Details of the Parallel Guidewire Anchoring Technique. Angioplasty without stenting of the graft hepatic artery in a 70-year-old patient. A. Initial arteriography showed a graft hepatic artery stenosis (arrowhead). B. Catheterization was performed as distally as possible in the splenic artery with a catheter and a microcatheter (large arrow) through a long sheath (curved arrow). C. A stiff 0.014” guidewire (thin arrow) was introduced into the microcatheter (large arrow). D. The microcatheter and the catheter were completely removed. E. The catheter and the microcatheter (large arrow) were introduced in parallel of the stiff guidewire and used to catheterize the common hepatic artery. F. The stiff guidewire (thin arrow) was removed from the splenic artery to position the long sheath further into the graft hepatic artery.
