Acute Aortic Dissection during Pregnancy: Hideous Clinical Quandaries with Young Lives on the Line—The Role of Hereditary Genetic Syndromes

Objective: Acute aortic dissection is a rare but frequently fatal aortic catastrophe with high morbidity and mortality. Especially in pregnant patients, acute dissection is often misdiagnosed putting two lives on the line. Due to its scarcity, only case reports have been reported. The aim of this study is to analyze the time of aortic dissection during the course of pregnancy and the outcome of emergency surgery in pregnant women with and without hereditary connective tissue disorder. Methods: We retrospectively reviewed all acute aortic dissections (type A and B) who underwent emergency aortic surgery at our institution between 1994 and 2022 and identified 13 patients with acute aortic dissection during pregnancy or directly postpartum. Mann–Whitney U and Fisher’s exact tests were used for statistical analysis. Results: Of the 13 included patients, 5 had a genetic syndrome. These patients were significantly younger at the time of dissection and at an earlier stage of pregnancy (second trimester). Even though operative and in-house mortality was zero, we lost one patient on postoperative day 14 due to rupture of the aortic root after transfer to another hospital. Survival of neonates was 77% including two aborted pregnancies. Conclusions: Surgical treatment of acute aortic dissection during pregnancy can be performed with excellent operative mortality for the mothers and satisfying survival of their neonates. In patients with genetic syndrome, dissection occurs during the early second trimester, whereas non-syndromic patients experience acute dissection in the late third trimester. Long-term follow-up is essential for timely re-intervention, if needed.

Recognition and initial management of acute aortic dissection.

Acute aortic dissection is a cardiovascular emergency that should be recognised on presentation in the Emergency Department (ED) because clinical outcome is time-dependent. In suspected cases of acute aortic dissection, immediate imaging with chest computed tomography scan followed by transthoracic echocardiography (TTE) is essential to confirm diagnosis. Immediate medical management is aimed at controlling the heart rate (60-80 beats/min), systolic blood pressure (100-120 mmHg) and pain. Patients with Type A acute aortic dissection should immediately be referred to the cardiothoracic surgeons for emergency aortic surgery while those with Type B acute aortic dissection should be referred to the vascular surgeons for surgical/endovascular interventions if indicated.

A challenging case of emergency redo surgery for acute type A aortic dissecting aneurysm of ascending and aortic arch with frozen elephant trunk following aortic root replacement

Redo ascending and aortic arch surgeries following previous cardiac or aortic surgery are associated with high risk of morbidity and mortality due to multiple factors included sternal re-entry injury, extensive aortic arch surgery, emergency aortic surgery, prolonged cardiopulmonary bypass duration, poor heart function, and patients with older age. Therefore, appropriate surgical strategies are important. We report a case of a 72-year-old gentleman with previous surgery of aortic root replacement who presented with acute Type A aortic dissecting aneurysm of ascending and aortic arch complicated with left hemothorax, which was successfully treated by emergency redo aortic surgery with frozen elephant trunk (FET) technique.

Early outcomes of a triple-branched stent graft implantation in elderly patients with acute type a aortic dissection

PurposeOlder patients with acute type A aortic dissection (ATAAD) have higher risk of mortality than that of younger patients when a total arch reconstruction (TAR) is required. Triple-branched stent graft (TBSG) implantation is a novel technique for TAR. However, early outcomes of a TBSG implantation in older patients have not been reported. This study aimed to evaluate the early outcomes of the TBSG technique in older patients with ATAAD.MethodsFrom February 2015 to December 2020, 640 patients who simultaneously underwent an emergent open aortic surgery and TBSG implantation for ATAAD were enrolled in this study. They were categorized into the younger (age ≤ 70 years old, n = 573) and older groups (age > 70 years, n = 67). Clinical data of all patients were retrospectively reviewed.ResultThe mean ages of the patients in the younger and older groups were 45.3 ± 9.6 years old and 73.5 ± 3.0 years old, respectively. Preoperative characteristics were similar between the two groups, except for weight and incidence of moderate or greater aortic regurgitation, which were lower in the older group than those in the younger group. Surgical procedure and duration (i.e., duration for cardiopulmonary bypass, aortic cross-clamp, selected cerebral perfusion, and total circulation arrest) were comparable between the two groups (p > 0.05). Patients in the older group had higher incidence of dialysis for acute kidney injury and longer ICU stay compared with those in the younger group. However, the incidences of 30-day mortality (5.1% in younger group vs. 7.5% in older group, p = 0.407) and other major complications (i.e., neurological adverse events) were similar between the two groups.ConclusionTBSG implantation for ATAAD resulted in an acceptable mortality rate in patients above 70 years old, thus, it could be a feasible surgical procedure to perform in older patients with ATAAD when a TAR is required.

