A novel technique to reach the contralateral iliac artery in Leriche syndrome.

Abstract

The endovascular approach is the first choice of treatment in high-risk patients suffering from Leriche syndrome. Although many techniques and devices have been developed, there are still difficulties in accessing the true lumen. Herein, we reported a novel technique to increase the support and ease of crossing the lesion. We presented a case report of a 45-year-old male patient with Leriche syndrome. The patient refused surgery; therefore, he was scheduled for endovascular treatment. We attempted to cross the right and left common iliac occlusions by intraluminal crossing. The left common iliac artery couldn't be cannulated despite the stiff wires and percutaneous intentional extraluminal revascularization (PIER). Afterward, a cross-over approach was performed from the right side to reach the ostium of the left common iliac artery. To increase the support, a non-absorbable suture was stitched up to the tip of the guiding catheter and kept slightly taut like a lasso. Finally, successful penetration was achieved with the novel assistive technique. Endovascular treatment for Leriche syndrome is a precious alternative to open surgery. Intraluminal crossing, PIER, and re-entry devices are the most preferred techniques. Increasing the technical success of intraluminal crossing and PIER leads to an apparent reduction in cost.
