“…An important risk factor for this high early mortality is the preoperative status of the patients [17]. Chiappini et al [18] demonstrated that pre-existing cardiac disease and pre-operative resuscitation are the leading predictors of hospital death. In our material 41% of the patients from the emergency group had cardiac tamponade before surgery, and almost half were operated on antiplatelet therapy.…”

A b s t r a c tBackground: Surgery of the aortic arch is challenging. Aim:To assess the results of aortic arch surgery. Methods:Analysis of 172 patients operated on arch dissection (emergency group: 97 patients) or aneurysm (elective group: 75 patients) between 2007 and 2014. Arch surgery was defined as a procedure requiring circumferential anastomosis at the level of the aortic arch or the descending aorta with the use of techniques of brain protection (deep hypothermic circulatory arrest [DHCA] or selective antegrade cerebral perfusion [SACP]) and/or debranching of at least one supra-aortic vessel.Results: Men predominated in both groups (> 70%). Men were younger in the emergency group (55 vs. 66 years; p < 0.008). The operative risk was higher in the emergency group (19.2% vs. 12.5%; p < 0.001). Forty-nine per cent of the patients from the emergency group and 5% from the elective group were operated with antiplatelet therapy (p < 0.001). Extended hemiarch procedure was performed in 79% (n = 77) in the emergency and 76% (n = 57) in the elective group. Total arch replacement was performed in 19 (21%) patients from the emergency and 18 (24%) patients from the elective group. In these patients debranching was performed in 68% of the emergency patients group and in 67% of the elective group. Elephant trunk procedure (classic/frozen) was performed in 53% (n = 10) from the emergency and in 78% (n = 14) of patients from the elective group. Aortic valve sparing surgery was performed in 20% of patients from the emergency and 9% from the elective group (p = 0.063). DHCA was performed in 58% (n = 43) of patients from the elective group and 39% (n = 37) from the emergency group. SACP was performed in 61% (n = 58) of patients from the emergency and 42% (n = 31) from the elective group. Thirty-day mortality in the emergency group reached 33% (n = 32), and in the elective group 15% (n = 11; p = 0.007). In multivariate analysis, predictors of death in the emergency group were: Logistic EuroSCORE above 19.5%, extracorporeal circulation time above 228 min, and postoperative acute renal failure (ARF); and in the elective group: DHCA time above 26 min, rethoracotomy due to bleeding, and ARF. Follow-up was completed in 100% of patients in terms of vital status. The mean follow-up time of the patients from the emergency group was 24.3 ± 27.10 (min 0, max 92) months, and from the elective group 30.3 ± 24.5 (min 0, max 99) months. During the follow-up period all-cause mortality in the emergency group was 43% (n = 42/97), and in the elective group it was 36% (n = 27/75). Conclusions:Early mortality in the emergency group was higher, while long-term mortality did not differ among the groups. Postoperative ARF is a critical predictor of mortality in both groups.

ompared to the relatively favorable in-hospital outcomes of acute type B aortic dissection, 1,2 acute type A aortic dissection (AAAD) remains one of the most serious cardiovascular diseases associated with a high mortality. The latest report from the International Registry of Acute Aortic Dissection Investigators group indicated that in-hospital mortality remains high (163 of 682 patients (23.9%) with AAAD treated surgically between 1996 and 2003). 3 With such critical illness, some patients require prolonged mechanical ventilation (PMV) after surgery. Compared with patients who undergo other cardiac surgeries, patients with AAAD are more likely to suffer preoperative hemodynamic instability, organ malperfusion, and prolonged cardiopulmonary bypass (CPB) during surgery. In addition, re-exploration for bleeding and neurological deficits are common postoperative complications in these patients. 4 All these factors can contribute to PMV after AAAD surgery. 5 Another factor related to the PMV is systemic inflammatory response-related lung injury evoked by acute aortic dissection. 6,7 A number of studies regarding PMV following cardiac surgery have examined its predictors or its influence on clinical outcomes and costs. [8][9][10][11][12][13][14][15][16][17] However, little is known about PMV following AAAD surgery. The aim of this retrospective study was to identify predictors of PMV following AAAD surgery and to assess the influence of PMV on the short and long-term postoperative courses. MethodsFrom January 1997 through to December 2006, 243 consecutive patients with AAAD underwent emergency surgery at our hospital. Aortic dissection was diagnosed by means of enhanced computed tomography scan or echocardiography, and transesopageal echocardiography was used for confirmation when possible. In all patients, emergency surgery was performed within 14 days after the onset of symptoms; 90% of these surgeries were performed within 48 h. So that we could focus on PMV, 10 patients who died within 48 h after surgery were excluded from the study. Death within 48 h after surgery was due to profound cardiac failure (8 patients) or refractory bleeding (2 patients). The remaining 233 patients (120 men, 113 women, mean age: 63.4±11.2 years) were divided into 2 groups according to the duration of mechanical ventilation: those who were tracheally extubated within 48 h after admission to the intensive care unit (ICU) (group A, n=149) and those who required mechanical ventilation for more than 48 h (group B, n=84). Patients who were reintubated within 24 h after extubation were considered to have an interrupted period of ventilation. To identify the independent predictors for PMV, we compared 48 perioperative factors (25 preoperative factors and 23 intra or postoperative factors) between the 2 groups. Mortality and morbidity, length of the ICU and hospital stays, and long-term survival were compared
