Abdominal X ray during advancement of a guiding catheter and a guiding sheath. (A) The tip of a 4-F catheter (arrow) and a 6-F diagnostic catheter (arrowhead) have passed the stenotic right proximal hepatic artery, while a 7-F guiding sheath is placed in the celiac artery. (B) After advancement of the guiding sheath (curved arrow) beyond the stenotic proximal part of the right hepatic artery, straightening of the tortuous hepatic artery is demonstrated. (C) Angiography from the guiding sheath demonstrates dissection of the right hepatic artery. Contrast medium (arrows) is pooled in the false lumen.
