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.
ABSTRACT
Objective To study the therapeutic effect of percutaneous transluminial angiography (PTA) and expandable metal stent (EMS) on the treatment of Budd Chiari syndrome(BCS). Methods One hundred and twenty patients with BCS confirmed by color Doppler ultrasonography, inferior vena cava venography and hepatic veins venography. All the 120 patients underwent PTA and EMS. All the 120 patients were followed up for 6 to 108 months. Results The treatment results in 115 patients(95.8%) were satisfactory,and 5 cases had recurrent during follow up . Conclusions PTA with EMS is an excellent method to treat the cases of BCS with non long segment occlusion of IVC.
