Abstract

Thoracic surgeons using minimally invasive techniques for lung nodule resection often rely on localization markers to determine precise nodule location intraoperatively. Transbronchial or transthoracic injection of indocyanine green (ICG) dye has become a popular technique. However, surgery must be performed immediately before dye dissipates into surrounding tissue. This multicenter retrospective study evaluated the effectiveness of computed tomography (CT)-guided transthoracic placement of ICG dye-soaked coils (ICG-Cs) for preoperative lung nodule localization. Nineteen adult patients with 21 nodules underwent CT ICG-C placement from March 01, 2023, until February 28, 2025, at 2 medical centers. There were no adverse events. Median time from localization to surgery was 1 day (interquartile range, 0-4 days), with 57.1% undergoing surgery >24 hours later. Localization success rate was 100%. CT-guided transthoracic placement of ICG-C is a novel technique that allows for accurate nodule localization, delayed surgical resection, and the preservation of healthy lung tissue.

经皮吲哚菁绿染料浸泡栓塞线圈标记肺肿瘤：肺保留手术术中准确定位的视觉信标。

胸外科医生采用微创技术进行肺结节切除术，术中往往依靠定位标记来确定精确的结节位置。经支气管或经胸注射吲哚菁绿（ICG）染料已成为一种流行的技术。然而，手术必须立即进行，因为染料会消散到周围组织。本多中心回顾性研究评估了CT引导下经胸放置ICG染料浸透线圈（CT ICG- c）在术前肺结节定位中的效果。2023年3月1日至2025年2月28日，19例21个结节的成年患者在两个医疗中心接受了CT ICG-C定位。没有不良事件发生。从定位到手术的中位时间为1天（IQR 0 ~ 4天），57.1%的患者在24小时后接受手术。本地化成功率100%。CT ICG-C是一种新颖的技术，可以精确定位结节，延迟手术切除，并保留健康的肺组织。

期刊介绍： JVIR, published continuously since 1990, is an international, monthly peer-reviewed interventional radiology journal. As the official journal of the Society of Interventional Radiology, JVIR is the peer-reviewed journal of choice for interventional radiologists, radiologists, cardiologists, vascular surgeons, neurosurgeons, and other clinicians who seek current and reliable information on every aspect of vascular and interventional radiology. Each issue of JVIR covers critical and cutting-edge medical minimally invasive, clinical, basic research, radiological, pathological, and socioeconomic issues of importance to the field.
