ABSTRACT

Chronic thromboembolic pulmonary hypertension (CTEPH) is a subtype of pulmonary hypertension characterized by the obstruction of pulmonary arteries secondary to chronic thromboembolism. Pulmonary thromboendarterectomy surgery (PTE) is the main treatment for patients with CTEPH, as it removes the chronic thrombi from the pulmonary arteries. Pulmonary reperfusion syndrome is a common complication of the surgery, which involves the development of pulmonary edema in the area where blood perfusion improves after the surgery. The incidence of this syndrome varies from 8 to 91% depending on the criteria used for diagnosis, and it is one of the most serious complications of pulmonary thromboendarterectomy. In such cases, circulatory support with extracorporeal membrane oxygenation (ECMO) has become a valuable therapeutic modality. We present the case of a 60-year-old woman with a history of acute pulmonary embolism due to deep vein thrombosis of the right pelvic limb who was diagnosed later with CTEPH who was admitted for scheduled surgical treatment involving bilateral PTE. However, during the immediate postoperative period, she developed cardiogenic shock and refractory hypoxemia secondary to pulmonary reperfusion syndrome following the surgical procedure. As a result, she required veno-venous ECMO circulatory support for 6 days, leading to resolution of the pulmonary condition and clinical improvement.


La hipertensión pulmonar tromboembólica crónica (HPTEC) es un subtipo de hipertensión pulmonar caracterizada por la obstrucción de las arterias pulmonares secundaria a tromboembolias crónicas. La cirugía de tromboendarterectomía pulmonar (TEAP) es el tratamiento principal para los pacientes con HPTEC, elimina los trombos crónicos de las arterias pulmonares. El síndrome de reperfusión pulmonar es una complicación común de la cirugía, se trata del desarrollo de edema pulmonar en el área en la que la perfusión sanguínea mejora después de la cirugía. La incidencia del síndrome varía del 8 al 91% según los criterios utilizados para diagnosticarlo y es una de las complicaciones más graves de la tromboendarterectomía pulmonar. En tales casos, el soporte circulatorio con oxigenación por membrana extracorpórea (ECMO) se ha convertido en una valiosa modalidad terapéutica. Presentamos el caso de una paciente de 60 años de edad con antecedente de tromboembolia pulmonar aguda secundaria a trombosis venosa profunda de miembro pélvico derecho a quien durante el seguimiento se realizó el diagnóstico de HPTEC e ingresó de manera programada para tratamiento quirúrgico con realización de TEAP bilateral, sin embargo durante el posquirúrgico inmediato presentó choque cardiogénico e hipoxemia refractaria secundarios a síndrome de reperfusión pulmonar, por lo cual requirió soporte circulatorio con ECMO venovenosa durante seis días, con resolución del cuadro pulmonar y mejoría clínica.

ABSTRACT

Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious and debilitating disease caused by occlusion of the pulmonary arterial bed by hematic emboli and by the resulting fibrous material. Such occlusion increases vascular resistance and, consequently, the pressure in the region of the pulmonary artery, which is the definition of pulmonary hypertension. The increased load imposed on the right ventricle leads to its progressive dysfunction and, finally, to death. However, CTEPH has a highly significant feature that distinguishes it from other forms of pulmonary hypertension: the fact that it can be cured through treatment with pulmonary thromboendarterectomy. Therefore, the primary objective of the management of CTEPH should be the assessment of patient fitness for surgery at a referral center, given that not all patients are good candidates. For the patients who are not good candidates for pulmonary thromboendarterectomy, the viable therapeutic alternatives include pulmonary artery angioplasty and pharmacological treatment. In these recommendations, the pathophysiological bases for the onset of CTEPH, such as acute pulmonary embolism and the clinical condition of the patient, will be discussed, as will the diagnostic algorithm to be followed and the therapeutic alternatives currently available.

