From: Superselective intra-arterial umbilical cord blood administration to BM in experimental animals
Angiography of the arterial system of the hip and thigh in the rabbit and of the femoral nutrient artery (FNA). (a) 3D rotational angiography during iodine contrast injection into the external iliac artery in the rabbit. The FNA (arrow) is seen branching from the femoral artery (FA) and entering the femur. (b) Digital subtraction angiography (DSA) showing a transaxial view of the rabbit femur with iodine contrast-media injection into the FNA opacifying the vascular system of the femoral BM. The FNA is seen traversing the cortical bone and entering the marrow cavity. (c) DSA showing a sagittal view of the rabbit femur with iodine contrast-media injection in the FNA. The arterial BM vascular system along its axis is visualized. The small arrows in (b) and (c) indicate the microcatheter tip position during contrast injection. The same catheter position was used for the superselective i.a. cell injections.
