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
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.