ABSTRACT

INTRODUCTION: Here we describe our technique and results of beating heart pulmonary thromboendarterectomy (PTE) with cardiopulmonary bypass (CPB) in four patients for treatment of chronic thromboembolic pulmonary hypertension (CTEPH). METHODS: Retrospective analysis of data from patients who underwent PTE for CTEPH between January 2019 and September 2020. Patients were followed up with clinical assessment, 2D echocardiography, and computed tomography pulmonary angiogram. RESULTS: Four patients were operated for CTEPH using our technique. Moderate tricuspid regurgitation (TR) and severe TR were found in two patients each. Severe right ventricular (RV) dysfunction was found in all cases. Thrombi were classified as Jamieson type II in three cases and type I in one case. Postoperative median direct manometric pulmonary artery (PA) pressures decreased (from 46.5 mmHg to 23.5 mmHg), median CPB time was 126 minutes, and median temperature was 33.35 °C. Mechanical ventilation was for a median of 19.5 hours. There was one re-exploration. Median intensive care unit stay was 7.5 days. There was no mortality. Postoperative 2D echocardiography revealed decrease in median PA systolic pressures (from 85 mmHg to 33 mmHg), improvement in RV function by tricuspid annular plane systolic excursion (median 14 mm vs. 16 mm), and improved postoperative oxygen saturations (88.5% vs. 99%). In follow-up (ranging between 2-15 months), all patients reported improvement in quality of life and were in New York Heart Association class I. CONCLUSION: With our described simple modifications, advances in perfusion, and blood conservation technologies, one can avoid the need for deep hypothermic circulatory arrest during PTE.

ABSTRACT

BACKGROUND: Pulmonary thromboendarterectomy is the current treatment of choice in patients with chronic thromboembolic pulmonary hypertension. The objective of the present study was to analyze the clinical and hemodynamic outcomes and the risk factors for mortality in a cardiovascular center in Colombia. METHODS: Cohort study, conducted between 2001 and 2019. All operated patients were included in the study. Risk factors associated with mortality were established by means of a multivariate regression using the COX method and survival was established using the Kaplan-Meier method. p < 0.05 was considered statistically significant. RESULTS: Seventy-three patients were operated. Median age was 51 years, 55% of females, 79% had functional Class III and IV. The mean pulmonary arterial pressure was 50 mmHg and 640 dyn.s.cm-5 for pulmonary vascular resistance (PVR). After the intervention, there was a decrease in mean pulmonary artery pressure (p ≤ 0.001) and in PVR (p = 0.357); 21% had evidence of residual pulmonary hypertension. Only 8% and 6% continued with functional Class III and IV at 6 and 12 months, respectively. There were 15 deaths (19.1%; 12% at 30 days). The factors associated with mortality were the diastolic diameter of the right ventricle measured postoperatively (hazard ratio [HR] 10.88 95% confidence interval [CI] 1.97-62, p = 0.007), time of invasive mechanical ventilation (HR 1.06 95% CI 1.02-1.09 p = 0.004), and the presence of complications during the surgical procedure (HR 5.62 95% CI 1.94-16.22 p = 0.001). CONCLUSIONS: Pulmonary thromboendarterectomy is associated with excellent clinical and hemodynamic outcomes. The mortality risk factors found are not those usually described in the literature.

ABSTRACT

Klinefelter syndrome  is a form of male hypogonadism due to testicular sclerohyalinosis with atrophy and azoospermia, which is the most common cause of male infertility. The syndrome is usually accompanied by metabolic, morphological, and neurobehavioral manifestations; Venous thromboembolic diseases such as deep vein thrombosis and pulmonary embolism. The existence of chronic thromboembolic pulmonary hypertension in patients with Klinefelter syndrome   is scarce in the literature. We present the imaging and genetic analysis of a 37 -year-old male with a history of deep vein thrombosis who was admitted for exertional dyspnea.

