    El SOP es el trastorno endocrino más frecuente en mujeres jóvenes. Desde 1976 Kahn describe la relación entre el androgenismo ovárico y la resistencia a la insulina. Bergen, en 1980, establece la asociación ovarios poliquísticos, hiperandrogenismo e hiperinsulinemia, visualizando que el SOP no solo es causa de infertilidad y anovulación, sino que tiene riesgos metabólicos asociados. La explicación del SOP fue re definida por un taller de consenso en Holanda, en 2003. Esta patología se present...

    Full Text Available El SOP es el trastorno endocrino más frecuente en mujeres jóvenes. Desde 1976 Kahn describe la relación entre el androgenismo ovárico y la resistencia a la insulina. Bergen, en 1980, establece la asociación ovarios poliquísticos, hiperandrogenismo e hiperinsulinemia, visualizando que el SOP no solo es causa de infertilidad y anovulación, sino que tiene riesgos metabólicos asociados. La explicación del SOP fue re definida por un taller de consenso en Holanda, en 2003. Esta patología se presenta si existen al menos dos de los tres criterios siguientes: irregularidades menstruales, signos bioquímicos o clínicos de exceso de andrógenos y la presencia de la morfología de ovario poliquístico. Los ginecólogos frecuentemente diagnostican esta patología y por tal motivo se debe tener un conocimiento adecuado sobre sus manifestaciones clínicas y sus posibles riesgos en el largo plazo. La evidencia de la supuesta asociación con el cáncer de endometrio y predisposición a enfermedad coronaria es incompleta, pues la variedad de definiciones del SOP hace difícil su comparación. Dunaif refiere que la prevalencia de resistencia a la insulina es una función de la población estudiada y la sensibilidad y especificidad del método usado para medir este parámetro. También menciona que las mujeres con SOP son hiperinsulinémicas y resistentes a insulina, independientemente de la obesidad, comparadas con mujeres normales. Legro demostró que entre el 25 y el 30% de las mujeres con el SOP tienen intolerancia a la glucosa a los 30 años, y el 8% desarrollarán franca Diabetes Mellitus tipo 2, anualmente.Polycystic ovary syndrome is the most frequent endocrine disorder. In 1976 Kahn described the relation of ovarian hyperandrogenism and insulin resistance. Bergen in 1980 established the association between polycystic ovaries, hyperandrogenism and hyperinsulinemia and described that polycystic ovary syndrome was not only a cause of infertility

    Full Text Available Objetivo: presentar el reporte de un caso correspondiente a leiomioma primario de ovario. Este corresponde a un tipo de lesión poco común del ovario. Descripción del caso: mujer de 46 años de edad, a la cual se le realizó un control por historia de masa anexial derecha, con hallazgo ultrasonográfico de masa ovárica derecha de 45 x 36 mm de aspecto homogéneo, sólida y encapsulada. Se realizó histerectomía total y ooforectomía bilateral. El estudio histopatológico demostró que se trataba de un leiomioma primario de ovario. En el estudio inmunohistoquímico se demostró negatividad en las tinciones de alfa inhibina y S-100, mientras que la tinción de actina de músculo liso y la vicentina fueron positivos, consistente con un leiomioma primario de ovario. Discusión: los leiomiomas primarios de ovario son tumores poco frecuentes y muchas veces subdiagnosticados. Son de evolución benigno, con una sobrevida de 100% a los 5 añosObjective: report a case of ovarian primary leiomyoma. Ovarian leiomyomas are rare ovarian lesions. Case: The patient is a 46 years old female, who underwent sonographic pelvic examination for for right adnexal mass control. A right ovarian mass was discovered, that measured 45 x 36 mm. the appearance was homogeneous, and it was described solid and encapsulated. Histerectomy and bilateral oophorectomy was performed. Histopathologic study was consistent with a primary ovarian leiomyioma. Immunohistochemical results were inhibina and S-100 negative and smoot muscle actin and vimentin was positive, consistent also with a primary ovarian leiomyoma. Discussion: These tumors are frequently underdiagnosed due their rarity. They are benign with a survival rate 0f 100% at five years

    Full Text Available Resumen La metformina es un medicamento indicado para el tratamiento de la diabetes mellitus tipo II con una función renal normal. Ha sido usada, sin la aprobación de la Administración de Drogas y Alimentos de los EEUU, en pacientes con el síndrome del ovario poliquístico, como regulador del trastorno menstrual, tratamiento del hirsutismo e inductor de ovulación. Desde 1980, Burghen y colaboradores señalaron la asociación entre el hiperandrogenismo y la hiperinsulinemia en el síndrome del ovario poliquístico. El exceso de andrógenos, resultado del aumento de la insulina, deteriora la acción de esta. Los efectos de la metformina en la disminución de la glucosa son consecuencia de una reducción en la producción de glucosa hepática y un aumento en su empleo. Este medicamento incrementa la mayoría de las acciones biológicas de la insulina en personas con resistencia a la insulina preexistente y disminuye la absorción intestinal de glucosa. Se concluye que la metformina es útil en la regulación el ciclo menstrual en comparación con el placebo; no es un tratamiento de primera elección en el hirsutismo y su uso como monoterapia en la inducción de la ovulación no demuestra sustancialmente mejoría en la tasa de embarazo clínico. La evidencia señala que la metformina asociada con el citrato de clomifeno induce la ovulación y mejora la tasa de embarazo clínico.

    Full Text Available Objetivo: Evaluar perfil hormonal, índice de masa corporal y tensión arterial en 40 mujeres infértiles con ovario poliquístico. Métodos: En la consulta del Centro de Atención Integral de la Universidad de Los Andes se valoró talla, peso y tensión arterial. Durante la fase folicular del ciclo menstrual en ellas se midió en sangre las hormonas sexuales e insulina (basal y 2 horas poscarga glucosada por electroquimioluminiscencia. Resultados: El índice de masa corporal se correlacionó directamente con el valor de tensión arterial sistólica, la relación LH/FSH y la testosterona sérica; e inversamente con las hormonas FSH y PRL. Los datos clínicos y de laboratorio se observaron dentro de los límites de referencia; sin embargo, la testosterona guardó relación directa con LH/FSH, índice de masa corporal y tensión arterial sistólica. Al compararse dos grupos de paciente con base al valor de la mediana poblacional, los grupos masa corporal > 24 kg/m2 y tensión arterial sistólica >120 mmHg mostraron niveles de DHEA-S e insulina (basal y 2 h más elevados que en mujeres con índice de masa corporal y tensión arterial sistólica más bajos. Conclusiones: Existe correlación entre niveles séricos de andrógenos con sobrepeso e hipertensión arterial por mecanismos etiológicos interrelacionados. Síndrome de ovario poliquístico es de origen multicausal eventualmente con hiperandrogenemia. La falla metabólica debe controlarse en estas pacientes, lo que permitiría bajar el efecto de los andrógenos y favorecer el estado de fertilidad, pero sobre evita a largo plazo complicaciones como obesidad, diabetes mellitus tipo 2 e hipertensión arterial.

    Full Text Available El coipo (Myocastor coypus es un roedor de amplia utilización como especie peletera a escala mundial. Los ambientes naturales ocupados por el coipo son los acuático-continentales, si bien la especie ha demostrado gran adaptabilidad a diferentes ambientes y regiones geográficas. A partir de su liberación accidental de granjas de cría, se localizan poblaciones naturalizadas en Inglaterra, EEUU, países del Este europeo, Kenia e Israel. El objetivo de este trabajo fue caracterizar la anatomía e histología del ovario del coipo en la madurez sexual. Los órganos se procesaron con técnicas de rutina, se cortaron en forma seriada cada 5 mm y se colorearon con hematoxilina de Harris y eosina, tricrómica de Masson, tricrómica de van Gieson, impregnación argéntica, orceína y ácido peryódico-reactivo de Schiff. Los ovarios se ubicaron en proximidad del polo caudal del riñón, presentaron forma ovoidal y color cremoso blanquecino y estuvieron sostenidos por el mesovario, insertado a lo largo de su diámetro mayor. Las fimbrias oviductales rodearon parcialmente al ovario. El tamaño medio de los ovarios fue de 0.81 ± 0.16 x 0.40 ± 0.06 x 0.42 ± 0.07 cm. En la mayoría de las hembras la superficie ovárica fue lisa, pero en algunos animales se observó un aspecto superficial ligeramente lobulado. El epitelio de revestimiento fue una capa simple de células planas o cúbicas con núcleos ovales o redondos y citoplasma acidofilo. Las células superficiales varíaron en altura desde 6 a 10 mm, siendo su altura media de 7.96 ± 1.34mm. Todos los elementos del ovario se encuentraron en una malla de tejido conectivo con abundantes células estromáticas. El aspecto general de estas células fue fusiforme con núcleos ovales o planos. La túnica albugínea (de 36.59 ± 4.99 mm de ancho, bien desarrollada, presentó dos capas. La externa constituída por fibras conectivas, orientadas en forma perpendicular a la superficie; la capa interna

