Until surgery: If you have a pheochromocytoma, you will be at risk for hypertensive crisis until the tumor is surgically removed. Before your operation, you will be given medication to gradually reduce your blood pressure along with frequent blood pressure checks to make sure that it is working.

Ionic, really?: Ionic intravenous contrast has been replaced by nonionic contrast. Nonionic contrast is safe to use in patients with or suspected of having pheochromocytoma or paraganglioma. The risk of hypertensive crisis due to ionic contrast should not last longer a few hours, but i could not find a reference to confirm this.
