What risks are involved in angioplasty?

As with any medical procedure, angioplasty poses certain postoperative risks. Hence, it is important to discuss with your doctor and weigh the benefits versus the risks to decide whether the treatment is suitable for you.

You may develop an allergic reaction to the dye, stent, anesthetic or some other materials used during angioplasty. Other risks associated with coronary angioplasty include:

  • Bleeding, bruising or clotting at the point of catheter insertion or in the inner lining of the artery
  • Blood clots or scar tissue development in the stent that requires a repeat procedure
  • Damage to blood vessel or heart valve
  • Bursting of arteries due to elevated blood pressure
  • Irregular heartbeat or arrhythmia
  • Heart attack, stroke or death - the risk is greater when more arteries are involved
  • Damage to the kidneys caused by the contrast dye, particularly if there are preexisting kidney diseases
  • Re-blockage or restenosis of blood vessel
  • Infection
  • The artery may collapse or close again, particularly when stenting is not done

Your doctor will discuss each of these potential complications. The risks associated with an emergency angioplasty procedure are greater than the intervention performed under other circumstances. Most of these risks can be prevented, for example, use of a drug-eluting stent instead of a metal stent prevents the formation of scar tissue that can block the artery again. The risk of blood clots can be reduced by taking the prescribed medications.
