Abstract OBJECTIVES Immediate surgical repair for type A aortic dissection is gold standard and at most centres is performed by the surgeon on call during night-time and weekends. The objective was to evaluate whether emergency surgery during night-time or weekends has an influence on 30-day mortality. METHODS In 319 patients undergoing surgery for type A aortic dissection, skin incision was documented. Patients were divided into 2 groups according to the time point of skin incision (05:00 a.m. to 07:00 p.m. = daytime group; 07:01 p.m. to 04:59 a.m. = night-time group). We also noted whether their surgeries were started on weekdays (Monday 00:00 to Friday 23:59) or weekends (Saturday 00:00 to Sunday 23:59). RESULTS The median age was 61 years (interquartile range 49–70) and 69.6% (n = 222) were male. Almost 50% (n = 149) of patients presented in a critical preoperative state. Forty-one percent of patients (n = 131) underwent night-time surgery. There were no differences in baseline data, time from onset of symptoms to surgery or surgical treatment between groups, except from preferred femoral access for arterial cannulation during night-time. Advanced age [odds ratio 1.042, 95% confidence interval (CI) 1.014–1.070], preoperative malperfusion syndrome (odds ratio 2.542, 95% CI 1.279–5.051) and preoperative tamponade (odds ratio 2.562, 95% CI 1.215–5.404) emerged as risk factors for 30-day mortality. Night-time or weekend surgery did not have any impact on 30-day mortality when covariates were considered. CONCLUSIONS Based on the natural course of the disease and our results, surgery for type A aortic dissection should be performed as an emergency surgery regardless of time and day.

AbstractStanford Type A aortic dissection is a rapidly progressing disease process that is often fatal without emergent surgical repair. A small proportion of Type A dissections go undiagnosed in the acute phase and are found upon delayed presentation of symptoms or incidentally. These chronic lesions may have a distinct natural history that may have a better prognosis and could potentially be managed differently then those presenting acutely. The method of repair depends on location and extent of the false lumen, as well as involvement of critical structures and branch arteries. Surgical repair techniques similar to those employed for acute dissection management are currently first-line therapy for chronic cases that involve the aortic valve, sinuses of Valsalva, coronary arteries, and supra-aortic branch arteries. In patients with high-risk for surgery, endovascular repairs have been successful, and active development of delivery systems and grafts will continue to enhance outcomes. We present two cases of chronic Type A aortic dissection and review the current literature.

Type A Aortic Dissection

Background Female sex is known to have increased perioperative mortality in cardiac surgery. Studies reporting effects of sex on outcome following surgical repair for acute Type A aortic dissection (ATAAD) have been limited by small cohorts of heterogeneous patient populations and have shown diverging results. This study aimed to compare perioperative characteristics, operative management, and postoperative outcome between sexes in a large and well-defined cohort of patients operated for ATAAD. Methods The Nordic Consortium for Acute Type A Aortic Dissection study included patients with surgical repair of ATAAD at eight Nordic centers between January 2005 and December 2014. Independent predictors of 30-day mortality were identified using multivariable logistic regression. Results Females represented 373 (32%) out of 1,154 patients and were significantly older (65 ± 11 vs. 60 ± 12 years, p < 0.001), had lower body mass index (25.8 ± 5.4 vs. 27.2 ± 4.3 kg/m2, p < 0.001), and had more often a history of hypertension (59% vs. 48%, p = 0.001) and chronic obstructive pulmonary disease (8% vs. 4%, p = 0.033) compared with males. More females presented with DeBakey class II as compared with males with dissection of the ascending aorta alone (33.4% vs. 23.1%, p = 0.003). Hypothermic cardiac arrest time (28 ± 16 vs. 31 ± 19 minutes, p = 0.026) and operation time (345 ± 133 vs. 374 ± 135 minutes, p < 0.001) were shorter among females. There was no difference between the sexes in unadjusted intraoperative death (9.1% vs. 6.7%, p = 0.17) or 30-day mortality (17.7% vs. 17.4%, p = 0.99). In a multivariable analysis including perioperative factors influencing mortality, no difference was found between females and males in 30-day mortality (odds ratio: 0.92, 95% confidence interval: 0.62–1.38, p = 0.69). Conclusions This study found no association between sex and early mortality following surgery for ATAAD, despite females being older and having more comorbidities, yet also presenting with a less widespread dissection than males.
