Gefäßchirurgische Ausbildung in endovaskulärer Technik in Lausanne

Between 1995 and 2005, the number of aortic aneurysms treated annually using endovascular techniques (EVAR) increased from 0 to 50, including all aortic stages. Our organization includes a large team of surgeons, a stock of three complete families of endoprostheses (straight, conical and bifurcated), a mobile trolley with accessories (arterial introducer/introducer sheath, guide wire, catheters, balloons, etc.) and an appliance on wheels for intravascular ultrasound examination (IVUS). This appliance, together with a mobile fluoroscopy device (c-arm), allows endovascular aneurysms analysis of every operating room in our institution, usually without angiography or the use of contrast medium. In general, we are therefore not depending on substantial preoperative imaging in order to identify candidates for endovascular aneurysms repair and can treat abdominal and thoracic aortic ruptures without delay. For endovascular aortic aneurysms repair we distinguish between process steps on the one hand (determining indications, imaging of the access vessels, measurement using IVUS and road mapping via fluoroscopy, selection of implant, implant insertion, positioning, setting the implant, determining success, reconstruction of the access vessel and follow-up) and the level of competence on the other (assistant, senior and directing physicians). Our ultrasound supported technique for endovascular aneurysms repair has been successfully brought to other hospitals using an IVUS transporter and telementoring.
