目的:探讨超声造影引导下经皮胸部穿刺活检的应用价值。方法:对26例影像学检查发现胸部占位性病变患者进行超声引导下经皮穿刺活检,术中先进行非造影条件下超声引导下穿刺,再进行造影条件下超声引导下穿刺,所取标本分别进行组织学检查,分析两组一次穿刺诊断成功率。结果:造影条件下一次穿刺诊断成功率为96.2%,非造影条件下一次穿刺诊断成功率为73.1%。两组穿刺诊断成功率比较,差异有统计学意义(P<0.05),非造影组穿刺失败的原因是所取组织为变性、坏死组织或正常肺组织。结论:超声造影可准确判断胸部占位病变坏死、液化区,区别肿瘤与含气不全肺组织,引导准确进行定位取材,提高一次穿刺诊断成功率,在胸部占位性病变穿刺活检中有重要的临床价值。
Objective: To evaluate the value of ultrasound-guided percutaneous thoracentesis biopsy. Methods: Twenty-six patients with thoracic space-occupying lesions underwent ultrasound-guided percutaneous biopsy. Thirty-two patients underwent ultrasonography under non-contrast imaging and under ultrasound-guided biopsy. Histopathological examination was performed respectively, and the success rate of one puncture diagnosis was analyzed. Results: The success rate of the first puncture diagnosis was 96.2% under the contrast condition and 73.1% under the non-contrast condition. The diagnostic success rate of the two groups of punctures was statistically significant (P <0.05). The reason for the failed puncture of non-contrast group was the degeneration, necrosis or normal lung tissue. Conclusions: Contrast-enhanced ultrasound can accurately determine the lesions in the thorax, liquefaction area, differentiate the tumor from the lungs with incomplete gas, guide the accurate positioning and drawing, and improve the success rate of primary puncture diagnosis. There is an important Clinical Value.