Risk factor prediction of severe postoperative acute kidney injury at stage 3 in patients with acute type A aortic dissection using thromboelastography.

Perioperative blood transfusions and postoperative drainage volume not only are the commonly recognized risk factors for acute kidney injury (AKI) but also are indirect indicators of coagulopathy in patients with acute type A aortic dissection (ATAAD). However, standard laboratory tests fail to accurately reflect and assess the overall coagulopathy profile in patients with ATAAD. Thus, this study aimed to explore the association between the hemostatic system and severe postoperative AKI (stage 3) in patients with ATAAD using thromboelastography (TEG). We selected 106 consecutive patients with ATAAD who underwent emergency aortic surgery at Beijing Anzhen Hospital. All participants were categorized into the stage 3 and non-stage 3 groups. The hemostatic system was evaluated using routine laboratory tests and TEG preoperatively. We undertook univariate and multivariate stepwise logistic regression analyses to determine the potential risk factors for severe postoperative AKI (stage 3), with a special investigation on the association between hemostatic system biomarkers and severe postoperative AKI (stage 3). The receiver operating characteristic (ROC) curves were generated to assess the predictive ability of hemostatic system biomarkers for severe postoperative AKI (stage 3). A total of 25 (23.6%) patients developed severe postoperative AKI (stage 3), including 21 patients (19.8%) who required continuous renal replacement therapy (RRT). Multivariate logistic regression analysis demonstrated that the preoperative fibrinogen level (OR, 2.02; 95% CI, 1.03 to 3.00; p = 0.04), platelet function (MA level) (OR, 1.23; 95% CI, 1.09 to 1.39; p = 0.001), and cardiopulmonary bypass (CPB) time (OR, 1.01; 95% CI, 1.00 to 1.02; p = 0.02) were independently associated with severe postoperative AKI (stage 3). The cutoff values of preoperative fibrinogen and platelet function (MA level) for predicting severe postoperative AKI (stage 3) were determined to be 2.56 g/L and 60.7 mm in the ROC curve [area under the curve (AUC): 0.824 and 0.829; p < 0.001]. The preoperative fibrinogen level and platelet function (measured by the MA level) were identified as potential predictive factors for developing severe postoperative AKI (stage 3) in patients with ATAAD. Thromboelastography could be considered a potentially valuable tool for real-time monitoring and rapid assessment of the hemostatic system to improve postoperative outcomes in patients.

A Novel Negative Pressure Therapy Technique to Manage a Colo-Cutaneous Fistula following Emergency Aortic Surgery

Negative pressure wound therapy (NPWT) is a well-established technique for managing the open abdominal wound. The decision to intentionally leave an abdominal incision open may be required in the aftermath of surgery for intra-abdominal sepsis or where there is concern regarding abdominal compartment syndrome (ACS). Untreated ACS following elective, or emergency abdominal aortic aneurysm repair (AAA) is associated with mortality rates of up to 60% [1]. Management of the open abdomen, particularly in obese patient, is challenging and labour-intensive. The aim of wound management in this setting is to contain drainage, manage the peri-wound skin and facilitate closure of the wound. This case report discusses the successful management of a complex abdominal wound in a morbidly obese patient complicated by a colo-cutaneous fistula following emergency abdominal aortic aneurysm repair.

Clinical outcomes of mild versus moderate hypothermic circulatory arrest with antegrade cerebral perfusion in adult aortic arch surgery: A systematic review and meta-analysis.