ABSTRACT

Introducción: La arteria femoral común y sus ramas suministran la mayor parte del flujo sanguíneo al muslo, así como a la totalidad de la pierna y el pie, lo que da lugar a la mayor rama del triángulo femoral: la arteria femoral profunda. Objetivo: Exponer la efectividad de la profundaplastia femoral en la "era endovascular". Reporte del caso: Se presenta un caso de enfermedad arterial periférica de múltiples sectores, sin criterio de cirugía revascularizadora (derivación protésica aorto bifemoral). El paciente manifestaba claudicación intermitente a menos de 30 metros, localizada en pantorrilla derecha. En el estudio hemodinámico se apreciaron los índices de presiones tobillo/brazo disminuidos en arteria tibial posterior (0,46) y pedia derecha (0,33). La ecografía doppler del sector femoral derecho evidenció una estenosis de la arteria femoral profunda en su origen, que producía aumento de las velocidades picos sistólicos (479 cm/s), con flujo desorganizado, dilatación posestenótica y oclusión de la arteria femoral superficial en su origen. Se realizó endarterectomía femoral común y profunda con colocación de parche de politetrafloroetileno. El paciente evolucionó sin complicaciones posoperatorias. En el seguimiento se observó mejoría clínica en relación con la distancia de claudicación y un aumento de los índices de presiones tobillo/brazo en arteria tibial posterior y pedia derecha (0,50), respectivamente. Conclusiones: La profundaplastia femoral, aún en la "era endovascular", permanece como un proceder eficaz que resulta alternativa de tratamiento revascularizador en la enfermedad arterial periférica de localización infrainguinal(AU)


Introduction: The normal femoral artery and its branches supply most of the blood flow to the thigh, as well as to the whole leg and foot, which forms the largest branch of the femoral triangle: the deep femoral artery. Objective: Show the effectiveness of femoral deep plasty in the "endovascular era". Case report: It is presented a case of peripheral artery disease in multiple sectors, without surgical criteria of revascularization (derivación protésica aortobifemoral). The patient presented intermittent claudication in less than 30 meters, and it was located in the right calf. In the hemodynamic study, the ankle-arm pressure indexes were dicreased in the posterior tibial artery (0,46) and right dorsalis pedis artery (0,33). The doppler echocardiography of the right femoral sector confirmed a stenosis in the deep femoral artery in its origin, which produced an increase in the peak systolic velocity (479 cm/s), unorganized flows, poststenotic dilatation and occlusion of the superficial femoral artery in its origin. It was performed a common and deep femoral endarterectomy with colocation of polytetrafluoroethylene patch. The patient evolved without post-surgical complications. In the follow-up, it was observed a clinical improvement in relation with the claudication distance and the increase of the ankle-arm pressure indexes in the posterior tibial artery and right dorsalis pedis artery (0,50), respectively. Conclusions: The femoral deep plasty, still in the ´´endovascular era´´, is an efficient procedure that is an alternative to the revascularization treatment in the peripheral artery disease with infrainguinal location(AU)

ABSTRACT

Heart transplantation remains the gold standard of therapy for patients with end-stage heart failure. Submassive pulmonary embolism in a patient with heart failure is generally considered a contraindication to immediate heart transplantation, given the risk of right heart failure posttransplant. Generally patients must wait for extended periods of time to recover from pulmonary embolism therapies before being listed for transplant. We report a case of successful concomitant pulmonary thromboendarterectomy and heart transplantation.

ABSTRACT

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism, characterized by non-resolving fibro-thrombotic obstructions of large pulmonary arteries. Pulmonary endarterectomy (PEA) is the treatment of choice for the disease, significantly improving survival. Patients with worse hemodynamic profile have worse prognosis after surgery, raising the question of whether the use of medical therapy prior to surgery to optimize hemodynamics could improve outcomes. The aim of this study was to evaluate the role of medical therapy pre-PEA, according to the hemodynamic profile at the diagnosis. We retrospectively analyzed all patients submitted to PEA, from January 2013 to December 2017. Functional, clinical and hemodynamic data were collected to evaluate the main prognostic determinants. Patients were stratified according to the hemodynamic severity and use of targeted therapies prior to surgery. A total of 108 patients were included. Thirty-five patients (32,4%) used targeted therapy pre-PEA. The use of medical therapy delayed the surgical procedure by about 7 months. There was no difference in overall survival between patients that received targeted therapy and those treated only with supportive therapy (87.8% vs 80.3%, respectively, p = 0.426). Nevertheless, when analyzing the group of patients with severe hemodynamic impairment, defined by low cardiac output(<3.7L/min) at baseline, patients treated with targeted therapies presented a significantly better one-year survival. In higher-risk CTEPH patients, characterized by the presence of low cardiac output, the use of targeted therapies prior to PEA was associated with better outcome, suggesting a potential role for pre-operative use of medical treatment in this particular subgroup.

