Figure 3 Schematic diagram of the hypothesized mechanism of dynamic redistribution of lymphatic leakage(A) During the first lymphatic embolization on postoperative day (POD) 94, retrograde chylous flow through the lumbar lymphatics may have contributed to persistent leakage from the internal iliac region (red droplets), despite ongoing embolization. (B) After surgical ligation of the internal iliac leak (POD 102), lymphatic flow may have been redirected through a collateral pathway (orange dashed arrow), resulting in a new leak in the external iliac region (green ellipse and droplets). Repeat embolization of this secondary leak site achieved definitive resolution. These schematics represent the authors’ proposed explanation for the observed sequential change in leak site and do not depict a definitively proven anatomical sequence.
