ABSTRACT

A percutaneous medial saphenous artery catheterization technique for swine femoral access is described. The medial saphenous artery is accessed with a 22-gauge catheter-over-needle assembly, followed by 4-Fr 10-cm sheath insertion using the Seldinger technique. The 4-Fr sheath is subsequently exchanged over a 0.035-inch guidewire for a 5-Fr sheath to establish central artery access. The technique was applied to seven vessels in five swine, with successful catheterization in five vessels. The reason for failure was technical difficulty in one case and vasospasm in the other. Central artery access was still possible through direct exposure and puncture of the medial saphenous artery or the femoral artery. This technique may provide an alternative option for central artery access in swine. However, improvement in more reliable catheterization is warranted.
