RESUMEN
Objective To investigate the value of high frequency 2-Dimensional and color Doppler flow imaging combined with mammography on the diagnosis of breast cancer. Methods 90 patients with breast cancer and benign breast lesions in 22 cases, respectively, separate by color Doppler ultrasound and mammography and their combination were compared. Results The blood flow signals were Ⅱ～Ⅲ grade(76.32% ) in breast cancer and benign breast lesions less blood flow to 0 ～Ⅰ grade ( 87.10% ); The detection rate of blood flow 89.48% in breast cancer were significantly higher than 38.71% in benign breast lesions ( x2 = 4.57, P ＜ 0. 05 ); 68 cases (75.5 % ) were diagnosed by mammography 38 cases(55.8% ) in diameter≤2. 0em were significantly higher than 30 cases(44.4% ) in ≤ 1.0 cm( x2 = 3.97, P ＜ 0. 05 ); The corresponding rate of Joint Inspection 85.7 % (96/112) was higher than the r 72.3% (81/112) in color Doppler ultrasound and 75.8% (85/112) in mammography ( x2 = 3.87, x2 = 3.85, all P ＜0. 05 ). Conclusion Color ultrasonography combined with mammography could raise diagnostic rate of breast cancer.Their combination is the best one of breast imaging examinations.
RESUMEN
8 years for 4 cases;5~8 years for 8 cases;3~5 years for 3 cases;less than 1 year for 1 case respectively.12 cases were followed up by color-sonography examination.The remaining 6 cases were followed by mail or phonecall.Results All cases reached clinical cure with relief or diasppearance of relevant symptoms and signs after 2~7 days PTA.88.9%(16/18) of the cases regained obility to labour or return to work.2 cases of the patients had lung infarction and heart failure immediately after the treatment,1 patient had recurrent stenosis and thrombosis after 1 year of PTA.Conclusion For treatment of membranous BCS,PTA should be the first choice.The majority methods of preventing recurrent stenosis and thrombosis are antithrombin application before PTA and adequate angioplasty during PTA.