    2015-01-01

    Full Text Available El estado morfofuncional del sistema reproductivo de las ovejas es determinado por las hormonas sexuales, que actúan por medio de receptores específicos, desencadenando una serie de cambios celulares, metabólicos y proliferativos dependientes de la expresión de numerosos genes. A diferencia de otros mamíferos, las ovejas presentan en el endometrio y posiblemente otros órganos del sistema reproductivo receptores de estrógenos fisiológicamente activos desde la etapa prepuberal cuya función aún no está esclarecida. La información sobre la expresión de receptores de hormonas sexuales en el aparato reproductor es muy escasa, sobre todo en el ovario y no existen estudios que correlacionen la raza con la expresión de estos receptores. Generalmente los criadores privilegian razas de mayor nivel de prolificidad y esto podría estar relacionado con el nivel de expresión de los receptores de estrógeno en el sistema reproductivo. El objetivo del presente trabajo fue evaluar comparativamente la expresión transcripcional del receptor de estrógeno en el ovario de ovejas prepúberes de raza Texel de alta prolificidad y de raza Criolla Araucana de prolificidad estándar, mediante análisis de RT-PCR en tiempo real cuantitativo.

De acuerdo al tamaño, los ovarios se clasificaron en pequeños (1,0-2,4 cm; medianos (2,5-3,5 cm y grandes (3,6-5,0 cm. El 59 y el 51% de las novillas F1 mostraron ovarios pequeños y medianos respectivamente. El 34, 53 y 13% de las vacas F1 presentaron gónadas pequeñas, medianas y grandes respectivamente. El 88 y el 12% de las vacas F2; el 87 y el 13% de las F3 y el 80 y el 20% de las F4 tuvieron ovarios pequeños y medianos respectivamente. El tipo de ovario grande y aplanado no se encontró en estas vacas. La cérvix de tamaño grande, típica del ganado Cebú, se observó en el 10% de las vacas F1, en el 4% de las F2, en el 6% de las F3 y en el 10% de las F4. A medida que el cruzamiento absorbente tendió hacia el Bos taurus, la frecuencia de aparición de los tres tipos de ovarios, principalmente el grande y abollonado, disminuyó hasta casi desaparecer ya en el cruce F2, pero el tipo de ovario pequeño se mantuvo con una frecuencia alta. En cambio, la cérvix del tipo grande y encorvada tendió a disminuir con el incremento de genes Bos taurus. Abstract For this work was carried out the direct biometry of ovaries and cervix of 80 heifers and 80 cows crossbred Holstein x Zebu (F1 slaughtered. In the crossbred cows F2, F3 and F4 the measures of those organs were estimated clinically.

Según el diámetro mayor, los ovarios se clasificaron en pequeños (1,0-2,4 cm y redondeados, medianos (2,5-3,5 cm y redondeados u ovoides y grandes (3,6-5,5 cm y aplanados. En las novillas predominaron los ovarios medianos (62% y pequeños (36% y en las vacas medianos (65% y grandes (20%. El 45% de las vacas tuvo cervices grandes y encorvados. Además, se realizó la biometría indirecta por vía rectal de 200 novillas y 200 vacas Cebú cubana. En las novillas el 75% de ovarios fue pequeño y el 25% medianos. En las vacas el 78% de los ovarios fue pequeño y el 21% mediano. La frecuencia de ovarios pequeños fue el doble más alta en la raza Cebú cubana que en la Cebú comercial. Las diferencias entre los valores de IPPI, PS e II para los tres tamaños de ovarios en las dos épocas del año (lluvia y seca, no fueron significativas. Los coeficientes de correlación entre el tamaño de los ovarios y el IPPI, la masa corporal y la edad fueron de r = 0,057, r = 0,084 y r = 0,098 respectivamente. Los cuellos uterinos hipertrofiados y desviados no afectaron la permeabilidad del conducto ni la fertilidad. Se concluye que, los ovarios y la cérvix de las hembras Cebú pueden ser diferentes de las Bos taurus en cuanto a su tamaño y a su forma. It was carried out a direct biometrics study of the genital organs of 100 heifers and 150 cows commercial Zebu breed slaughtered.

    Full Text Available Em uma mulher, brasileira, de côr parda, com 48 anos de idade, morta com tuberculose do peritoneo, tuberculose peribronquica do lóbo superior do pulmão esquerdo e tuberculose cronica fibrosa do apice de ambos os pulmões, a necropsía revelou a existencia de um teratoma no ovario esquerdo. O ovario, pouco aumentado de volume, é constituído por duas porções de tamanho sensivelmente egual, de consistencia firme, separadas, em sua superficie, por profundo sulco. Ao córte, tem a aparencia de tecido fibroso em cuja espessura existem numerosos pequenos cistos. Ao microscopio, os cistos são revestidos por epitelio descontinuo, despertando grande interesse o seu conteúdo. Este é formado por fibras e células com morfologia semelhante ás do cristalino. Sugerimos a possibilidade de que, no presente teratoma (Teratoma lentifer, de lens, lentis: cristalino, e ferre: produzir haja participado, de modo dominante, o ectodérme, e mesmo uma região circumscrita do ectodérme, a qual corresponderia aquela emque se desenvolve, habitualmente, a placa do cristalino (« Linsenplatte ». A multiplicidade e a presença exclusiva de estruturas figurando saculos cristalinicos (« Linsensäckchen » são argumentos a favor de uma origem de ponto restrito do ectodérme, destinado a desenvolvimento posterior especifico, qual o da formação do cristalino.

    Full Text Available El desequilibrio de factores autocrinos/paracrinos en el ovario conduce a diversas enfermedades. El objetivo del presente trabajo fue evaluar la relación entre el factor de crecimiento insulínico 1 (IGF-1 y la leptina (Lp en la producción de progesterona (P y estradiol (E por el ovario de rata estimulado con hormona folículo estimulante (FSH. Para ello, se incubaron explantes ováricos con FSH, IGF-1 y Lp, evaluándose P y E en el sobrenadante por radioinmunoensayo. La FSH estimuló la producción de P y E por el ovario. El IGF-1 produjo un importante efecto sinérgico con FSH tanto en la síntesis de P como de E. La Lp no tuvo efecto sobre la acción de FSH en el aumento de P y E por el ovario, sin embargo revirtió el efecto sinérgico de IGF-1 sobre FSH tanto para P como para E. Podemos concluir que la Lp podría actuar directamente disminuyendo el efecto sinérgico de IGF-1 sobre FSH. Estos resultados podrían sugerir que niveles anormales de Lp encontrados en mujeres con síndrome de ovario poliquístico provocarían una desensibilización ovárica al IGF-1 que afectaría la producción de P y E.An alteration in the balance of autocrine/paracrine ovarian factors may lead to different diseases. The aim of the present report was to evaluate the relationship between insulin growth factor 1 (IGF-1 and leptin (Lp in the progesterone (P and estradiol (E production after ovarian rat FSH stimulation. Thus, ovarian explants were incubated with FSH, IGF-1 and Lp, and P and E were evaluated by means of specific radioimmunoassays. FSH increased ovarian P and E production. IGF-1 synergized with FSH in P as well as in ovarian E production. Lp had not shown any effect on the FSH capacity to increse P and E in the ovarian tissue; nevertheless it reverted the synergistic effect of IGF-1 on FSH for P as well as for E. These data raise the possibility that abnormal Lp levels may contribute to infertility in women with polycystic ovarian syndrome by

    Full Text Available Ovarian tumors are not as common as uterus and breast tumors. They are regarded as the third group of women benign and malignant tumors. Ovarian serous cystadenomas arise from the superficial coelomic epithelium and are composed of cystic areas. There are macroscopically small tumors and massive tumors occupying the entire pelvis and even the abdominal cavity. The case of a 57 years old female patient with a history of apparent good health that attended consultation because of abdomen enlargement after a year of evolution is presented. The patient referred also nausea, loss of appetite and abdominal left flank pain. She was treated at the General Surgery Department of the General University Hospital "Dr. Gustavo Aldereguía Lima". Left oophorectomy was performed. Histopathological examination showed a giant serous ovarian cystadenoma. Pos-surgery evolution was satisfactory.Los tumores del ovario no son tan frecuentes como los del útero y los de la mama. Constituyen el tercer grupo de tumores benignos y malignos de la mujer. El cistadenoma seroso de ovario se deriva del epitelio superficial (celómico, formado por áreas quísticas. Hay tumores pequeños macroscópicamente y tumores masivos que ocupan toda la pelvis e incluso la cavidad abdominal.

