The most common symptom was chest pain and\/or back pain. Nine patients presented with malperfusion and 1 with cardiac arrest, preoperatively. A FET was deployed under hypothermic circulatory arrest and manually fenestrated under direct vision. Single fenestration was made in the FET in 15 patients, 2 fenestrations in 5 patients and a total fenestrated technique in 2 patients. Concomitant procedures were performed in 5 patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The cardiopulmonary bypass, aortic cross-clamp and hypothermic circulatory arrest times were 181\u2009\u00b1\u200949, 106\u2009\u00b1\u200943 and 37\u2009\u00b1\u20097\u2009min, respectively. In-hospital mortality, stroke, or recurrent nerve injury did not occur in any patient. One patient developed paraparesis, which completely recovered at discharge. During the follow-up period (mean 18\u2009\u00b1\u20097\u2009months), 1 patient died of heart failure. Fenestration site occlusion did not occur. Follow-up computed tomography (mean 12\u2009\u00b1\u20096\u2009months postoperatively) revealed that the maximal aortic diameter remained unchanged at the levels of the distal end of the FET, the 10th thoracic vertebra and the coeliac artery; however, the aortic diameter was significantly reduced at the level of the pulmonary artery bifurcation.<\/jats:p>\n               <\/jats:sec>\n
