The Aim of this study is to compare the sensitivity and specificity of CT scan and TEE for diagnosis of acute aortic dissection (AD). Materials and Methods: From 01 /2002 to 10/2005, 110 operative procedures on the dilated ascending aorta were performed, 45(40.9%) were operations of acute dissections (Stanford type A classification, De Bakey type I and II). All the patients (pts) with suspected aortic dissection underwent TEE examination, 45/45(100%), CT scanning with contrast 42(93.3%), while aortography was performed in 3(6.6%). Both techniques ( TEE and CT) were compared with intra operative findings (IOF) and sensitivity and specificity was determined by standard formula for five parameters: aortic dilatation, false lumen and intimal flap, coronary involvement, pericardial effusion, and aortic regurgitation. Mean age 54,3±10,39 (range 38 to 74), with preoperative status: shock and metabolic disorders 24(53.3%) cardiac tamponade 8(17.7%), neurological abnormalities 10(22.2%), hypertension 36(80,1 %). Results: TEE shows 100% sensitivity for all parameters except for coronary involvement 7/12 (58.3%), pericardial effusion (92.3%). CT shows sensitivity of 93.3% for.dilatation, 80% for false lumen, 25% for coronary involvement and 69.2% for effusion. The specificity of TEE was 100% for aortic regurgitation, coronary involvement, pericardial effusion, so was with CT value for the first two parameters. Conclusion : Preoperative TEE is time-effective, exact and accessible method.
