超声造影在前纵隔肿物穿刺活检中的应用价值

目的 探讨CEUS在前纵隔肿物经皮穿刺活检中的应用价值。方法 79例前纵隔占位患者，其中39例穿刺活检前接受CEUS检查为实验组，40例仅接受常规超声检查为对照组，分析两组间取材次数、病理诊断率及病灶内坏死显示率。结果 实验组和对照组病灶内液化坏死显示率分别为66.67%（26/39）和22.50%（9/40），差异有统计学意义（P＜0.05）；实验组和对照组的病理诊断率分别94.87%（37/39）和77.50%（31/40），差异有统计学意义（P＜0.05）。实验组1例患者穿刺后皮下血肿，对照组未见严重并发症。结论 CEUS能够识别病灶内坏死区域和活性区域，提高活检穿刺的安全性、准确性和成功率。

The value of contrast-enhanced ultrasonography in anterior mediastinal mass biopsy

Abstract Objective To investigate the value of CEUS in percutaneous needle biopsy of anterior mediastinal masses. Methods 79 patients with anterior mediastinum, 39 of whom underwent CEUS before the biopsy were the experimental group, and 40 received only routine ultrasound as the control group. The number of samples and pathological diagnosis were analyzed between the two groups. Rate and rate of necrosis in the lesion. Results The liquefaction necrosis rates in the experimental group and the control group were 66.67% (26/39) and 22.50% (9/40), respectively, and the difference was statistically significant (P<0.05). The pathological diagnosis rates of the experimental group and the control group were respectively 94.87% (37/39) and 77.50% (31/40), the difference was statistically significant (P<0.05). The number of punctures in the experimental group and the control group were (2.05±0.32) times and (2.00±0.00 times), and the difference was not statistically significant (P>0.05). No serious complications were seen in either group. One patient in CEUS had a subcutaneous hematoma after puncture, and no serious complications were found in the control group. Conclusion CEUS can identify the necrotic area and active area in the lesion, and improve the safety, accuracy and success rate of biopsy.
