[摘要] Diken et al.: “Distribution of calcifications of thoracic aorta in patients undergoing coronary artery bypass grafting” When patients need coronary artery bypass surgery, the vessels affected by coronary disease, [which impairs blood flow to the heart vessel,] are bypassed by graft vessels. In many cases, manipulation of the aorta, the body’s main artery, is necessary to attach grafts or insert tubes during the procedure. If the aorta is calcified, calcifications can come loose during manipulation and cause e.g. a stroke by occluding vessels in the brain. Analysing imaging of 443 patients, Diken et al. studied the distribution of calcifications in the aorta which were present in 67% of patients. They proposed a classification which can be used for patients undergoing coronary artery bypass surgery.
