ABSTRACT

Se describe el caso de un paciente de 70 años que consultó por cefalea súbita, tipo trueno, sin alteración del estado de consciencia, acompañada de dolor torácico de una hora de evolución y de baja intensidad. A su ingreso fue enfocado como cefalea en trueno, que es clasificada, en cuanto a la atención, como bandera roja. La medición de troponina fue negativa y una tomografía de cráneo fue leída como normal. Desde el ingreso presentaba signos vitales normales, cuando iba a ser dado de alta se torna hipotenso (completamente asintomático) y por su síntoma cardinal (cefalea), que se asoció a dolor torácico leve y no anginoso, se solicitó angiotomografía toracoabdominal, con la que se demostró aneurisma disecante de la aorta. Con la presentación de este caso, se busca resaltar la importancia en el servicio de urgencias de la asociación de la cefalea tipo trueno, con condiciones vasculares como la disección aórtica.


We describe the case of a 70-year-old patient, who seeks medical advice due to sudden, thunder headache, without alteration of the state of consciousness, accompanied by chest pain of 1 hour of evolution and of low intensity. Upon his admission, the patient was treated as a thunderclap headache, which is considered a red flag. His troponin was negative, and his head tomography was interpreted as normal. From admission he had normal vital signs, but when he was going to be discharged, he became hypotensive (completely asymptomatic) and due to his cardinal symptom (headache) that was asso-ciated with mild non-anginal chest pain, a thoracoabdominal angioCT was requested, with which dissecting aneurysm of the aorta was evidenced. With the presentation of this case, we seek to highlight the importance of the association of thunder-type headache with possible vascular conditions such as aortic dissection in the emergency department.


Descrevemos o caso de uma paciente de 70 anos que consultou por quadro de cefaleia súbita, tipo trovão, sem alteração do estado de consciência, acompanhada de dor torácica de uma hora de evolução e de baixa intensidade. Na admissão, foi tratado como cefaleia em trovoada, que é classificada, em termos de atenção, como bandeira vermelha. A me-dição da troponina foi negativa e uma tomografia de crânio foi lida como normal. Desde a admissão apresentava sinais vitais normais, quando ia receber alta ficou hipotenso (totalmente assintomático) e devido ao seu sintoma cardinal (cefaleia), que se associou a dores torácicas ligeiras e não anginosas, foi solicitada angiografia toracoabdominal, com cujo aneurisma dissecante da aorta foi demonstrado. Com a apresentação deste caso, o objetivo é destacar a importância no pronto-socorro da associação da cefaleia do tipo trovão com afecções vasculares como a dissecção da aorta.

ABSTRACT

BACKGROUND@#Acute type A aortic dissection (ATAAD) and acute type A intramural hematoma (ATAIMH) are life-threatening diseases with high mortality. To better understand their clinical features in the Chinese population, we analyzed the data from the first Registry of Aortic Dissection in China (Sino-RAD) to promote the understanding and management of the diseases.@*METHODS@#All patients with ATAAD and ATAIMH enrolled in Sino-RAD from January 1, 2012 to December 31, 2016 were involved. The data of patients' selection, history, symptoms, management, outcomes, and postoperation complications were analyzed in the study. The continuous variables were compared using the Student's t test for normal distributions and the Mann-Whitney U test for non-normal distributions. Categorical variables were compared using the Chi-square test or Fisher exact test.@*RESULTS@#A total of 1582 patients with ATAAD and 130 patients with ATAIMH were included. The mean age of all patients was 48.4 years. Patients with ATAAD were significantly younger than patients with ATAIMH (48.9 years vs. 55.6 years, P < 0.001). For the total cohort, males were dominant, but the male ratio of patients with ATAAD was significantly higher compared to those with ATAIMH (P = 0.01). The time range from the onset of symptom to hospitalization was 2.0 days. More patients of ATAIMH had hypertension than that of ATAAD (82.3% vs. 67.6%, P < 0.05). Chest and back pain were the most common clinical symptoms. Computerized tomography (CT) was the most common initial diagnostic imaging modality. 84.7% received surgical treatment and in-hospital mortality was 5.3%. Patients with ATAAD mainly received surgical treatment (89.6%), while most patients with ATAIMH received medical treatment (39.2%) or endovascular repair (35.4%).@*CONCLUSIONS@#Our study suggests that doctors should comprehensively use clinical examination and genetic background screening for patients with ATAAD and ATAIMH and further shorten the time range from symptoms onset to intervention, achieving early diagnosis and treatment, thereby reducing the mortality rate of patients with aortic dissection in China. We should standardize the procedures of aortic dissection treatment and improve people's understanding. Meanwhile, the curing and transferring efficiency should also be improved.

