Obesity Increases the Risk of Primary Nonfunction and Early Access Loss, and Decreases Overall Patency in Patients Who Underwent Hemodialysis Reliable Outflow Device Placement

HeRO catheters offer a reliable, and possibly the last, alternative in hemodialysis access-challenged patients. In our population, obesity was a significant risk factor for primary nonfunction, early graft loss, and a shorter overall graft patency. BMI, as a continuous variable, can serve as a predictor of primary nonfunction and early graft loss after adjustment for age, race, sex, and diabetes. Obesity's effect on HeRO catheters has not been amply addressed; therefore further prospective studies are warranted.