In adult aortic arch surgery, moderate hypothermic circulatory arrest (HCA) with selective antegrade cerebral perfusion (SACP) (MoHACP) is widely used, but the application of mild HCA with SACP (MiHACP) is still controversial. This meta-analysis aimed to compare clinical outcomes using MiHACP or MoHACP. Studies comparing outcomes of MiHACP or MoHACP in adult aortic arch surgery were searched from four databases from inception through April 2022. Primary outcomes were postoperative permanent neurological deficit (PND), temporary neurological deficit (TND), and mortality. Secondary outcomes included other common complications. Meta-analysis was conducted using a random-effects model in all cases. Eleven comparative studies were included, with 1555 patients in MiHACP group and 1499 patients in MoHACP group, and the mean HCA temperature were 29.4°C and 24.8°C, respectively. Postoperative PND, TND, mortality, paraplegia, dialysis, tracheotomy, reexploration for bleeding, and chest tube drainage volume were comparable in the two groups (p > 0.05). Ventilator time, intensive care unit and in-hospital length of stay were shorter in MiHACP group (p < 0.05). Outcomes were also comparable or had some benefits in MiHACP group when subgroup analyses were conducted according to hemiarch or total arch replacement, unilateral or bilateral SACP, HCA time, emergency aortic dissection surgery, and concomitant procedure. The present meta-analysis showed acceptability of MiHACP in adult aortic arch surgery. Results need to be taken with caution as moderate risk of bias and very low quality of evidence were observed in this meta-analysis. Randomized controlled trials are needed for further analysis.

A Rare Case Report of Ruptured Sinus of Valsalva Aneurysm

&lt;p&gt;主動脈竇動脈瘤是一種罕見的心臟結構病變，因具非特異性表徵及困難診斷，容易導致高死亡風險。本案例是一位53歲男性患者，因急性胸痛入院治療，藉由實驗室檢查發現心肌酵素升高、D-二聚體升高，心電圖檢查為aVR導程ST段上升、於第I、II、V4~6導程出現ST-T波段變化，初步診斷為左冠狀動脈主幹心肌梗塞，立即行冠狀動脈攝影檢查發現無異常。個案出現胸痛合併心因性休克之症狀，從中排除主動脈剝離、肺栓塞、心包填塞等診斷，深入檢視病史紀錄及影像報告，發現心臟超音波、胸部電腦斷層及冠狀動脈血管攝影檢查有由左流向右心室的瘻管分流，最終確診為主動脈竇動脈瘤破裂。患者緊急接受右冠狀竇動脈瘤修補及主動脈瓣置換手術治療後，胸痛、休克狀況改善且左心室功能恢復，術後預後良好。在面對急性胸痛合併血液動力學不穩定的患者時，除了須考慮症狀相關的疾病診斷外，當聽診發現S1及S2連續性心雜音時，建議將主動脈竇動脈瘤破裂列入考慮，以掌握治療處置之重要時機。&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;Aneurysm of the sinus of Valsalva is a rare cardiac anomaly due to the nonspecific symptoms and dif-ficult confirmation of diagnosis leading to high mortality. This report describes the case of a 53-year-old man who had suffered from acute chest pain. The electrocardiogram showed the ST segment ele-vation in lead aVR and ST-T wave changes in leads I, II and V4-6. Elevated D-dimer levels and cardi-ac enzymes were also observed. Acute myocardial infarction caused by the left main coronary artery obstruction was initial diagnosed. Coronary angiogram was performed immediately and the result indicated non-obstructive coronary artery. However, cardiogenic shock with persistent chest pain was discovered. Aortic dissection, pulmonary thromboembolism and cardiac tamponade were gradually excluded. Through detailed review and analysis of medical history, physical assessment and image ex-aminations with echocardiography, chest computed tomography and coronary angiogram, a ruptured sinus of Valsalva aneurysm was eventually diagnosed based on image examinations which revealed left-to-right shunt communicating with the right-sided heart chambers. The patient received emergen-cy right coronary sinus aneurysm repairment and aortic valve replacement surgery. Symptoms with chest pain and shock gradually disappeared and left ventricular function was restored postoperatively. The patient demonstrated excellent recovery. In facing relevance diagnostics for patients with acute chest pain and hemodynamic instability, a ruptured sinus of Valsalva aneurysm must be considered to endure best treatment timing if heart auscultation reveals S1 and S2 continuous murmurs.&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt;

A 12-year experience of endovascular repair for ruptured abdominal aortic aneurysms in all patients

