摘要：
FIELD: medicine.SUBSTANCE: invention describes a method for evaluating a surgical risk in the patients with atherosclerotic occlusion of a femoropopliteal tibial segment involved in critical ischemia, involving making a point assessment of cardiovascular comorbidities, wherein each risk factor is assigned with a fixed score as follows: age of over 70 years old - 1 point, acute cerebrovascular accident or transient ischemic attack in the past medical history - 2 points, postinfarction cardiosclerosis - 1 point, left ventricular ejection fraction of 46% to 50% - 2 points, left ventricular ejection fraction of 41% to 45% - 4 points, left ventricular ejection fraction of 40% or less - 6 points, ischemic heart disease: chronic coronary insufficiency of 1st functional class - 1 point, ischemic heart disease: chronic coronary insufficiency of 2nd functional class - 2 points, ischemic heart disease: chronic coronary insufficiency of 3rd functional class - 7 points, paroxysmal atrial fibrillation/flutter, ectopic rhythm, frequent (>5 a minute) auricular extrasystole - 3 points, persistent atrial fibrillation/flutter - 2 points, ventricular extrasystole >30 an hour - 1 point the total score is derived a surgical risk level is evaluated if the total score is 8 or more, the high surgical risk is stated, and an endovascular intervention is recommended if the total score falls from 0 to 3, the low surgical risk is observed requiring a bypass surgery, whereas the total score ranging from 4 to 7 means the moderate surgical risk, wherein both techniques of arterial repair are possible.EFFECT: invention provides the more reliable evaluation of the surgical risk in the patients with atherosclerotic occlusion of a femoropopliteal tibial segment involved in critical ischemia for the purpose of choosing the arterial repair technique - either an endovascular intervention, or a by-pass surgery, as well as a simplicity, accessibility and objectiveness of evaluating the surgical risk in the
