Intralobar sequestration of the lung in an adult (type 1 of Pryce). Treatment by coil embolization

A 34 year old patient presented with recurrent hemoptysis. A chest radiogra ph was normal. Helical CT angiogram of the chest with tridimensional recons tructions demonstrated an intralobar pulmonary vascular sequestration Pryce I-type of the right lower lobe. The angiography confirmed the diagnosis sh owing a large feeding artery arising from the coeliac trunk. An embolizatio n of the feeding artery using metallic coils was performed. Transient pulmo nary infarction occurred immediately after treatment. At two years follow-u p, the patient remains asymptomatic. Percutaneous embolization of this rare pulmonary vascular malformation is an alternative to surgical treatment.
