RESUMO

OBJECTIVE: To report our own experience of hybrid treatment using FET technique in patients with type A aortic dissection and concomitant lesion of aortic arch and ascending aorta. MATERIAL AND METHODS: There were 90 (28,3%) FET procedures for the period from January 2010 to August 2019. Type B aortic dissection was diagnosed in 19 (45,2%) patients. Type B aortic dissection combined with aortic arch aneurysm occurred in 11 (58%) cases, ascending aorta aneurysm - 15 (79%) cases. Patients underwent total arch and ascending aorta replacement via median sternotomy (upper partial J-shaped sternotomy in 3 cases). Valve-sparing interventions were performed in 58% of cases (aortic root repair - 6 (32%) patients, David procedure - 5 (26%) cases). Intraoperative features, early postoperative morbidity and in-hospital mortality were retrospectively analyzed. In long-term period, distal aortic remodeling, survival rate and incidence of redo interventions were evaluated. RESULTS: Mean CPB time was 166±27 min, aortic cross-clamping time - 93±23 min, duration of circulatory arrest - 43±11 min. Neurological complications and paraplegia were absent. In-hospital mortality was absent. Reversible acute renal failure without need for hemodialysis developed in 2 cases (11%). Two patients underwent repeated intervention (TEVAR) due to dSINE and negative aortic remodeling. Annual survival rate was 100%. Freedom from redo aortic surgery was 89,5%. CONCLUSION: FET surgery is an adequate alternative treatment for type B aortic dissection combined with lesion of aortic arch and ascending aorta. This approach ensures a one-stage repair in patients with contraindications to TEVAR. Unlike thoracotomy, FET procedure is valuable for simultaneous correction of cardiac and proximal aortic lesion, stabilizing the distal segments of dissected aorta. This is obvious advantage of this technique.

RESUMO

BACKGROUND: Aortoesophageal fistula (AEF) caused by an esophageal foreign body is a life-threatening crisis, with rapid progress and high mortality. The first case of AEF was reported in 1818, but the first successfully managed case was not until 1980. Although there have been some reports on this condition, in most cases, the aorta was invaded and corroded due to its adjacent relationship with the esophagus and subsequent mediastinitis. To date, few reports have described an aortic wall directly penetrated by a sharp foreign body, likely because this type of injury is extremely rare and most patients cannot receive timely treatment. Here, we present a rare case of a fish bone that directly pierced the aorta via the esophagus. CASE PRESENTATION: A 31-year-old female experienced poststernum swallowing pain after eating a meal of fish. Gastroscope showed a fishbone-like foreign body had penetrated the esophagus wall. Computed tomography revealed that the foreign body had directly pierced the aorta to form an AEF. Surgery was successfully performed to repair the aorta and esophagus. The postoperation and follow-up was uneventful. CONCLUSIONS: For the treatment of foreign bodies in the esophagus, we should be alert of the possibility of AEFs. The effective management of AEFs requires early diagnosis and intervention, as well as long-term treatment and follow-up, which still has a long way to go.

RESUMO

RATIONALE: Pulmonary sequestration (PS) presenting with elevated serum tumor markers is rare, and it might be misdiagnosed as malignancy. PATIENT CONCERNS: A 26-year-old asymptomatic male patient was admitted because the x-ray showed an intrathoracic lesion. Meanwhile, the serum neuron-specific enolase (NSE) was elevated. Three-dimensional computed tomography angiography revealed an isolated feeding vessel arising from the aorta. DIAGNOSES: Extralobular PS was confirmed by computed tomography angiography and postoperative pathological staining. INTERVENTIONS: Two-port thoracoscopic resection of the sequestrated lobe was performed. OUTCOMES: The serum NSE decreased to within the normal range and persisted during the follow up of 10 months. LESSONS: A thorough work-up should be considered for the PS patients presenting with abnormal serum NSE. Detailed knowledge regarding the relationship between NSE and PS necessitates further studies.

