Introduction: The aim of this study was tostudy the pattern of foreign-body aspiration inthe tracheobronchial tree as well as the successrate of rigid bronchoscopy in children admittedto the National Center for Maternal and ChildHealth, Mongolia during 2012-2016.Materials and Methods: In this crosssectionaldescriptive study, the required datawere collected from the medical reports ofall children under the age of 13 years withsuspected foreign-body aspiration who wereadmitted and underwent explorative flexibleand rigid bronchoscopy during 2012-2016. Thedata was retrospective viewed.Results: Among 40 patients with aconfirmed aspiration, 57.5% (23) were malesand 42.5% (17) were females. 42.5% were1-3 years old. The most common complaints(symptoms) of patients were non-productivecough (82.5%), wheezing (52.5%) andrespiratory distress (22.5%). The mostfrequently aspirated foreign bodies were nuts(peanuts). In total, 57.5% of foreign bodieswere lodged in the right bronchial tree. In 100%of cases, the foreign body was completelyextracted by bronchoscope. The majority ofcases were admitted more than 24 hours afterthe occurrence of aspiration, and pneumoniawas the most common complication. In X-rayfindings Golitsknyekhta Yakobsona’s symptomswere in 10 /25%/ cases.Conclusion: Patient history, especiallyinitial suspicion of aspiration, coughing,wheezing and respiratory distress, can behelpful in the diagnosis of foreign-bodyaspiration. All foreign bodies were removed bybronchoscope /100%/ without complications.In X-ray findings Golitsknyekhta Yakobsona’ssymptoms were in 10 /25%/ cases.

Introduction: Pulmonary sequestration(PS) is a cystic or solid mass composed ofnonfunctioning primitive tissue that doesnot communicate with the trachea-bronchialtree and has anomalous systemic bloodsupply. Pulmonary sequestration is a raredisease, of unknown etiology, representing0.1-6% of all structural lung diseases anddevelopmental malformations. We describea case of girl with pulmonary sequestration.Result: She has been admitted in ourhospital with left lower lobe mass. Fordifferential diagnosis we did X-ray, CTscanning, MRI of chest and angiography.In the X-ray had been detected retrocardiactriangular mass. CT scanning shown us massin the left lower lobe. Due to angiography wecan’t seen arterial supply. MRI demonstratedas like as X-ray, retrocardiac triangular mass.She had been gone under the electivesurgery: Left thoracotomy, resection ofpulmonary sequestration, drainage of pleuralcavity.During and after the surgery had notcomplication and she had been dischargedafter few days of post-operative treatment.She had been fully recovered.Conclusions: Pulmonary sequestrationis rare anormaly with multiple theoreticaletiologies. Due to high technological imaginginvestigations can take right diagnosis.The patient can be fully recovered afterthe surgical treatment. Intralobular typeis more difficult to resect the pulmonarysequestration.
