ABSTRACT

OBJECTIVES: Thoracic aortic aneurysms (TAAs) represent one-third of the hospitalizations for aortic diseases. The prevalence rate depends on the definition of the normal size of the aorta, which is quite variable, depending on the population studied. The aim of this study was to evaluate the characteristics of the thoracic aorta of Brazilian smokers, identifying the normal size of the aorta, presence of anatomical variations, and prevalence of TAA. MATERIALS AND METHODS: A total of 711 patients underwent radiological evaluation with low-dose computed tomography (CT) from January 2013 to July 2014 with the initial objective of lung nodule tracking. Two examiners evaluated these images, and measurements of maximum and serial diameters were performed manually in true orthogonal planes. Serial diameter measurements were taken every 2 cm in the ascending aorta and 5 cm in the descending segment. We searched for anatomical variations, aortic arch type, and correlations between anatomical characteristics, sex, body mass index, and body surface area (BSA). RESULTS: The maximum diameters were 33.61 (standard deviation [SD] 3.88), 28.66 (SD 2.89), and 28.36 mm (SD 3.09) for the ascending segment, aortic arch, and descending segment, respectively. A positive correlation was found between male sex, age, and BSA and aorta diameter. The bovine arch was the most common variation of the aortic arch type, and we found one (0.14%) case of TAA. CONCLUSIONS: This study with low-dose CT allowed the determination of the mean diameters of the ascending aorta, aortic arch, and descending aorta in Brazilian smokers and TAA prevalence.

ABSTRACT

El pseudoaneurisma se define como un hematoma pulsátil repermeabilizado, encapsulado y en comunicación con la luz de un vaso dañado. Se origina cuando hay una disrupción de la pared arterial. La hemoptisis es un signo/síntoma de presentación muy rara de aneurisma aórtico torácico y de pseudoaneurisma aórtico torácico. Hay poca información sobre la hemoptisis asociada con la ruptura del aneurisma aórtico cuyo mecanismo no se explica por la presencia de una fístula aortopulmonar. Entre las hipótesis para explicar este fenómeno, se encuentra la capacidad de las arterias bronquiales de volverse hiperplásicas y tortuosas en presencia de una lesión que modifica la arquitectura pulmonar, siendo más susceptibles a la ruptura. También hay descripciones de lesiones directas del parénquima pulmonar por aneurisma roto. El presente caso nos ilustra que debemos considerar a la hemoptisis como signo de alarma en el diagnóstico diferencial de los aneurismas y pseudoaneurismas aórticos entre otras causas que puede ser fatal en breve tiempo por una hemorragia masiva.


Pseudoaneurysm is defined as a reperfused pulsatile hematoma, encapsulated and communicated with the damaged vessel's lumen. It originates when there is a disruption of the arterial wall. Hemoptysis is a very rare sign/symptom of a thoracic aortic aneurysm or pseudoaneurysm. There is little information on hemoptysis associated with aortic aneurysm rupture, whose mechanisms are not explained by the presence of an aortopulmonary fistula. Among the hypotheses to explain this phenomenon, is the ability of the bronchial arteries to become hyperplasic and tortuous in the presence of a lesion that modifies the pulmonary architecture, being more susceptible to rupture. There are also descriptions of direct lung parenchymal injury from ruptured aneurysm. The present case illustrates that we must consider the hemoptysis as a warning sign in differential diagnosis of aortic aneurysms and pseudo aneurysms, among other causes, that it can be fatal in a short time due to massive hemorrhage.

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

Abstract Chylous ascites is the pathologic accumulation of chylous fluid in the peritoneal cavity, caused by lymphomas, metastatic malignancies, and abdominal surgeries, rarely due to surgical trauma of the cisterna chyli or its major branches. A 24-year-old man with history of Marfan syndrome presented to our hospital with abdominal distention, abdominal pain, fluid in the incision region, and weakness. He had underwent an elective open aneurysm repair surgery nine days before for thoracoabdominal aortic aneurysm. Computed tomography revealed massive fluid collection in the abdominal cavity, which was drained surgically. He was diagnosed with chylous ascites and was discharged after conservative treatment.

