ConclusionTranscatheter closure is a safe and effective interventional procedure in treatment of PDA using Amplatzer Duct Occluder and Porstmann Ivalon plugging.
Methods Fifty-six patients with serum creatinine level≥115μmol/L (groupⅠ) and 112 patients with normal creatinine level (groupⅡ)underwent coronary and/or renal artery stenting. Clinical status,angiographic findings,success rate of interventional procedure,and occurrences of cardiac events and renal failure were compared between the two groups.
Methods With interventional procedure under fluoroscopic guidance, 84 self-expanding metal stents were implanted orally in 67 patients of malignant gastroduodenal obstruction, including 27 with pyloric antrum obstruction, 26 with descending part of duodenum and further obstruction, 14 with gastroduodenal obstruction and stenotic gastrojejunostomy. 17 were taken reimplanted because of reobstruction afler 6 months.
Methods In all 12 cases,with interventional procedure under fluoroscopic guidance,12 duodenal self-expanding metallic stents were implanted through the mouth,11 percutaneous biliary self-expanding metallic stents were implanted through the holes of stents,1 outer draining was done.
Methods The X ray radiation dose at 1,2,3 meters from the X ray tube in front of and in the near of lead glass,plumbic suit were measured in 101 cases interventional procedure. The data were analyzed and evaluated.
Results:An interventional procedure success rate of 100% was archived with a mean systolic arterial pressure difference of 1 9 kPa between both upper limbs and normalization of radial pulses.
Thirty patients in observing group were received injection of 1mg penehyclidine hydrochloride before interventional procedure. Changes of heart rate,blood pressure and State-Trait Anxiety Inventory(S-AI) score 30 min after the injection were recorded and compared with that of the control group in the similar time phase.
Most patients with acute coronary syndromes are managed in hospitals without on-site angioplasty capabilities and often require transfer for an interventional procedure.
We disscuss effectiveness of endovascular stenting for cervical internal carotid artery aneurysm with intramural thrombus and the usefulness of a combination of the neuroradiological imaging before, during and after the interventional procedure.
Depending on the experience with the interventional procedure, percutaneous transhepatic cholangiodrainage should be considered as an alternative for treatment of symptomatic biliary leakage instead of immediate reoperation.
