“…Most patients with pulmonary sequestration have infectious manifestations, such as cough and expectoration, fever, chills, hemoptysis, and chest pain. Some patients have no obvious symptoms and are diagnosed only during physical examination 8,17–19 .

ObjectiveThis study aimed to summarize and analyze the characteristics of pulmonary sequestration to improve our understanding of this disease.MethodsBetween January 2019 and April 2023, the clinical data of 13 patients with pulmonary sequestration underwent surgical treatment at the First Affiliated Hospital of Gannan Medical University.ResultsThe male‐to‐female ratio was 4:9, the age was 0.5 to 60 years, and the average age was 38 ± 19 years. There were 10 and 3 cases of intralobar and extralobar pulmonary sequestration, respectively. Chest enhanced computed tomography (CT) and three‐dimensional vascular reconstruction showed that the abnormal blood vessels were derived from the descending thoracic aorta in nine cases and from other blood vessels in four cases. Three patients underwent thoracoscopic lobectomy, two underwent thoracoscopic segmentectomy, and eight underwent thoracoscopic wedge resection. All the patients successfully completed the surgery and were discharged postoperatively.ConclusionsSome patients with pulmonary sequestration exhibit no obvious symptoms. Patients with clinical symptoms are easily confused for pneumonia, bronchial cysts, lung abscesses, and lung tumors; therefore, patients with pulmonary sequestration are prone to missed diagnosis and misdiagnosis. Currently, enhanced chest CT combined with three‐dimensional vascular reconstruction can accurately show the course, branches, and relationship with the mass of the feeding artery. Routine pathological examination is helpful to further clarify the diagnosis of pulmonary sequestration. Minimally invasive thoracoscopic surgery is the preferred treatment for patients with pulmonary sequestration. Surgical resection is safe and feasible, and satisfactory results are typically obtained.

Lung sequestration is a developmental anomaly in the form of a separate non-functioning fragment of lung tissue that does not communicate with the bronchial tree and is supplied with blood by the aorta or arteries of the large circulatory circle. Lung sequestration is a developmental anomaly characterized by a separate nonfunctioning fragment of lung tissue that does not communicate with the bronchial tree and is supplied with blood by the aorta or arteries of the large circulatory circle. Lung sequestration accounts for 0.15%–6.4% of all lung malformations. This study presents a clinical case of a 7-month-old girl with extralobaric lung sequestration. The patient presented with complaints of cough; noisy, rapid breathing; and a history of gastroesophageal reflux. Gastroenterological pathology was excluded at the place of residence. During physical examination, wet wheezing was heard on both lungs, and the respiratory rate was 36 per minute. Chest X-ray showed a right-sided, upper-lobe pneumonia. Community-acquired right-sided, upper-lobe pneumonia, moderate form, was diagnosed. CT scan of the chest organs with contrast revealed a congenital malformation: tracheal bronchus and extralobar lung sequestration on the right. Indications for minimally invasive intervention were formulated. After surgical treatment, thoracoscopy showed an extrapulmonary sequester in the posterior hemithorax, with a feeding vessel from the thoracic aorta. Then, sequestrectomy was performed. In the postoperative period, positive dynamics was observed against the background of antibacterial, infusion, and symptomatic therapy. The patient was discharged in satisfactory condition. In children with long-term, recurrent lung infections, without positive dynamics against the background of conservative therapy and in the presence of respiratory disorders against the background of normal body temperature and absence of signs of inflammation in blood tests, congenital malformations of the respiratory tract should be excluded. Computed tomography with contrast enhancement and subsequent 3B reconstruction is the most appropriate method for diagnosing lung sequestration. Moreover, thoracoscopic resection of a separate nonfunctioning fragment of lung tissue is an effective minimally invasive surgical treatment method.
