Three-dimensional Reconstruction Identifies Misaligned Pulmonary Veins as Intrapulmonary Shunt Vessels in Alveolar Capillary Dysplasia

Abstract

Alveolar capillary dysplasia (ACD) with misalignment of pulmonary veins (MPV) is a lethal neonatal lung disease. Death from ACD/MPV is caused by hypoxia, but the role of the MPV is unknown. Using 3-dimensional reconstruction of ACD/MPV lung tissue, we report that the veins in MPV are intrapulmonary shunt vessels, and speculate that MPV contributes to the poor prognosis.
