Abstract

The new Vacu-Cut biopsy needle differs from previous types by its simpler manipulation and the production of a stronger vacuum to extract the tissue core. This vacuum is caused by withdrawal of a stylet through an air-tight sealing membrane. The instrument is a hollow needle with an inner cutting-edge and a diameter of 0.95 mm. 49 patients with suspected lesions of the pulmonary parenchyma were biopsied transcutaneously under x-ray monitoring. The biopsy material allowed a clearcut diagnosis in 44 patients, including 2 repeat biopsies; the success rate was thus 86% of all biopsies performed. 7 attempts (14%) did not yield useful material as the lesions were too small (diameter below 2.5 cm) or were not penetrated. In 35% of all biopsies small pneumothoraces were observed after a few hours. In two cases transitory hemoptysis occurred.

摘要

新型Vacu-Cut活检针与以往类型不同，其操作更简单，能产生更强的真空以提取组织芯。这种真空是通过一根探针穿过气密密封膜抽出而产生的。该器械是一根空心针，内有切割刃，直径为0.95毫米。49例怀疑有肺实质病变的患者在X线监测下经皮进行活检。活检材料使44例患者得到明确诊断，其中包括2例重复活检；因此，所有活检的成功率为86%。7次尝试（14%）未获得有用材料，原因是病变太小（直径小于2.5厘米）或未被穿透。在所有活检中，35%的患者在数小时后出现小气胸。有2例出现短暂咯血。
