Use of images seemed not to affect this risk. Regarding complicated AA, age, the length of the symptoms and observation affected independently the risk (p \ 0.05). Images use didn't modify this risk.  ...  Conclusions: We found a non-protocolized increase in the use of images which was not associated with the risk either of negative appendectomy nor complicated AA Conclusions: EVAR treatment of ruptured  ...  Comments: Planning of surgical strategy is essential to retrieve by VATS intra-pulmonary foreign bodies; CT images and their 2/3D reconstructions are useful to identify active or potential vascular or  ...
