Why do I have a prominent vein running down the bridge of my nose?

It’s important to distinguish between varicose veins and spider veins when choosing between laser therapy, sclerotherapy, and vein surgery. With two board certified vein specialists, our center uses a combination of visual examination, functional flow measurements, ultrasound, transillumination, and infrared light to map out vein networks prior to therapy. Lasers can be used to treat deep varicose vein insufficiency, vein perforators, and varicose veins. Sclerotherapy is ideal for spider veins and reticular veins. Whereas surgery is reserved for severely incompetent varicose vein segments.

Nasal veins are more common than you may think.  A picture would be helpful.  Nasal veins can be treated and this vein would not stop you from having a rhinoplasty or fillers.  It this vein was injured you would most likely get bruising and swelling.

I'm sorry but it is very difficult to answer this question without seen the pictures. You need to submit a picture.
Thanks

Hello peytonalexis56,
The vascular anatomy - that is, the configuration of arteries and veins  - of the nose is quite complex. There is a naturally occurring vein called the Angular Vein which runs along the sidewall of the nose, which may be unusually prominent in you. However, this is difficult to determine with certainty without a photo. This will not prevent you from undergoing a surgical rhinoplasty (nose job). As far as a nonsurgical rhinoplasty using filler, the angular vein is a structure that must be avoided during the procedure. I recommend a consultation with a plastic surgeon experienced in this procedure to assess whether or not it will be an appropriate and safe option for you. 
If your nose is hit, damage to the vein will likely result in a large bruise, but in the absence of other injury it will not likely jeopardize the survival of your entire nose.