    Full Text Available Para entender los mecanismos de maduración, fertilización y desarrollo embrionario en el ganado bovino, es necesario la identificación y caracterización de microRNAs (miRNAs involucrados en la regulación del crecimiento del ovocito y la transición ovocito-embrión. Con el objetivo de identificar nuevos miRNAs, con una posible función dentro del proceso de maduración del ovocito y de embriogénesis temprana, se realizó una librería genómica con miRNAs provenientes de ovarios de vacas de rastro. Al analizar los concatámeros de 40 clonas se identificaron dos nuevos miRNAs, bta-mir-8548 y bta-mir-8549, cuyos pre-miRNA mostraron una estructura tallo-burbuja estable, según los parámetros establecidos por el miRBase. El bta-mir-8548 se ubicó en el cromosoma 8 en una región intrónica entre los exones 1 y 2 del gen MRSA (metionina sulfóxido reductasa, sugiriendo que puede tener una función en la regulación del estrés oxidativo durante la maduración del ovocito. El bta-mir-8549 se ubicó en el cromosoma 7 en la región intergénica entre los genes tRNA-Cys y GBPg5. La forma madura de este miRNA mostró la secuencia conservada propia de la familia de miRNAs bta-let-7, los cuales están relacionados con los procesos de maduración del ovocito. Para ubicar el lugar de bta-mir-8549 dentro de la familia de miRNAs bta-let-7 se realizó un estudio filogenético. El cladograma generado a partir de las distancias genéticas entre los miRNAs bta-let-7 indicó que bta-mir-8549 se situó de forma monofilética con bta-let-7c, mientras que el resto de los bta-let-7 quedaron ubicados en clados diferentes. En conclusión, bta-mir-8548 y bta-mir-8549 son nuevos miRNAs aislados de ovario bovino los cuales podrían actuar en los mecanismos de regulación de la maduración del ovocito y durante el desarrollo embrionario.

    Carlos Arturo Vivas

    2005-12-01

    Full Text Available El síndrome de ovario poliquístico (SOP es la endocrinopatía más frecuente en mujeres en edad reproductiva, se observa en el 5-7% de ellas. El diagnóstico se hace ante la presencia de por lo menos dos componentes de la triada: oligoovulación, hiperandrogenismo y ovarios poliquísticos. Estas mujeres tienen niveles elevados de lutropina (LH, hiperinsulinemia e hiperandrogenismo y se ha reportado un aumento en la incidencia de aborto en este grupo de pacientes. Este hecho podría estar relacionado con los cambios endometriales observados en estas mujeres y que se asocian a niveles elevados de andrógenos e insulina, provocando así, inadecuada implantación y probablemente mayor pérdida del embarazo en el primer trimestre. Medidas terapéuticas, como el uso de sensibilizantes a la acción de la insulina, que contribuyen a disminuir los niveles de insulina y por lo tanto de andrógenos, podrían tener un efecto favorable al disminuir la incidencia de aborto en pacientes con SOP.Polycystic ovarian syndrome is the most frequent endocrinopathy in reproductive age women (5-7%. The diagnosis is made when two out of three components are present, such as hyperandrogenism, polycystic ovaries and oligoovulation. These women have high levels of luteinizing hormone (LH, hyperisulinemia and hyperandrogenism and an increased rate of abortion has been reported in these patients. This fact could be related to changes found in the endometrium and the elevated serum levels of androgens and insulin. These changes can lead to an inadequate implantation and probably to an increase in first trimester pregnancy losses. Therapeutic approaches such as the use of insulin-sensitizing drugs to decrease insulin levels could be useful in decreasing abortion rates in these patients.

    Full Text Available Contexto: La primera idea que tuvieron los cirujanos (1902 para evitar amputaciones por isquemia fue la de desviar el flujo arterial al sistema venoso por intermedio de una fístula arteriovenosa entre vasos adyacentes, pero con resultados inciertos. Desde entonces se han inventado las simpatecomias, las endarteriectomias y los injertos puentes o bypass y, últimamente, otros avances médicos, quirúrgicos y endovasculares. Sin embargo, en el mundo se siguen haciendo amputaciones, sobre todo en diabéticos. La arterialización de las venas del pie, basada en la vieja idea de la circulación invertida, constituye una esperanza más para estos pacientes ya condenados a la pérdida del miembro. Objetivo: Demostrar que la arterialización de las venas del pie en diabéticos con lesiones neuroisquémicas, generalmente infectadas (pie diabético, es un método eficaz y durable, aunque el puente solo funcione temporalmente. Pacientes y método: De enero de 2000 a febrero de 2009, 59 pacientes con pie diabético fueron tratados por arterialización de las venas del pie. Un deceso precoz no ha sido contabilizado. De los 58 pacientes restantes, 44 fueron hombres y 14 mujeres, con edad promedio de 71 años: (53-91 años, 54 en estado IV de Fontaine y cuatro en estado IIIB. La arterialización fue hecha con un injerto venoso invertido anastomosado, proximalmente en una arteria con buen flujo (ilíaca externa, femorales o poplítea distalmente en la vena marginal interna del pie, con destrucción de las válvulas de las venas del dorso. Resultados: De los 58 arterializados, 12 fueron fracasos por trombosis precoz, siendo amputados, y 46 fueron éxitos (79%: seis de corto, 12 de mediano y 28 de largo plazo. En los grupos que se ajustan a la definición de éxito (dos hubo 38 trombosis tardías del puente (95% y cuatro recidivas de la sintomatología isquémica.

    Full Text Available Descripción morfológica de las estructuras reproductivas de Austromegabalanus psittacus en dos periodos de maduración sexual. Se determinó que es un organismo hermafrodita que transfiere sus espermatozoides mediante un órgano intromitente o pene. El aparato reproductor masculino consta de testículos organizados en acinos que se distribuyen arboriformemente, dos conductos deferentes que se unen en la base del pene para formar el conducto eyaculador. El aparato reproductor femenino consiste principalmente en un ovario sacular que rodea al resto del cuerpo y se encuentra adherido a través de musculatura a la base de las placas operculares. Se organiza internamente en sacos acinares elongados que contienen ovogonias y ovocitos previtelogénicos adheridos a su pared y vitelogénicos y maduros libres dentro del lumen. Se observaron diferencias notorias en los ovarios entre los organismos recolectados en septiembre y octubre. En septiembre presentaron coloración amarillenta y en su interior se encontraron dos estructuras compactas denominadas lamelas ovígeras en cuyo interior se observaron ovocitos fecundados, embriones en diferentes estados de desarrollo y nauplius libres en la cavidad corporal; en octubre los ovarios son gruesos, blanquecinos y con gran cantidad de fluido lechoso en su interior.

En este artículo presentamos el caso de un paciente de 42 años con oclusión total de este vaso, que presentaba además, una estenosis de 85 % en la arteria coronaria derecha y fue revascularizado quirúrgicamente de forma exitosa. Se implantaron 3 injertos, mamaria a la descendente anterior, y vena safena a una obtusa marginal y a la descendente posterior. Se presentan las imágenes angiográficas y de la cirugía, y se comentan las alternativas terapéuticas, donde lo más importante es individualizar el tratamiento, con el objetivo de brindar la mejor opción a cada paciente en particular. Para lograrlo es imprescindible una excelente relación del equipo de trabajo donde, como en este caso, el cardiólogo intervencionista y el cirujano cardiovascular se complementen, para el bien del paciente. AbstractThe left main coronary artery stenosis is found in 3-5 % of patients who undergo coronary angiography, but total occlusion is rare (0,05-0,1 %. In this article, the case of a 42-year-old patient with chronic total occlusion of the left main coronary artery is presented. This patient, who also had 85 % stenosis of the right coronary artery, was surgically and successfully revascularized. 3 grafts were implanted: mammary artery to the anterior descending artery and saphenous vein to the obtuse marginal and posterior descending artery. The angiographic and surgery images are shown, and treatment options are discussed, where the most important thing is to individualize treatment in order to provide the best option for each patient.

