Why are arteries closed after open heart surgery?
2 doctors weighed in across 2 answers
Many reasons: There are many reasons why arteries are closed after coronary artery surgery. Remember that surgery "bypasses" and does not remove blockages. Most importantly surgery does not chnage the medical problems which caused the blockages (such as cholesterol, diabetes, hypertension, smoking, obesity, and sedentary lifestyle) and unless these are addressed the arteries will continue to close.

They're not: Coronary arteries are bypassed with vein or other arteries to bring new blood beyond blockages.
