The treatment is usually surgical (lobectomy). However, a less invasive approach with percutaneous embolization of the systemic artery can be considered as an alternative option.Methods: Retrospective study of the last 13 years of clinical cases of pulmonary sequestration with percutaneous treatment in a Radiology Department in Lisbon.Results: 4 patients were identified (average age 34, 50% male). Concerning smoking habits, only one patient did not smoke (mean of 10 pack year). Clinically, one patient presented with repeating pneumonias, and the other 3 patients with hemoptysis. In all cases diagnosis was obtained through angio-CT (mass or homogeneous opacity in the lower lobe with identification of an arterial systemic blood supply). Pulmonary malformations were identified in the right lower lobe in 3 patients (75%) and in the left lower lobe in one patient. Treatment consisted of percutaneous embolization of the affected systemic artery with metallic coils of various sizes depending on the vessels diameter (8mm, 5mm and 3mm). On follow-up (lasting from a couple of months to two years), all four patients had significant reduction of abnormal vascularization, resolution of symptoms and progressive reduction of the findings previously visible on angio-CT. There were no complications related to the technique in any case.Conclusion: Treatment with coil embolization should be considered in pulmonary sequestration with predominant vascular component, allowing a quick and safe treatment with low cost, morbidity and mortality.
