Via the left femoral arterial sheath, an 8 Fr Amplatz guide
catheter was placed into the proximal descending aorta and two Lunderquist (Cook Medical, Bloomington, Indiana) wires were sequentially placed into the aortic arch through this catheter.
A super stiff Amplatz guide
wire (Boston Scientific; Boston, MA) was introduced through the needle and coiled in the gastric fundus.
A 140 cm, unmarked, polytetrafluoroethylene coated, 0.35 mm diameter Amplatz guide
wire was then passed through the injection port of the FOS and advanced through the working channel until it could be visualised within the trachea beyond the tip of the scope.
A 5-Fr SOS OMNI Selective Catheter (Angio-Dynamics, Queensbury, NY) was then advanced more distally over an Amplatz guide
wire into the left gastric artery.
