Patients having lobar airway obstruction or consolidation usually have decreases of both ventilation and perfusion on lung scans. We report three patients in whom hypoxic vasoconstriction was apparently incomplete, resulting in a "reversed" ventilation-perfusion mismatch. Perfusion of the hypoxic lobe on the radionuclide scan was associated with metabolic alkalosis, pulmonary venous and pulmonary arterial hypertension in these patients.
患有大叶气道阻塞或实变的患者在肺部扫描时通常通气和灌注都会降低。我们报告了三例患者，其低氧性血管收缩明显不完全，导致“反向”通气-灌注不匹配。在这些患者中，放射性核素扫描显示低氧肺叶的灌注与代谢性碱中毒、肺静脉和肺动脉高压有关。
