Clinical Outcomes of Transarterial Embolization in the Treatment of Pulmonary Sequestration

Purpose To assess the safety and efficacy of transarterial embolization (TAE) for pulmonary sequestration (PS). Methods A single-center, retrospective study was conducted from March 2013 and December 2020. Patient characteristics, laboratory/imaging, complications, and the TAE procedure were reviewed. Results We report 11 symptomatic patients with PS successfully treated by TAE. The aberrant supplying arteries were embolized, and there were no immediate complications. One to three days after TAE, patients complained of mild chest pain ( n = 4), moderate chest pain ( n = 3), and low-grade fever ( n = 1). Chest pain symptoms were completely resolved after 2–4 days. One patient with PS and bronchiectasis required thoracoscopic resection due to continued symptoms. The remaining 10 patients showed disappearance of chest pain and hemoptysis and decreased lesion size at 2 weeks and 3 months, with a clinical success rate of 90.9%. Conclusions TAE may be a feasible alternative treatment for pulmonary sequestration.