ABSTRACT

OBJECTIVES@#To evaluate the relation between single nucleotide polymorphisms (SNPs) of tropoelastin gene and aortic dissection (AD) via identifying SNPs in the tropoelastin gene, and to detect the level of tropoelastin mRNA, elastin and elastic fibers.@*METHODS@#The specimens of the AD group (@*RESULTS@#Seven SNP loci of the tropoelastin gene were detected in these samples. Among them, 5 SNP loci were polymorphic. The frequency of 3 SNP loci[rs2071307 (G/A), rs34945509 (C/T) and rs17855988 (G/C)] was significantly different between the AD group and the control group (all @*CONCLUSIONS@#The polymorphisms of rs2071307 (G/A), rs34945509 (C/T), and rs17855988(G/C) in the tropoelastin gene may eventually affect the synthesis of elastic fibers and they may play an important role in the occurrence of AD.

ABSTRACT

OBJECTIVES@#Thoracoabdominal aortic aneurysm (TAAA) prosthetic vessel replacement is one of the most complex operations in the field of cardiovascular surgery. The key to success of this operation is to prevent and avoid ischemia of important organs while repairing TAAA. This study aims to summarize and analyze the effect of prosthetic vessel replacement under left heart bypass in the treatment of TAAA.@*METHODS@#Data of 15 patients with TAAA who underwent prosthetic vessel replacement under left heart bypass in Xiangya Hospital of Central South University were retrospectively analyzed. According to Crawford classification, there were 2 cases of type I, 8 cases of type II, 3 cases of type III, and 2 cases of type V. There were 14 cases of selective operation and 1 case of emergency operation. All operations were performed under left heart bypass, and cerebrospinal fluid drainage was performed before operation. Left heart bypass was established by intubation of left inferior pulmonary vein and distal abdominal aorta or left femoral artery. The thoracoabdominal aorta was replaced segment by segment. After aortic dissection, the kidneys were perfused with cold crystalloid renal protective solution, and the celiac trunk and superior mesenteric artery were perfused with warm blood.@*RESULTS@#One patient with TAAA after aortic dissection of type A died. During the operation, straight blood vessels were used to repair TAAA, and the celiac artery branches were trimmed into island shape and anastomosed with prosthetic vessels. After the operation, massive bleeding occurred at the anastomotic stoma, then anaphylactic reaction occurred during massive blood transfusion, resulting in death. One patient suffered from paraplegia due to ischemic injury of spinal cord. The other patients recovered well and were discharged. The postoperative ventilation time was (16.5±13.8) h and the postoperative hospital stay was (10±4) d. The amount of red blood cell transfusion was (13±9) U. The patients were followed up for 2 months to 2 years, and the recovery was satisfactory.@*CONCLUSIONS@#The effect of prosthetic vessel replacement under left heart bypass in the treatment of TAAA is good, which is worthy of clinical promotion.

ABSTRACT

Type A aortic dissection (AD) is a critical and severe disease with high mortality. The Sun's operation is a standard surgical method for this kind of disease at present. For the procedure, an elephant trunk stent is inserted into the true lumen of the descending aorta and the aortic arch is replaced. A patient was admitted to the First Hospital of Lanzhou University due to sudden chest and back pain for 6 days. Computed tomography angiography (CTA) showed type A AD. Ascending aorta replacement, Sun's operation, and ascending aorta to right femoral artery bypass grafting were performed. After surgery, the patient's condition was worsened. The digital subtraction angiography (DSA) showed the elephant trunk stent was inserted into the false lumen of AD, leading to the occlusion of the large blood vessel at the distal part of the abdominal aorta and below. Although we performed intima puncture and endovascular aortic repair, the patient was still dead.

