IntroductionThe aim of this study was to evaluate the feasibility and safety of ultrasonography-guided antegrade common femoral artery puncture and subsequent superficial femoral artery access without the aid of fluoroscopy. Factors that could affect access time were also assessed.MethodsA total of 294 cases from 218 consecutive patients (163 men, 55 women; mean age: 66.9 ± 12.7 years) who underwent lower extremity endovascular procedures were retrospectively evaluated. The time between the injection of local anesthetic and the insertion of the microsheath into the superficial femoral artery was measured. The common femoral artery diameter, cutis thickness, distance between arterial puncture site and common femoral artery bifurcation, degree of common femoral artery calcification, body mass index, and history of previous access were investigated to assess their relationship with access time. Furthermore, all cases were assessed with ultrasonography for access-site complications before discharge.ResultsTechnical success was achieved in 293 of 294 procedures (99.7%). The mean time for superficial femoral artery access was 1.9 ± 0.8 min (range, 0.7-3.7 min). Additional fluoroscopic guidance was needed in one case. There were moderately positive correlations of body mass index (r = 0.75; p < 0.001) and cutis thickness (r = 0.58; p < 0.001) with access time. The other variables failed to reveal significant correlations with access time. Five groin hematomas occurred after percutaneous transluminal angioplasty. Complications such as pseudoaneurysm, arteriovenous fistula, or retroperitoneal hematoma were not observed.ConclusionAntegrade common femoral artery puncture with subsequent superficial femoral artery access conducted solely under ultrasonography guidance was feasible and safe. In addition, the antegrade access time showed positive correlations with body mass index and cutis thickness.