    Full Text Available Antecedentes. El conocimiento exacto de la integración anatomofisiológica del sistema de conducción del corazón, es fundamental para la comprender la fisiopatología, el diagnóstico y el manejo de muchas de las complicaciones de la enfermedad coronaria y de las cardiopatías en general. Uno de los aspectos fundamentales, más variable y con mayores repercusiones clínicas corresponde al origen y recorrido de las arterias encargadas de irrigar el nódulo sinoatrial. Objetivo. Determinar el origen, recorrido y distribución de las arterias que irrigan el nódulo sinoatrial en una muestra de población colombiana. Material y métodos. La muestra de análisis fueron 60 bloques cardiopulmonares y digestivos seleccionados a través de muestreo por conveniencia. A estos se les realizó una disección convencional de los genitales para la determinación del sexo y posteriormente se procedió con la disección de las arterias coronarias específicamente de la arteria del nódulo sinoatrial, con el fin de establecer su origen y recorrido. Resultados. Como hallazgo principal se encontró que el origen de la arteria del nódulo sinoatrial en 75% provenía de la coronaria derecha, un 15% procedía de la arteria circunfleja y el 10% restante fue codominante. En cuanto al trayecto 86,6% fueron lineales, mientras 13,4% tuvieron formas alternas como Y, doble Y o en tridente. Conclusiones. Se evidenció predominio del origen de la arteria del nódulo sinoatrial en la coronaria derecha, hallazgo coincidente con investigaciones similares e independiente de la procedencia geográfica y el origen racial. Sin embargo, en este estudio se evidenciaron recorridos no reportados en la literatura como la distribución en Y, en doble Y, en K invertida y en tridente.Background. Accurate knowledge regarding the cardiac conduction system's anatomical-physiological integration is essential for understanding the pathophysiology, diagnosis and management of many complications

    Full Text Available Many hypertensive patients affected by endogenous Cushing's syndrome (CS persist with high blood pressure (HBP despite good control of cortisol excess. We assessed the effect of preoperative ketoconazole administration and of definitive treatment of CS on arterial hypertension and analysed the factors involved in the persistence of hypertension. We assessed retrospectively 71 patients with CS and HBP (60 women, 11 men; 50 pituitary, 21 adrenal successfully treated by surgery and/or radiotherapy; 19 of them received ketoconazole (KNZ before surgery. After treatment, patients were divided into those with persistent high blood pressure (PHBP and those with normal blood pressure (NBP. As possible predictive factors for PHBP we analysed age, duration and family history of HBP, pre-treatment 24 hour urinary free cortisol (24h-UFC and body mass index (BMI. HBP normalized in 53 out of 71 patients (74.6%, regardless of the origin of Cushing's syndrome. PHBP patients were older (p=0.003, had longer duration (p=0.007 and higher systolic blood pressure before treatment (p=0.046 than NBP patients. Thirteen out of 19 patients (68.4% treated with ketoconazole, normalized their hypertension and remained normotensive after successful surgery. Five patients became normotensive only after surgery. In conclusion: a blood pressure levels normalized in most patients after remission of CS; b ketoconazole was effective for the control of HBP, and seems to be a good indicator of post-surgical outcome, and c higher age at presentation, longer duration of hypertension and higher systolic blood pressure figures before treatment negatively influence normalization of blood pressure after resolution of Cushing's syndrome.Muchos pacientes con síndrome de Cushing (SC permanecen hipertensos a pesar del control del exceso glucocorticoideo.

La búsqueda bibliográfica se realizó siguiendo los principios que rigen el "método de revisión sistemática" (systematic review. En muchos de los artículos y trabajos revisados, se ha demostrado, que el Síndrome Metabólico (SM y PCOS están fisiopatológicamente vinculados, ya que ambos comparten, como central elemento en su mecanismo fisiopatológico, la resistencia a la insulina (IR. Dicha IR produce un efecto deletéreo sobre la función vascular, es decir que la misma coexiste junto a una disfunción vascular generalizada, lo cual se refleja en la excresión aumentada de albúmina en orina, más precisamente microalbuminuria. Luego de haber realizado una búsqueda sistemática del tema en todas las bases de datos internacionales, podemos concluir que existen numerosos artículos e investigaciones en los que se describe en detalle la alta tasa de incidencia de hipertensión entre las pacientes con PCOS. Por el contrario, la presencia de microalbuminuria (MA como marcador de riesgo de enfermedad macro/ microvascular en pacientes con PCOS, está pobremente descripta; pero los escasos artículos encontrados señalan una alta prevalencia de la misma (16% o 24% dependiendo de los criterios con los que se define MA y de premicroalbuminuria (PMA (31,2% entre estas pacientes.

Algunos de estos modelos consideran isotropía del material pero han demostrado no ser adecuados paramodelar el comportamiento de arterias sanas. Los modelos más difundidos en este sentido consideran el material anisotrópico debido a la organización de las fibras de colágeno y a pesar de haber sido formulados para describir la conducta arterial pueden ser utilizados para representar el comportamiento de otros tejidos blandos como la vena cava infra-renal, la pared intestinal, las propiedades mecánicas del esófago, entre otros. Algunos autores incluso los han utilizado para modelar también el daño en las arterias.Palabras claves: modelo constitutivo, tejido arterial, elasticidad, pared aortica, análisis de tensiones, respuesta pasiva._________________________________________________________________________________AbstractArterial walls are one of the soft tissues found in living organism.

    de presión arterial de reposo, siendo importante analizar los efectos del ejercicio de resistencia sobre la presión arterial de individuos añosos. El objetivo de este estudio es evaluar el conocimiento científico existente sobre la respuesta de la presión arterial a los ejercicios de resistencia y sus mecanismos en añosos. Para esto, se realizó una revisión bibliográfica basada en la literatura portuguesa e inglesa relacionadas al tema. Con base en los estudios encontrados, el corpus actual, a pesar de ser escaso y controvertido, sugiere que, de forma crónica, los ejercicios de resistencia pueden tener efecto hipotensor en individuos añosos. Entre tanto, este efecto ocurre, principalmente en añosos normotensos y con entrenamiento de baja intensidad. Los mecanismos envueltos en esa respuesta hipotensora todavía precisan ser elucidados. Aunque el entrenamiento con resistencia esté siendo recomendado para añosos y haya algunos indicativos de que pueda tener efecto hipotensor crónico, todavía hay carencia de datos científicos y muchas controversias en el asunto, lo que evidencia que éste todavía es un campo abierto a la investigación.The aging process drastically reduces muscle mass, strength and power, decreasing the capacity to perform the activities of daily living. The practice of resistance exercises can reverse this picture, helping to maintain the muscular mass and improving muscular strength and resistance. However, the aging process causes cardiovascular alterations, which can result in increased blood pressure levels at rest and it is important to analyze the effects of resistance exercises on the blood pressure of elderly individuals. The objective of this study is to evaluate the current scientific knowledge on the responses of the blood pressure to resistance exercises and their mechanisms in elderly individuals. In order to do that, we carried out a literature review related to the theme, in both Portuguese and English. Based on the

    Full Text Available A apneia obstrutiva do sono (AOS é uma condição clínica comum na população em geral, principalmente entre os pacientes portadores de doenças cardiovasculares. Mais do que um fenômeno local de obstrução das vias aéreas superiores, a AOS traz repercussões sistêmicas que podem incluir a hipóxia intermitente, a redução abrupta da pressão intratorácica e a ocorrência de microdespertares com fragmentação do sono. Nas últimas décadas, inúmeras evidências apontam de forma consistente a AOS como um importante fator envolvido na ocorrência de doenças cardiovasculares. Particularmente, a relação entre a AOS e a hipertensão arterial sistêmica (HAS é a que encontra um maior conjunto de evidências. Atualmente, encontram-se dados que consideram a AOS uma importante causa secundária de HAS. Mais do que isso, a AOS está independentemente associada a um pior controle pressórico, alteração do descenso noturno da pressão arterial e à presença de lesões de órgãos-alvo, tais como a hipertrofia do ventrículo esquerdo e a microalbuminúria. Estudos randomizados sugerem que o tratamento da AOS, especialmente com a pressão positiva contínua de vias aéreas superiores (CPAP, considerado o tratamento padrão para a AOS, promove redução significante da pressão arterial nas 24 horas, efeito esse mais significante no subgrupo de pacientes com HAS não controlada e nos pacientes com HAS resistente. A despeito de todas essas evidências, a AOS ainda continua sendo subdiagnosticada. O objetivo desta revisão é discutir os recentes avanços nos mecanismos fisiopatológicos, na apresentação clínica e no tratamento da AOS, e o benefício sobre a pressão arterial.La apnea obstructiva del sueño (AOS es una condición clínica común en la población en general, principalmente entre los pacientes portadores de enfermedades cardiovasculares.

