[Peri-operative management in patients with thoracic aortic aneurysm complicated with cardiac tamponade].
We retrospectively summarized the peri-operative hemodynamic status and respiratory function in patients with thoracic aneurysms complicated with cardiac tamponade (Tamponade Group; n = 6) in comparison with patients complicated with hemorrhagic pericardial effusion without symptom of cardiac tamponade (Effusion Group; n = 10). There were no difference with regard to preoperative heart rate, pericardial effusion quantity, frequency of emergent operation and operation time. Preoperative hemodynamic status was worse in Tamponade Group than in Effusion Group. The cardiac indices of 12 h, 24 h, 48 h after operation in Tamponade Group were 2.60 +/- 0.60, 2.29 +/- 0.42, 1.95 +/- 0.33 l/min/m2 respectively, those were not different in Effusion Group. The differences between O2 tension in alveolar and arterial blood O2 tension (A-aDO2) and oxygenation indices (OI) of 12 h and 24 h after operation were significantly worse in Tamponade Group than in Effusion Group, but those of 48 h were not different. The operative mortality was 50% in Tamponade Group, and none in Effusion Group. It is very important to maintain hemodynamic status before operation, to perform complete repair (graft replacement) as early as possible and to care intensively after operation for thoracic aortic aneurysm complicated with cardiac tamponade.
