Dr. Capoccia and coinvestigators found a 21% incidence of new cerebral ischemia on diffusion-weighted imaging after stenting. (medscape.com)
Background and Purpose: Cerebral Venous Sinus Stenosis (CVSS) usually results in severe Intracranial Hypertension (IH), which can be corrected by stenting immediately. (benthamscience.com)
Efficacy of stenting in patients with cerebral venous sinus thrombosis-related cerebral venous sinus stenosis. (benthamscience.com)
Severe stenoses were also no more likely to cause 30-day emergent cerebral revascularization (HR 0.56, P=0.451) or asymptomatic subarachnoid hemorrhage (HR 0.01, P=0.446). (patientcareonline.com)
We describe our recent experience in the endovascular treatment by means of stent-assisted angioplasty with the aid of a filter cerebral protection device of eight patients presenting with radiation-induced carotid stenosis. (citationimpact.com)
Carotid angioplasty with cerebral protection can be performed safely in radiation-induced carotid stenosis with a high technical success rate. (citationimpact.com)

The Wingspan intracranial stent is another therapeutic option but there are limited data on the technical success of stenting and outcome of patients with 70% to 99% stenosis treated with a Wingspan stent. (nih.gov)

Venous Sinus Stenting for Low Pressure Gradient Stenoses in Idiopathic Intracranial Hypertension. (bvsalud.org)
Medically refractory idiopathic intracranial hypertension (IIH) is frequently treated with venous sinus stenosis stenting with high success rates. (bvsalud.org)

We will also correlate stenosis severity with longitudinal renal function and determine the value of stenting from the perspectives of quality of life and cost-effectiveness. (umn.edu)
Depending on the severity, doctors will use a combination of endoscopic techniques, surgical repair, tracheostomy, or deployment of stents to hold the airway open and enable breathing. (medicaldialogues.in)
From this point, the extent and the severity of the stenosis is assessed and stent parameters are obtained automatically. (uantwerpen.be)

Asymptomatic Carotid Stenosis: Medical Management or Revascularization? (jwatch.org)

Pediatric laryngotracheal stenosis (LTS), a narrowing of the airway in children, is a complex medical condition. (medicaldialogues.in)

These patients had carotid stenosis greater than 70% in the absence of symptoms. (medscape.com)
Whether renal artery stenting can improve symptoms in patients with heart failure over the long term is unknown. (renalandurologynews.com)
Recovery after carotid artery stenting depends not only on the presence of complications during the procedure, but also on the presence of symptoms at the time of arrival to the hospital. (wikipedia.org)
If cervical stenosis causes symptoms or uterine abnormalities (eg, hematometra, pyometra), cervical cytology and endometrial biopsy or dilation and curettage (D & C) should be done to exclude cancer. (msdmanuals.com)
If symptoms or uterine abnormalities (eg, hematometra, pyometra) are present, exclude cancer by cervical cytology and endometrial biopsy or D & C, then dilate the cervix and place a stent. (msdmanuals.com)

27 patients (diabetes mellitus in 8 cases) were subjected to stenting of the stenotic renal artery while 19 patients (diabetes mellitus in 9 cases) were kept on medical treatment only. (biomedcentral.com)
In this study, the deployment of interwoven stent in a stenotic artery was evaluated through finite element analysis. (asme.org)

Stenting of RAS due to atherosclerosis is followed by stabilization or improvement of Ccr, mainly at the stented kidney, while contralateral renal function showed a decrease. (biomedcentral.com)

Similar evidence of new ischemia in the brain following carotid artery stenting in symptomatic patients is being picked up by investigators in other parts of the world," Dr. Moll stated. (medscape.com)

Patients with IH with low venous pressure gradient venous sinus stenosis seem to benefit equally from venous stenting compared with their higher gradient counterparts. (bvsalud.org)

Two symptomatic subarachnoid hemorrhages in the severe stenosis group versus none in the moderate group (HR 50.91, P=0.504). (patientcareonline.com)

Laryngeal and tracheal stents are solid or hollow absorbable or nonabsorbable tubes of various shapes, sizes, and materials. (medscape.com)
An image depicting laryngeal and tracheal stents can be seen below. (medscape.com)

The trans-femoral route is the traditional approach to carotid stenting. (wikipedia.org)
Are All Carotid Stenting Systems Equal? (jwatch.org)
Carotid Stenting: How Steep the Learning Curve? (jwatch.org)
In an observational study involving Medicare patients undergoing carotid stenting between 2005 and 2007, Dr. Brahmajee Nallamothu and colleagues showed that low annual operator volume and early experience are associated with increased 30-day mortality. (jwatch.org)
Nallamothu and colleagues have performed an observational analysis of Medicare data on fee-for-service beneficiaries undergoing carotid stenting between 2005 and 2007 in 306 hospital referral regions (HRRs). (jwatch.org)
Carotid stenting should not be performed in patients age 70 years or older, according to the results of a new meta-analysis appearing in the Lancet. (jwatch.org)

All the patients had a unilateral stenosis. (biomedcentral.com)
In unilateral stenosis, progression of disease may be survivable with loss of single-lung perfusion. (nih.gov)
