| 目的 评价常规超声及介入超声对纵隔肿瘤的诊断价值。方法 对临床诊断前纵隔肿瘤的56例患者进行超声检查,并对其中46例进行超声引导下穿刺活检。结果 56例前纵隔肿块超声均能显示,显示率100％;纵隔肿瘤穿刺活检者获确切病理诊断的占73.0％(32/44),可疑诊断及不能帮助诊断者各占13.5％(6/44)。无并发症发生。结论 常规灰阶超声能对大多数前纵隔肿瘤作出定位诊断;实时超声观察能清楚地显示肿块与心脏大血管的关系,从而准确地引导穿刺活检,使超声引导下纵隔肿瘤的穿刺活检成为一项安全可靠、简便、价廉的技术。 |

| Objective To assess the diagnostic value of ultrasonography (US) and interventional US in mediastinal tumors. Methods Fifty-six patients who were clinically diagnosed anterior mediastinal tumors were examined with US and 46 tumors were performed biopsy with 18G or 16G needle under US-guidance. Results All 56 anterior mediastinal tumors were detected by US with a detection rate of 100%. A definite pathologic diagnosis was made in 32 of 44 cases (73.0%). The pathologic diagnosis was inconclusive and not achieved in 6 patients (13.5%), respectively. No complications of biopsy were found. Conclusion Real-time US could clearly show the relationship between the tumor and the heart or vessels, and enable accurate tissue sampling. US-guided percutaneous biopsy is a valuable method in the diagnosis of mediastinal tumors because it is easy to perform, safe, reliable and relatively cheap. |