ObjectiveEndovascular aneurysm repair (EVAR) has been increasingly performed for ruptured abdominal aortic aneurysms (rAAAs). However, multiple randomized trials have failed to demonstrate a survival benefit compared with open aortic surgery. During a 12-year period, 100% of patients without a history of aneurysm surgery had undergone EVAR for a rAAA at Örebro University Hospital, with no emergent open aortic surgery performed. In the present study, we evaluated the mortality and technical success during this “EVAR-only” period. MethodsA single-center, retrospective observational study was conducted. We identified all patients who had presented to Örebro University Hospital with a rAAA between October 2009 and September 2021. Patients with isolated iliac artery, thoracic, and thoracoabdominal aortic ruptures were not included. Patients who had received previous aortic interventions (open or endovascular) and patients who had received palliative treatment instead of surgical intervention were also excluded. The patient characteristics, perioperative and postoperative data, and mortality rate were investigated. ResultsEVAR had been performed in 100 patients. Preoperative hemodynamic instability had been present in 54 patients (54%), and 18 (18%) had undergone aortic balloon occlusion. The aneurysm location was infrarenal in 89 patients (89%). Bifurcated stent grafts had been used in 97 patients (97%), and adjunct endovascular techniques had been used for 27 patients (27%). Of 98 patients, EVAR had been performed with the patient under local anesthesia for 62 patients (63%). Peri- and postoperative complications at 30 days had occurred in 20 of 100 patients (20%) and 22 of 79 patients (28%), respectively. The overall mortality at 30 days was 27% (27 of 100 patients), and the mortality for those with an isolated infrarenal rAAA was 24% (21 of 89 patients). The overall mortality at 1 year was 39% (39 of 100 patients) and for those with an isolated infrarenal rAAA was 37% (33 of 89 patients). The presence of preoperative hemodynamic instability and the use of ABO were statistically significantly and independently associated with increased 30-day mortality on multivariate logistic regression analysis. ConclusionsAll 100 patients who had undergone surgery for a rAAA had been treated using EVAR and endovascular adjuncts, with a relatively low mortality rate, thus continuing the “EVAR-only” approach. A low proportion of rAAA patients were considered surgically unsuitable. These findings support the applicability of EVAR for the treatment of all rAAAs at suitable centers.

Intraoperative Finding of Anomalous Circumflex Artery Origin in the Dissected Right Coronary Ostium.

Anomalous origin of the left circumflex artery is a rare anatomical variant that may present a unique challenge in emergent aortic surgery.

Safety and efficacy of fibrinogen concentrate in aortic arch surgery involving moderate hypothermic circulatory arrest.

Bleeding is a common complication of cardiac surgery, especially aortic arch surgery involving moderate hypothermic circulatory arrest. Fibrinogen concentrate has been increasingly used to treat coagulopathic bleeding in cardiac surgery, although its effectiveness and safety are unknown. The aim of this prospective study was to investigate the safety and efficacy of fibrinogen concentrate in patients with acute type A aortic dissection. From July 2020 to August 2021, 84 patients with acute type A aortic dissection who underwent emergency aortic arch surgery involving MHCA and whose intraoperative fibrinogen level was less than 1.5g/L were included in this study. Fifty-four patients who were supplemented with fibrinogen concentrate were included in the FC treatment group. Thirty patients were included in the non-FC treatment group. The primary endpoints included the required volumes of individual allogeneic blood products (RBCs, FFP, and PC), volumes of cumulative drainage within 24 and 48h, and total volumes after infusion of FC, as well as reoperation rates due to bleeding. The secondary endpoint for the study was the incidence of serious adverse events from the infusion of FC to day 45. The serious adverse events defined for the evaluation of the safety of FC were death, pulmonary embolism and other thromboembolic or ischaemic events. The clinical data, routine laboratory tests and plasma fibrinogen levels were obtained at 5 time points. We observed rapid increases in the plasma fibrinogen level and subsequent improvement in haemostasis after the administration of fibrinogen concentrate. The mean fibrinogen level increased from 1.36 ± 0.75g/L to 2.91 ± 0.76g/L in the fibrinogen concentrate treatment group. The patients in the fibrinogen concentrate treatment group demonstrated lower volumes of cumulative postoperative drainage and transfused allogeneic blood products than the nonfibrinogen concentrate treatment group. There were no serious adverse events in the fibrinogen concentrate treatment group during hospitalization. Fibrinogen concentrate was effective at increasing the plasma fibrinogen level and significantly reduced the volumes of transfused allogeneic blood products and blood loss in patients with aortic arch surgery. There were no serious adverse events in the patients who received fibrinogen concentrate treatment. The safety and efficacy of fibrinogen concentrate were investigated in acute type A aortic dissection patients with aortic arch surgery. Fibrinogen concentrate was effective at increasing the plasma fibrinogen level and significantly reduced the volumes of transfused allogeneic blood products and blood loss; there were no serious adverse events in the patients who received fibrinogen concentrate treatment.

