Medical Procedure at ROPH Brings to Light New Treatment for Peripheral Artery Disease (PAD)

(Oak Park) -- Rush Oak Park Hospital is the first hospital in the surrounding area to acquire and use a newly approved technology that allows vascular surgeons to see in real-time the plaque they are removing during an atherectomy, a minimally invasive procedure that helps treat peripheral artery disease (PAD).  “The fact that a physician is visually guided while removing the buildup of plaque in the blood vessel can help prevent the formation of scar tissue, which can possibly lead to another blockage down the road,” says Charles Schubert, MD, the first vascular surgeon to use the Pantheris Lumivascular Atherectomy System at ROPH.

Testing Non-Breast/Ovarian Cancer Genes in High-Risk Women Leaves More Questions Than Answers

Running large, multi-gene sequencing panels to assess cancer risk is a growing trend in medicine as the price of the technology declines and more precise approaches to cancer care gain steam.
