Transarterial embolization of intralobar pulmonary sequestration in adult patients: A case series.

Abstract

Pulmonary sequestration is a malformation of lung tissue such that a zone of pulmonary parenchyma exists in isolation from the bronchopulmonary tree. This condition is typically treated with surgical resection, but an increasing number of sequestrations are being treated with arterial embolization. We report interventions that were performed at two institutions on patients 53-70 years old. One patient presented with chronic cough and the two other patients presented with hemoptysis. Two of the cases were managed solely by endovascular embolization of the arteries supplying the pulmonary sequestration. In one patient, embolization was performed to debulk the sequestration, followed by surgical resection. These cases suggest transcatheter embolization may be an effective treatment in adult patients with symptomatic pulmonary sequestrations.
