CT findings of mesenteric injury after blunt trauma: implications for surgical intervention.
The purposes of this study were to determine the spectrum of CT findings of mesenteric injury, to compare CT findings of mesenteric injury with surgical observations, and to assess the potential of CT to predict which patients with mesenteric injury require laparotomy. ⋯ The CT finding of mesenteric bleeding or bowel wall thickening associated with mesenteric hematoma or infiltration in the blunt trauma patient indicates a high likelihood of a mesenteric or bowel injury requiring surgery. The finding of focal mesenteric hematoma or infiltration without adjacent bowel wall thickening is nonspecific and can occur both in mesenteric or bowel lesions that require surgery and those that do not.

Treatment of renal angioplasty failure by percutaneous renal artery stenting with Palmaz stents: midterm technical and clinical results.
Renal artery stenting has recently been used to treat failures or complications of renal angioplasty. Although technical results and complication rates have been reported, clinical follow-up and long-term data are limited. The purpose of this study was to evaluate the midterm clinical efficacy and safety of Palmaz stents in rescuing renal artery angioplasty failures. ⋯ Midterm results of renal artery stenting with the Palmaz stent to treat immediate or late angioplasty failures reveal improvements in blood pressure and renal function similar to those of successful primary balloon angioplasty.

Predicting clinical outcome of nonsurgical management of blunt splenic injury: using CT to reveal abnormalities of splenic vasculature.
Using CT to grade blunt splenic injuries frequently does not predict clinical outcome. This retrospective, blinded study evaluated whether revealing a traumatic pseudoaneurysm or frank hemorrhage on an initial CT examination can be used to predict the successful clinical outcome of patients managed without surgery. ⋯ The failure rate in patients with nonsurgically managed blunt splenic injuries may be markedly reduced if patients with traumatic pseudoaneurysm or active hemorrhage revealed on emergent CT are treated with early surgical or endovascular repair.
