动脉瘤。诊断性血管造影发现血管壁变平，在下叶支的远侧部分有一个大的假性动脉瘤（PSA）。为了治疗病变，将 2.9F 微导管推进到囊内，并放置了 4 个可分离的线圈（16-18mm Penumbra Inc）以填充 PSA。为了阻断病变的血管供应，用乙烯-乙烯醇共聚物剂（Squid Peri 18，Emboflu）栓塞供血动脉。最终的血管造影控制显示假性动脉瘤囊被排除，40 天后通过 SEMAR™ 重建的 CE-CT 扫描得到证实。此外，没有报告肺梗死的迹象。（www.actabiomedica.it）。
