Radiologists and engineers develop a modified catheter to reduce contrast material injuries
Though rare, IV contrast material administration can sometimes result in patient injury. However researchers have developed a modified catheter that may prevent such events from occurring. view more (2009-09-21)
Massive necrosis after trans-catheter treatment is more common in the presence of tumor capsule
Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Prognosis of patients with HCC complicating cirrhosis mainly depends on the tumor growth, progression of the underlying liver disease and the effectiveness of antitumoral treatment. view more (2007-11-26)
An Antimicrobial Solution For Blocked Urinary Catheters? (p 1435)
Authors of a research letter in this week's issue of THE LANCET propose a new method for inflating urinary catheters-which could avoid common problems of encrustration and blockage of the catheter. Urinary catheters are usually inflated with water, but this often results in bacterial build-up leading to catheter encrustration and blockage. David... view more... (2003-04-23)
Catheter angiography may be an unnecessary follow-up to CT angiography
Even in challenging cases, CT angiography (CTA) offers an accurate and rapid diagnosis for blunt trauma victims who may have aortic or great vessel injury negating the need for more invasive procedures. view more (2007-09-21)
Disposable catheter breakthrough, a world first
A unique low cost disposable solid-state catheter that can measure swallowing pressure has been developed by a University of South Australia research team using intelligent manufacturing processes that eliminate the infection risks posed by existing catheters. view more (2006-02-06)
Breast cancer treatment procedure gives women more options
A new minimally invasive approach to partial breast irradiation provides another treatment option for women with breast cancer. The researchers presented their findings today at the annual meeting of the Radiological Society of North America. view more (2006-11-30)
Low-risk balloon trip to the heart
Patients who are at high-risk of having a heart attack or who require a bypass must undergo a coronary angiography. A new balloon catheter, being presented at the MEDTEC exhibition, allows this to be done more swiftly, more easily and with less risk than previous examinations. Calcium and cholesterol can block coronary blood vessels. The thicker... view more... (2002-03-05)
Use of pulmonary artery catheter decreases substantially in US
Use of the pulmonary artery catheter decreased by 65 percent in the U.S. between 1993 and 2004, possibly due to growing evidence that this invasive procedure does not reduce the risk of death for hospitalized patients. view more (2007-07-25)
The benefits of reperfusion therapy
The wider use of reperfusion therapy in patients with heart attack (AMI) can save millions of lives in Europe. view more (2009-09-01)
MDCT eliminates need for catheter angiography for aortic injury diagnosis, saving time and lives
Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers. view more (2007-05-07)
Safer ICUs: Cheap, simple, 'low-tech' steps work
Hospitals will quickly slash the rate of common, costly and potentially lethal catheter-related bloodstream infections in their intensive care units (ICUs) by using cheap, low-tech, common-sense measures like hand washing, timely removal of unneeded catheters, and use of sites other than the groin to place lines when possible. view more (2006-12-28)
One fourth of older patients receive catheters for no reason
A study of 1,586 hospitalized patients age 70 and older at two Ohio hospitals indicates that 24 percent were given medically unnecessary urinary catheters. view more (2006-05-23)
Potential for noninvasive brain tumor treatment
Duke University engineers have taken a first step toward a minimally invasive treatment of brain tumors by combining chemotherapy with heat administered from the end of a catheter. view more (2009-06-17)
ORNL advances therapy for Parkinson's, other diseases
By miniaturizing a device that monitors the delivery of healthy cells, researchers at Department of Energy's Oak Ridge National Laboratory are developing a powerful instrument for physicians to use in treating patients with Parkinson's syndrome, brain tumors and other diseases. view more (2009-07-23)
Preventing Sudden Death: EBCT Scans Trump Angiography at Detecting Killer Heart Defect
Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death. view more (2005-10-11)
Magnetically guided catheter zaps atrial fibrillation
A remotely-controlled catheter device guided by magnetic fields provides a safe and practical method for delivering radio frequency ablation treatment in the hearts of patients with atrial fibrillation. view more (2006-03-31)
Late-breaking results of clinical trial on therapeutic endovascular cooling reported at TCT 2008
Late-breaking results from the COOL RCN (COOLing to Prevent Radio Contrast Nephropathy in Patients Undergoing Diagnostic or Interventional Catheterization) Trial were presented during the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF). view more (2008-10-15)
When seconds count: Interventional radiology treatment for pulmonary embolism saves lives
Catheter-directed therapy or catheter-directed thrombolysis-an interventional radiology treatment that uses targeted image-guided drug delivery with specially designed catheters to dissolve dangerous blood clots in the lungs-saves lives and should be considered a first-line treatment option for massive pulmonary embolism, note researchers in the... view more...

Heart catheters do not benefit patients
Doctors should probably stop using pulmonary artery catheters because they do not benefit patients, say doctors from Australia in this week's BMJ. view more (2006-11-03)
Heating heart with catheter better than drugs for common heart rhythm disorder
Treating a common heart rhythm disorder by burning heart tissue with a catheter works dramatically better than drug treatments, a major international study has found. view more (2009-05-15)
