[en] Objective: To investigate the feasibility and efficacy of catheter-directed thrombolysis (CDT) for acute arterial occlusion of the limbs after percutaneous transluminal angioplasty (PTA). Methods: Over the recent 2 years, 14 patients with acute arterial occlusion of limb proved by arteriography were evaluated in this study. 10 patients were performed with PTA and thrombolysis by catheter-directed intraarterial urokinase for 3 to 7 days. 4 patients were performed with thrombolysis by catheter-directed intraarterial urokinase for 3 to 5 days. The treatment outcome and complications of this study were observed periodically. Results An overall improvement for arterial occlusion symptoms were obtained in the above 14 patients. Final angiograms revealed recanalization and complete dissolution of thrombus in 32 out of 38 arteries (84.2%). Doppler ultrasound, which were performed in 10 patients 4 weeks after interventional therapy, revealed patency in 26 out of 32 arteries performed PTA and catheter-directed thrombolysis. Conclusion: Interventional therapy, including PTA and catheter-directed thrombolysis for acute arterial occlusion of limbs were safe and effective. (authors)

[en] Objective: To evaluate the multislice CT-guided percutaneous vertebroplasty (PVP) in treatment of vertebral metastases. Methods: The efficacy and complications of CT-guided PVP in 25 patients with vertebral metastases were retrospectively reviewed. Results: The percutaneous paracentesis was successful in all 30 vertebrae in 25 patients. After PVP, the pain in all patients subsided gradually. Complete remission was obtained in 18 cases out of 25, and partial remission was accomplished in the rest 7 cases in one month after the intervention. In one case, bone cement (polymethy methacrylate PMMA) leaked into vertebral disc during the procedure while the treatment remained asymptomatic eventually. Conclusion: The multislice CT-guided PVP is a simple, precise, and safe interventional procedure, which is a practical treatment to improve the life quality of patients with vertebral metastases.
