WHAT IS RESTENOSIS?

 

Unfortunately, treatment to clear blockages often results in cell re-growth that can obstruct vessels again. This condition called restenosis occurs after 20 to 30 percent of PTCA procedures. (Source: The Merck Manual of Diagnosis and Therapy, Merck Research Laboratories, 1992). Repeat procedures are not uncommon and restenosis rates after repeat PTCA are as high as 50 percent.
