Renal artery interventions could damage kidneys
A Wake Forest University study has confirmed that plaque fragments released during renal artery revascularization could impair kidney function. Findings suggest physicians may need to rethink how to perform these procedures safely.
A Wake Forest University study has confirmed that plaque fragments released during renal artery revascularization could impair kidney function. Findings suggest physicians may need to rethink how to perform these procedures safely.
Dr. Matthew Edwards and colleagues assessed 28 patients who underwent renal artery angioplasty and stenting between July 2005 and December 2006. The investigators used a protective device to keep plaque fragments from passing through the vessel. Blood samples taken from the occluded area carried embolic particles large enough to disrupt renal function (J Vasc Surg 2007;46[1]:55-61).
Findings showed a statistically significant association between stent size and the release of potentially hazardous particles. Aspirin, on the other hand, helped reduce debris counts. Researchers could not establish the true role protective devices play in this setting.
FDA Clears Virtually Helium-Free 1.5T MRI System from Siemens Healthineers
June 26th 2025Offering a cost- and resource-saving DryCool magnet technology, the Magnetom Flow.Ace MRI system reportedly requires 0.7 liters of liquid helium for cooling over the lifetime of the device in contrast to over 1,000 liters commonly utilized with conventional MRI platforms.
SNMMI: Botox May Facilitate Relief from Dry Mouth Side Effect of PSMA-Targeted Radiopharmaceuticals
June 25th 2025For patients being treated with radiopharmaceutical agents for metastatic prostate cancer, the combination of botulinum toxin and an anti-nausea patch led to a 30 percent reduction in PSMA uptake in the salivary glands, according to preliminary research findings presented at the SNMMI conference.