ABSTRACT

Chronic thromboembolic pulmonary hypertension is characterized by the presence of organized thrombotic material in the pulmonary arteries which causes elevation of the pulmonary vascular resistance, right heart failure, and death if not treated. Pulmonary thromboendarterectomy is the treatment of choice and can be curative when the obstruction is proximal. There are cases in which this therapy is not possible, and pulmonary angioplasty is a therapeutic alternative of growing interest. We present our experience with three patients diagnosed with chronic thromboembolic pulmonary hypertension in whom pulmonary endarterectomy was not possible and pulmonary angioplasty was performed. All patients showed improvement of functional class, six-minute walk distance, and hemodynamic as well as angiographic parameters.

ABSTRACT

La hipertensión pulmonar tromboembólica crónica se caracteriza por la presencia de material trombótico organizado dentro de las arterias pulmonares que genera elevación de la resistencia vascular pulmonar, insuficiencia cardíaca derecha y, eventualmente, la muerte. El tratamiento de elección es la tromboendarterectomía pulmonar, que suele ser curativa si la obstrucción es proximal. En algunos casos este tratamiento no es posible y surge como alternativa la angioplastia pulmonar con balón (APB), que está generando creciente interés. Se presentan tres casos de pacientes con hipertensión pulmonar tromboembólica a los que por diferentes circunstancias no pudo tratarse con tromboendarterectomía y se realizó APB comprobándose, en los tres casos, mejoría de la clase funcional, prueba de la caminata de seis minutos, además de parámetros hemodinámicos y angiográficos.

ABSTRACT

OBJECTIVE: To analyse hospital mortality in patients subjected to cardiac surgery in Mexico during the year 2015, and identify the mortality risks factors, and its correlation with days of hospital stay in the cardiovascular intensive care unit. METHOD: The database of Cardiovascular Intensive Care of the National Institute of Cardiology was examined for this cases and controls study that included only adult patients subjected to cardiac surgery during the year 2015. RESULTS: A total of 571 patients were subjected to a surgical procedure. The predominant indication was single or multiple valve replacement surgery, followed by coronary revascularisation surgery, and correction of adult congenital heart disease. Overall mortality was 9.2, and 8% died in intensive care. The main risk factors for death were preoperative organ failure or pulmonary hypertension, and prolonged time with extracorporeal circulation. The primary cause of death was secondary to cardiogenic shock. The hospital mortality observed in this population was higher for patients undergoing pulmonary thromboendarterectomy, complex aortic disease surgery, and valvular surgery. CONCLUSIONS: The mortality of patients undergoing cardiac surgery in Mexico differs slightly from that reported in the world literature, primarily because there were more multivalvular surgeries and mixed complex procedures performed.

ABSTRACT

Resumen Objetivo: Analizar las causas de mortalidad hospitalaria de pacientes operados de cirugía cardiaca en México en el año 2015. Identificar los factores de riesgo de mortalidad y realizar una correlación con el tiempo de estancia hospitalaria en terapia intensiva cardiovascular. Método: Estudio de casos y controles. Se estudió la base de datos de la Terapia Intensiva Cardiovascular del Instituto Nacional de Cardiología. Se incluyeron todos los pacientes adultos operados de cirugía cardiaca en el año 2015. Resultados: Se operaron 571 pacientes. La indicación quirúrgica predominante fue la cirugía de cambio valvular único o múltiple, seguida de la cirugía de revascularización coronaria y corrección de cardiopatías congénitas del adulto. La mortalidad global fue de un 9.2% y el 8% falleció en terapia intensiva. Los principales factores de riesgo de muerte fueron la presencia de falla orgánica o hipertensión pulmonar prequirúrgica, y el tiempo prolongado de circulación extracorpórea. La principal causa de muerte fue el choque cardiogénico. La mortalidad hospitalaria observada en esta población fue mayor para los operados de tromboendarterectomía pulmonar, cirugía de enfermedad aórtica compleja y cirugía valvular. Conclusiones: La mortalidad de los pacientes operados de cirugía cardiaca en México difiere levemente de la reportada en la literatura mundial porque se trata mayormente de cirugía multivalvular y de procedimientos quirúrgicos mixtos complejos.

