Side Branch Occlusion or Blocking By Multiple Stents

I understand what side branch occlusion is, but what about the possiblity of stenting somebody so much in, for example, the LAD that the wire meshes overlap and restrict of significantly block the sepatals and diags?  I have heard of spontaneous recanalization, what exactly is this and would it apply to a case like this?  It just seems to me that there has to be a limit to the number of stents one can place within a given artery (stents within stents within stents, etc.).  I would even submit that a single re-stenosis event could occlude a side branch - is this not possible,a nd what would the consequenes be if it did occur?  Thanks!

Septals and large diagonals are large enough where a single, maybe even two overlapping stents won't compromise.  Of course, that it typically decided by the interventionalist based on the angiogram.  Typically, if there is no disease at the ostium (opening) of the artery there is usually no problem with jailing it.  If an artery does get jailed, the consequnce of that is that if tehre are inadequate collaterals chest pain and even a small infarction may develop.  Those are usually not problematic because those smaller branches that typically jail cover a very small myocardial territory and there are usually collaterals that often are able to supply blood to that area.  You are correct, that many times after initally jailing a side-branch, there is subsequent spontaneous. recanalization.
