To achieve an extrapulmonary pathway for biopsy of mediastinal masses.
In 6 patients a protective, temporary pneumothorax was established before performing large-bore needle biopsies of mediastinal masses using a Verres-needle.
Transpleural, extrapulmonary access was easy to achieve. One patient developed a tension pneumothorax after biopsy which was drained by percutaneous small chest tube. Another patient showed mediastinal tumor bleeding through the biopsy needle. As a prophylactic measure the bleeding was stopped by injection of tissue glue through the biopsy needle.
The use of protective pneumothorax allows cutting needle biopsies of mediastinal masses where aspiration cytology yields no secure specific diagnosis.
实现纵隔肿物活检的肺外途径。
6例患者在使用Verres针进行纵隔肿物大口径针活检前建立了保护性临时气胸。
经胸膜的肺外入路易于实现。1例患者活检后发生张力性气胸，通过经皮小胸管引流。另1例患者活检针出现纵隔肿瘤出血。作为预防措施，通过活检针注射组织胶止血。
使用保护性气胸可在细针穿刺细胞学检查无法获得可靠的特异性诊断时，对纵隔肿物进行切割针活检。