ABSTRACT

Objetivo: Caracterizar las variantes quirúrgicas realizadas a los pacientes ingresados con enfermedad cerebrovascular extracraneal en un período de dos años.Métodos: Estudio descriptivo prospectivo en 27 pacientes, sin distinción de edad y sexo, operados por enfermedad cerebrovascular de origen extracraneal. Se tuvieron en cuenta los criterios de cirugía, además del estadio clínico, enfermedad cerebrovascular extracraneal que motivó la operación, localización de la lesión carotidea, variantes quirúrgicas realizadas, la permeabilidad de estas y las complicaciones poscirugía. Los pacientes fueron seguidos en consulta externa por dos años.Resultados: Se encontró que el 44,4 por ciento tuvo un ataque transitorio isquémico. Fueron más frecuentes las lesiones unilaterales (85,2 por ciento) y las de la carótida derecha (48,1 por ciento). Se halló una asociación significativa entre el sexo masculino con el estadio clínico y la localización de las lesiones carotideas. La endarterectomía por eversión fue la variante quirúrgica más realizada (44,4 por ciento). El 96,3 por ciento de las intervenciones se mantuvo permeable hasta los 18 meses poscirugía, mientras que tres pacientes presentaron reestenosis a los 24 meses. El 40,7 por ciento no desarrolló complicaciones, y entre estas el sangrado fue la de mayor frecuencia (33 por ciento).Conclusiones: Las variantes quirúrgicas realizadas se caracterizaron por altos porcentajes de permeabilidad durante el tiempo de estudio, con un mínimo de complicaciones posquirúrgicas(AU)


Objective: To characterize the surgical variants performed in hospitalized patients with extracranial cerebrovascular diseases in two years.Methods: Prospective and descriptive study of 27 patients, regardless of age and sex, who had been operated on from cerebrovascular disease of extracranial origin. Surgical criteria, clinical condition, extracranial cerebrovascular disease that required surgery, location of the carotid lesion, surgical variants, their permeability and the post-surgery complications were all taken into account. The patients were followed-up in the outpatient service during two years.Results: It was found that 44.4 percent of patients had had a transient ischemic attack. Unilateral lesions (85.2 percent) and right carotid lesions (48.1 percent) were the most common. Significant association was found between the male sex and the clinical staging and the location of carotid lesions. Eversion endarterectomy was the most performed surgical technique (44.4 percent). In the study, 96.3 percent of operations were kept permeable up to 18 months after the surgery whereas three patients presented with re-stenosis after 24 months. In the study group, 40.7 percent did not develop complications, being bleeding the most frequent one (33 percent).Conclusions: The surgical variants performed in the study time were characterized by high percentages of permeability and minimal postsurgical complications(AU)

Se tuvieron en cuenta los criterios de cirugía, además del estadio clínico, enfermedad cerebrovascular extracraneal que motivó la operación, localización de la lesión carotidea, variantes quirúrgicas realizadas, la permeabilidad de estas y las complicaciones poscirugía. Los pacientes fueron seguidos en consulta externa por dos años. Resultados: Se encontró que el 44,4 por ciento tuvo un ataque transitorio isquémico. Fueron más frecuentes las lesiones unilaterales (85,2 por ciento) y las de la carótida derecha (48,1 por ciento). Se halló una asociación significativa entre el sexo masculino con el estadio clínico y la localización de las lesiones carotideas. La endarterectomía por eversión fue la variante quirúrgica más realizada (44,4 por ciento). El 96,3 por ciento de las intervenciones se mantuvo permeable hasta los 18 meses poscirugía, mientras que tres pacientes presentaron reestenosis a los 24 meses. El 40,7 por ciento no desarrolló complicaciones, y entre estas el sangrado fue la de mayor frecuencia (33 por ciento). Conclusiones: Las variantes quirúrgicas realizadas se caracterizaron por altos porcentajes de permeabilidad durante el tiempo de estudio, con un mínimo de complicaciones posquirúrgicas(AU)