ABSTRACT

Abstract Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have high mortality and morbidity rates, to hybrid methods. A case of a 68-year-old male patient with complex aortic arch anomaly treated with hybrid arch repair is reported in this study. Aortic branches were common carotid trunk and aberrant right subclavian artery with a saccular aneurysm.

ABSTRACT

Abstract Objective: To evaluate the aortic wall elasticity using the maximal rate of systolic distension (MRSD) and maximal rate of diastolic recoil (MRDR) and their correlation with the aortic size index (ASI). Methods: Forty-eight patients with thoracic aortic aneurysm were enrolled in this study. A standard magnetic resonance imaging (MRI) protocol was used to calculate MRSD and MRDR. Both MRSD and MRDR were expressed as percentile of maximal area/10-3 sec. ASI (maximal aortic diameter/body surface area) was calculated. A correlation between MRSD, MRDR, ASI, and the patient's age was performed using regression plot. Results: A significant correlation between MRSD (t=-4,36; r2=0.29; P≤0.0001), MRDR (t=3.92; r2=0.25; P=0.0003), and ASI (25±4.33 mm/m2; range 15,48-35,14 mm/m2) is observed. As ASI increases, aortic MRSD and MRDR decrease. Such inverse correlation between MRSD, MRDR, and ASI indicates increased stiffness of the ascending aorta. A significant correlation between the patient's age and the decrease in MRSD and MRDR is observed. Conclusion: MRSD and MRDR are significantly correlated with ASI and the patient's age. They seem to describe properly the increasing stiffness of aortas. These two new indexes provide a promising, accessible, and reproducible approach to evaluate the biomechanical property of the aorta.

ABSTRACT

Resumen: El compromiso simultáneo del arco aórtico y aorta descendente proximal, ya sea por disección o aterosclerosis, constituye uno de los mayores desafíos que puede enfrentar un cirujano cardiovascular. La prótesis híbrida Thoraflex, introducida en los últimos años, ha resultado ser una importante ayuda para el tratamiento quirúrgico de esta compleja y grave patología. Esta consiste en un tubo protésico de Dacron con 4 ramas, para el reemplazo del arco aórtico y sus troncos braquiocefálicos y perfusión corporal distal, y una endoprótesis que queda como "trompa de elefante suspendida" en la aorta descendente proximal. Presentamos en esta oportunidad nuestra experiencia inicial en 4 pacientes, 3 con disección aórtica crónica y una con un aneurisma aterosclerótico, usando la prótesis híbrida Thoraflex.


Abstract: Atherosclerotic aneurysm or dissection of the aortic arch and proximal descending thoracic aorta is one of the major challenges for a cardiovascular surgeon. The new hybrid prosthesis Thoraflex has become an important devise to simplify the surgical treatment of this very complex and technically demanding aortic pathology. This hybrid prosthesis consists of a 4-branched arch graft with a stent-graft at the distal end. The proximal part is a gelatin-coated woven polyester prosthesis. The stented section is a self-expanding endoprosthesis constructed of thin-walled polyester and nitinol ring stents that is left in the proximal descending aorta as a "frozen elephant trunk". We present our initial experience with the Thoraflex prosthesis in four patients, three of them with chronic aortic dissection and one with an atherosclerotic aneurysm.

