0 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 --
1 a small piece of mesh that keeps any tube-like body structure open so body fluids can flow freely through it --
At autopsy, fibrous obstruction was noted proximal to the stent, and thrombus within the stent.
A stent was found in the descending aorta proximal to the celiac artery.
Three stents slipped over the balloon catheter during manipulation.
In conclusion, implantation ofendovascular stents is an effective palliative or even therapeutic approach in complex coarctation.
Sequential balloon angioplasty then permitted gradual enlargement of the newly created channel, and subsequent placement of stents established a persistently wide venoatrial communication.
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.
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.
This approach prevents the stent from slipping off the balloon when being advanced through difficult turns, particularly in the smaller infants.
