![]() The tissue between the skin puncture site and the intended arterial puncture site was dissected using an artery clip under ultrasound guidance along the intended needle route toward the anterior wall of the artery. An adequate size skin incision (∼8 mm) was made to accommodate the larger sheath required for EVAR. ![]() Only one groin in our small series was excluded from percutaneous access, and this groin was scheduled and planned for open surgery with cutdown and femoral endarterectomy because of severe stenosis of the CFA.Įvery CFA was punctured using ultrasound guidance with the needle at a 45° angle. In addition, patients who had undergone previous groin open vascular surgery were not included in the present initial series, although we have subsequently performed this technique successfully for such patients requiring repeat groin surgery. Patients with CFAs with severe calcification in their anterior wall without any gap and those with CFAs with significant stenosis were excluded. The CFAs were required to be >7 mm in diameter with no significant stenosis and to have at least an ∼1-cm segment of the anterior wall without calcification for consideration of the pEVAR technique. All the patients scheduled to undergo EVAR who had had common femoral arteries (CFAs) considered suitable for the use of a percutaneous technique were considered for the two techniques.