RESUMO

Embologenic arterial obstruction remains an extremely important problem of modern medicine. Emboli may affect virtually all arterial vessels of the greater circulation and in some cases arterial emboli may be multiple. The purpose of the present study was to work out a classification of multiple arterial emboli. Analysing the clinical material including over 30 years a total of 1804 patients with embolism of the aorta and major arteries of the limbs made it possible to define the range of the terms used and to submit for discussion a classification describing a situation where emboli affect simultaneously several arteries or occur repeatedly. Both cases involve several emboli migrating from the primary source into the arterial bed, therefore we suggest that all these emboli be called multiple. Simultaneous multiple emboli were classified as combined, multifocal, and layered, with repeated emboli classified as preceding, recurrent, early and remote. Simultaneous emboli were observed in 91 (5%) patients, of these, in 22 - combined, in 49 - multifocal, in 19 - layered, and in 1 case - combined and multifocal. Repeated emboli were revealed at various terms and encountered virtually in each third patient. Overall mortality amongst the patients with embolism of the aorta and arteries of the limbs over 30 years amounted to 13%, having over the last decade decreased to 7.6%. Multiple arterial emboli significantly influenced the outcomes of treatment, with the mortality rate in combined emboli increasing virtually to 50% and that in multifocal and layered emboli exceeding 20% (p<0.05). Early recurrent emboli in the postoperative period were observed in 6.8% of patients, significantly deteriorating the prognosis (mortality - 49.2%). In the remote period, 22.4% of the patients were operated on for recurrent embolism of arteries of the extremities, with more than 25% of the patients having experienced emboli of cerebral or visceral arteries. Recurrent thromboembolic complications played a significant role in the thanatogenesis in each 4th patient.

RESUMO

A surgical intervention for type A acute aortic dissection is the only effective method of treatment making it possible to prevent the development of life-threatening complications and to attain clinical recovery of the patient. Supracoronary replacement of the ascending aorta and the proximal portion of the aortic arch is considered to be the classical and most commonly used method of an open operative intervention. On the one hand, it is technically the simplest and shortest operation, and on the other, this surgical technique is often accompanied by long-term proximal and distal complications, and first of all those caused by a persistent false lumen. The accumulated surgical experience and contemporary operative techniques, as well as advances of intensive therapy in treatment of type A acute aortic dissection make it possible to currently perform more extensive primary resections in order to improve the remote results. Total aortic arch replacement, including the use of the 'frozen elephant trunk' technique leads to fast thrombosis of the false lumen, preventing progression of the disease of the thoracic aorta and promoting its positive remodelling. The article describes the perioperative therapeutic policy accepted and pursued in our medical facility, also presenting the authors' opinion on the role and place of the 'frozen elephant trunk' technique in rendering medical care for patients with type A acute aortic dissection.

RESUMO

The article deals with the results of successful surgical management of a male patient with a ruptured thoracic aortic aneurysm, posing particular problems as to deciding upon the scope and stages of surgical reconstruction, accompanied by describing the dynamics of clinical and diagnostic parameters, as well as the main events of the postoperative period. This clinical case report was characterized by additional difficulties due to the occurrence of subtotal haemothorax. Also presented herein is a set of comprehensive measures making it possible to successfully complete open reconstruction of the thoracic portion of the aorta and to achieve a satisfactory outcome both during the in-hospital period and within one-year follow up. Besides, elucidated is the state-of-the-art of this problem in the world literature.

RESUMO

Elderly and aged patients appear to have a significantly increased risk from a cardiosurgical intervention combining three-valve reconstruction and prosthetic repair of the ascending portion of the aorta. Triple-valve pathology in pronounced mitral insufficiency is often accompanied by concomitant dilatation of the left atrium, i. e., atriomegaly. With the aim to eliminate the syndrome of compression of surrounding tissues and normalize intracardiac haemodynamics, reduction of the left atrium should become an inherent procedure for atriomegaly in patients with multiple-valve pathology.

RESUMO

Described herein is a clinical case report regarding surgical treatment of a patient presenting with a ruptured Crawford type III thoracoabdominal aortic aneurysm. The patient was subjected to prosthetic repair of the thoracoabdominal aorta by the Coselli technique, as well as reduction of the aneurysmal sac in the thoracic and abdominal portions according to the authors' technique. The operation was carried out with neither connecting the patient to a heart-lung machine nor use of pharmacological protection of the visceral organs. The sutures were removed on postoperative day 12 and the patient was discharged from hospital in a satisfactory condition.

