Introduction:
Intrapleural rupture of pulmonary hydatid cyst (PHC) is a rare but dangerous complication. The purpose of this study was to report the characteristics of this form of thoracic hydatidosis and analyze the favoring factors.
Materials And Methods:
Between 1996 and 2011, 75 patients were operated in our department for PHC ruptured in the pleura (PHCP). The characteristics of this group were compared with those of a control group of 300 patients randomly selected from patients operated during the same period for PHC.
Results:
PHCP patients were younger than controls (23 years old vs. 27,56) (P=0.03) with male predominance (70% vs. 46%) (P=0.01). The PHCP were often located in the lower lobes (64% vs. 48%) (P=0.03). Anatomic resections were more used in control group (P=0.03) whereas decortication and pleurectomy were more frequently in PHCP (P=0.001).
Conclusion:
Young age, male sex, and basal locations of PHC promote their rupture in the pleura. Surgical treatment of these cysts requires less anatomic resections but more decortication and pleurectomy.