Comparison between Bretschneider -HTK solution and antegrade cold blood cardioplegia as a method for myocardial protection in thoracic aortic surgery

Background: Cardiac surgeons demand a cardioplegic solution providing extended durations of myocardial protection due to the increasing complexity of cardiac surgical procedures, especially thoracic aortic operations which require extended myocardial ischemic periods. The goal of this study was to assess the safety and efficacy of cold crystalloid single dosage Histidine Tryptophan Ketogultarate (Custodiol) cardioplegia to cold blood multidose cardioplegia in aortic surgery patients. Methods: Our study included 100 elective and emergency aortic surgery patients. Fifty patients received Custodiol cardioplegic solution (group A) and fifty received cold blood cardioplegia (group B). We evaluated post-operative cardiac Troponin I release, postoperative morbidities and mortality. Results: Troponin I peak release, duration of inotropic support &amp; intensive care unit stay were more in the cold blood group. Hemofiltration and intraoperative requirement of blood products transfusion were more in the Custodiol group. No differences were found regarding cross-clamp time, arrhythmias, postoperative ejection fraction and in-hospital mortality. Conclusion: In patients having thoracic aortic surgery, custodiol and cold blood cardioplegic treatments give good myocardial protection. Custodiol usage was linked to lower troponin levels, shorter inotropic support periods, and shorter ICU stays. In terms of early mortality and morbidity, there was no statistically significant difference between the two groups.

Surgical treatment of acute aortic dissection in a patient with SLE and prior antiphospholipid syndrome on therapy for over 30 years: a case report

BackgroundIn patients with systemic lupus erythematosus (SLE), lengthy treatment and long-term steroid use are the main risk factors for developing aortic aneurysms or aortic dissections. In patients with cardiac tamponade, hemodynamic collapse may lead to acute renal and hepatic failure.Case presentationWe report the successful treatment of a 55-year-old woman with SLE since the age of 21. She suddenly felt chest pain approximately 2 weeks before developing fever and vomiting and was admitted to our hospital. Initially, she had severe liver dysfunction and was admitted to the hepatology department, where treatment for fulminant hepatitis was initiated. However, computed tomography (CT) showed an acute aortic dissection (DeBakey type II) and severe bloody pericardial effusion. Therefore, we performed emergency pericardial drainage. Plasma exchange therapy was initiated as emergency aortic surgery was deemed impossible due to impaired liver function tests and coagulation. Ten days later, the patient developed peritonitis due to small bowel perforation, and laparotomy was performed for abscess drainage and perforation closure. She had received steroid pulse therapy at the age of 21. At 40 years of age, she developed deep vein thrombosis due to antiphospholipid antibodies and was prescribed prednisolone. She was ambulatory at 3 months after the onset of acute aortic dissection, and CT revealed a rapidly enlarging true aneurysm in the distal arch. We performed elective aortic surgery. Although there were no antiphospholipid antibodies, surgery could have led to a devastating antiphospholipid syndrome. Therefore, we decided to treat the patient with triple therapy. Methylprednisolone was intravenously administered intraoperatively and at 1 day postoperatively. The patient was discharged without complications after returning to her usual oral prednisolone regimen.ConclusionsThe patient described herein had a systemic circulatory failure due to cardiac tamponade, accompanied by liver failure. This condition is a significant cause of death in patients with aortic dissection-associated SLE and is extremely dangerous. However, multi-specialty intervention helped the patient recover, and she has been attending the outpatient clinic. Aortic surgery requiring hypothermia in SLE patients with antiphospholipid syndrome and a history of thrombocytopenia or thrombosis requires a multi-disciplinary treatment team, including cardiac surgeons and medical experts.

Anterior spinal artery syndrome due to Clostridium septicum aortitis

Anterior spinal artery syndrome due to Clostridium septicum aortitis

The frozen elephant trunk technique in an emergency: THORAFLEX French National Registry offers new insights.

