Figure 3. The diaphragmatic motion before and after
ethanol infusion into the vein of Marshall.
(A, B) Fluoroscopic images in the left anterior oblique (LAO) 45° view
before Et-VOM. Compared to the expiratory phase (A), both the right and
left diaphragms sufficiently moved downward in the inspiratory phase
(B). Bars indicate the motion of diaphragms. (C, D) After Et-VOM.
Although diaphragmatic eventration was not observed in the expiratory
phase (C), the movement of the left diaphragm with inspiration weakened
after Et-VOM (D).
