Q33.2
Sequestration of lung
Clinical Classification Guidelines
Medical Intelligence & Overview
Lung sequestration, classified under ICD-10 code Q33.2, is a rare congenital condition where a portion of lung tissue is abnormal and separated from the normal lung structure. This separated tissue receives blood supply from abnormal arteries and does not perform the typical functions of healthy lung tissue. Typically present from birth, lung sequestration can lead to health complications if not properly diagnosed and managed.
Causes & Symptoms
Clinical Causes: Developmental anomaly during fetal lung formation Aberrant blood vessel formation supplying abnormal lung tissue Potential genetic factors influencing lung development Associated congenital conditions, such as congenital pulmonary airway malformation Previous intrauterine infections or exposures may influence severity
Key Symptoms: Recurrent respiratory infections, often in the affected lung area Chronic cough Shortness of breath or difficulty breathing, especially during physical exertion Chest pain or discomfort Fever during infection episodes Asymptomatic cases diagnosed incidentally through imaging Coughing up blood in severe cases
Diagnostic & Treatment
Diagnosis Path: Imaging studies, primarily chest X-rays to identify abnormal lung tissue Computed tomography (CT) scans provide detailed images of lung anatomy and blood supply Magnetic resonance imaging (MRI) may be utilized for better tissue characterization Angiography to visualize abnormal blood vessels supplying the sequestrated tissue Histopathological examination after surgical removal may confirm the diagnosis
Treatment Protocols: Surgical resection of the sequestrated lung tissue is the primary treatment to prevent recurrent infections and other complications Preoperative imaging studies guide surgical planning Antibiotic therapy to treat or prevent infections prior to surgery Regular follow-up post-surgery to monitor lung function In asymptomatic cases, close observation may be considered if there's no evidence of complications