    Arterial ageing is characterized by age associated degeneration and sclerosis of the media layer of the large arteries. However, besides ageing, clinical conditions, which enhance oxidative stress and inflammation act to accelerate the degree of arterial ageing. In this review, we summarized the pathophysiology and contributing factors that accelerate arterial ageing. Among them, we focused on hypertension, the renin-angiotensin-aldosterone system and vascular inflammation which are modifiabl...

    Full Text Available OBJETIVO: Descrever, por meio de uma revisão sistemática, os efeitos do treinamento físico sobre a pressão arterial em adolescentes com obesidade. FONTES DE DADOS: Recorreu-se à revisão sistemática de ensaios clínicos randomizados que analisaram o efeito do treinamento físico sobre a pressão arterial de adolescentes obesos, publicados em periódicos indexados nas bases de dados PubMed/Medline, Lilacs, SciELO e ISI Web of KnowledgeSM. Foram incluídos os estudos que avaliaram adolescentes publicados até 2010, e que possuíam Grupo Controle. SÍNTESE DOS DADOS: Oito estudos atenderam aos critérios de inclusão. Dois deles utilizaram exercícios de força combinados com aeróbios, enquanto seis empregaram apenas os aeróbios. Cinco estudos utilizaram intervenções complementares, sendo a nutricional a mais frequente. Quatro estudos observaram redução da pressão arterial sistólica no Grupo Exercício comparado ao Controle. Nesses quatro estudos, além da redução da pressão arterial, notou-se diminuição da massa corpórea. Todos aqueles que verificaram redução da pressão arterial utilizaram 12 a 24 semanas de exercícios aeróbios, três a seis sessões semanais, com duração de 50 a 90 minutos e intensidade entre 55 e 75% da frequência cardíaca máxima. CONCLUSÕES: O efeito do treinamento físico na pressão arterial de adolescentes obesos é controverso. A redução da pressão arterial parece ocorrer com programas de treinamento aeróbios que promovam também a redução da massa corpórea.OBJETIVO: Describir, mediante una revisión sistemática, los efectos del entrenamiento físico sobre la presión arterial en adolescentes con obesidad.

O objetivo deste artigo é relatar um caso de disfonia no pós-operatório tardio, decorrente de paralisia de prega vocal esquerda, devido à lesão do nervo laríngeo recorrente esquerdo, durante cirurgia de ligadura do canal arterial. RELATO DO CASO: Paciente do sexo feminino, 6 anos, estado físico ASA II, peso 18.800 g, submetida à cirurgia para ligadura do canal arterial. Recebeu como medicação pré anestésica, midazolam (0,8 mg.kg-1, 60 minutos antes da cirurgia. A indução e a manutenção da anestesia foram feitas com sevoflurano, alfentanil e pancurônio. A dissecção do canal arterial foi realizada com dificuldade. No 4º dia do pós-operatório apresentou disfonia persistente. A videolaringoscopia mostrou paralisia de prega vocal esquerda e pequena fenda paramediana. CONCLUSÕES: Pela sua íntima relação com o canal arterial, o nervo laríngeo recorrente esquerdo pode ser lesado, durante a cirurgia corretiva, principalmente quando existem dificuldades na dissecção e ligadura do canal arterial. Diferentemente das disfonias decorrentes da intubação e extubação traqueal, surgem mais tardiamente e permanecem por longos períodos, podendo inclusive serem irreversíveis.JUSTIFICATIVA Y OBJETIVOS: Aun cuando las disfonias pós-operatorias sean frecuentemente asociadas a complicaciones de la intubación y extubación traqueal, otras causas pueden estar envolvidas, incluso quirúrgicas.

Constituyó una rara lesión intra-abdominal, que pudo provocar abdomen agudo. Fue interpretado inicialmente como quiste de ovario gigante. La ausencia de ecografía abdominal y la presencia de distensión y masa palpable asintomática decidieron la intervención quirúrgica. Se realizó una cuidadosa preparación preoperatoria, que incluyó la antisepsia local de la piel y la administración de ceftriaxona, como antibiótico profiláctico. Durante la laparotomía exploradora se constató un quiste gigante del mesenterio del intestino delgado, de 17 cm de longitud, localizado a nivel del íleon terminal y sujeto por un pedículo ampliamente vascularizado. La técnica quirúrgica consistió en la exéresis total de la lesión y no se requirió de resección intestinal ante la ausencia de oclusión intestinal. Los hallazgos anatomo-patológicos informaron proceso benigno. No se reportaron complicaciones y la paciente evolucionó satisfactoriamente, reportándose una estadía hospitalaria de cinco días

Cardiac Rehabilitation represents one of the fundamental parts of the treatment, combined with pharmacological therapy and revascularization procedures for coronary artery disease. The objectives of this study were to evaluate the impact of a cardiac rehabilitation program, in the quality of life of patients and their families and to become aware of factors that can interfere with the rehabilitation process. Methods: This is an observational, transverse study of patients with coronary artery diseases, with at least six month of assistance to the cardiac rehabilitation program of our hospital, up to October 2005. We used a mixed instrument of data recollection, composed of a supervised written inquiry and complemented with the measure of quantifiable variables. Results: There were no significant differences in gender population. 98% considered an improvement in their quality of life. 97% considered that their family understood better their illness, but only 45% reported integration of the family to the program. The data obtained from the stress test showed that 74% had a negative stress test for ischemia, 25% positive for ischemia and 1 % positive for high risk ischemia.

    2001-01-01

    Full Text Available Background: The hepatic arterial anatomy is aberrant in almost 33-41% of individuals. The variant arterial anatomy recognized during routine cadaveric dissection offers great learning potential. Such findings provide an alternative perspective to view common morphology and its structural and functional importance. These impart the concept of patient individuality and subsequent individualization of medical and surgical therapies. Adequate knowledge of normal and abnormal arterial anatomy is essential for peripancreatic surgery and liver transplantation. Aims of the study: To report on hepatic artery variations observed in the dissecting room and to find out the macroscopic pattern of varied human hepatic arterial vascularization by cadaveric dissection. Patients and Methods: Twenty human cadavers of caucasian origin were dissected to study the source and topographic pattern of hepatic arterial supply. Results: Nineteen cadavers exhibited typical hepatic arterial supply from the celiac axis. Only one female body out of twenty cadavers exhibited a dual arterial supply to all parts of liver and gallbladder. One artery originated from the celiac axis whereas the other was given off by the superior mesenteric artery. Conclusion: No doubt, aberrant hepatic vascularization should be assessed preoperatively by invasive and noninvasive techniques to avoid fatal complications, but we favour careful dissection over angiography as a means of defining the arterial anatomy.

    Although conventional intraarterial digital subtraction angiography remains the gold standard method for imaging the vertebral artery, noninvasive modalities such as ultrasound, multislice computed tomographic angiography and magnetic resonance angiography are constantly improving and are playing an increasingly important role in diagnosing vertebral artery pathology in clinical practice. This paper reviews the current state of vertebral artery imaging from an evidence-based perspective. Normal anatomy, normal variants and a number of pathological entities such as vertebral atherosclerosis, arterial dissection, arteriovenous fistula, subclavian steal syndrome and vertebrobasilar dolichoectasia are discussed.

    Full Text Available La incidencia de hipertensión arterial pulmonar (HP en pollosparrilleros constituye un problema económico importante. Dentrode los mecanismos de adaptación del organismo a la altitud se encuentran,además del aumento de la tensión arterial pulmonar, el incremento de la masa muscular ventricular derecha, la policitemía y posiblemente la hiperventilación con la subsecuente alcalosis respiratoria. Es factible que el alto nivel de energía en la ración incremente la hipoxemia derivada de la hipoxia; con lo anterior, el grado de policitemia se puede elevar y producirse un efecto agravante de la HP. Para establecer valores de pO2, Ht, Hb e IC en pollos parrilleros residentes a 2.600 m de altura sobre el nivel del mar, se estudiaron 24 aves de ambos sexos, de una población de 400 animales.

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    Full Text Available La hipertensión arterial es uno de los principales factores de riesgo cardiovascular; la tendencia mundial al incremento de la expectativa de vida ha propiciado un tránsito mayor al envejecimiento y simultáneamente un incremento de su prevalencia. Las evidencias científicas para apoyar la efectividad de la auriculoterapia en el tratamiento de esta enfermedad resultan aparentemente insuficientes, por lo que muchos profesionales de la salud la desestiman, lo que dio motivo a realizar un trabajo de revisión de la literatura científica, con el objetivo de abordar aspectos relacionados con la aplicación de la auriculoterapia en el tratamiento de la hipertensión arterial, así como esclarecer los mecanismos a través de los cuales reduce la presión sanguínea. Se encontró que en la genesis de la hipertensión arterial intervienen lesiones por plenitud calurosa, o exceso de Yang de hígado, y por calor por vacío, o deficiencia del Yin de riñón. El efecto corrector de la auriculoterapia sobre la hipertensión arterial se explica a través de mecanismos neurológicos, humorales y bioeléctricos que producen sedación, vasodilatación, diuresis e hipotensión; entre los puntos de la auriculopuntura más utilizados en el tratamiento de la hipertensión arterial se incluyen: shenmen auricular, hipertensión arterial 1 y 2, corazón e hígado.

