DEAR DOCTOR K: I am scheduled to have an angioplasty next week. The doctor plans to insert the catheter through my wrist. Is there some advantage to doing it through the wrist rather than the thigh?
DEAR READER: Angioplasty is a procedure used to open a narrowed or blocked artery. Angioplasties are usually done to open up blocked coronary arteries -- the blood vessels that provide blood to the heart muscle. The blocked coronary arteries lie deep within the chest.