Objective: To characterize the surgical variants performed in hospitalized patients with extracranial cerebrovascular diseases in two years. Methods: Prospective and descriptive study of 27 patients, regardless of age and sex, who had been operated on from cerebrovascular disease of extracranial origin. Surgical criteria, clinical condition, extracranial cerebrovascular disease that required surgery, location of the carotid lesion, surgical variants, their permeability and the post-surgery complications were all taken into account. The patients were followed-up in the outpatient service during two years. Results: It was found that 44.4 percent of patients had had a transient ischemic attack. Unilateral lesions (85.2 percent) and right carotid lesions (48.1 percent) were the most common. Significant association was found between the male sex and the clinical staging and the location of carotid lesions. Eversion endarterectomy was the most performed surgical technique (44.4 percent). In the study, 96.3 percent of operations were kept permeable up to 18 months after the surgery whereas three patients presented with re-stenosis after 24 months. In the study group, 40.7 percent did not develop complications, being bleeding the most frequent one (33 percent). Conclusions: The surgical variants performed in the study time were characterized by high percentages of permeability and minimal postsurgical complications(AU)

ABSTRACT

A doença aterosclerótica das carótidas extracranianas pode resultar em complicações com alta morbidade e mortalidade. A avaliação pré-operatória com exames contrastados de imagem é associada a complicações como a parotidite, além das já bem conhecidas reações alérgicas e da disfunção renal. A bifurcação carotídea alta e a doença aterosclerótica de extensão cranial costumam ser fatores limitantes para o tratamento cirúrgico convencional. Entretanto, quando há contraindicação ao uso de contraste iodado ou impossibilidade do tratamento endovascular, há a necessidade do conhecimento de técnicas cirúrgicas que permitam a realização da endarterectomia com segurança. A subluxação da mandíbula se mostrou uma técnica adjuvante segura e efetiva, de fácil execução e reprodutibilidade, possibilitando o acesso a bifurcações carotídeas altas com boa exposição do campo cirúrgico e permitindo a realização da endarterectomia conforme a técnica padrão. Apresentamos o caso de uma paciente com bifurcação carotídea alta e com limitações para uso do contraste iodado que foi submetida a endarterectomia carotídea após subluxação de mandíbula


Atherosclerotic disease of the extracranial carotid arteries can cause complications with high morbidity and mortality rates. The contrast imaging examinations used in preoperative evaluation are associated with complications such as parotitis, in addition to well-known allergic reactions and renal dysfunction. A high carotid bifurcation or atherosclerotic disease that extends distally are often limiting factors for conventional surgical treatment. However, when iodinated contrast is contraindicated or endovascular treatment is not feasible, knowledge of surgical techniques that allow safe endarterectomy is required. Subluxation of the mandible has proven to be a safe and effective adjuvant technique that is easy to perform and reproducible, providing access to high carotid bifurcations with good exposure of the surgical field and allowing endarterectomy to be performed with a standard technique. We present the case of a patient with a high carotid bifurcation and limitations for use of iodinated contrast who underwent carotid endarterectomy after subluxation of the mandible

