The collapsed vein is a common result of the use of chronic intravenous injections. They are very common where injection conditions are less than ideal, as in the context of drug abuse.
The venous veins may become temporarily blocked if the internal venous lining swells in response to repetitive or irritated injuries. This may be caused by needles, substances injected, or donated plasma. After the swelling subsides, the circulation will often become established.
Permanent venous collapse occurs as a consequence of:
- Long-term injection
- Repeated injections, especially with blunt needles
- Bad techniques
- Injection of substances that irritate veins; in particular, liquid methadone injections intended for oral use.
Smaller venoms may collapse as a result of too much suction being used when pulling back against the syringe plunger to check that the needle is in the blood vessels. This will pull the side of the vein together and, especially if they are inflamed, they may stick together causing the veins to block. Removing the needle too soon after the injection can have a similar effect.
Torn veins may never recover. Many small blood vessels are made by the body to circulate blood, but they are not sufficient for injections or infusions.
