angioplasty

(ăn`jēōplăs'tē), any surgical repair of a blood vessel, especially balloon angioplasty or percutaneous transluminal coronary angioplasty, a treatment of coronary artery diseasecoronary artery disease,
condition that results when the coronary arteries are narrowed or occluded, most commonly by atherosclerotic deposits of fibrous and fatty tissue. Coronary artery disease is the most common underlying cause of cardiovascular disability and death.

. In balloon angioplasty a balloon-tipped catheter is inserted through the skin into a blood vessel and maneuvered to the clogged portion of the artery. There it is threaded into the blockage and inflated, compressing the plaque against the arterial walls. Frequent postoperative reclogging (restenosis) of the treated area has led to the use of alternative techniques such as laser angioplasty, which employs a laser to burn away or vaporize the plaque, and to the study of various drugs, gene therapies, and mechanical devices such as a stainless steel coil, or stent (most often now coated with a drug that inhibits restenosis), designed to hold the plaque back.

(medicine)
A procedure for alleviating blockage of an artery in which a balloon-tipped catheter is threaded into an artery to a point of obstruction and inflated to push the vessel open.

On the basis of our review, no trends of thicker or longer balloon dilation catheters producing better outcome are evident.
"Diagnostic and Therapeutic Technology Assessment (DATTA): Endoscopic Balloon Dilation of the Prostate." JAMA 267(8):1123-8, Feb.
In this study, clinical investigations focused on the surgical effect of an intact canal wall mastoidectomy and mastoidectomy combined with tympanostomy tube (TT) or balloon dilation eustachian tuboplasty (BDET).
Among them, 151 underwent bougination while 225 underwent balloon dilation. Regarding postprocedure symptomatic relief, the meta-analysis found no difference between the groups with [I.sup.2] = 0% (95% CI [-0.08, 0.08]).
An endoscopic sphincterotomy with balloon dilation was carried out and two Hem-o-lok clips were successfully removed from the bile duct with an extraction balloon (Figure 3).
(2) In a recent study by Levy et al, improvements after balloon dilation were noted in quality of life measures (SNOT-20) and sinonasal opacification (Lund-Mackay scores).
ESLBD would theoretically combine advantages of sphincterotomy and balloon dilation by increasing the efficacy at stone extraction while minimizing complications of either EST or EBD.
She and her associates retrospectively reviewed the medical charts of 26 patients with benign tracheal stenosis secondary to endotracheal intubation or tracheostomy who were treated with balloon dilation with or without laser bronchoscopy.
Thus, while some suggests that balloon dilation offers a less invasive, less expensive alternative to TURP, the issues of reobstruction with redilation and/or progression to the surgical option are concerns that must be addresses by further study.
For scarring airway stenosis, surgical resection was previously the gold standard;[2] however, interventional bronchoscopy treatments, such as balloon dilation, cryotherapy, laser therapy, and silicone stenting, have now been widely used to treat the disease,[3],[4] benefitting a large number of patients.
But when the distal bile duct was not sufficiently dilated for some patients, excessive balloon dilation beyond the diameter of the distal bile duct may increase the risk of perforation; therefore, we selected the EST.
A "combined" endoscopic technique (dilation-assisted stone extraction) is also used in current clinical practice to manage large CBD stones; in this technique, ES (full or partial incision of the transverse fold during ERCP) is associated with balloon dilation of the major papilla based on the final diameter of the distal bile duct (23).
