[Clinical signs, symptoms, diagnosis and outcomes of patients with complicated lung hydatid cysts]

Hydatid cysts caused by the Echinococcus Granulosus and Multilocularis. Liver and them lungs are the most common sites of lodgment of it. Because the clinical symptoms, diagnosis and outcome of treatment are not well discussed, we want to discussion this problem. Survey of the clinical signs, symptoms, diagnosis and outcomes of patients with complicated lung hydatid cysts. We retrospectively examined 54 records of patients with ruptured lung hydatid cyst in 152 patients who were hospitalized in Rasht hospitals, since 1993 to 2005, and were surgically treated. Data collection tools were a predetermined review form; and findings are presented in relative frequencies tables. 54 cases 38[70.3%] were male. Age rang of patients was 4-63 years. Chief complaints of the patients were cough in 47 cases [87%], dyspnea in 42[77.8%], sputum in 37[68.5%], chest pain in 31[57.5%], and hemoptysis in 13[24%]. Most common lodgment of cysts in the lungs was right lower lobe in 38[57.5%]. Ruptures occurred in tracheobronchial tree in 39[73%], and in pleural space in 10[23%]. Complication after surgery occurred in 15 patients. Three patients [5.5%] were needed reoperation for treatment: bronchopleural fistula treatment in two cases and bilio-pleural fistula in one case. After surgical treatment, 53 patients [98.1%] were completely cured; recurrence occurred in one patient [1.9%] who treated with Albendazol. There was no hospital mortality. In endemic area all cystic lesions of lung must be ruled out for hydatid cysts; because some patients with lung hydatid cysts present complications: the cause of complication are, lately referring to physician and delay in diagnosis. Early treatment with medical and surgical approach recommended