ABSTRACT

Abstract Introduction: Acute aortic dissection (AAD) is a devastating surgical emergency, with high operative mortality. Several scoring algorithms have been used to establish the expected mortality in these patients. Our objective was to define the predictive factors for mortality in our center and to validate the EuroSCORE and Penn classification system. Methods: Patients who underwent surgery for AAD from 2006 to 2016 were retrieved from the institution's database. Preoperative, operative and postoperative variables were collected. Observed and expected mortality was calculated by EuroSCORE. Logistic regression analysis and Cox regression analysis were performed to find predictors of operative mortality and survival, respectively. The receiver operating characteristic (ROC) curves were plotted for logistic EuroSCORE, and the area under the ROC curve (AUC) was calculated. Results: 87 patients (27.6% female) underwent surgery for AAD. The mean age was 58.6±9.7 years. Expected and observed operative mortality was 25.8±15.1% and 20.7%, respectively. Penn Aa, Ab and Abc shared similar observed/expected (O/E) mortality ratio. The only independent predictor of operative mortality (OR: 3.63; 95% CI: 1.19-11.09) and survival (HR: 2.6; 95% CI: 1.5-4.8) was female gender. EuroSCORE showed a very poor prediction capacity, with an AUC=0.566. Conclusion: Female gender was the only independent predictor of operative mortality and survival in our institution. EuroSCORE is a poor scoring algorithm to predict mortality in AAD, but with consistent results for Penn Aa, Ab and Abc.

ABSTRACT

Abstract We present a case of a 36-year-old male patient with known arthrogryposis multiplex congenita and an associated unicuspid aortic valve. The patient later developed a significant aneurysm of the ascending aorta, however refused surgical intervention and missed follow-up appointments for 5 years. During an urgent, general practitioner-initiated transthoracic echocardiography follow-up, a chronic type A aortic dissection was diagnosed as a result of progressive aortic dilatation. Due to the stationary pressure gradients and non-progressive leaflet fibrosis, a conservative approach for to the unicuspid aortic valve was chosen, combined with replacement of the ascending aorta and partial replacement of the aortic arch.

ABSTRACT

Abstract Introduction: The aim of this study is to compare postoperative outcomes and follow-up of two different modifications facilitating surgical technique of frozen elephant trunk (FET) procedure for complex thoracic aortic diseases - zone 0 (fixation with total arch debranching) and zone 3 (fixation with islet-shape arch repair). Methods: From May 2012 to December 2018, data were collected from 139 patients who had been treated with FET procedure for complex thoracic aortic diseases. According to Ishimaru arch map, patients with proximal anastomotic site of hybrid graft at zone 0 and zone 3 were grouped as Group A (n=58, 41.7%) and Group B (n=81, 58.3%), respectively. Mean age of study population was 54.7±11.4 years, and 111 patients were male (79.9%). Results: In-hospital mortality was observed in 20 (14.4%) patients (n=12, acute type A aortic dissection, and n=4, previous aortic dissection surgery). There was no significant difference between both groups in terms of in-hospital mortality. Four patients from Group A and three patients from Group B had permanent neurological deficit (P=0.32). Three patients from both groups had transient spinal cord ischemia (P=0.334). Although mean total perfusion time was longer in Group A, duration of visceral ischemia, when compared with Group B, was shorter (P<0.001). Five-year survival rate was 82.8% in Group A and 81.5% in Group B (P=0.876). Conclusion: FET procedure is a feasible repair technique in the treatment of complex aortic diseases, providing satisfactory early results. Because of its advantageous aspects, zone 0 fixation with debranching is the preferred technique in our clinic.

