The collapsed veins get temporarily occluded because the internal lining of the vein swells due to recurring injury. Once the swelling subsides, normal blood circulation gets re-instated.
Smaller veins collapse due to excessive suction when pulling back against the plunger of the syringe, to verify if the needle is in the vein.
Reviving Collapsed Veins
By and large, collapsed veins do not require any treatment, other than avoiding inserting the needle in them for a few weeks. Use different sites for the injection. Veins naturally heal. For a vascular disease, the most optimal venous treatment is compression stockings, leg elevation and fluid management. Certain surgeries for venous disease like placing stents can be done, but only in very severe cases.
Collapsed Veins Causes
Habitual use of intravenous injections damages the lining of the vein, both by tearing it and due to irritation caused by the injected drugs.
After the collapse of a vein, flow of blood is re-directed to other blood vessels, typically smaller / deeper veins. These veins do not have the same capacity as the collapsed vein; hence, they swell up too, causing a swelling of the affected limb. Because of poor circulation, minor cuts and puncture wounds from following injections become painful and heal very slowly.
- Chronic trauma from intravenous injections is the primary cause.
- Prolonged use of one vein for injection
- Using blunt needles
- Wrong method of intravenous injection
- Injection comprising of drugs that irritate the veins
- Excessive amounts of blood taken from the veins because of the suction that occurs with the pull of the plunger of the syringe.
- Swiftly removing the needle after giving the injection
- Peripheral vascular conditions like varicose veins
Symptoms of Collapsed Veins
Commonly seen symptoms of a collapsed vein are:
- Sharp pain because of tissue damage
- Cold sensation at the extremities, because of an obstruction of the flow of blood
- Discoloration of the skin
Collapsed Veins Treatment and Remedies
It is very vital that you understand the cause of the condition; depending up on that the treatment is determined.
A temporary collapse does not require any particular treatment, except that one will have to identify a new site for injections and avoid that particular site. Gradually, the swelling will subside.
Regrettably, when there is a permanent collapse, the vein cannot return to its original structure. Revascularization or formation of new blood vessels takes place. Ensure that the site gets adequate rest, so as to permit optimal vessel replacement.
For peripheral vascular disease, one needs to use compression stockings and must keep the leg elevated. Consume food low in fat. Rest the vein by rotating sites for the injection.
