Tratamiento del secuestro pulmonar en niños : resección quirúrgica versus embolización endovascular.

Abstract

Introduction: Pulmonary sequestration is a lower respiratory malformation of the tract, which consists of nonfunctional mass of lung tissue without communication with the tracheobronchial tree and the blood sup ply from one or more aberrant systemic arteries. This stuyd aimed to analyze the outcomes of pediatric patients with pulmonary sequestration treated with surgical resection (thoracotomy, vid-eaossisted thoraco- scopy) or endovascular embolization. Methodology: a descriptive, observational, retrospective, cros-s ectional study in a tertiary pediatric hospital in Ecuador from January 2017 to December 2022. Data were collected from chart review. Results: 9 patients under the age of 18 were included, with a diagnosis of pulmonary sequestration, six fe males and three males, five were treated with surgery, 4 (44%) by thoracotomy and 1 (11%) by vid-eaossisted thoracoscopy, 4 (44%) with endovascular embolization, the mean age of patients who underwent surger was 41.36 months (range: 0.-1144 months), and of those who underwnet embolization was 12.9 months (range: 0.6-41months). One patient died six days after the surgical resection of the pulmonary sequestratio by thoracotomy secondary to pulmonary hypertension due to his underlying heart disease. One patien treated with endovascular embolization developed a decrease in pedal pulse, which resolved 24 hours afte starting streptokinase. Conclusion: In this study, surgery and endovascular embolization were safe procedures; however, no signif icant differences were found between both treatment options; more prospective studies are needed that include a large population sample of patients treated by endovascular embolization. .
