Stenotrophomonas maltophilia

++

(stĕn′ ō-trō-fō-mōn″ as) A gram-negative, motile, strictly anaerobic bacillus of the family Pseudomonadaceae. It may cause pneumonia, meningitis, endocarditis, conjunctivitis, wound infections, and infections related to the use of central venous catheters. Trimethoprimsulfamethoxazole is used to treat infections with this organism. This species was formerly called Pseudomonas maltophila and Xanthomonas maltophila. SEE: illus.

stent

++

(stent) [Charles Thomas Stent, Brit. dentist, 1845–1901] 1. Originally, a compound used in making dental molds. 2. Any material or device used to hold tissue in place, to maintain open blood vessels, or to provide a support for a graft or anastomosis while healing is taking place.

++

airway s. A tube or catheter used as a scaffold to keep an airway open. It is used, e.g., to maintain the patency of a trachea or bronchus that has collapsed as a result of compression by neighboring tissues.

++

bare metal s. A vascular stent made of stainless steel or related materials. It is designed to hold an artery open with simple mechanical support. SEE: drug-eluting s.

++

covered s. A stent whose supportive lattice is coated with biocompatible fabric or plastic, e.g., Dacron, polytetrafluoroethylene, or silicone.

++

drug-eluting s. ABBR: DES. A stent coated with medications that it releases into surrounding intimal cells. It is designed to keep the lumen of an artery from closing both by holding the artery open and by retarding the growth of the vascular endothelium into the stent. SEE: bare metal s.

++

endoluminal s. A stent placed inside a tubular structure or organ.

++

endovascular s. A stent placed inside an artery or a vein.

++

esophageal s. A tube inserted into the esophagus to open a stricture.

++

intraluminal coronary artery s. A stent made of an inert material, usually metallic, with a self-expanding mesh introduced into the coronary artery. It is used to prevent lumen closure (restenosis) following bypass surgery and to treat acute vessel closure after angioplasty. SEE: illus.

INSERTION OF A CORONARY ARTERY STENT

++

(A) A balloon catheter with a collapsed stent is advanced to the location of a coronary artery lesion. (B) The balloon is inflated, which expands the stent and compresses the lesion to increase the artery opening. (C) The balloon is then deflated and removed, leaving the expanded stent in place to prevent the artery from closing.
