Multicenter Study
Multiinstitutional experience with the management of superior mesenteric artery injuries.
Superior mesenteric artery (SMA) injuries are rare and often lethal injuries incurring very high morbidity and mortality. The purposes of this study are to review a multiinstitutional experience with these injuries; to analyze Fullen's classification based on anatomic zone and ischemia grade for its predictive value; to correlate the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) for abdominal vascular injury with mortality; and to identify independent risk factors predictive of mortality, describing current trends for the management of this injury in America. ⋯ SMA injuries are highly lethal. Fullen's anatomic zones, ischemia grade, and AAST-OIS abdominal vascular injuries correlate well with mortality. Injuries to Fullen's zones I and II, Fullen's maximal ischemia grade, and AAST-OIS injury grades IV and V, high-intraoperative transfusion requirements, and presence of acidosis and disrhythmias are significant predictors of mortality. All of these predictive factors for mortality must be taken into account in the surgical management of these injuries.

Comparative Study
Magnetic resonance imaging and abdominal wall hernias in aortic surgery.
The aim of this study was to evaluate the incidence of abdominal wall hernias (AWH) in patients operated on for abdominal aortic aneurysm (AAA) compared with patients treated for aortoiliac occlusive disease. The efficacy of MRI in early diagnosis of AWH also was studied. ⋯ Ours and other studies recall collagen synthesis disorders to explain the statistical association observed among AAA, inguinal hernias, and AWH. MRI, especially in patients at risk, appears to be an effective diagnostic approach to early detection of AWH.