    Full Text Available En este estudio se analiza la anatomía, estructura y desarrollo de los frutos en 12 especies de Piriqueta y 30 especies de Turnera; con el objetivo de identificar la estructura involucrada en la dehiscencia y verificar la existencia de patrones en la organización del fruto entre las especies analizadas. El ovario es sincárpico, tricarpelar, unilocular con placentación parietal, presentando la misma estructura en todas las especies. Ambas epidermis carpelares son uniestratificadas y tienen estomas, el mesófilo es parenquimático con 3 haces dorsales y 3 marginales. Durante el desarrollo del fruto, la epidermis externa forma un epicarpo papiloso en las especies de Piriqueta. El mesocarpio deriva de los estratos medios del ovario, formando un estrato mecánico de braquiesclereidas. Estas esclereidas pueden organizarse como un cilindro continuo determinando frutos de superficie lisa o agruparse en nidos, unidos o no, determinando así frutos granulares, verrugosos, o tuberculados. Las cápsulas son loculicidas, con línea de dehiscencia formada por macroesclereidas dispuestas longitudinalmente en el fruto, paralelas al haz carpelar dorsal. Se concluye que los diferentes tipos de pericarpio son un rasgo post-fecundación, dado que la estructura del ovario es exactamente la misma en todas las especies analizadas. Se analiza la anatomía del fruto en relación al esquema taxonómico actualizado.The aims of this work were to describe the morphology, anatomy and development of the fruits of 12 species of Piriqueta and 30 species of Turnera; to identify the structures related to the process of dehiscence of the capsule; and to verify the occurrence of standards carpological structure between the studied species.

En los países industrializados, la causa más frecuente de muerte súbita cardíaca (MSC en el adulto es la isquemia miocárdica aguda por arterioesclerosis coronaria. Sin embargo, existen otras patologías coronarias, congénitas o adquiridas, que pueden producir isquemia miocárdica y muerte súbita: origen anómalo, hipoplasia, estenosis del ostium, aneurisma, disección, localización alta del ostium, puente miocárdico, vasculitis. El objetivo del presente trabajo es revisar la casuística de este tipo de patología coronaria no arterioesclerótica en las 8003 autopsias realizadas en el Instituto de Medicina Legal de Valencia (IMLV entre los años 1997-2005. Método: Los criterios de inclusión de los casos para este estudio han sido: edad superior a 14 años, patología coronaria no arterioesclerótica como causa de muerte y circunstancias de la muerte compatibles con la definición de muerte súbita. Resultados: Se han encontrado 9 casos de muerte súbita en adultos con patología coronaria no arterioesclerótica como causa de muerte: 2 casos de puente miocárdico, 6 casos de disección coronaria y 1 caso de origen anómalo de coronaria. Conclusiones: La patología coronaria no arterioesclerótica, aunque es poco frecuente como causa de MSC, debemos conocerla y poder diagnosticarla macroscópicamente en la sala de autopsias. Siempre debe descartarse otra posible causa de muerte mediante los estudios complementarios químico-toxicológicos e histopatológicos. Es importante conseguir la máxima información clínica anterior al fallecimiento que pueda ayudar al diagnóstico en vida de este tipo de patologías, ya que en la mayoría de los casos sigue siendo un hallazgo postmortem.Introduction and objectives.

    Full Text Available En vista que las evidencias obtenidas acerca del beneticio percibido por los sujetos hipertensos leves con los tratamientos farmacológicos resultan conflictivas, se ha considerado importante para estos pacientes, la aplicación de intervenciones psicológicas y comportamentales. Se presentan en este trabajo, distintos tipos de tratamientos psicológicos que en los últimos años han demostrado su efectividad en la reducción de la presión arterial esencial. Se consideraron importantes para individuos hipertensos leves, la implementación de procedimientos tales como: la relajación, el entrenamiento autógeno, la retroalimentación biológica, la meditación, el Hatha -Yoga, la reestructuración cognitiva y el entrenamiento en habilidades sociales, porque contribuyeron a la reducción, no solo de los niveles hipertensivos sino también de los efectos adversos de la medicación farmacológica que afectan la calidad de vida. Es necesario evidentemente que el individuo generalice las estrategias aprendidas en el contexto clínico-experimental, a los diferentes contextos vitales. La técnica empleada, las características del terapeuta y el tipo de personalidad del paciente son componentes principales en la determinación del éxito del tratamiento. La práctica diaria sostenida fuera del contexto clínico, es un elemento de crucial importancia para el mantenimiento de la mejoría lograda.

  2. ADAPTACIÓN DEL ALGORITMO MARACAS PARA SEGMENTACIÓN DE LA ARTERIA CARÓTIDA Y CUANTIFICACIÓN DE ESTENOSIS EN IMÁGENES TAC Adaptation of the MARACAS Algorithm for Carotid Artery Segmentation and Stenosis Quantification on CT Images

    MARIA A ZULUAGA

    Full Text Available En este artículo se describen las adaptaciones hechas al algoritmo MARACAS para segmentar y cuantificar estructuras vasculares en imágenes TAC de la arteria carótida. El algoritmo MARACAS, que está basado en un modelo elástico y en un análisis de los valores y vectores propios de la matriz de inercia, fue inicialmente diseñado para segmentar una sola arteria en imágenes ARM. Las modificaciones están principalmente enfocadas a tratar las especificidades de las imágenes TAC, así como la presencia de bifurcaciones. Los algoritmos implementados en esta nueva versión se clasifican en dos niveles. 1. Los procesamientos de bajo nivel (filtrado de ruido y de artificios direccionales, presegmentación y realce destinados a mejorar la calidad de la imagen y presegmentarla. Estas técnicas están basadas en información a priori sobre el ruido, los artificios y los intervalos típicos de niveles de gris del lumen, del fondo y de las calcificaciones. 2. Los procesamientos de alto nivel para extraer la línea central de la arteria, segmentar el lumen y cuantificar la estenosis. A este nivel, se aplican conocimientos a priori sobre la forma y anatomía de las estructuras vasculares. El método fue evaluado en 31 imágenes suministradas en el concurso Carotid Lumen Segmentation and Stenosis Grading Grand Challenge 2009. Los resultados obtenidos en la segmentación arrojaron un coeficiente de similitud de Dice promedio de 80,4% comparado con la segmentación de referencia, y el error promedio de la cuantificación de estenosis fue 14,4%.This paper describes the adaptations of MARACAS algorithm to the segmentation and quantification of vascular structures in CTA images of the carotid artery. The MARACAS algorithm, which is based on an elastic model and on a multi-scale eigen-analysis of the inertia matrix, was originally designed to segment a single artery in MRA images. The modifications are primarily aimed at addressing the specificities of CT

    Full Text Available Abstract A coronary arterial fistula is a connection between one or more of the coronary arteries and a cardiac chamber or great vessel. This is a rare defect and usually occurs in isolation. Its exact incidence is unknown. The majority of these fistulas are congenital in origin although they may occasionally be detected after cardiac surgery. They do not usually cause symptoms or complications in the first two decades, especially when small. After this age, the frequency of both symptoms and complications increases. Complications include 'steal' from the adjacent myocardium, thrombosis and embolism, cardiac failure, atrial fibrillation, rupture, endocarditis/endarteritis and arrhythmias. Thrombosis within the fistula is rare but may cause acute myocardial infarction, paroxysmal atrial fibrillation and ventricular arrhythmias. Spontaneous rupture of the aneurysmal fistula causing haemopericardium has also been reported. The main differential diagnosis is patent arterial duct, although other congenital arteriovenous shunts need to be excluded. Whilst two-dimensional echocardiography helps to differentiate between the different shunts, coronary angiography is the main diagnostic tool for the delineation of the anatomy. Surgery was the traditional method of treatment but nowadays catheter closure is recommended using a variety of closure devices, such as coils, or other devices. With the catheter technique, the results are excellent with infrequent complications. Disease name and synonyms Coronary arterial fistulas Coronary arterial fistulas or malformations

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

Carotid artery stenting (CAS) is a therapy that is established for many years. CAS reveals complication rates and long-term efficacy comparable to carotid endarterectomy (TEA). Especially younger patients seem to benefit from CAS. Abilities and experiences of the therapist and the choice of the techniques used are critical for patient safety. The efficacy of CAS for treatment of asymptomatic carotid stenosis is probable but still unproven in prospective-randomized trial. (orig.)

