| 释义 | stent noun[ C ] medical specializeduk /stent/ us /stent/ a long thin object put inside a tube in the body, for example a blood vessel, so that its walls stay firm or so that body fluids can flow easily through it（植入身体导管内，例如用于防止血管壁粘合的）细长支架 Medical & surgical equipment AED arthroscope aspirator balloon catheter bioengineer catheter EKG endoscopic extracorporeal membrane oxygenation face mask FDG first aid kit magnetic resonance imaging stenting syringe syringe driver thermal blanket tomography tongue depressor ventilator a small piece of mesh that keeps any tube-like body structure open so body fluids can flow freely through it（植入身体内用于保证管道结构畅通的）小片网状物 Medical & surgical equipment AED arthroscope aspirator balloon catheter bioengineer catheter EKG endoscopic extracorporeal membrane oxygenation face mask FDG first aid kit magnetic resonance imaging stenting syringe syringe driver thermal blanket tomography tongue depressor ventilator Examples of stentstent Alternative options, such as implantation of stents, need to be evaluated. It was decided to proceed with surgical exploration and, ifwarranted, to place a further stent under direct vision. This is to allow for a 1520% elastic recoil in diameter but there is little shortening of the stent during expansion. Four stents were successfully placed in the pulmonary arteries and three in the aorta. On the first postoperative day, the stent in the orifice of the right pulmonary vein migrated to the descending aorta. This resulted in peal formation either because of low flow or because of subobstruction of the stent. Only mild granulomatous reaction was observed adjacent to the stent struts and degradation products. This approach prevents the stent from slipping off the balloon when being advanced through difficult turns, particularly in the smaller infants. The diameters in the middle of the stent were 6.9+ 1.7 mm immediately after implantation, and 6.9+2.1 mm in the follow-up angiographies, respectively. The stents were placed under general anesthesia in piglets (n=7) 1-3 days old, weighing 1.4-2.25 kg via a cutdown in the neck. Sequential balloon angioplasty then permitted gradual enlargement of the newly created channel, and subsequent placement of stents established a persistently wide venoatrial communication. In conclusion, implantation ofendovascular stents is an effective palliative or even therapeutic approach in complex coarctation. Three stents slipped over the balloon catheter during manipulation. A stent was found in the descending aorta proximal to the celiac artery. At autopsy, fibrous obstruction was noted proximal to the stent, and thrombus within the stent.
