Drug Eluting Stents for coronary arteries |
The use of metal Drug Eluting Stents (DES) presents some potential drawbacks. These include a predisposition to late stent thrombosis,
prevention of late vessel adaptive or expansive remodeling, hindrance
of surgical re-vascularization, and impairment of imaging with multi slice CT. That means we need some thing better than this in future. Are we there yet? However, it has been hypothesized that stents placed in many
atherosclerotic arteries may require only about 3–6 months of mechanical
integrity for scaffolding. Bioabsorbable or biodegradable stents that
provide mechanical support during vascular wall repair and then
harmlessly erode after the vascular wall has stabilized may eliminate
some of the potential chronic risks of permanent stents and may mitigate
the complexity of repeat stenting at the same site in the event of
restenosis.
