Abstract
- Background: This study aimed to clarify the factors for efficient procedures (EP) in superficial femoral artery (SFA) chronic total occlusion (CTO).<br />Methods: We retrospectively analyzed 200 consecutive limbs that underwent treatment for SFA CTO. The patients were divided into three groups according to the main strategies: subintimal angioplasty (SIA) (n = 123), Crosser use (n = 50), and 0.014″ CTO guidewire (CTO-GW) (n = 27). To determine the factors for an EP (EP; contrast volume <130 mL and procedure time <20 min; derived from non-CTO [control] procedures), the variables (P < 0.2) underwent multivariate analysis.<br />Results: SIA included more Trans-Atlantic Inter-Society Consensus C/D lesions and contralateral femoral approaches, and additional GW use (P < 0.05). CTO-GW presented a shorter occlusion length and elapsed time, and used less retrograde approach than the other strategies (P < 0.05). Crossers had a higher incidence of perforation (P = 0.002). The prompt retrograde approach had a similar actual retrograde procedure time, but a shorter total procedure time, compared to that of the delayed adoption (P < 0.001). EP was achieved in 14 limbs (7.0%). Multivariate analysis revealed that occlusion length (adjusted odds ratio [OR], 0.89; 95% CI, 0.81-0.96; P = 0.004) and SIA (OR, 8.71; 95% CI, 1.32-175.27; P = 0.02) were associated with EP.<br />Conclusions: SIA contributed to EP. The timing of the retrograde approach was crucial because its delay resulted in an excessive procedure time.<br />Competing Interests: Declaration of competing interest None.<br /> (Copyright © 2021 Elsevier Inc.