ABSTRACT

SUMMARY OBJECTIVE: To investigate the protective effect and mechanism of dexmedetomidine (Dex) on perioperative myocardial injury in patients with Stanford type-A aortic dissection (AD). METHODS: Eighty-six patients with Stanford type-A AD were randomly divided into Dex and control groups, with 43 cases in each group. During the surgery, the control group received the routine anesthesia, and the Dex group received Dex treatment based on routine anesthesia. The heart rate (HR) and mean arterial pressure (MAP) were recorded before Dex loading (t0), 10 min after Dex loading (t1), at the skin incision (t2), sternum sawing (t3), before cardiopulmonary bypass (t4), at the extubation (t5), and at end of surgery (t6). The blood indexes were determined before anesthesia induction (T0) and postoperatively after 12h (T1), 24h (T2), 48h (T3), and 72h (T4). RESULTS: At t2 and t3, the HR and MAP in the Dex group were lower than in the control group (P < 0.05). Compared with the control group, in the Dex group at T1, T2, and T3, the serum creatine kinase-MB, cardiac troponin-I, C-reactive protein, and tumor necrosis factor-α levels were decreased, and the interleukin-10 level, the serum total superoxide dismutase, and total anti-oxidant capability increased, while the myeloperoxidase and malondialdehyde levels decreased (all P < 0.05). CONCLUSIONS: Dex treatment may alleviate perioperative myocardial injury in patients with Stanford type-A AD by resisting inflammatory response and oxidative stress.


RESUMO OBJETIVO: Investigar o efeito protetor e o mecanismo da dexmedetomidina (Dex) na lesão perioperativa do miocárdio em doentes com dissecação aórtica Tipo A de Stanford (AD). MÉTODOS: Oitenta e seis pacientes com o Tipo A de Stanford foram aleatoriamente divididos em Dex e grupos de controle, 43 casos em cada grupo. Durante a cirurgia, o grupo de controle recebeu a anestesia de rotina, e o grupo Dex recebeu tratamento Dex baseado na anestesia de rotina. A frequência cardíaca (AR) e a pressão arterial média (MAP) foram registradas no momento anterior ao Dex carregar (t0), 10 minutos após o Dex carregar (t1), incisão cutânea (t2), serragem de esterno (t3), antes do bypass cardiopulmonar (t4), extubação (t5) e fim da cirurgia (t6). Os índices de sangue foram determinados no momento antes da indução da anestesia (T0) e no pós-operatório 12 horas (T1), 24 horas (T2), 48 horas (T3) e 72 horas (T4). RESULTADOS: Em T2 e t3, o RH e o MAP do grupo Dex foram inferiores ao grupo de controle (p<0,05). Em comparação com o grupo de controle, no grupo Dex em T1, T2 e T3, os níveis séricos de creatina quinase-MB, troponina-I, proteína C-reativa e necrose do fator-α do tumor diminuíram, o nível interleucina-10 aumentou, o desalinhamento total do superóxido sérico e a capacidade antioxidante total aumentaram e os níveis de mielopeperóxido e malondialdeído diminuíram (todos p<0,05). CONCLUSÃO: O tratamento com Dex pode aliviar a lesão do miocárdio perioperativo em doentes com o Tipo A de Stanford por resistência à resposta inflamatória e ao estresse oxidativo.

ABSTRACT

Abstract Objective: To describe our experience of nine patients with extra-anatomical bypass for clinically ischemic distal limb during repair of acute Type A aortic dissection (ATAAD). Methods: We retrospectively examined a series of nine patients who underwent surgery for ATAAD. We identified a subset of the patients who presented with concomitant radiographic and clinical signs of lower limb ischemia. All but one patient (axillobifemoral bypass) underwent femorofemoral crossover grafting by the cardiac surgeon during cooling. Results: One hundred eighty-one cases of ATAAD underwent surgery during the study period with a mortality of 19.3%. Nine patients had persistent clinical evidence of lower limb ischemia (4.9%) and underwent extra-anatomical bypass during cooling. Two patients underwent additional fasciotomies. Mean delay from symptoms to surgery in these nine patients was 9.5 hours. Two patients had bilateral amputations despite revascularisation and, of note, had long delays in presentation for surgery (> 12 hours). There were no mortalities during these inpatient episodes. Outpatient radiographic follow-up at the first opportunity demonstrated 100% patency. Conclusion: Our experience suggests that, during complicated aortic dissection, limb ischemia may have a devastating outcome including amputation when diagnosis and referral are delayed. Early diagnosis and surgery are crucial in preventing this potentially devastating complication.