ABSTRACT

The mortality of patients with mycotic aneurysms is high, especially in East Asia, and infection by Salmonella species is the most common. Our study aimed to improve prognosis of adult mycotic aneurysms with early diagnosis and accurate treatment. Four adult patients with mycotic aneurysm caused by Salmonella were included and analyzed by single-center retrospective analysis. Cases reported in the literature during the past 10 years were also summarized. The average age of the 4 male patients was 61.25 years, while that of the 53 cases reported in the literature was 65.13 years. Hypertension, diabetes, and atherosclerosis were common complications. Most patients presented fever and experienced pain at the corresponding position of the aneurysm. Laboratory examination found an increased number of white blood cells accompanied by an increase in inflammatory markers. Most aneurysms were found in the abdominal aorta, while the rupture of an aneurysm was the most common complication. The mortality rates were 21.43 and 7.14% after open surgery or endovascular aneurysm repair (EVAR) intervention, respectively. The recurrence rates of infection were 0 and 17.85% for both treatments, respectively. The mortality rate of mycotic aneurysm caused by Salmonella infection was high in middle-aged males with hypertension, diabetes, and atherosclerosis. The possibility of a Salmonella-infected aneurysm should be considered in these high-risk groups presenting chills, fever, chest, and back pain. Open surgery was superior to EVAR treatment in the clearance of infected foci and the reduction of postoperative recurrence. The recurrence of postoperative infection can be prevented by intravenous antibiotic therapy for 6 weeks post-surgery.

ABSTRACT

Abstract: The aorta can be affected by a variety of pathologic processes leading to aneurysm, dissection, or ischemic syndromes. The term aneurysm referring to dilatation, the criterion for definition is controversial. An aneurysm is defined as a 50% enlargement of the normal aorta for a particular body surface area, age, and gender. Another proposed definition depends on the affected segment having a diameter more than 1.5 to 2.0 times normal and represents a pathologically dilated segment of the aorta that has the propensity to expand and rupture. The maximum diameter of the thoracic aorta should not exceed 40 mm. The aorta is a geometrically complex and dynamic evaluation structure is not simple. The aortic aneurysms are associated with degenerative changes, congenital anomalies, inflammatory, micotic, traumatic, or post-stenotic process. The majority of ascending aortic aneurysms are detected as incidental. Echocardiography is the most useful tool for diagnostic evaluation, etiology, progression, risk of rupture, need for intervention and response to treatment of thoracic aneurysms. The predicted aortic root diameter or PARD, the diameter ratio, area height ratio, expansion rate and Z-score; improve the detection and limit the error rates so we must apply them routinely in the echocardiographic examination of patients with suspected or diagnosed aortic aneurysm. Echocardiographic evaluation of the aorta should not be limited to simply measuring the diameter.(AU)


Resumen: La aorta puede afectarse por una variedad de procesos patológicos que conducen al desarrollo de aneurismas, disección o de síndromes isquémicos. El término aneurisma hace referencia a una dilatación, el criterio de definición es polémico. Un aneurisma se establece como un incremento del 50% de las dimensiones normales aórticas para una determinada superficie corporal, edad y género. Otra definición propuesta depende de que el segmento afectado tenga un diámetro de 1.5 a 2.0 veces por encima del normal y representa un segmento aórtico con dilatación patológica que tiene la propensión a la expansión y a la ruptura. El diámetro máximo de la aorta torácica no debe superar los 40.0 mm. La aorta es una estructura geométricamente compleja y dinámica cuya evaluación no es simple. Los aneurismas aórticos están asociados con cambios degenerativos, anomalías congénitas, procesos inflamatorios, micóticos, traumáticos o postestenóticos. La mayoría de los aneurismas de la aorta ascendente se detectan de manera incidental. La ecocardiografía es la herramienta más útil para la evaluación diagnóstica, etiológica, de progresión, del riesgo de ruptura, intervención y en la respuesta al tratamiento de los aneurismas torácicos. El diámetro de la raíz aórtica predicho o DRAP, la relación del diámetro, la proporción de altura-área, la tasa de expansión y el score-Z, mejoran la detección y delimitan la tasa de error por lo que su aplicación debe ser rutinaria en la ecocardiografía transtorácica de aquellos pacientes con sospecha o diagnóstico de aneurisma aórtico. La evaluación ecocardiográfica de la aorta no se debe limitar a la simple medición del diámetro.(AU)

