Figure 1 : A : overview of the retroperitoneal space after removing the GI tract . The 7cm juxtarenal AAA is in the center , the inferior vena cava is held up with the forceps . The red markers on the anterior surface of the abdominal aorta represent the origins of ( top-down ) the celiac trunk , superior mesenteric artery and inferior mesenteric arteries . Notice the left sided retroperitoneal hematoma ( in black ) and the bilateral accessory renal arteries . B : schematic measurement of the studied Abdominal Aortic Aneurysm .
Figure 2 : Close up on the proximal neck . The red arrows point to the right and left renal arteries . Notice the very short proximal neck ( 5mm ) of this juxtarenal AAA . The two kidneys are held up by hand . The red markers are placed in the origin of the celiac trunk ( up ) and the superior mesenteric artery ( below ). The left renal artery was cut and reflected upward to show the proximal neck of the aneurysm .
