Just a quick one. I have had this happen to me a couple of times before and thought it somewhat self-explanatory so I never bothered to post about it. However, recently I am unsure as to whether my initial assumptions were correct and hoped to probe the orifice of your collective and substantial knowledge (apologies for the disturbing metaphor). I am fully versed and educated on the mechanisms behind veins collapsing, be it from repeated trauma and physical damage to the same small area or the repeated introduction of highly caustic or otherwise irritating/damaging substances into the vein.
But is it possible to collapse a vein without actually puncturing it? Or at least, without recently puncturing it?
i.e. Somebody goes to administer ~100mg/1mL heroin ascorbate solution into their cephalic vein (which has been used before, albeit very rarely and not for some time, with no problem) but for one reason or another, misses my a minuscule distance. They do not realise and subsequently inject 1mL of the aforementioned solution as an unintentional bolus right next to the vein in the arm. There is a degree of swelling, burning rash and discomfort (all typical for a miss of this type) but here is the thing. The vein, which was not punctured or touched remains forever more - unusable.
It is that the damage to the outer wall of the vein by the acidic solution caused it to swell and subsequently seal itself shut, causing collapse? Or similarly, the surrounding tissue affected by the miss, for want of a better term, squashes the vein shut and causes it to collapse.
I would be immensely grateful for any knowledge or insight into the matter. Many, many thanks!
