目的探讨超声造影在引导炎性淋巴结穿刺取材中的应用价值。方法将患有浅表淋巴结肿大拟行穿刺活检的患者,随机分为A组(造影组)和B组(常规组)。比较两组中炎性淋巴结病例的取材效果和诊断准确率。结果 A、B两组分别有69例和76例淋巴结炎。A组超声造影呈显著增强区,病理显示为与病变相关的各种细胞增生区;无增强区,病理主要显示为不同类型的坏死灶。A组取材效果显著优于B组(平均秩次81.07vs 64.86,P<0.01);A组诊断准确率为95.7%(66/69),高于B组84.2%(64/76),差异有统计学意义(P<0.05)。结论超声造影可以对炎性淋巴结内的细胞增生区及坏死灶做针对性穿刺活检,有助于提高标本取材效果及诊断准确率。
Objective To investigate the value of contrast-enhanced ultrasound in guiding the extraction of inflammatory lymph nodes. Methods Patients with superficial lymph node enlargement were randomly divided into group A (angiography group) and group B (conventional group). Comparison of the two groups of cases of inflammatory lymph node extraction and diagnostic accuracy. Results A, B two groups were 69 cases and 76 cases of lymphadenitis. A group of CEUS showed a significant enhancement of the area, the pathology showed a variety of cell proliferation associated with the lesion; no enhancement area, pathology mainly showed different types of necrosis. The accuracy of group A was significantly higher than that of group B (mean rank 81.07 vs 64.86, P <0.01). The diagnostic accuracy of group A was 95.7% (66/69), higher than that of group B 84.2% (64/76) Statistical significance (P <0.05). Conclusion Contrast-enhanced ultrasound can detect the biopsy of cell proliferation and necrosis in inflammatory lymph nodes, which can help improve the quality of specimens and the diagnostic accuracy.
