[Should Doppler echography in the diagnosis of the extra-cardiac sites of atherosclerosis be routine in patients with coronary disease? Apropos of 248 cases]. / La recherche, par échographie-doppler, des localisations extra-cardiaques de l'athérosclérose chez le coronarien doit-elle être systématique? A propos de 248 observations.

Doppler ultrasound investigation of cervical and aorto-iliac arteries, performed in 248 patients investigated by coronary angiography (including 80% with coronary heart disease: 23% single-vessel, 23% two-vessel and 34% three-vessel disease) confirmed the frequency of dissemination of the atheromatous process (in the cervical vessels: non-stenotic atheroma: 45%, significant single- or multi-vessel stenoses: 16%, in the aorto-iliac vessels: non-stenotic atheroma: 32.8%, significant stenoses: 17.2%), which has been known for a long time. The unreliability of clinical examination, the reliability, safety and low cost of ultrasound, the discovery of a considerable number of critical, potentially dangerous arterial lesions, some of which may require a surgical procedure or angioplasty (3.4%), the value of assessing, either before coronary angiography or before cardiac surgery, certain specific arterial territories such as the aortic bifurcation and subclavian vessels, justify systematic use of this examination in coronary patients, particularly before coronary angiography and always before coronary surgery.
