8/15/2005

History of recurrent pneumonia

Surgical Report

• Intralobar Pulmonary Sequestration, treated with right lower lobectomy

• Two major arteries from the thoracic aorta• Large vein draining sequestered lobe

Bronchopulmonary Sequestration

own pleura

Intralobar Pulmonary Sequestration (ILS)

Characteristics• More common type• May present at any age• Generally as recurrent infection• No sexual predominance• Almost exclusively affects lower lobe• Arterial supply: descending aorta• Venous drainage: pulmonary veins

Etiology of Bronchopulmonary

Sequestration

• Accessory bud that forms caudal to lung buds• Traction theory• Postnatal formation

Pulmonary SequestrationComplications

• Heart failure

• Intralobar malignancy

Treatment of Pulmonary Sequestration

Symptomatic Disease
