The cohort included 13 males and 5 females, with a mean age of 70.4\u2009\u00b1\u20097.2 years. After retrograde femoral access, contralateral interventions were performed using the LS\u2010ACT protocol.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The LS\u2010ACT was performed in all 18 patients, achieving successful transition from femoral retrograde to antegrade access. Seven of these patients underwent simultaneous bilateral lower extremity arterial interventions. In 11 patients, the LS\u2010ACT was utilized following failed antegrade puncture due to obesity, scarred puncture sites, or a high bifurcation of the profunda femoris artery. Notably, 8 patients presented with hemodynamically significant improvement of ipsilateral iliac artery stenosis, including 2 who had undergone prior stenting. No LS\u2010ACT relevant complications occurred.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The LS\u2010ACT demonstrates substantial clinical utility in real\u2010world practice.
