ABSTRACT

BACKGROUND: Improved equipment and techniques have resulted in transition from surgical bypass to endovascular intervention to treat superficial femoral artery (SFA) chronic total occlusions (CTO). A change in access site to radial (TRA) or tibiopedal (TPA) artery for the treatment of these SFA CTO has been reported. The feasibility, efficacy and safety of these two access sites for treatment of SFA CTO have not been reported. METHODS: We performed an as treated analysis of 184 SFA CTO interventions in 161 patients from 01/2014 to 09/2016 using either primary TRA or TPA (operator discretion) at two institutions. Primary end point was 30 day major adverse event (MAE) - death, amputation or target vessel revascularization, secondary endpoint was success of procedure. RESULTS: Primary TRA was used in 46 patients with 47 CTO lesions .Primary TPA was used in 115 patients with 137 CTO lesions. Primary crossing success rate was higher with TRA compared to TPA (74% vs 54%, P = 0.01). Dual TRA-TPA was required in 72 prior uncrossed lesions resulting in a crossing and procedural success of 99% and 96% respectively. The overall crossing and procedural success rate using either of these approaches was 99% and 98% respectively. The 30 day MAE was 5% in TRA arm, 0% in TPA arm and 2% in dual TRA-TPA arm, P = 0.08. All access sites were patent, confirmed by ultrasound. CONCLUSION: The treatment of SFA CTO is feasible and safe using both TRA or TPA approach providing high success rates and no access site complications.

ABSTRACT

OBJECTIVES: The purpose of this prospective study was to evaluate the acute success and complication rates of combined transradial and transpedal access for femoral artery intervention. BACKGROUND: Improved equipment and techniques have resulted in transition from transfemoral to transradial access for intervention of superficial femoral artery. METHODS: Between 2014 and 2016, clinical and angiographic data from 145 consecutive patients with symptomatic superficial femoral stenosis, treated via primary radial access using the 6-F SheathLess Eaucath PV guiding catheter were evaluated in a pilot study. Secondary access was achieved through the pedal or popliteal artery. The primary endpoints were major adverse events, target lesion revascularization, and rates of major and minor access-site complications. Secondary endpoints included angiographic outcome, procedural factors, crossover rate to femoral access site, and duration of hospitalization. RESULTS: Technical success was achieved in 138 patients (95.2%). Combined radial and pedal access was obtained in 22 patients (15.1%). The crossover rate to a femoral access site was 2%. Stent implantation was necessary in 23.4% of patients. Chronic total occlusion recanalization was performed in 63 patients, with a 90.4% technical success rate. The mean contrast consumption, radiation dose, and procedure time were 112.9 ml (101.8 to 123.9 ml), 21.84 Gy/cm2 (9.95 to 33.72 Gy/cm2), and 34.9 min (31.02 to 38.77 min), respectively. The cumulative rate of access-site complications was 4.8% (0% major, 4.8% minor). The cumulative incidence rates of major adverse events at 3 and 12 months follow-up was 8.3% and 19.2%. The cumulative incidence rates of death at 3- and 12-month follow-up were 2.8% and 5.6%. CONCLUSIONS: Femoral artery intervention can be safely and effectively performed using radial and pedal access with acceptable morbidity and a high technical success rate.
