This study was designed as a single-center experience. We conducted an analysis of data prospectively collected on a computerized database of all patients undergoing elective thoracic EVAR at our center. Over a 5-year period (June 1999 to December 2004), 103 patients underwent thoracic EVAR. There were 86 men and 17 women with a mean age of 70.1 ± 7.7 years. Four of the 103 patients underwent hybrid procedures for thoracoabdominal aortic aneurysms (TAAs). Because of the presence of possible confounding factors related to the different nature of the disease and to the complexity of each of these tailored surgical and endovascular procedures, these cases were excluded from the cumulative analysis.
