Objective To compare elasticity imaging and conventional ultrasound when applied to the diagnosis of benign and malignant breast tumors.Methods Totally 124 breast tumor patients (140 lesions) from some hospital were analyzed retrospectively,who were divided into a control group and an observation group according to ultrasound examination ways.The control group involved in 60 patients with 66 lesions undergoing conventional ultrasound examination,and the observation group had 64 patients with 74 lesions undergoing elasticity imaging.Pathological findings were considered as gold standard,and the two groups were compared on accuracy,specificity and sensitivity.Results Pathological detection found the accuracy,specificity and sensitivity of the malignant tumor in the control group were 85.00％,84.78％ and 84.85％ respectively,and the ones of the malignant tumor in the observation group were 95.83％,96.00％ and 95.95％ respectively.The two groups had significant differences between the accuracies,specificities and sensitivities (P＜0.05).Conclusion Elasticity imaging describes the size,shape,number,margin and etc of the breast tumor,and thus can enhance the accuracy,specificity and sensitivity for diagnosing breast tumors.

Objective To summarize the clinical efficacy of interventional treatment for lower extremity arteriosclerosis obliterans and its complications.Methods We analyzed sixty-nine patients with lower extremities arteriosclerosis obliterans undergoing interventional treatment from October 2011 to January 2013.During the same period,three patients were referred to us who suffered from the complications of interventional treatment.In these patients,eight were TASC ⅡA type,twenty-one were TASC Ⅱ B,twenty TASC Ⅱ C,and twenty-two TASC Ⅱ D lesions.All patients received CTA or DSA.Seventy patients were treated by interventional treatment,and two who had fractured stent underwent external iliacsuperficial femoral artery bypass grafting using artificial grafts.Results The technique success rate was 100％.The symptoms disappeared after surgery.During interventional treatment,one iliac artery ruptured,one patient suffered from arterial perforation and three patients suffered from distal embolization.Sixty-eight patients were followed-up for 9 ± 4 months.Conclusions Endovascular treatment has good early clinical efficacy.In order to reduce the incidence of complications,indication of interventional treatment should be controlled strictly and manipulation should be careful.
