[Catamenial hemothorax: Results of 11 operated cases].

Objective: To report our therapeutic approach toward catamenial hemothorax.
Patients and Methods: This retrospective study from January 1994 to November 2018 concerned patients operated under general anesthesia for catamenial hemothorax. A posterolateral thoracotomy approach was implemented either directly or after primary videothoracoscopy. Six-month hormone therapy was systematically prescribed postoperatively. The result was assessed in terms of occurrence or non-occurrence of hemothorax upon resumption of menses after discontinuation of hormone therapy.
Results: Eleven patients were selected, with an average age was 32years (25-41). Catamenial hemothorax was associated with hemorrhagic ascites in 5 cases. Endometriotic plaques in the form of diaphragmatic fenestrations were found nine times and were resected (1 case) or covered by a synthetic non-absorbable patch (8 cases). Pleural symphysis completed the surgical procedures. The one hormone used was triptorelin. Mortality was zero. Mean postoperative hospital stay was 10.24days and mean follow-up was 3.5years. One patient was lost to follow-up at 3months. One hemothorax recurrence was observed after discontinuation of hormone therapy at 4months [1], and repeated pleural punctures were carried out while awaiting revision surgery. The five cases of ascites recurred and the patients were monitored in the gynecology unit.
Conclusion: In patients suffering from catamenial hemothorax with diaphragmatic fenestrations, we recommend phrenoplasty using synthetic patches associated with pleural talcage and 6-month complementary concomitant hormone therapy.