ABSTRACT

Abstract Introduction: Cocaine use is known to be associated with an increased risk for vascular diseases. It is likely to trigger or increase the risk for an aortic dissection. We conducted an analysis of 45 cases of cocaine-related aortic dissection to further characterize the clinical features and outcomes of this patient cohort. Methods: Our study cohort of 45 patients consisted of 11 cases from our institutional database and 34 published case reports. Results: The observed cases of acute aortic dissection related to cocaine use showed a high proportion of young (41.3±8.67 years) and male (88.9%) patients. Most of the cases (75%) were classified as Stanford type A. Also, in 75% of the cases, cocaine use was prevalent for more than one year. Median time from last cocaine use to onset of symptoms was one hour. In-hospital mortality was 21.4%, while additional 11.9% of the cases died before arriving at the hospital. Conclusion: Acute aortic dissection related to cocaine use occurs in predominantly young male patients and has a dismal outcome when compared to all comer series.

ABSTRACT

Abstract Objective: To detect the potential risk factors associated with early mortality in patients who received extensive surgical management, in the form of total arch replacement plus frozen elephant trunk and arch debranching (hybrid repair technique), for acute type A aortic dissection. Methods: The clinical and surgical data of 452 surgically treated patients with acute type A aortic dissection at our center, between March 2010 and December 2016, have been retrieved. Uni and multivariate logistic regression analyses were carried out to detect the effect of various preoperative demographics and different perioperative variables on early mortality. Results: Overall 30-day mortality occurred in 70 out of 452 patients (15.4%). The principal causes of death were multiple organ failure (n=38), cardiac failure (n=18), and severe pulmonary infection (n=10). Risk factors for early mortality were identified with multivariate analysis. Preoperatively, overweight (P<0.025), alcohol drinking (P<0.002), coronary artery disease (P<0.014), hemodynamic shock (P<0.006), and elevated white blood cells count (P<0.002) were associated with higher mortality rate. Postoperatively, prolonged operation time (P<0.008), stroke (P<0.0001), and acute renal dysfunction (P<0.0001) were highly associated with death. Conclusion: Considering the advantages of extensive surgical management for acute type A aortic dissection over the other less aggressive surgical approaches, it should be advised whenever indicated, provided that being carried out by experts in the field of adult aortic surgery in high-volume centers. The surgeon should be aware of the patient's preoperative comorbidities and other risk factors for early mortality, in particular, prolonged operation time.

ABSTRACT

Abstract Total arch replacement and stent trunk were performed for two patients. One of these underwent a total bilateral carotid artery replacement in anatomical position while the other underwent partial carotid artery dissection. The first patient demonstrated no neurological complication after surgery and a postoperative computed tomography angiography (CTA) showed bilateral common carotid artery patency. However, the second patient had neurological dysfunction after surgery, while a postoperative CTA showed occlusion of the left common carotid artery. Anatomical replacement for a common carotid artery dissection with thrombus has the potential to significantly improve cerebral perfusion and reduce postoperative neurological complications.

Conclusión: La reparación de una disección auricular con parche es una buena alternativa de tratamiento en estos casos.


Introduction: Left atrial dissection is an infrequent but potentially fatal complication of cardiac surgery. It is frequently associated with mitral valve surgery, both its repair and replacement, with an incidence of 0.16%. However, other procedures such as percutaneous interventions can also be predisposing factors. Objectives: To report the surgical resolution of a left atrial dissection case and contribute to the national casuistry. Materials and Method: Clinical, imaging and photographic record of the clinical episode. Results: A patient who underwent retrograde radiofrequency ablation during the post-interventional period with heart failure and whose study identifies an atrial dissection. Mitral ring repair, subvalvular apparatus repair and pericardial patch was performed, the patient evolves with favorable clinical and sonographic evolution. Discussion: The treatment of this entity should be analyzed case by case, the etiology related to percutaneous procedures is different to that caused by mitral valve surgery and this should be considered when choosing a therapeutic option. Conclusion: Repairing an atrial dissection with a patch is a good alternative in these cases.

