I'm trying to understand the reasons for increased hemorrhage risk after abdominal surgery. Specifically the statement "Blood pools in the pelvic area after abdominal surgery and increases the risk for hemorrhage".
1) I understand blood pooling in the areas where vessels are damaged, but not why it pools in an area other than the damage. While some veins that would return the blood to the heart have been damaged, there are others that can pick up the extra load.
2) Aside from the severed vessels is the increased risk related to pressure of pooling blood? or nearby location if there is a rupture?
