Abstract:
A 72-year-old man, who had been treated pneumothorax 50 years ago, visited a physician complaining of dyspnea after thoracic sympathetic nerve block for postherpetic neuralgia. The patient was diagnosed as pneumothorax, and was consulted to our hospital. Clinical sign and the chest radiography suggested tension hemopneumothorax, and the chest drainage was immediately performed. Although bloody fluid of 1,100 ml was initially drained, no further increase was noted. The patient was discharged on the 21st hospital day.
