Was your urine brown or tea colored soon after having an angiogram to check for a brain aneurysm?
An angiogram relies upon a contrast dye to make things more visible on the imaging study — whether your doctor is checking for an aneurysm or some other kind of blood vessel disorder or even a tumor.
The contrast agent that’s used is iodine-based. It “lights up” blood vessels. This way, a doctor can identify the telltale bulge of an aneurysm or the presence of a tumor (because they have their own rich blood supply).
“The contrast dyes used in angiograms today are not associated with color changes in your urine,” says Atif Zafar, MD, director of the stroke program at University of New Mexico Hospital and assistant professor of Stroke/Neurology at the UNM School of Medicine.
Why the brown urine?
If your urine is brown or the color of tea or cola – soon after your brain angiogram or at any time – you’ll need to alert your doctor to this.
There are over a dozen causes of this symptom, ranging from benign to life-threatening.
This article covers all of those causes.
