title: Ultrasonically guided needle aspiration biopsy in the diagnosis of advanced superior vena cava syndrome.
abstract: From July 1990, 11 cases with advanced superior vena cava (SVC) syndrome were undergone ultrasonically guided needle aspiration or biopsy. Ten cases were diagnosed by thin-needle aspiration cytology. Two cases with cytologic proven lymphoma and one case without cytologic diagnosis were undergone needle biopsy, and two of them were proven to be lymphoma. The diagnostic rate of aspiration cytology was 91.0% (10/11) and of aspiration biopsy was 66.6% (2/3). The diagnostic rate of combination of aspiration cytology and biopsy was 100%. For reducing the incidence of pneumothorax, we strongly recommend this two-stage procedure that needle biopsy was performed only when cytologic diagnosis was not conclusive. Only one case developed pneumothorax in performing needle biopsy. In conclusion, ultrasonically guided needle aspiration biopsy is a safe, convenient, and high-yield diagnostic procedure for selected cases of advanced SVC syndrome.
