ABSTRACT
Objective To evaluate the applications of transradial approach for endovascular interventions and to discuss the technical key points,indications,contraindications and advantages.Methods 230 patients underwent endovascular interventions via radial artery for 265 times.Technical success rate and related complications were recorded.Results Out of 265 times of interventions,260(98.1%) achieved success.No serious complications occurred except 3 local hematomas and during follow-up,weakened palpation of the radialartery in 8 cases and one arterial occlusion occurred,but without hand ischemia.Conclusion Transradial approach for endovascularinterventions is feasible and safe,and it has such advantages as high success rate,minimal complications,more comfort and less influence on treatment plan.
ABSTRACT
Objective To explore the clinical application and value of percutaneous treatment of pancreatic pseudocysts guided by CT.Methods The percutaneous external draining of pancreatic pseudocyst caused by various causes was performed under CT guidance in 29 cases, including 21 males and 8 females, age from 22 to 71 years, average (48.2?13.6) years. After the point, the angle,and the depth of puncture were measured on CT images, pseudocyst puncture and catheterization of external draining were made and followed up. Results 30 procedures of puncture in 29 lesions were done, the successful rate was 100%. Puncture path included frontal in 17 cases(18 times of puncture), lateral in 8 cases ; back in 4 cases, and 30 drainage catheters were placed. All cases were followed up except one case, follow up time ranged from 1 to 20 months [average (8 07?4 04) months]. Following disappearance of pseudocyst, catheters were extracted in 19 cases except 2 cases with pseudocyst recurrance. Follow up time from 4 to 14 months[average (8.29?4.03) months]. 5 cases had surgerical operations again after draining 1-4 months, 4 cases were still being followed up. The effective rate of therapy was 65.52%(19/29). Conclusion The technique of percutaneous catheter external draining of pancreatic pseudocyst guided by CT is mildly invasive and simple, and has high successful rate.
