Dr. Katherine MacCallum First in Rhode Island to Perform Limb-Saving Limflow® TADV Procedure
Breakthrough procedure reduces amputation risk for patients with Chronic Limb-Threatening Ischemia
We’re not only saving legs–we’re enabling these patients to retain their independence, lessen the need for prolonged hospital and rehabilitation stays, and ultimately saving lives.”
PROVIDENCE, RI, UNITED STATES, June 25, 2025 /EINPresswire.com/ -- In a major advancement for patients suffering from advanced peripheral arterial disease (PAD), Katherine P. MacCallum, M.D., vascular surgeon with Brown Surgical Associates and Brown University Health, has become the first physician in Rhode Island to perform the LimFlow® TADV (Transcatheter Arterialization of the Deep Veins) procedure — a breakthrough treatment for patients with Chronic Limb-Threatening Ischemia (CLTI) who face the imminent threat of major amputation.— Dr. Katherine P. MacCallum, Vascular Surgeon
CLTI is a severe and life-altering form of PAD that manifests as non-healing wounds, intractable pain, and eventual limb loss1. The LimFlow® TADV System is the first and only FDA-approved device designed to provide a minimally invasive solution by rerouting oxygenated blood into the deep venous system, restoring circulation where arteries have failed.
“This technology allows us to offer new hope to patients who previously had no other treatment options besides major amputation,” said Dr. MacCallum. “By restoring blood flow to the foot, we’re not only saving legs–we’re enabling these patients to retain their independence, lessen the need for prolonged hospital and rehabilitation stays, and ultimately saving lives.”
A Game-Changer for High-Risk Patients
The LimFlow® procedure has been shown to significantly improve outcomes for patients with CTLI and no options for surgical bypass:
● 73% limb salvage at 12 months; 68% sustained at 24 months
● 92% healed or healing wounds at 12 months; 83% at 24 months
● 69% of patients pain-free at 24 months²
“LimFlow® TADV provides a new option for treating no-option CLTI with demonstrated limb salvage and wound healing through two years, even in the sickest patients,” said Dr. Dan Clair, as presented at VIVA 20243.
Multidisciplinary Excellence
The success of the LimFlow® procedure requires a collaborative team approach involving vascular surgeons, vascular lab technologists, wound care specialists, and podiatrists. Brown Surgical Associates and Brown University Health have long been at the forefront of such multidisciplinary models, and this new offering continues their tradition of innovation and comprehensive patient care.
Expanding Access to Lifesaving Care
By performing the first LimFlow® TADV procedure in Rhode Island, Dr. MacCallum and her team are paving the way for broader access to this cutting-edge technology, ensuring patients throughout the region have a chance at limb salvage, improved function, and a better quality of life.