RESUMO

Objective: To investigate the expression pattern of tropomyosin 2(TPM2) in aorta of patients with aortic dissection and explore its clinical implication. Methods: Thirteen cases with acute type A aortic dissection(TAAD) diagnosed by transabdominal aortic angiography from 2015 in Tongji Hospital were included. During the operation, the aortic wall tissues of these patients were collected. Ten patients with heart transplantation were selected as control group, and normal aortic wall tissues were taken. The hematoxylin-eosin (HE) and Verhoeff's Van Gieson (EVG) staining were performed to observe the morphological changes of aorta. The mRNA expression level of TPM2 was measured by real-time fluorescent quantitative-PCR, and the protein levels of TPM2 were detected by Western blot and immunohistochemical staining. Image The J software was used to collect the optical density values of each point on the image, obtain the integrated optical density(IOD) value, and calculate the average density(%, IOD/area of the target distribution area). Results: HE and EVG staining revealed medial degeneration and broken elastic fiber in aorta of TAAD patients. The mRNA expression levels of TPM2 were significantly upregulated in aorta of TAAD patients as compared to the control group (P<0.05), so as the TPM2 protein expression levels ((9.73±1.20)% vs. (0.11±0.04)%, P<0.05). And TPM2 was mainly expressed in cytoplasm. Conclusion: The increased expression of TPM2 in TAAD patients hints that TPM2 might be involved in the pathogenesis of aortic dissection.

RESUMO

A 65-year-old man, with a history of hypertension, presented with dizziness and emesis and was admitted to a local hospital. He was a moderate smoker, but he did not take any hormone-based medication. Magnetic resonance imaging showed scattered cerebral infarction in the bilateral cerebral hemisphere and right cerebellar hemisphere. There were no abnormal findings in Holter monitor and echography of heart, carotid artery, and leg vein and then, antiplatelet therapy was initiated. After that, both computed tomography and magnetic resonance imaging demonstrated a floating pedunculated mass in the ascending aorta measuring 10×8×14 mm. He was admitted to our hospital 15 days after the symptom onset. Laboratory tests including immunological and coagulation studies were within normal. Computed tomography showed on the second day of the admission that the mass spontaneously disappeared, thus canceling the schedule of surgery. He received an oral anticoagulant and discharged uneventfully. During a follow-up period of 6 months, there is no recurrence of the thrombus in the aorta and thromboembolic events.

RESUMO

BACKGROUND: Cardiovascular magnetic resonance (CMR) phase contrast (PC) flow measurements suffer from phase offset errors. Background subtraction based on stationary phantom measurements can most reliably be used to overcome this inaccuracy. Stationary tissue correction is an alternative and does not require additional phantom scanning. The aim of this study was 1) to compare measurements with and without stationary tissue correction to phantom corrected measurements on different GE Healthcare CMR scanners using different software packages and 2) to evaluate the clinical implications of these methods. METHODS: CMR PC imaging of both the aortic and pulmonary artery flow was performed in patients on three different 1.5 T CMR scanners (GE Healthcare) using identical scan parameters. Uncorrected, first, second and third order stationary tissue corrected flow measurement were compared to phantom corrected flow measurements, our reference method, using Medis QFlow, Circle cvi42 and MASS software. The optimal (optimized) stationary tissue order was determined per scanner and software program. Velocity offsets, net flow, clinically significant difference (deviation > 10% net flow), and regurgitation severity were assessed. RESULTS: Data from 175 patients (28 (17-38) years) were included, of which 84% had congenital heart disease. First, second and third order and optimized stationary tissue correction did not improve the velocity offsets and net flow measurements. Uncorrected measurements resulted in the least clinically significant differences in net flow compared to phantom corrected data. Optimized stationary tissue correction per scanner and software program resulted in net flow differences (> 10%) in 19% (MASS) and 30% (Circle cvi42) of all measurements compared to 18% (MASS) and 23% (Circle cvi42) with no correction. Compared to phantom correction, regurgitation reclassification was the least common using uncorrected data. One CMR scanner performed worse and significant net flow differences of > 10% were present both with and without stationary tissue correction in more than 30% of all measurements. CONCLUSION: Phase offset errors had a significant impact on net flow quantification, regurgitation assessment and varied greatly between CMR scanners. Background phase correction using stationary tissue correction worsened accuracy compared to no correction on three GE Healthcare CMR scanners. Therefore, careful assessment of phase offset errors at each individual scanner is essential to determine whether routine use of phantom correction is necessary. TRIAL REGISTRATION: Observational Study.

RESUMO

Evaluating and treating traumatic cardiac arrest remains a challenge to the emergency medicine provider. Guidelines have established criteria for patients who can benefit from treatment and resuscitation versus those who will likely not survive. Patient factors that predict survival are penetrating injury, signs of life with emergency medical services or on arrival to the Emergency Department, short length of prehospital cardiopulmonary resuscitation, cardiac motion on ultrasound, pediatric patients, and those with reversible causes including pericardial tamponade and tension pneumothorax. Newer technologies such as resuscitative endovascular balloon occlusion of the aorta, selective aortic arch perfusion, and extracorporeal membrane oxygenation may improve outcomes, but remain primarily investigational.