ABSTRACT

La oclusión de la arteria carotidea interna no es infrecuente, típicamente su evolución impide la endarterectomía debido a que el trombo se extiende hasta el origen de la arteria oftálmica y hace inadecuada su reconstrucción. La carótida interna solo emite ramas intracraneales, pero extraordinariamente, existe una rama extracraneal de la carótida interna que mantiene el flujo distal a la oclusión y hace viable la revascularización como en el caso que se describe a continuación. Se trata de un paciente masculino, blanco, de 67 años de edad, fumador inveterado con antecedentes de dislipidemia. Acude por presentar disminución de la visión del ojo izquierdo acompañado de cuadros vertiginosos. Con el ultrasonido vascular y la angiotomografía computarizada se comprobó la oclusión de la emergencia de la carótida interna izquierda, con recanalización distal y presencia de vaso colateral anómalo. Se realizó endarterectomía carotidea y restitución del flujo a la carótida interna con preservación del vaso anómalo. El paciente evolucionó de forma satisfactoria. El conocimiento de las variantes anatómicas y una técnica cuidadosa permiten alcanzar buenos resultados en la cirugía de la oclusión carotidea(AU)


Occlusion of internal carotid artery is not uncommon; its progression frequently hinders endarterectomy because the thrombus extends into the origin of the ophthalmic artery, making the carotid artery inadequate for reconstruction. The internal carotid only emits intracranial branches, but exceptionally, there is an extracranial branch of the internal carotid that keeps the distal flow to the occlusion and makes the revascularization viable as it occurs in the case described here. This is a 67 years old Caucasian male patient, heavy smoker with a history of dyslipidemia. He went to the doctors because of decreased vision in his left eye and dizzy changes. Vascular US and angiotomography showed occlusion of left internal carotid artery, with distal recanalization and presence of collateral anomalous vessel. The treatment consisted of carotid endarterectomy and reestablishment of the flow to the left internal carotid with preservation of the anomalous collateral vessel with satisfactory recovery. The knowledge of the anatomical variations and a careful surgical technique allow reaching good results in carotid occlusion surgery(AU)

ABSTRACT

A relação entre periodontite e doenças cardiovasculares (DCV) tem sido amplamente discutida, embora os mecanismos de interação não estejam claros. Foi sugerido que pacientes com periodontite apresentam inflamação sistêmica e um pequeno aumento no risco cardiovascular. Patógenos periodontais foram encontrados em placas de ateroma, mas a influência destes microrganismos na aterosclerose ainda não é compreendida. O objetivo primário deste estudo foi delinear o perfil inflamatório sistêmico de pacientes submetidos à endarterectomia carotídea. Os objetivos secundários foram associar o perfil inflamatório dos participantes à condição periodontal e à presença de patógenos orais encontrados na cavidade oral e em placas de ateroma. Trinta e cinco pacientes submetidos à endarterectomia carotídea foram incluídos neste estudo. Antes da cirurgia vascular, um exame clínico periodontal foi realizado e foram coletadas amostras de sangue, saliva e biofilme subgengival. Durante a endarterectomia, uma amostra da placa de ateroma foi coletada. As amostras de soro foram testadas com o ensaio imunoenzimático de alta sensibilidade Multiplex para dezessete marcadores de células Th17. Amostras de saliva, biofilme subgengival e placa de ateroma foram submetidas ao PCR quantitativo para avaliação de dez patógenos periodontais. Este estudo foi capaz de detectar vários marcadores inflamatórios circulantes, o que indica a presença de inflamação sistêmica como uma característica da população...


T. forsythia foi o microrganismo mais frequentemente encontrado em amostras de ateroma (37% das amostras). Níveis de T. forsythia em amostras de ateroma foram positivamente correlacionados com os níveis séricos de IL-7, IL-6, IL-17, IL-13, IL-12p70, IFN-?, GCS-F (p<0,05) e IL-10 (p<0,01). Níveis séricos de IL-2 foram positivamente correlacionados com os concentrações salivares de P. intermedia, P. endodontalis (p<0,05) e T. denticola (p<0,01). Níveis séricos de TNF-? foram positivamente correlacionados com concentrações salivares de P. endodontalis (p<0,01). Concentrações de P. endodontalis em amostras subgengivais foram correlacionadas positivamente com IL-2 (p<0,05). A inflamação periodontal (PISA) foi positivamente correlacionada com IL-2 (p<0,05). A coexistência de patógenos periodontais comuns na cavidade oral e na placa de ateroma está associada a um estado inflamatório sistêmico, o que poderia ser relevante para a compreensão dos mecanismos que ligam periodontite com DCV...
