Objective To determine the location and degree of fallopian tube obstruction,providing a safe reliable and effective treatment. Method 50 infertile women with unilateral or bilateral fallopian tube stenosis, adhesion and obstruction were selected for this study, with ages range of 23 to 38 years. Selective salpingography was performed using co-axiol catheterization with micro-guide wire mechanism combined with recanalization, anti-inflammatory agents during the procedure and postoperative period. Results The rate of properly performed catheter and recanalization reached 92% and 68.7%, respectively. During the follow-up of one year, 23 cases (23/50, 46%) obtained ability of pregnancy. Conclusion Selective salpingography with fallopian tube recanalization is a minimally invasive method to treat tubal infertility. (J Intervent Radiol, 2006, 15: 290-292)

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.

With extensive application of interventional radiology technique, skilled and standardized manipulation of DSA is very helpful for interventional operations. It is introduced in this paper how to operate the Siemens dBA which is the first domestic one and settle with the problems met in routine work.

Objective To assess the usefulness of the DPF with Store Fluoro for interventional treatment. Methods Store Fluoro were performed in 187 cases and the dose was compared with that not using it. Results The doctor and the patients′ radiology dose and the volume of the contrast were all reduced. Conclusion The Store Fluoro plays an important role in interventional treatment.

Objective To investigate the imaging diagnostic value of ureter cysts.Methods The intravenous pyelogram(IVP), CT MRI and ultrasonic data of 17 cases of ureter cyst were analysed trtrospectively. Results All patients were correctly diagnosed preoperatively. The application of US and intravenous cystography may aid to improvement of diagnosis.Conclusion The combination of multiimaging modalities was proved to be of great value in diagnosis of ureter cysts.

The case of long-term complicated infectious mass on the inner thigh root after transobturator urethral sling is rare. This paper reported a case, who underwent a surgery of the "trans-obturator mid-urethral slings" for stress urinary incontinence 9 years ago. A mass on the root of the right thigh was found 3 months ago, accompanied with low fever. About 1cm tape was exposed on the front wall of the right side of the vagina. The patient underwent resection of the mass on the root of the right thigh and partial removal of the tape under spinal anesthesia. After one year’ follow-up, there was no significant change in urinary control ability compared with that before the operation.

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.

Objective To analyze the correlation factors affecting DSA picture quality and to investigate the DSA value and effectiveness in hepatic arteriography. Methods 36 cases with liver tumor were analyzed through femoral artery intubatton with Seldinger and had hepatic arteriography with RH catheter. Results In the 192 images of 36 cases,the percentage of first-rate image was 92.7%,the second-rate image (9/192) was 5.3%,the third-rate image (5/192) was 2%. Conclusion All of the second-rate images and the third-rate images which were handled with selective image postprocessing can improve picture quality and can reach diagnosis request.

Objective To analyze the role of CT scan in the diagnosis of maxilla sinus malignant tumor. Methods Data from CT scan in 17 patients were retrospectively analyzed. All cases were confirmed histologically. Results All cases manifested soft tissue mass in the sinus cavity and sinus wall bone destruction.The tumor could infiltrate out of maxilla sinus through destructive bone or nerve. Conclusion CT scan is an effective examination in diagnosis and evaluation of staging.

Objective To study the diagnostic value of imageology for pyelic carcinoma.Methods The accuracy of qualitative diagnosis and sensitivity were analyzed by comparing various imaging examinations in 19 patients with pathologically proved pyelic carcinomas.Results Irregular filling defect and hydronephrosis were seen in the renal pelvis and calyces on intravenous pyelography(IVP).On CT scan,when the tumor was small,soft tissue mass was in the renal pelvis and the calyces.When the renal parenchyma involved by tumors,the soft tissue masses with unhomogeneous density,liquefaction necrosis in the renal pelvis and the parenchyma were seen.On contrast-enhanced CT scan,enhancement from slight to moderate was found in the lesion.The lesions were detected by IVP in 9/12 cases,by BUS in 10/16 cases,by CT in 18/19 cases and by MRI in 3/3 cases.Conclusion IVP and CT are the first method of choice to diagnose the pyelic carcinoma,BUS can be used as a screening method.While in evaluating the tumor involving the parenchyma of the ren or distant metastasis,CT and MRI are superior to IVP.
