ABSTRACT
Objective To discuss the clinical application of feeding-artery embolization in treating massive hemoptysis.Methods The feeding-artery angiography was performed in 72 patients with massive hemoptysis.Based on the angiographic findings polyvinyl alcohol(PVA)or spring coil were selected as the embolization materials.The therapeutic results were retrospectively analyzed. Results Hemoptysis was completely controned almost immediately after the embolization procedure in 46 cases,while it was obviously alleviated in 13 cases.In 11 cases the hemoptysis disappeared completely after 2-4 times of embolization treatment,and in 2 cases surgery had to be employed.Conclusion Embolization of feeding-artery with PVA particles or spring coils is an effective and safe treatment for massive hemoptysis.The key point for decreasing reoccurrence is to occlude all feeding.arteries as far as possible.
ABSTRACT
Objective To evaluate the effect of transcatheter arterial chemoembolization(TACE)together with portal vein chemoembolization(PVCE)for the treatment of advanced liver carcinomas.Methods Forty-eight patients with liver carcinoma were randomly divided into two groups.Patients in study group(n=22)were treated with TACE together with PVCE,and patients in control group(n=26)were treated with TACE alone.Results Based on the postoperative CT findings and AFP levels,the effective rate of the study group was markedly higher than that of control group and the difference between two groups was statistically significant(P＜0.05).The volume of un-embolized liver tissue in the patients of study group was obviously increased after treatment. Conclusion TACE together with PVCE is superior to TACE alone in treating advanced hepatic carcinomas.The combination of TACE and PVCE can effectively increase the successful rate of surgical resection for the advanced hepatic carcinomas.
ABSTRACT
Objective To evaluate the clinical effect of interventional occlusion for atrial septal defect(ASD) with domestic occluder by X-ray in combination with echocardiography.Methods 38 patients with ASD were all implanted with domestic occluder.The imageological data before and 6 months after treatment were analysed and compared.Results There were no residual shunts after interventional treatment.The heart surface area,right inferior pulmonary artery diameter,the base lines of pulmonary cone,the diameters of pulmonary trunk and the degree of protrusion of pulmonary cone were all decreased after operation(P
