Primary Use of the TruePath Crossing Device for Infrainguinal Chronic Total Occlusions With Intravascular Ultrasound Evaluation
2018
Purpose: To evaluate the use of the TruePath crossing device as the primary recanalization tool for infrainguinal chronic total occlusions (CTO). Methods: A retrospective analysis was conducted of 50 patients (mean age 75 years; 26 men) with 55 infrainguinal CTOs treated with the TruePath between March 2017 and September 2017 at a single center. The mean occlusion length was 138±55 mm, and femoropopliteal lesions accounted for 65% of the 55 lesions. The primary outcome measure was CTO crossing using the TruePath alone; secondary outcomes were assisted success (>50% lumen gain using the TruePath), device-related complications, and intraluminal crossing evaluated by intravascular ultrasound (IVUS). Results: Complete success was achieved in 33 (60%) of 55 lesions having a mean occlusion length of 145±72 mm. Among these, the true lumen crossing rate was 97% according to IVUS evaluation. Assisted success was achieved in 15 (68%) of the 22 failures. Complete/assisted success, in which the TruePath was thought t...
