A 20-year experience with portal and superior mesenteric venous injuries: has anything changed?
Despite improvements in trauma care, mortality of PV and SMV injuries remains high. Shock, active hemorrhage, and associated injuries were predictive of increased mortality.
The data support the differential association of two well-defined clinical forms of AA, namely long-standing AT/AU and long-standing patchy AA, with specific HLA antigens and age at onset; they also suggest that the broad antigen HLA-DQ3, DQB1*03, is a likely candidate for general susceptibility to AA. Our findings also suggest a bimodal pattern of disease with an early-onset form associated with greater severity, long duration, and family history of the disease and a late-onset form characterized by milder severity, shorter duration, and low family incidence.
