When failure due to bleeding is dichotomized as before
or after 48 hours (early vs. late), there is a low but
disturbing incidence of late bleeds (2-4%) presumably
due to delayed rupture of splenic artery
pseudoanuerysms.26,43,44
These late bleeds tend to occur at 4 days to 8 days, but
some occur weeks later. The practice of obtaining
follow-up CT scans is also quite variable. The
University of Tennessee Memphis group has championed the
concept of obtaining CT scans before early hospital
discharge of patients with high grade splenic injuries.
However, their most recent series demonstrates that
roughly a quarter of pseudoanuerysms occurred in grade 1
and 2 injuries and over half occurred in grade 3
injuries. This is another issue that requires
prospective study before definitive recommendations can
be made. In general, follow-up CT scans as out patients
are not helpful but may be used selectively to confirm
healing in patients who are asking to be released to
pursue high risk behavior (such a bull riding or
football).
