To assess the usefulness of a technique for inserting hookwires guided by computed tomography to locate and resect pulmonary nodules by video-assisted thoracoscopy. To describe the procedure and its complications.
Nine pulmonary nodules were located in nine patients. All were </= 2 cm in diameter, radiologically undefined and of unknown origin. Four patients had a history of cancer. The nodules were located using the needle/hookwire system (Kopans), guided by computed tomography and were resected by video-assisted thoracic surgery.
The hookwire was placed correctly in 8 patients and incorrectly in 1. Thoracotomy was necessary for 1 patient. The histologic diagnosis was benign for all 9 nodules; 5 were hamartomas, 2 were necrotic or fibrotic nodules, 1 was a granuloma and 1 was an anthracotic node. Hospital stay ranged from 1 to 8 days (mean 3.3 days).
The location of pulmonary nodes by hookwire and needle for later resection by video-assisted thoracoscopic surgery is a simple, safe way to facilitate removal in some cases, for diagnosis and treatment.
评估在计算机断层扫描引导下插入钩丝以定位并通过电视辅助胸腔镜切除肺结节的技术的实用性。描述该操作及其并发症。
9名患者体内发现9个肺结节。所有结节直径均≤2 cm，影像学上不明确且来源不明。4名患者有癌症病史。在计算机断层扫描引导下，使用针/钩丝系统（科潘斯）定位结节，并通过电视辅助胸外科手术切除。
8名患者的钩丝放置正确，1名患者放置错误。1名患者需要开胸手术。所有9个结节的组织学诊断均为良性；5个为错构瘤，2个为坏死或纤维化结节，1个为肉芽肿，1个为炭末沉着结节。住院时间为1至8天（平均3.3天）。
通过钩丝和针定位肺结节，随后通过电视辅助胸腔镜手术切除，在某些情况下是一种简单、安全的方法，有助于诊断和治疗。
