Hemianomalous pulmonary venous connection of the left lung surgically corrected.

Hemianomalous pulmonary venous connection is a rare congenital abnormality that leads to significant left-to-right shunt and complications related to that. Earlier surgical correction of this disorder was associated with the problem of stenosis at the anastomotic site with the left atrium. We describe the diagnosis of this abnormality in a 24-year-old woman and present the details of surgery to avoid the stenosis at the site of anastomosis.
