Hypaque or other water-soluble dye may be placed through the passage to ensure patency of the stent on fluoroscopy.

The dose from fluoroscopy of the stomach is much higher, approximately 50 mSv ( 14 times the annual background ).
33.
The passage of the catheter may be monitored by dynamic pressure readings from the catheter tip or with the aid of fluoroscopy.

A radio-opaque dye is administered through the catheter and a sequence of x-rays ( fluoroscopy ) is performed.

Another approach to treatment involves catheter-based embolisation, often preceded by phlebography to visualise the vein on X-ray fluoroscopy.
