The effects of posture on the bruit and magnitude of the right-to-left shunt of a patient with a peripheral right lower lobe pulmonary A-V fistula are reported. A four-months-pregnant woman presented with an unexplained right hemiparesis. After delivery, a continuous murmur in the right lung base was detected. Subsequent studies showed that the loudest bruit and lowest PaO2occurred when the patient stood up, while the softest bruit and highest PaO2occurred when the patient lay in the right lateral decubitus position. These studies indicated that changes in the position of the diaphragm and mediastinum, form of the thorax, and/or volume of the lung had modified the known hydrostatic effects on pulmonary AV fistulous blood flow. |