    LENUS (Irish Health Repository)

    Boutouyrie, Pierre

    2011-09-10

    Arterial stiffness has emerged as an important marker of cardiovascular risk in various populations and reflects the cumulative effect of cardiovascular risk factors on large arteries, which in turn is modulated by genetic background. Arterial stiffness is determined by the composition of the arterial wall and the arrangement of these components, and can be studied in humans non-invasively. Age and distending pressure are two major factors influencing large artery stiffness. Change in arterial stiffness with drugs is an important endpoint in clinical trials, although evidence for arterial stiffness as a therapeutic target still needs to be confirmed. Drugs that independently affect arterial stiffness include antihypertensive drugs, mostly blockers of the renin-angiotensin-aldosterone system, hormone replacement therapy and some antidiabetic drugs such as glitazones. While the quest continues for \\'de-stiffening drugs\\

Con base en antropología interpretativa, los datos fueron reunidos en informes narrativos y analizados por medio de la a elaboración de unidades de significados y núcleos temáticos. RESULTADOS:Los sentidos atribuidos a la enfermedad se relacionaron a: descubierta de la enfermedad cardiaca, sentimientos desencadenados, explicaciones formuladas, aceptación de la cirugía y vida pos-cirurgica. La experiencia fue interpretada como ruptura biográfica, situación entre la vida y la muerte, invalidez, perdida de autonomía e incapacidad de trabajar. Los significados se remitieron a una lógica que articula sentido común, religión y fragmentos del discurso médico en la comprensión de la enfermedad y de la cirugía cardiaca. CONCLUSIONES: Los resultados rebelan que las experiencias de la enfermedad y de la cirugía cardíaca marcan una ruptura en el modo de vivir, trabajar y comprender el proceso salud-enfermedad. La abordaje de la experiencia de la enfermedad cardiaca contribuye para extrapolar los límites de un modelo centrado en la enfermedad, sus síntomas y causas, característico del entendimiento biomédico del proceso salud-enfermedad, cuyo foco es el mal funcionamiento del proceso biológico y/o psicológico.OBJECTIVE:To evaluate the meanings of heart disease experience in patients undergoing rehabilitation post-coronary artery bypass grafting surgery.

    Summary The trigeminal artery is an anastomosis between the embryonic precursors of the vertebrobasilar and carotid systems, and may persist into adult life. The association of the persistent primitive trigeminal artery (PTA) with cerebral aneurysm is well documented in the literature and, in general, aneurysms are located in the anterior circulation. We describe a patient who presented with a panencephalic Fisher III subarachnoid hemorrhage due to rupture of an intracranial aneurysm. Digital arteriography showed a saccular aneurysm in the middle third of the basilar artery, adjacent to the junction with a persistent trigeminal artery. She was submitted to endovascular treatment with embolization of the basilar artery aneurysm with coils. Aneurysms at the PTA junction with the basilar artery are rare. This paper describes a case of PTA associated with an aneurysm in the basilar artery at PTA junction and briefly reviews the literature. PMID:22005697

Combined computed tomography and myocardial perfusion scanning identified an anomalous dominant right coronary artery that appeared kinked at its origin between the aorta and main pulmonary artery. A robot-assisted right internal thoracic artery to right coronary artery bypass was performed, which was confirmed to be widely patent (FitzGibbon grade A) on routine intraoperative angiography. The procedure completely resolved the patient's angina symptoms. PMID:20931103

    Full Text Available A propósito de un caso de reblandecimiento limitado al territorio arterial anterior y mediano del bulbo que se traducía, clínicamente, por una hemiplejía controlateral con trastornos sensitivos y ausencia de compromiso del facial o de la lengua, y del análisis de 8 casos anatomo-clínicos encontrados en una revisión bibliográfica, los autores discuten el problema de la irrigación arterial del bulbo, el cuadro clínico y el tan debatido asunto de la pretendida flaccidez de estas hemiplejias. Desde el punto de vista de la vascularización arterial del bulbo, se insiste en que ésta es compleja y variable según que se trate del sector oral contiguo a la protuberancia, del sector caudal contiguo a la médula o del sector intermediario a los dos. Desde el punto de vista clínico, en los casos típicos, se trata de una hemiplejia espástica con trastornos sensitivos sin compromiso del facial, ni del hipogloso. De los nueve casos anatomo-clínicos registrados hasta el presente, seis con larga sobrevida, presentaron hemiplejia espástica; dos, con sobrevidas cortas, se encontraban en la etapa de transición hacia la espasticidad; uno con lesiones extensas presentó una flaccidez permanente. En lo que se refiere al problema de la pretendida flaccidez de estas hemiplejias vemos que las hemiplejías bulbares no escapan a la regla de las lesiones del haz piramidal, las que después de una primera etapa de flaccidez evolucionan hacia la espasticidad. Por tanto las conclusiones doctrinarias referentes al haz piramidal basadas en ésta pretendida flaccidez de la hemiplejía bulbar son erróneas y deben revisarse.

    The superficial temporal artery has been thought to be the main focus of pain during migraine attacks, but its diameter has never been measured directly. The use of a new, high-resolution ultrasound machine to measure arterial size in 25 migraine patients with unilateral head pain showed that the...... lumen was wider on the painful than on the non-painful side during a migraine attack. The diameters of both radial arteries and the temporal artery on the non-painful side were smaller during than between attacks.

    True upper extremity peripheral artery aneurysms are a rarely encountered arterial disorder. Following computer-tomography angiographic (CT-a) imaging examination, true saccular aneurysm, originating from the left brachial artery was diagnosed in the 77-year-old female without history of trauma. The aneurysm was resected by surgical intervention, and primary repair of the brachial artery was performed by interposition of a part of great saphenous vein harvested from the left groin and creation of two end-to-end anastomoses between interposition graft and previously resected part of brachial artery. No complication was observed during the follow-up. Surgical intervention for upper extremity aneurysms should be initiated without delay. Factors combined with minimal morbidity associated with repair suggest that surgical repair should be performed routinely for true upper extremity arterial aneurysms. PMID:20865459

    International Nuclear Information System (INIS)

    A 39-year-old healthy man had several transient ischaemic attacks suggesting left internal carotid artery (ICA) occlusion. There were no vascular risk factors and no preceding trauma. Colour-coded duplex sonography suggested a pseudo-occlusion of the left ICA, and cerebral angiography demonstrated dissection of the left ICA and both vertebral arteries. Angiography 6 months later was completely normal. This underlines the importance of four vessel angiography in young patients with dissections of cervical arteries. (orig.)

    Various benign and malignant conditions could cause biliary obstruction. Compression of extrahepatic bile duct (EBD) by right hepatic artery was reported as a right hepatic artery syndrome but all cases were compressed EBD from stomach side. Our case compressed from dorsum was not yet reported, so it was thought to be a very rare case. We present here the first case of bile duct obstruction due to the compression of EBD from dorsum by right hepatic artery.

    International Nuclear Information System (INIS)

    A bibliographic review is realized in the arterial mapping of lower limbs by ultrasonographic. The physical properties of the Doppler effect applied to diagnostic ultrasound are described. The anatomical characteristics of the general arterial system and specifically of the lower limbs arterial system are mentioned. Pathologies of the ischemic arterial disease of lower limbs are explained. The study characteristics of lower limbs arterial mapping are documented to determine its importance as appropriate method for the assessment of lower limb ischemia. An adequate arterial mapping of lower limbs is recognized in atherosclerotic ischemic disease as a reliable initial method alternative to arteriography. Arteriography is considered as reference pattern for therapeutic decision making in patients with critical ischemia of the lower limbs. Non-invasive methods to assess the arterial system of lower limbs has evidenced the advantages of the arterial mapping with Doppler, according to the consulted literature. The combination morphological and hemodynamic information has been possible and a map of the explored zone is made. The arterial mapping by ultrasonography has offered similar reliability to angiography

    Single coronary artery is a fairly rare entity which may nevertheless be found in 0.4 per cent of coronary arteriograms. The authors report 3 cases seen in 2 departments of cardiology. In each patient, despite the existence of definite cardiovascular risk factors, this distribution was a factor worsening coronary ischemia, leading to complete thrombosis in one case. Although most often a chance discovery, a review of the literature justifies the attribution to this anomaly of the onset of angina, infarction or even sudden death. PMID:1642437

    Carotid artery dissection is an important cause of ischemic stroke in all age groups, particularly in young patients. The purpose of this work was to assess whether there is an association between the presence of an internal carotid artery dissection (ICAD) and the arterial tortuosity. This study considered 124 patients (72 males and 52 females; median age 57 years) with CT/MR diagnosis of ICAD of the internal carotid artery were considered in this multi-centric retrospective study. The arterial tortuosity was evaluated and, when present, was categorized as elongation, kinking, or coiling. For each patient, both the right and left sides were considered for a total number of 248 arteries in order to have the same number of cases and controls. Fisher's exact test was applied to test the association between elongation, kinking, coiling, dissection, and the side affected by CAD. Fisher's exact test showed a statistically significant association between the ICAD and kinking (p = 0.0089) and coiling (p = 0.0251) whereas no statistically significant difference was found with arterial vessel elongation (p = 0.444). ICAD was more often seen on the left side compared to the right (p = 0.0001). These results were confirmed using both carotid arteries of the same patient as dependent parameter with p = 0.0012, 0.0129, and 0.3323 for kinking, coiling, and elongation, respectively. The presence of kinking and coiling is associated with ICAD. (orig.)