ABSTRACT

Abstract Introduction: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques - open debranching of the arch and endovascular approach of the descending aorta - may extend a less invasive endovascular treatment for a more extensive disease with necessity of proximal landing zone in the arch. Objective: To evaluate descending thoracic aortic remodeling by means of volumetric analysis after hybrid approach of aortic arch debranching and stenting the descending aorta. Methods: Retrospective review of seven consecutive patients treated between September 2014 and August 2016 for diseases of proximal descending aorta (aneurysms and dissections) by hybrid approach to deliver the endograft at zone 1. Computed tomography angiography were analyzed using a specific software to calculate descending thoracic aorta volumes pre- and postoperatively. Results: Follow-up was done in 100% of patients with a median time of 321 days (range, 41-625 days). No deaths or permanent neurological complications were observed. There were no endoleaks or stent migrations. Freedom from reintervention was 100% at 300 days and 66% at 600 days. Median volume reduction was of 45.5 cm3, representing a median volume shrinkage by 9.3%. Conclusion: Hybrid approach of arch and descending thoracic aorta diseases is feasible and leads to a favorable aortic remodeling with significant volume reduction.

ABSTRACT

Abstract Advent of antiretroviral therapy has increased survival of patients with human immunodeficiency virus (HIV) infections, with the result that some of these patients now develop degenerative diseases, such as atherosclerotic aneurysms. Degenerative thoracoabdominal aortic aneurysm is rare in HIV patients. In this report, a 63-year-old male patient with HIV submitted to open repair of thoracoabdominal aortic aneurysm. The patient did not suffer any type of complication in the perioperative period and remained well in a 28-month follow-up period. In summary, open repair still remains a good alternative for aortic complex aneurysms even in HIV patients.

ABSTRACT

Abstract A ruptured descending thoracic aortic aneurysm (rDTAA) is a life-threatening condition associated with high morbidity and mortality. Endovascular treatment for rDTAA promotes effective aneurysm exclusion with a minimally invasive approach. The authors report a case of a 76-year-old man with hemodynamically unstable 9-cm-diameter rDTAA treated with emergency thoracic endovascular aortic repair (TEVAR).

ABSTRACT

A 62-year-old man was admitted, and thoracic endovascular aortic repair (TEVAR) procedure was performed to treat an accidentally detected aortic aneurysm, which was 63 mm in diameter. While performing TEVAR, the passage of the stent-graft introducer system was impossible due to the prolapse of the introducer system into a wide-necked aneurysm; this aneurysm was located at the greater curvature of the proximal descending thoracic aorta. In order to advance the introducer system, a compliant balloon was inflated. Thus, we created an artificial wall in the aneurysm with this inflated balloon. Finally, we were able to advance the introducer system into the target zone.

ABSTRACT

Penetrating atheromatous ulcer is the condition in which ulceration of an aortic atherosclerotic lesion penetrates the internal elastic lamina into the media. Differentiation of penetrating atheromatous ulcer from other causes of acute aortic syndrome such as intramural haematoma and aortic dissection is difficult. The main symptom is a severe, acute chest pain radiating to the inter-scapular area, similar to classical acute aortic dissection of the thoracic aorta. In present article a case of a 52 years old woman with long- standing retrosternal chest pain and with penetrating atherosclerotic aortic ulcer in descending aorta was reported. Unlike the predominant picture of this disease, associated intramural hematoma was not seen

ABSTRACT

A 42-year-old man was involved in a motor vehicle collision. Imaging studies revealed the presence of a post-traumatic aortic pseudo-aneurysm (about 34x26 cm) arising from the descending thoracic aorta at the level of the left subclavian artery (LSA), prone to rupture. Thoracic endovascular aneurysm repair (TEVAR) was the only feasible option due to his poor overall medical status. In this case, LSA needed to be covered in order to extend the proximal landing zone. Eventually, modified TEVAR was successfully performed by means of the chimney technique to preserve flow to the LSA and to prevent flow into the pseudoaneurysmal sac.

ABSTRACT

A right-sided aortic arch (RAA) is a rare congenital anomaly, and Stanford type B dissection aneurysms involving this anomaly is also uncommon. Surgical approaches to dealing with an RAA are complicated by the unusual anatomical features of the condition. Here we report the case of a 47-year-old male who had a type B dissecting aneurysm involving an RAA with Kommerell's diverticulum. Graft replacement was successfully performed with an uneventful postoperative course.