RESUMO

To analyze the relationship between aortic measures and biometric parameters in a large cohort of consecutive patients undergoing computed tomography coronary angiography.1170 patients (717 men/453 women) performing computed tomography coronary angiography for coronary evaluation were retrospectively evaluated. Aortic diameters and areas were measured at reproducible anatomic landmarks, perpendicular to the axis of vessel, at the level of the aortic root (AoR), the sinotubular junction (STJ), and the tubular ascending aorta (TAo). Biometric parameters and cardiovascular risk factors were recorded.The average values of AoR, STJ, and TAo were 35.63 ±â€Š5.00 mm, 30.56 ±â€Š4.82 mm, 35.07 ±â€Š5.84 mm. Hypertension was significantly associated with aortic dimensions.Aortic measures were significantly different between men and women (37.56 ±â€Š4.77 mm vs 32.58 ±â€Š3.68 mm for AoR, 31.88 ±â€Š4.84 mm vs 28.47 ±â€Š3.98 mm for STJ and 35.93 ±â€Š5.86 mm vs 33.70 ±â€Š5.54 mm for TAo) (P < .001) and linearly increased with age. Low Spearman correlation coefficients were found and the correlation of TAo diameters with age displayed the highest values (ρ = 0.372 for male and ρ = 0.373 for female, P < .001). Multiple linear regression analysis models were compared by R. The best model used body surface area (BSA) and age as independent variables and TAo diameter as dependent variable (R = 0.29 for AoR; R = 0.21 for STJ, and R = 0.20 for TAo).In conclusion, in our population low correlation between aortic dimensions and biometric parameters highlights the difficulty of identifying normal ranges, as well as issues related to normalization using conventional biometric parameters.

RESUMO

OBJECTIVE: To compare various approaches to revascularization of aortoiliac-femoral segment. MATERIAL AND METHODS: Data were collected prospectively for retrospective analysis. There were 192 patients with atherosclerotic lesion of the aortoiliac-femoral segment who underwent reconstructive surgeries. All patients were divided into 3 groups depending on the type of reconstruction: 85 patients underwent open surgical interventions, 63 patients - endovascular interventions, 44 patients - hybrid techniques. Between-group differences were considered significant at p-value <0.05. RESULTS: Hybrid revascularization is characterized by less duration of surgery, blood loss and morbidity. Hybrid interventions ensured favorable primary patency compared to open surgery within the follow-up period. CONCLUSION: Hybrid revascularization of aortoiliac-femoral segment is characterized by less duration of surgery, blood loss and morbidity.

RESUMO

The aim of this meta-analysis was to compare the clinical outcomes in patients who underwent rapid deployment aortic valve replacement (RDAVR) and conventional bio prosthetic aortic valve replacement (CAVR).We performed a literature search by August 2018. The primary outcomes were hospital and 1-year mortality, and the secondary endpoints included the aortic cross-clamp (ACC), cardiopulmonary bypass (CPB) time, and postoperative and valve-related complications.Two randomized controlled trials and 13 propensity score-matched studies were included. There was no difference between RDAVR and CAVR in hospital mortality (2.5% versus 2.1%; risk ratio (RR) 1.16 [95% confidence interval (CI) 0.80-1.68]) or 1-year mortality (2.9% versus 4.1%; RR 0.69 [95% CI 0.34-1.34]). RDAVR significantly reduced the ACC time ( (mean difference (MD) -24.33 [95% CI -28.35 to -20.32]) and CPB time (MD -21.51 [95% CI -22.83 to -20.20]). The pooled analysis showed that RDAVR doubled the occurrence of permanent pacemaker implantation (8.6% versus 4.3%; RR 2.05 [95% CI 1.62-2.60]). Meanwhile, the blood transfusion amount (MD -1.54 [95% CI -2.22 to -0.86]) and postoperative atrial fibrillation (POAF) occurrence (RR 0.83 [95% CI 0.69-0.99]) was reduced. The difference of paravalvular leakage frequency between RDAVR and CAVR was marginal (RR 1.77 [95% CI 1.00-3.17]; P = 0.05). Furthermore, RDAVR was related to larger valves (MD 0.70 cm [95% CI 0.33-1.07]) and lower mean pressure gradients (MD -1.93 mmHg [95% CI -3.58 to -0.28]).The hospital and 1-year survival rates between RDAVR and CAVR are comparable. RDAVR reduces POAF occurrence and blood transfusion but is associated with a higher occurrence of pacemaker implantation.

