title: [Use of a trans-brachial access during percutaneous treatment of abdominal aortic aneurysms].
abstract: OBJECTIVE
  To evaluate the utility of a trans-brachial access during percutaneous treatment of abdominal aortic aneurysm (AAA).
  
  
  METHODS
  Since September 1998, 43 patients with AAA, have been treated using different types of endoprosthesis. A right trans-brachial access was performed in each patient to facilitate catheterization of the controlateral iliac limb and to make the advancement of the aortic device easier and safer. Moreover an angiographic catheter was positioned at renal arteries through the trans-brachial access. Then several angiographic controls were performed to check if the position of the endoprosthesis was correct. The catheterization of the iliac stump was performed using the retrograde technique in 31 cases (72%) and the anterograde one in 12 cases (27.9%).
  
  
  RESULTS
  The percutaneous trans-brachial access was performed successfully in 42/43 patients. Only one case required surgical exposure. The procedure time for the trans-brachial access ranged from 2-12 min (mean 4.5). Trans-brachial access proved extremely useful in facilitating the aortic device advancement when the iliac-femoral axis was sharply angulated. This access allowed an easier catheterization of controlateral iliac limb. It also permitted several angiographic controls to check the correct position of the endoprosthesis. No pseudoaneurysms, no oculo-cerebral disease, no ischemic phenomena were observed during a 29 month follow-up. Only in 2 cases (4.6%) a small hematoma was noticed the day after the procedure.
  
  
  CONCLUSIONS
  Trans-brachial access proved to be safe and useful during stent-graft positioning.
