scar tissue formed 3 month after stent implant

[omi123]

husband at 42 had 5 vesel bypass 12 years ago. 3month ago stent placed due to scar tissue closing one of the bypass sites. 2 days ago stent that is three month old closed due to scar tissue.  Need to know if this will be a reoccurance at a regular basis?

For a perspective when a stent is placed in a blood vessel, new tissue grows inside the stent, covering the struts of the stent. Initially, this new tissue consists of healthy cells from the lining of the arterial wall (endothelium). This is a favorable effect because development of normal lining over the stent allows blood to flow smoothly over the stented area without clotting. Later, scar tissue may form underneath the new healthy lining.

In about 25% of patients, the growth of scar tissue underneath the lining of the artery may be so thick that it can obstruct the blood flow and produce an important blockage. In-stent restenosis is typically seen 3 to 6 months after the procedure; after 12 months have passed uneventfully, it is rare.
