Coil embolization for pulmonary sequestration may serve as an alternative to surgical treatment: under which circumstances?

Although surgical intervention for pulmonary sequestration (PS) has traditionally been the primary treatment for adults, recent case reports have shown successful outcomes with coil embolization. However, information regarding the application of surgical versus coil embolization options in different patient groups remains limited. We report on two cases: both asymptomatic and without significant parenchymal damage, who underwent successful coil embolization for intralobar PS. After coil embolization, the first patient has been followed up for 4 years and the second patient for 1 year without symptoms. In asymptomatic adult PS patients without significant parenchymal damage, coil embolization may be utilized as part of the management of potential complications during observation, as well as a safe alternative to surgical treatment. These patients should be monitored at regular intervals post-procedure, and surgery should be considered if complications develop.
