[Pleuro-pericardial cysts, treatment by video-assisted surgery].

Three cases of symptomatic pleuro-pericardic cysts were treated with video-assisted surgery. Complete exercises of the cysts was possible in all cases. The follow-up was uneventful and hospitalization was 4 to 5 days. Pleuro-pericardic cysts represent 5 to 10% of the mediastinal tumours. Clinical latency and a constantly benign course are characteristic features. In most cases, tomodensitometry confirms the diagnosis. The diagnosis may be uncertain only in symptomatic forms (atypical localization, high density on tomodensitometry). In these cases, video-assisted surgery is an interesting alternative to transparietal punction-evacuation or to exeresis via thoracotomy.
