Abstract

Background: Subintimal angioplasty is a common treatment for chronic total occlusions (CTOs) in the iliac and infrainguinal arteries. Although technical success has been described using intravascular ultrasound-guided reentry devices (IVUS-RED), outcomes are still not well defined. This report describes the technical aspects and longitudinal follow-up after intravascular ultrasound-guided reentry of iliac and infrainguinal CTOs. Methods: A retrospective review was performed of 20 patients with lower extremity CTO treated with IVUS-RED from 2011 to 2013. A matched cohort of patients who underwent lower extremity interventions without the use of IVUS-RED was also identified. Procedural success, patency estimates, ankle-brachial indices (ABIs), complications, and limb salvage were analyzed. Results: Twenty patients (mean age, 69 ± 13 years), including 11 men and 9 women, underwent attempted IVUS-REDeguided recanalization. Median follow-up was 4.3 months (range, 0.4-24). Eleven patients presented with critical limb ischemia (CLI), and 9 presented with claudication. Technical success was achieved in 18 (90%) patients. Ten common iliac arteries, 3 external iliac arteries, and 5 superficial femoral arteries (SFA) were treated. No intraoperative complications resulted from device use. After procedure, ABIs significantly increased (0.5-0.9; P < 0.01) in the 13 patients with follow-up. Primary patency for the entire cohort was 62% at 12 months. No patient treated for claudication required reintervention, whereas 3 (27%) of those treated for CLI required repeat interventions. During follow-up, 2 patients died unrelated to the procedure, 1 patient required an amputation, and 1 patient eventually required open revascularization. When the IVUS-RED group was compared with a cohort matched on Trans-Atlantic Inter-Society Consensus and age, no difference was found in runoff scores and patency between the 2 groups during follow-up (P > 0.05). Conclusions: Recanalization of CTO using IVUS-RED is safe and effective. Use of IVUS-RED does not adversely impact outcomes in conjunction with other endovascular techniques. Early follow-up demonstrates acceptable patency, especially in patients with claudication, and freedom from reintervention.
