A new treatment has just been cleared by the FDA to provide relief for patients suffering from the painful symptoms of peripheral artery disease, or PAD – a condition caused by a build-up of plaque that reduces blood flow in the arteries of legs or feet.
Tyler Cardiac & Endovascular Center is among the first in the United States to begin treating patients with the new technology. The device, Avinger’s Pantheris lumivascular atherectomy system, is an innovative image-guided therapy that, for the first time ever, allows physicians to see and remove plaque simultaneously during atherectomy – a minimally invasive procedure that involves cutting plaque away from the artery and clearing it out to restore blood flow.
Because the Pantheris device incorporates real-time optical coherence tomography (OCT) imaging on a therapeutic catheter – like having a small camera on the tip of the device – physicians are able to remove this plaque more precisely than ever before, with less risk of damage to the artery walls which can result in aggressive scarring that greatly increases the risk of restenosis, or re-narrowing of the artery. In the past, physicians have had to rely solely on X-ray as well as touch and feel to guide their tools while they try to treat complicated arterial disease.
For patients, this safe and more-precise treatment may potentially reduce the need for follow-up procedures and stents.
Clinical results confirm that the technology is safe and effective: a 130-patient study showed a target lesion revascularization rate of just 8%, and not a single event of vessel perforation, clinically significant dissection or late aneurysm resulted from Pantheris. In addition, this radiation-free technology may help minimize radiation exposure to clinicians and patients by decreasing use of fluoroscopy.
PAD is a common, costly and deadly disease that affects nearly 20 million adults in the U.S. Despite the fact that the condition greatly impacts quality of life – cramping, numbness, discoloration and pain are common symptoms – it remains undertreated.
Dr. Jeffrey Carr is available for interviews to offer insights into PAD, its causes and symptoms, as well as details about this new treatment option for PAD.
In addition, a patient treated with the new system is available to discuss her experience with PAD and the Pantheris System.
