  • stent
  • A less-invasive option, called carotid stenting, involves inserting a catheter into an artery in the groin, advancing it to the carotid artery, opening the blockage with a balloon, and leaving behind a wire cage (or stent) to hold the artery open. (harvard.edu)
  • This distinction corresponds to the design and results of previous clinical trials on surgical versus medical treatment of carotid stenosis for stroke prevention as well as of current studies comparing surgical with interventional procedures (angioplasty with or without stent) [ 3 - 8 ]. (hindawi.com)
  • Instead a fine wire is inserted into an artery in the leg and passed up into the carotid artery, and the stent is then moved into place along the wire. (nice.org.uk)
  • plaque
  • Only within a small time window, when carotid stenosis shows progression and high plaque vulnerability, either in the presence of or without clinical signs or symptoms, there is a higher incidence of stroke. (hindawi.com)
  • Measurement of peak systolic velocities (PSVs) in ICA has been used worldwide, and maximal PSV, defined between 1.25-1.4 m/s, was used delimitate stenosis to maximum 50%, sometimes with mandatory plaque or intimal thickening visible [ 7 ]. (hindawi.com)
  • Also called carotid artery disease, carotid stenosis is caused by a buildup of plaque inside the artery wall that reduces blood flow to the brain. (iowaclinic.com)
  • To determine baseline clinical and ultrasonographic plaque factors predictive of progression or regression of asymptomatic carotid stenosis and the predictive value of changes in stenosis severity on risk of first ipsilateral cerebral or retinal ischemic events (including stroke). (nih.gov)
  • Younger age, high grades of stenosis, absence of discrete white areas in the plaque, and taking lipid lowering therapy were independent baseline predictors of increased incidence of regression. (nih.gov)
  • High serum creatinine, male gender, not taking lipid lowering therapy, low grades of stenosis, and increased plaque area were independent baseline predictors of progression. (nih.gov)
  • Plaque often builds up at that division, and causes a narrowing (stenosis). (ebi.ac.uk)
  • Plaque can also build up at the origin of the carotid artery at the aorta. (ebi.ac.uk)

  • cerebral ischemia
  • In elderly with cerebral ischemia, larger diameters of common carotid artery and lower PSV have been observed, probably due to increased intracerebral circulatory resistance [ 10 , 11 ]. (hindawi.com)
  • methods
  • Agreement between 3.0 T and other methods results poor, and this could be due to the fact that the 3.0 T has a better resolution compared to a US and MR 1.5 T. These methods seem to have similar efficacies for the evaluation of vessel stenosis, legitimizing the use of the developed phantom as a versatile and reproducible instrument that could be used during quality controls programs.

  • surgical
  • Due to the authors' extensive experience in re-operative management of the carotid disease, the intricacies and step-by-step surgical approach are described, including pitfalls and complications. (springer.com)
  • indications
  • IG-A and IG-B account for more than 90% of all extracranial carotid procedures and consist of indications supported by high-level evidence and recommended in numerous guidelines ( 1 3 ). (aerzteblatt.de)
