The literature for Zyplast says that injection into a blood vessel must be avoided, as this can cause necrosis. How does the doctor ensure that he won't be injecting into a blood vessel? Can this be done by aspiration?
How Do Doctors Avoid Zyplast Injection on the Blood Vessel?

Avoid vessels by Injecting Superficially
Zyplast injections are placed superficially, well above the larger caliber vessels. There is one area that may be a bit dangerous for Zyplast injections: the glabellar area, which is in between the eyes. There was at least one report of blindness in a patient from an injection into an artery feeding into the retinal artery. This area is one not usually treated in standard Zyplast treatments though. A good injector will know to go slowly, and superficially in this area.
Trust your doctor's judgement on proper placement of collagen
Zyplast, which is collagen, is injected intradermally which is into the dermis of the skin. It is very difficult to hit a large blood vessel when done properly and by a trained physician since most large vessels are under the skin in the fat layer and deeper. You have very little to worry about.
