Contrast-enhanced ultrasound (CEUS) can distinguish between central lung cancer and atelectatic lung tissue. The aim of this study was to explore the clinical value of CEUS for biopsy in patients with central lung cancer with obstructive atelectasis.
One hundred and twelve patients were selected and CEUS was performed to display central lung cancer and atelectatic lung tissue. The front edge of central lung cancer was punctured with a needle, avoiding the necrotic area, under the guidance of CEUS.
All of the 112 lesions were diagnosed with a clear central lung cancer mass and atelectatic lung tissue. In 104 cases, the central lung cancer mass presented with a "slow-in and fast-out" pattern compared to atelectatic lung tissue. In eight cases, the central lung cancer mass presented with a "fast-in and fast-out" pattern compared to atelectatic lung tissue. The mean number of punctures was 2.6, and the success rate of puncture biopsy was 98%. Of the 112 patients, six cases had hemoptysis during the procedure and 10 patients had bloody sputum in the postoperative period. No complications were found in the other cases.
CEUS has important clinical value for needle biopsy of central lung cancer with atelectasis.
超声造影（CEUS）可区分中央型肺癌与肺不张组织。本研究旨在探讨CEUS在伴有阻塞性肺不张的中央型肺癌患者活检中的临床价值。
选取112例患者，行CEUS以显示中央型肺癌及肺不张组织。在CEUS引导下，避开坏死区域，对中央型肺癌前缘进行穿刺活检。
112个病灶均诊断为明确的中央型肺癌肿块及肺不张组织。104例中，中央型肺癌肿块与肺不张组织相比呈“慢进快出”模式。8例中，中央型肺癌肿块与肺不张组织相比呈“快进快出”模式。平均穿刺次数为2.6次，穿刺活检成功率为98%。112例患者中，6例在操作过程中出现咯血，10例在术后出现血痰。其他病例未发现并发症。
CEUS在伴有肺不张的中央型肺癌穿刺活检中具有重要临床价值。
