A simple imaging procedure has been devised for patients with peritoneo-venous shunts when ascites reaccumulates and a decision must be made on whether or not to revise the shunt. We recently experienced a patient with reaccumulated ascites in whom obstruction of peritoneo-venous shunt was suspected. 5 mCi of 99mTc-phytate was injected into the peritoneal cavity and imaging of the abdomen was performed 1~30 minutes later. With a proper funtioning shunt, radioactivity in the liver and spleen were easily identifiable in this case. If the shunt is obstructed, tracer activity will remain in the pediotoneal cavity and thus can not be identifiable m the liver or spleen. Conclusively, radionuclide methods might be very useful for evaluation of peritoneo-venous shunt patency.

Therapy of pulmonary hypertension is limited by the low potency and adverse effects of current pulmonary vasodilators. The hemodynamic effects of nitroglycerin in human pulmonary hypertension are not clear. But some reported that nitroglycerin produced pulmonary venodilation at doses that do not affect the systemic arterial vasculature, so it may not decrease systemic arterial pressure, We administered nitroglycerin to 14 patients with chronic pulmonary hypertension. Nitroglycerin decreased mean pulmonary arterial pressure by 19%, pulmonary vascular resistance by 25% and systemic arterial pressure by 11%, but did not affect heart rate, cardiac out- put, pulmonary capillary wedge pressure and arterial oxygen tension. Among these patients, nitroglycerin was more effective in patients with moderate pulmonary hypertension(mean pulmonary arterial pressure: 30~49 mmHg) and there were no side effects during this study procedure. We conclude that therapy with nitroglycerin can be effective in patient with pulmonary hypertension, especially in those with moderate degree of pulmonary hypertension.
