  • Title: [Protective pneumothorax in CT-guided mediastinal puncture].
    Author: Wein BB, Dickgreber NJ, Günther RW.
    Journal: Rofo; 1997 Apr; 166(4):346-50. PubMed ID: 9198501.
    Abstract:
    PURPOSE: To achieve an extrapulmonary pathway for biopsy of mediastinal masses. METHODS: In 6 patients a protective, temporary pneumothorax was established before performing large-bore needle biopsies of mediastinal masses using a Verres-needle. RESULTS: 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. CONCLUSION: The use of protective pneumothorax allows cutting needle biopsies of mediastinal masses where aspiration cytology yields no secure specific diagnosis.
