van der Veen D, Holewijn S, Bellosta R, et al. - Development of the Gore Excluder Iliac Branch Endoprosthesis (IBE) was done to preserve perfusion in the hypogastric artery after endovascular repair of aorto-iliac aneurysms. Researchers conducted a physician initiated international multicenter, prospective cohort study with the aim to report the 12 month technical and clinical outcomes of treatment with this device. Of 100 enrolled patients, 97% were male, with a median age of 70.0 years; 42.7% of the patients had an abdominal aortic aneurysm (AAA) above threshold for treatment and the remaining patients had the iliac artery diameter as the indication for treatment. Outcomes suggest that for the treatment of aorto-iliac aneurysms, use of the Gore Excluder IBE exhibits a satisfactory primary patency through 12 months, with significant reduction of diameters, a low re-intervention rate, and favorable clinical outcomes.
