A study was undertaken to evaluate the effectiveness of the blood patch technique in the prevention of pneumothorax after transthoracic needle aspiration biopsy. A total of 140 needle biopsies were performed with a coaxial system. Two groups of patients were defined according to whether or not autologous blood was injected into the introducing needle as it was withdrawn after needle aspiration biopsy. Fifty-two biopsies were performed with the blood patch technique (group A), while 88 biopsies were performed without the blood patch technique (group B). The frequency of postbiopsy pneumothorax was 28.8% (15 of 52 patients) in group A and 34.1% (30 of 88 patients) in group B. Chest tube insertion was required in 7.7% (four of 52 patients) in group A and in 9.1% (eight of 88 patients) in group B. There was no statistically significant difference in pneumothorax rate and chest-tube insertion rate between the two groups (P greater than .05). In this series of 140 biopsies, the blood patch technique failed to affect the rate of pneumothorax after transthoracic needle aspiration biopsy.
开展了一项研究，以评估血补丁技术在预防经胸针吸活检术后气胸方面的有效性。使用同轴系统共进行了140次针吸活检。根据在针吸活检后拔出引导针时是否向其中注入自体血，将患者分为两组。采用血补丁技术进行了52次活检（A组），未采用血补丁技术进行了88次活检（B组）。A组活检后气胸发生率为28.8%（52例患者中的15例），B组为34.1%（88例患者中的30例）。A组7.7%（52例患者中的4例）和B组9.1%（88例患者中的8例）需要插入胸管。两组之间的气胸发生率和胸管插入率无统计学显著差异（P大于0.05）。在这一系列140次活检中，血补丁技术未能影响经胸针吸活检术后的气胸发生率。