RESUMO

OBJECTIVES: It remains unclear when sudden cardiac event risk outweighs surgical risk for patients with anomalous aortic origin of a coronary artery. The Congenital Heart Surgeons' Society sought to characterize the surgical risks by determining the techniques, complications, and outcomes of repair. METHODS: Between January 2000 and September 2018, 682 patients with anomalous aortic origin of a coronary artery aged 30 years or less were enrolled. Demographic, morphologic, operative, imaging, and ischemia-related data were analyzed. RESULTS: There were 395 of 682 (57%) surgical patients (45 centers, median follow-up 2.8 years). In addition to primary repair (87% unroofing, 26% commissural manipulation), 13 patients had 15 coronary-related reoperations. Of 358 patients with pre/postoperative aortic insufficiency assessment, 27 (8%) developed new mild or greater aortic insufficiency postoperatively, and 7 (2%) developed new moderate or greater aortic insufficiency. Freedom from mild aortic insufficiency differed in those with versus without commissural manipulation (85%/91% at 6 months, 83%/90% at 1 year, and 77%/88% at 3 years, respectively) (P = .05). Of 347 patients with preoperative/postoperative ejection fraction, 6 (2%) developed new abnormal ejection fraction (<50%) within 30 days of surgery which persisted. Although 64 of 395 patients (16%) had preoperative ischemia, after surgery 51 of 64 patients (80%) no longer had ischemia (13 = new postoperative ischemia, P < .0001). Four patients died postoperatively (preoperatively 2 asymptomatic, 1 symptomatic, 1 in extremis). Composite surgical adverse event rates were 7% to 13% in the entire cohort (increasing/decreasing by presentation/anatomy/repair strategy). CONCLUSIONS: Anomalous aortic origin of a coronary artery surgery may relieve ischemia with low mortality; however, it can result in a variety of important morbidities, varying by the group evaluated. Strategies avoiding commissural manipulation may decrease the risk of developing aortic insufficiency. Understanding these risks should inform surgical decision-making and support the need for standardized assessment and management.

RESUMO

Objective: Turner syndrome (TS) is a rare disorder affecting 1/2500 female newborn. Aortic dilatation (AD) and aortic dissection represent a major concern in TS. The aims of our study were to describe the aortic root growth, potential aortic dilatation (AD) risk factors and cardiovascular outcomes in a cohort of patients with TS. Methods: Among 204 adult patients included, 197 were studied using a standardized 1.5 Tesla MRI protocol. AD was defined as an aortic diameter ≥20 mm/m2 at the Valsalva sinuses and/or at the ascending aorta, when indexed to body surface area. Results: At baseline, AD was present in 81/197 (41.1%) and 32/197 (16.2%) of patients, at the levels of Valsalva and ascending aorta, respectively. The aortic Valsalva diameter was larger in patients treated for thyroiditis (P < 0.001). Potential risk factors of AD were aging (P < 0.001) and the presence of bicuspid aortic valve (BAV) (P = 0.002). The hazard ratio (HR) of AD occurrence in the presence of BAV was 2.2 (95% CI: 1.33-3.71). After a median follow-up period of 5.1 years (n = 143), AD was present in 58/143 (40.6%) and 25/143 (17.5%) of patients at the levels of Valsalva and ascending aorta, respectively. The median aortic growth of the Valsalva sinuses remained stable. At the ascending aorta, it increased by 0.14 ± 0.61 mm/year. Only one aortic-related death was observed. Conclusion: AD is common in adult patients with TS. However, our results are rather reassuring, as the median aortic diameters remained stable after 5.1 years and few aortic events were observed.

RESUMO

Penetrating aortic ulcer (PAU) is ulceration of an aortic atherosclerotic plaque penetrating through the internal lamina into the media. PAU is a rare condition and occurs in 2% - 7% of acute aortic syndromes (AAS); however, the actual incidence is unknown because of asymptomatic patients. One may treat it conservatively as well as surgically. We present a case of a 54-year-old man, who was admitted to hospital due to the exaggeration of exertional chest pain and persistent headaches. During coronary angiography, the suspicion of PAU was raised. Contrast-enhanced computed tomography confirmed the diagnosis. Transesophageal echocardiography showed bicuspid aortic valve with minimal calcification, the dilated ascending aorta, large atherosclerotic plaques in the aortic arch with ulceration (thickness: 5.0 - 5.5mm, diameter: 5 - 6 mm, depth: 3 - 4 mm), without intramural hematoma. Conservative treatment was chosen with uneventful 2-year follow-up. Although surgical management is advocated for patients with PAU type A, we demonstrated that type A PAU can be successfully treated conservatively as well.
