Interventional therapy of cervical esophageal malignant obstruction / 介入放射学杂志

Objective To explore the feasibility of microinvasive technique in high level malignantesophageal obstruction and to provide the palliative therapy that can't be dredged by traditional methods. Methods There were 39 patients suffered from high level esophageal obstruction,involving the segments from esophageal circular pharynx to 12mm below. Tube-reticular nitinol metal stents woven by single thread were placed in orally to dredge the esophagus under fluoroscopic guidance after repeated tolerant expanding performance through expandable catheter. Interventional chemical therapy were administrated through blood-supply vessels. Results Thirty nine patients were grafted with 46 high level esophageal stents. 34 patients accepted 156 times of interventional chemical therapy. All patients restored with fine residue diet without showing side-effects except slight pain and tolerant uncomfortable feeling. The survival rate of the patients with both interventional chemical therapy and stents was longer than those with stent therapy alone. Conclusion Cervical high level segment of esophagus shouldn't be the restricted zone in the management of inner-stents. Interventional chemical therapy showed tumor-inhibiting effect in the cervical malignant diseases.

Treating acute myocardial infarct with recombinant tissue-type plasminogen activator / 医药导报

Objective:To Observe the effect of recombinant tissue-type plasminogen activator (rt-PA) in treatment of acute myocardial infarct.Methods:Two groups of patients were observed.The subjects in the control group (35 patients) were treated with routine intervention,while those in thrombolysis group (15 patients) were treated with rt-PA in addition to the routine intervention.Results:There is a better outcome in the thrombolysis group as compared with that in the control group,in terms of length of angina relief,degree and length of EKG changes as well as the time for serum enzyme changes.The mortality rate in the thrombolysis group was significantly lower than that in the control group (P＜0.01).Conclusion:The rt-PA for thrombolysis in acute myocardial infarct patients can reduce the infarct size and improve the cardiac function rapidly as well as increase the survival rate.
