A retrospective analysis of 64 patients treated between 2022 and 2025 using a novel mechanical thrombectomy system to treat dialysis access thrombus showed function was restored in 91% of those treated.
Data from the study of the InThrill system (Stryker/ Inari Medcial) were presented by Nicole Ilonzo, MD, a vascular surgeon at NewYork-Presbyterian in Brooklyn, New York, at EVS 2025. AV fistulas and grafts
The study included patients with arteriovenous (AV) fistulas and grafts, with 31% of those treated having fistulas. “Clinical success, defined as restoration of access function for dialysis, was achieved in 91% of patients,” Ilonzo told the 2025 edition of the Eastern Vascular Society (EVS) annual meeting in Nashville, Tennessee (Sept 4–7).
“Primary patency at one month was 72%, higher than 40-60% range reported in studies using only balloon maturation techniques.”
Device-related complications were minimal, she said, with 3% experiencing trauma at the access site and another 3% having distal embolization. All were resolved intraprocedurally, Ilonzo added. “Importantly, there were no deaths, vessel perforations or major adverse events.”
The InThrill thrombectomy system “shows promise and is a safe and effective alternative to traditional AV access thrombectomy techniques,” she concluded
