Comparative Study
[Endovascular therapy of abdominal aortic aneurysm: results of a mid-term follow-up].
Prospective study to evaluate clinical results and complications of endovascular abdominal aortic aneurysm treatment in a mid-term follow-up. ⋯ In selected patients, endovascular aneurysm treatment is an effective alternative to open surgery. It is safely performed in local anesthesia with low mortality rate and a low number of acute complications. Intermediate follow-up revealed re-interventions in around one quarer of all patients, especially when Vanguard or Stentor endografts were implanted. Primary coil embolization of all aortic branches prior to endovascular grafting improves clinical outcome. Insufficient proximal fixation and its consecutive complications remains a major problem of this method.

This study assesses the left ventricular function using a new multislice cine sequence and determines the diagnostic accuracy of stress-induced wall motion abnormalities in patients with coronary artery disease (CAD). ⋯ The multislice sequence results in a substantial reduction of imaging time and breath-hold periods necessary to cover the left ventricle for functional assessment. The multislice sequence yields adequate images, especially for qualitative determination of wall motion abnormalities. Due to the reduced spatial and temporal resolution of the multi-slice sequence, however, some uncertainty concerning the functional parameters has to be taken into account.
