Combined Transradial and Transpedal Approach for Femoral Artery Interventions
Bibliographic record
Abstract
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. Improved equipment and techniques have resulted in transition from transfemoral to transradial access for intervention of superficial femoral artery. 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. 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%. Femoral artery intervention can be safely and effectively performed using radial and pedal access with acceptable morbidity and a high technical success rate.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
