Nghiên cứu đặc điểm hình ảnh của siêu âm Triplex trong chẩn đoán hẹp, tắc động mạch chi dưới đối chiếu với chụp cắt lớp vi tính 64 dãy

Lower peripheral arterial disease were more in the small and missed arteries, hemodynamically significant stenotic lesion in the downstair of popliteal is 37.8 percent, in the femoral popliteal is 20.7 percent, while in the pelvic is 10. 7 percent. In the large artery, atherosclerotic plaque distribution is mainly found in shallow femoral artery (accounting for 47.9 percent), and mostly hard atherosclerosis (accounting for 76.9 percent). Kappa coefficient provides a measurement of the diagnostic degreement between triplex USG with MSCT 64 slice. For the pelvic state, K= 0.64, in the femoral popliteal K=0.58 and the downstair of popliteal K=0.55. The measurement of the diagnostic degreement in lower peripheral artery is moderate with K=0.59. But with the main arteries of the lower extremity, it's as well as the common and shallow femoral artery with K= 0.64 and 0.85, with popliteal and anterior tibial artery, K=0.62 and 0.64.
