Tunneled Ipsilateral Sheath: A Novel Technique in Endovascular Management of Superficial Femoral Artery Ostial Lesions.

Ostial lesions of the superficial femoral artery preclude the use of ipsilateral common femoral artery antegrade approach. Access via either the contralateral common femoral or the brachial arteries are the 2 alternative classical approaches. Conversely, using an ipsilateral antegrade approach, through a partially inserted sheath, usually leaves the sheath insecure and frequently hits ostial lesion itself during insertion. Dislodgment from the artery frequently occurs, resulting in loss of access. We describe a technique whereby we insert 2 to 3 cm of the sheath into the common femoral artery and the remaining part of the sheath resides in a fashioned subcutaneous tunnel of the lowermost abdomen. Technical details are provided as well as the results of using this technique on 37 patients. The technique is safe, easy to perform, and reproducible.
