Abstract:
Hypoxic pulmonary vasoconstriction is a unique response of the pulmonary circulation to hypoxia. It constitutes part of the self-regulatory mechanism by which pulmonary capillary blood flow is adjusted to alveolar ventilation for maintaining the optimal balance of ventilation and perfusion. In pathological conditions, hypoxic pulmonary vasoconstriction may occur as an acute episode or as a sustained response with pulmonary hypertension and vascular remodeling. We report a case of reversible pulmonary hypertension induced by acute hypoxic pulmonary vasoconstriction in an 18-year-old man with relapsed acute myeloid leukemia, complicated with severe anemia and pneumonia.
