Arterial hypoxemia during pregnancy caused by pulmonary arteriovenous microfistulas.
A patient developed symptomatic exercise-induced hypoxemia during pregnancy as a result of pulmonary arteriovenous microfistulas. Her symptoms resolved after pregnancy with spontaneous closure of the fistulas. Hormone-induced vasodilation is the probable mechanism.