Our goal was to study the immediate outcome after an emergency frozen elephant trunk procedure with a Thoraflex™ Hybrid prosthesis (THP) in patients included in the EPI-Flex national registry and operated on in 21 French centres. All patients operated on in France between April 2016 and April 2019 for acute aortic syndromes and who had an frozen elephant trunk procedure with a THP were included in the study. The main end point was in-hospital mortality. The secondary end point was neuromorbidity, including paraplegia. The evolution of the main end point was monitored using a variable life-adjusted display graph with cumulative sum derivatives in order to stop inclusions in case the observed mortality became out of range compared to an expected mortality between 15% and 20%. Enrolment ended on the scheduled date and included 109 patients. Most cases (54%) were performed at 3 centres, where more than 10 THP each were implanted (10-26). The observed mortality in the large-volume centres (22%) was comparable to that observed in the low-volume centres (20%). The individually risk-adjusted cumulative sum revealed that observed in-hospital mortality was statistically in line with that predicted by the log EuroSCORE. Analysis of the secondary end point revealed 8% cases of paraplegia, all of which appeared after treatment of the thoracic type A aortic dissection. In France, THP for emergency frozen elephant trunk surgery outside high-volume centres did not result in excessive in-hospital deaths. However, a word of caution must be expressed regarding the prevention of medullar ischaemia even in emergency aortic surgery.

Cardiopulmonary bypass time is an independent risk factor for acute kidney injury in emergent thoracic aortic surgery: a retrospective cohort study

BackgroundThoracic aortic surgery and cardiopulmonary bypass are both associated with development of postoperative acute kidney injury. In this study, we undertook to investigate the relationship between cardiopulmonary bypass time and postoperative acute kidney injury in patients undergoing thoracic aortic surgery for acute DeBakey Type I aortic dissection.MethodsAll patients receiving thoracic aortic surgery for acute DeBakey Type I aortic dissection in Beijing Anzhen hospital from December 2015 to April 2017 were included. Cardiopulmonary bypass time was recorded during surgery. Acute kidney injury was defined based on the Kidney Disease Improving Global Outcomes criteria. A total of 115 consecutive patients were eventually analyzed.ResultsThe overall incidence of acute kidney injury was 53.0% (n = 61). The average age was 47.8 ± 10.7 years; 74.8% were male. Mean cardiopulmonary bypass time was 211 ± 56 min. In-hospital mortality was 7.8%. Multivariate logistic regression revealed that cardiopulmonary bypass time was independently associated with the occurrence of postoperative acute kidney injury after adjust confounding factors (odds ratio = 1.171; 95% confidence interval: 1.002–1.368; P = 0.047).ConclusionsCardiopulmonary bypass time is independently associated with an increased hazard of acute kidney injury after thoracic aortic surgery for acute DeBakey Type I aortic dissection. Further understanding of the mechanism of this association is crucial to the design of preventative strategies.

Risk factors of surgical treatment of acute aortic dissection type A (in Russian only)

To evaluate risk factors of surgical treatment of acute aortic dissection type A. Retrospective analysis included 100 patients with acute aortic dissection type A who underwent surgery in 2007-2017. Patients were divided into 2 groups: group I (survivors, n=79) and group II (unfavorable outcomes, n=21). Postoperative in-hospital mortality was 21% (21/100). Preoperative risk factors were cardiac tamponade (p=0.0001), aortic rupture (p=0.0001), impaired coronary blood flow (p=0.0001), renal malperfusion (p=0.0001). Prolonged cardiopulmonary bypass (156.1±37.9 min vs 205.7±91.2 min), surgery time (5.0±1.1 vs. 6.8±2.5 h, p=0.0009) and deep hypothermia (26.1±4.6 min vs 22.4±4.4 min) were the main intraoperative risk factors influencing surgical outcomes in patients who underwent aortic arch repair. Multiple organ failure (p=0.0001), sepsis (p=0.0007), severe postoperative bleeding (p=0.0010) and disseminated intravascular coagulation (p=0.0001) were the main predictors of advanced mortality in postoperative period. Timely surgical treatment in case of cardiac tamponade and aortic rupture is essential to improve survival in patients with acute aortic dissection. Advanced aortic repair including hemi- or total arch replacement should be comprehensively measured because such procedures may be followed by increased postoperative morbidity and mortality after emergency aortic surgery.
