We evaluated the impact of major complications on clinical outcome in a series of patients undergoing endovascular repair (EVAR) of descending thoracic aorta. From March 2001 to June 2005, 51 patients underwent EVAR for descending aortic diseases. Thirty-five were treated in emergency (60.7%) and 41 (80.4%) were in III-IV ASA class. There were no deaths, surgical conversion or paraplegia. A neurologic complication occurred in one patient (1.9%). Eleven major systemic complications occurred in 5 patients. One patient showed a primary type I endoleak at discharge, resolved spontaneously after 9 months. Three (5.9%) vascular injuries occurred during the endovascular procedure, requiring an emergency rescue iliac-femoral artery bypass. At follow-up (29+/-14 months), there was an overall mortality rate of 5.1% (3/51); 2 deaths (3.9%) were procedure related. Two secondary EVARs (3.9%) were successfully performed, one for a late type I endoleak six months after EVAR in a traumatic patient, and a second for a late rupture distally to the stent-graft implanted 36 months before in an acute type-B dissected patient. EVAR for descending aortic diseases is associated with decreased mortality and complications, however, long-term follow-up and additional studies are mandatory to detect late failure and to confirm clinical safety of this procedure

Abstract
We evaluated the impact of major complications on clinical outcome in a series of patients undergoing endovascular repair (EVAR) of descending thoracic aorta. From March 2001 to June 2005, 51 patients underwent EVAR for descending aortic diseases. Thirty-five were treated in emergency (60.7%) and 41 (80.4%) were in III-IV ASA class. There were no deaths, surgical conversion or paraplegia. A neurologic complication occurred in one patient (1.9%). Eleven major systemic complications occurred in 5 patients. One patient showed a primary type I endoleak at discharge, resolved spontaneously after 9 months. Three (5.9%) vascular injuries occurred during the endovascular procedure, requiring an emergency rescue iliac-femoral artery bypass. At follow-up (29+/-14 months), there was an overall mortality rate of 5.1% (3/51); 2 deaths (3.9%) were procedure related. Two secondary EVARs (3.9%) were successfully performed, one for a late type I endoleak six months after EVAR in a traumatic patient, and a second for a late rupture distally to the stent-graft implanted 36 months before in an acute type-B dissected patient. EVAR for descending aortic diseases is associated with decreased mortality and complications, however, long-term follow-up and additional studies are mandatory to detect late failure and to confirm clinical safety of this procedureI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
