Recently, the material available for endovascular aneurysm repair (covered stents and application systems), real time medical imaging and operator experience have significantly improved. Hence, more and more complex vascular lesions, well beyond the original indications, can now be treated by endovascular surgery. Since 1996 our group has implanted 55 endovascular systems in the clinical setting: 45/55 (80%) for classical indications and 11/55 (20%) for extended indications. In the latter group four different endoprosthetic systems were used according to either their performance and availability or the type of lesion to be treated. For the 11 patients undergoing endovascular procedures with extended indications, 6/11 had thoracic aortic lesions (55%) and 5/11 (45%) had aorto-iliac lesions requiring either progressive embolisation of the internal iliac arteries or suprarenal anchorage. For these extended indications hospital mortality was 0/11 (0%). One patient died after hospital discharge. 1/11 patients (9%) had to be converted to open surgery during the interval between iliac embolisation and endovascular repair. There has been no conversion to open surgery during or after the endovascular procedures. Two major endoleaks were detected (2/11: 18%). One has been corrected by an additional covered stent and endovascular repair is planned for the other one. Spontaneously regressive functional hypoperfusion has been observed in 4/5 patients with progressive internal iliac embolisation. There was no irreversible renal insufficiency. Early results of endovascular aneurysm repair for extended indications are promising. Although the long-term outcome is unknown, it can already be said that traditional open surgery can be avoided for a considerable amount of time in an increasing number of patients.
