Arsenio et al identified risk factors associated with mortality in patients with traumatic injury to the superior mesenteric artery. Injury to the superior mesenteric artery can have severe physiologic consequences and is technically difficult to repair. The study involved 27 institutions throughout the United States.
Risk factors associated increased mortality based on logistic regression analysis:
(1) transfusion > 10 units packed red blood cells
(2) intra-operative acidosis
(3) cardiac dysrhythmias
(4) injury to the main trunk of the superior mesenteric artery proximal to the branching of the middle colic artery (Fullen Zones I or II)
(5) multisystem organ failure
(6) age > 55 years of age
where:
• The items selected for stepwise logistic regression analysis were risk factors with a significance level of p < 0.10 in univariate analysis and having > 90% of data complete.
