Resection of intralobar pulmonary sequestration after coil embolization of aberrant arteries: report of a case.

Pulmonary sequestration describes a rare congenital mass of nonfunctional pulmonary tissue with an aberrant systemic arterial supply. Conventionally, the mass is removed surgically, but this carries a risk of serious and potentially fatal hemorrhage from the aberrant arteries during the operation. We describe how we performed coil embolization of the aberrant arteries immediately before surgery to overcome this problem. Coil embolization is safe, feasible and effective in preventing intraoperative bleeding. This case is reported to introduce a new preoperative procedure for pulmonary sequestration.