ABSTRACT

Abstract Introduction: One of the most important points of the acute type A aortic dissection surgery is how to perform cannulation regarding cerebral protection concerns and the conditions of arterial structures as a pathophysiological consequence of the disease. Objective: In this study, femoral and axillary cannulation methods were compared in acute type A aortic dissection operations. Methods: The study retrospectively evaluated 52 patients who underwent emergency surgery for acute type A aortic dissection. Patients without malperfusion according to Penn Aa classification were chosen for preoperative standardization of the study groups. The femoral arterial cannulation group was group 1 (n=22) and the axillary arterial cannulation group was group 2 (n=30). The groups were compared in terms of perioperative and postoperative results. Results: There was no statistically significant difference in terms of preoperative data. In terms of postoperative parameters, especially early mortality and new-onset cerebrovascular event, there was no statistically significant difference. Mortality rates in group 1 and group 2 were 13.6% (n=3) and 10% (n=3), respectively (P=0.685). Postoperative new-onset cerebral events ratio was found in 5 (22.7%) in the femoral cannulation group and 6 (20%) in the axillary cannulation group (P=0.812). Conclusion: Both femoral and axillary arterial cannulation methods can be safely performed in patients with acute type A aortic dissection, provided that cerebral protection strategies should be considered in the first place. The method to be performed may vary depending on the patient's current medical condition or the surgeon's preference.

ABSTRACT

To evaluate the early and mid-term results after surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with DeBakey typeⅠor Ⅲ aortic dissection. The clinical data of 130 patients who underwent TAAA repair for chronic DeBakey typeⅠ(groupⅠ, =47)or type Ⅲ(group Ⅲ, =83)aortic dissections in our center between January 2009 and December 2017 were retrospectively analyzed.Early postoperative results,midterm survival,and re-interventions were compared between these two groups. The 30-day mortality rate was 6.9%(=9)in the overall cohort,with no statistic difference between groupⅠand group Ⅲ(10.6% 4.8%;=0.803, =0.370).The incidence of major adverse events(38.3% 51.8%;=2.199, =0.138),5-year actuarial survival rate [(81.7±5.9)% (87.2±4.2)%;=0.483, =0.487],and 5-year actuarial freedom from all reinterventions [(84.5±6.7)% (85.5±4.8)%;=0.010, =0.920] showed no significant differences between these two groups. The early and mid-term outcomes after surgical repair of TAAA are similar for DeBakey typeⅠ and type Ⅲ patients.However,studies with larger sample sizes are still required.

ABSTRACT

To access the efficacy of stents for spontaneous isolated dissection of the superior mesenteric artery (SIDSMA). The study is a prospective single-arm study which has been registered on Clinical Trials (NCT03916965). Clinical data and follow-up information of the SIDSMA patients who received stent implantation in the First Affiliated Hospital of Zhejiang University during April 1, 2019 and September 30, 2019 were collected. The patients were recommended to be followed up at 1, 3, 6 and 12 months. A total of 34 patients were enrolled. Their mean age was (54±8) years. Abdominal pain was the most common symptom. Patients received (2.1±0.6) stents on the average. Post-operation hospital stay was (2.7±1.6) days, and the patients were followed up for (2.3±1.9) months (CT angiography) and (5.5±1.7) months (clinical visit/phone call). There was no recurrence of abdominal pain. The CT angiography showed complete remodeling and incomplete remodeling took place in 23 and 9 patients (69.7% and 27.3%), respectively. Two patients (6.1%) had mild in-stent stenosis. No stent rupture or migration was reported. This study demonstrated a satisfactory short-term result of stents implantation for SIDSMA, which indicated the endovascular treatment could be the first-line therapy for SIDSMA.
