Objective To evaluate diagnostic value and analyze the complications of the lung nodules by 64 slice CT guided percutaneous thoracic biopsy(PTB)with coaxial technique.Methods The clinical data of 63 patients with lung placeholder in coaxial line casing biopsy under CT guidance were retrospectively analyzed.After CT positioning,16G coaxial trocar rapidly passed through the pleura,the tip to the edge of the tumor or pathological lesions,pulled out the needle core,the coaxial sleeve in 18G semi automatic biopsy needle,the materials were multi-angle cuted and sent to the pathology examination,the positive rate and the incidence of complications were analyzed.Results In 63 cases of lesions under CT guidance,the success rate of drawing materials was 100.0%,the pathological diagnosis rate was 88.9%.Intraoperative and postoperative complications occurred in 18 cases,the incidence rate was 28.6%,among them 9 cases of pneumothorax(14.3%),pulmonary hemorrhage in 8 cases(12.7%),hemoptysis in 1 case(1.6%),no severe adverse reaction was observed.Conclusion Multi slice CT guided percutaneous coaxial biopsy has the advantages of simple operation,high diagnosis rate,less complications,low risk,it can be promoted in hospitals.

Objective To compare the efficiency and safety of aspirin-dipyridamole and warfarin in the prevention of thromboembolism in patients with nonvalvular atrial fibrillation(NVAF)and high risk factors.Methods One hundred and forty NVAF patients with high risk factors were randomly divided into two groups.Warfarin group[78 cases international normalized ratio(INR)2.0-3.0,for the patients older than 75 years,INR ranging from 1.6 to 2.5]and combination group(62 cases received aspirin 160 mg once every day plus dipyridamole 160 mg 3 times every day).The incidence of death,thromboembolism(including stroke and peripheral arteries embolism)and hemorrhage events were observed.Results Followed-up 12-28 months.In warfarin group,3 cases lost,2 cages had stroke,2 cases suffered from serious bleeding events,6 cases had minor bleeding events.In combination group,2 cases lost,6 cases had stroke,and 2 cases suffered from peripheral arteries embolism events,3 cases had minor bleeding events,but no serious bleeding events occurred.The incidence of thromboembolism in warfarin group wag,lower than that in combination group[2.7%(2/75)vs 13.3%(8/60),P<0.05].There was no significant difference of the bleeding rate between the two groups[10.7%(8/75)vs 5.0%(3/60),P>0.05].Conclusions Warfarin anticoagulative therapy is more effective than aspirin and dipyridamole antiplatelet dual therapy for the prevention of thromboembolism events in patients with NVAF and high risk factors.The major bleeding events in warfarin group occurs in patients with INR>3.0,so under intensive monitoring(INR 2.0-3.0),warfarin therapy is effective and safety.
