Application of transcatheter superselective arterial embolization for spinal tumorectomy / 局解手术学杂志

Objective To study the application of transcatheter superselective arterial embolization for the spinal tumorectomy preopera-tive.Methods From January 2009 to September 2015,the data of 65 patients with spinal tumor were collected.Before operation,all the pa-tients had been performed the transcatheter superselective arterial embolization by Seldinger technology,the embolization effect and the blood loss volume were recorded.Results The pathological vertebral body of 62 patients were significantly dyed and the tumor-feeding artery were obvious.But no obvious tumor-feeding artery and the tumor dyeing was found in 3 cases.The tumor-feeding artery positive incidence of angi-ography was 95.3%(62/65).All cases intubation was successful but one.After embolization, the pathological vertebral body was removed completely.The blood loss volume was 500-3 000 mL,with an average (1 400.65 ±230.62) mL.Conclusion The transcatheter superse-lective arterial embolization could reduce the blood loss in spinal tumorectomy and the operation risks,and increase the possibilities of radical resection,which is an effective preoperative intervention.

Clinical value of CT guided transthoracic core needle biopsy in diagnosis of pulmonary peripheral lesions / 第三军医大学学报

Objective To assess the clinical diagnostic value of CT guided transthoracic core needle biopsy (TNB) in patients with pulmonary peripheral lesions. Methods The pathological findings, follow up results, mass size, complications due to paracentesis, and other examination results in 223 patients with pulmonary peripheral lesions undergoing TNB were analyzed retrospectively. Results The positive predictive value of malignant lesions was 100%. False negative was found in 3 cases. There was no false positive of malignant lesions in all the cases. The sensitivity and specificity were 93.6% and 100%, respectively. The negative predictive value of benign lesions was 94.8%. There was no significant difference in the satisfaction rate of multiple biopsy between the large and small nodules. The satisfaction rate of a single biopsy of the large nodule was significantly better than that of the small nodule ( P

The diagnostic imaging and interventional therapy of hepatic angiomyolipoma associated with tuberous sclerosis / 介入放射学杂志

Objective To evaluate imaging diagnosis, differential diagnosis, surgery and interventional therapy of hepatic angiomyolipoma associated with tuberous sclerosis.Methods Clinical features, imaging appearances and interventional therapy for 2 cases of HAML in TS were retrospectrively analyzed. Results The features of HAML in TS are as following:(1) Two cases were female with no history of hepatitis and hepatocirrhosis, liver function test and alpha feto protein were normal. (2) the tumor was shown as a multiple hyperechoic mass with sharp margin on ultrasonography; well defined, fat density and intensity mass on computerized tomography (CT); hypervascular mass with early drainage of hepatic vein and tumor staining on angiography. (3) One case underwent interventional therapy. After 42 month follow up, the tumor was found to be diminished in size. Another case was under monitored with only the enucleating of left renal mass. The hepatic tumor showed no change after 10 months.Conclusions The imaging appearances of HAML in TS are relatively characteristic. Superselective arterial embolization is an effective treatment for HAML in TS.