    Background— Bilateral internal thoracic arteries (BITA) have demonstrated superior patency and improved survival in patients undergoing coronary artery bypass grafting. However, the optimal configuration for BITA utilization and its effect on long-term outcome remains uncertain. Methods and Results— We randomly assigned 304 patients undergoing coronary artery bypass grafting using BITA to either in situ or Y grafting configurations. The primary end point was 3-year angiographic patency. Secondary end points included major adverse cardiac and cerebrovascular events (ie, death from any cause, stroke, myocardial infarction, or repeat revascularization) at 7 years. More coronary targets were able to be revascularized using internal thoracic arteries in patients randomized to Y grafting versus in situ group (3.2±0.8 versus 2.4±0.5 arteries/patient; PURL: http://www.clinicaltrials.gov.

  6. Thoracodorsal artery examination with doppler ultrasound in healthy volunteers in a level three hospital

    International Nuclear Information System (INIS)

    Introduction: The thoracodorsal artery is a branch of the subscapular artery, which in turn is a branch of the axillary artery. The importance of this artery is that it supplies the latissimus dorsi muscle, used as a muscle-skin flap for breast reconstruction after mastectomy, mainly in patients with poor local tissues, in particular after receiving radiotherapy. Objective: to describe the physical characteristics of the thoracodorsal artery using Doppler ultrasound evaluation in healthy volunteers at Hospital Universitario del Valle. Materials and methods: We conducted a descriptive pilot study, because, after reviewing the medical literature, we did not find any reports assessing the thoracodorsal artery with the use of Doppler ultrasound. Results: we evaluated 51 patients, 50.9% female. The average age of the patients was 28.78 years. the axillary, subscapular and thoracodorsal arteries were identified in all patients. The characteristics of the thoracodorsal artery were as follows: Diameter 1.88 mm, peak systolic velocity 28.45 cm/s, peak diastolic velocity 2.03 cm/s, resistance index 0.94, pulsatility index 4.02. Although the study did not include anthropometric measurements, we found that the artery was more conspicuous in patients with developed muscle mass and in patients with low adiposity. Conclusions: The thoracodorsal artery was identified in all patients, and ultrasound localization is a procedure that is easy to perform and provides vital information about the presence of the vascular pedicle required to perform a latissimus dorsi muscle-skin flap. Additional studies in post mastectomy patients are required in order to assess postoperative changes associated with the presence and physical characteristics of the thoracodorsal artery.

Clinical findings and complementary studies suggested a bilateral atherogenic embolic event. Initially, she presented a superior branch retinal artery occlusion in her right eye followed by a central retinal artery occlusion with cilioretinal artery sparing in her left eye. Some conservative maneuvers performed did not improve visual acuity in the left eye. Supra-aortic Doppler ultrasonography revealed mild right internal carotid artery stenosis and moderate left internal carotid artery stenosis with a small, smooth, and homogeneous plaque. The transthoracic echocardiography showed a severe calcification of the mitral valve with a mild-moderate rim of stenosis. Central retinal artery occlusion and branch retinal artery occlusion are characterized by painless monocular loss of vision. Clinical approach and management attempt to treat the acute event, find the source of the vascular occlusion, and prevent further vascular events from occurring. Giant cell arteritis is a potentially treatable cause of central retinal artery occlusion and should be excluded in every single patient over 50 years old.Keywords: loss of vision, branch retinal artery occlusion, central retinal artery occlusion, Hollenhorst plaque

    Full Text Available Abstract Patent arterial duct (PAD is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes. Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of

    Three kinds of carotid-basilar anastomosis have been found, they were named as persistent primitive trigeminal artery, persistent primitive acoustic (or otic) artery and persistent primitive hypoglossal artery, among them, the persistent primitive hypoglossal artery is by far the least common type of the internal carotid-basilar anastomosis which have been demonstrate in human postembryonic stages. Persistent primitive by hypoglossal artery is usually found incidentally. This vascular anomaly, however,have been reported to be associated with multiple congenital anomalies, such as unilateral or bilateral vertebral artery hypoplasia, absence of the posterior communicating artery, hypoplasia of the proximal portion of the posterior cerebral artery, aneurysm of the circle of Willis, the origin of both pericallosal arteries from a single anterior cerebral artery, retarded mental development dating from infancy, carotid-cavernous fistula formation etc. A case of persistent primitive hypoglossal artery in an young Korean male was reported with brief review of the literature.

    2016-07-01

    Spontaneous coronary artery dissection is an important etiology of nonatherosclerotic acute coronary syndrome, myocardial infarction, and sudden death. Innovations in the catheterization laboratory including optical coherence tomography and intravascular ultrasound have enhanced the ability to visualize intimal disruption and intramural hematoma associated with SCAD. Formerly considered "rare," these technological advances and heightened awareness suggest that SCAD is more prevalent than prior estimates. SCAD is associated with female sex, young age, extreme emotional stress, or extreme exertion, pregnancy, and fibromuscular dysplasia. The clinical characteristics and management strategies of SCAD patients are different than for atherosclerotic heart disease and deserve specific consideration. This review will highlight recent discoveries about SCAD as well as describe current efforts to elucidate remaining gaps in knowledge. PMID:27216840

    Twenty-one femoropopliteal percutaneous transluminal atherectomies were performed with the Simpson catheter. Evaluation included clinical examination, Doppler ultrasonography (ankle-arm index, before and immediately and 1,3 and 6 months after atherectomy), and angiography (6 months after or for clinical worsening). Twenty of 21 procedures achieved satisfactory vessel patency, with the addition of complementary angioplasty for residual stenosis over 30% (one of three cases). Early thrombosis occurred in only one of 21 cases (absence of platelet inhibitor pretherapy), and no distal embolization occurred. Six-month follow-up showed stable improvements in 11 of 12 patients and restenosis in only one (absence of platelet inhibitor pretherapy). Preliminary results indicate that atherectomy is the method of choice for restoring large lumens, with minimal arterial wall injury and fewer cases of restenosis than with angioplasty

    To find and describe the cerebellar arteries arising from the internal carotid artery, explain them embryologically, and evaluate their clinical implication. To determine the point in the internal carotid artery from which the cereballar artery arose anomalously, consecutive angiographic studies performed in the last three years were reviewed. The distribution of such anomalous cerebellar arteries, the point in the internal carotid artery from which the anomalous vessels originated, and associated findings were analyzed. Five anomalous origins of cerebellar arteries arising arising directly from the internal carotid artery were found in five patients. Three anterior inferior cerebellar arteries (AICA) and one common trunk of an AICA and a posterior inferior cerebellar artery (PICA) were found to originate from the internal carotid artery at a point close to the origin of the primitive trigeminal artery. A PICA arose from an artery presenting a course similar to the proatlantal intersegmental artery. Intracranial aneurysms in two patients, Moyamoya disease in one, and facial arteriovenous malformation in one. In our series, AICAs supplied from the arteries considered to be persistent trigeminal artery variants were the most common type. A correlation between type of anomalous cerebellar artery and type of carotid-vertebrobasilar anastomosis may exist. Cerebellar arteries originating anomalously from the internal carotid artery seem to occur as a result of the persistence of carotid-vertebrobasilar anastomoses associated with incomplete fusion of the longitudinal neural arteries. An understanding of these anomalous cerebellar arteries may help prevent accidents during therapeutic embolization and surgical treatment, as well as misinterpretation.

    Full Text Available Background: The proper knowledge of the course and ramification of blood vessels of lower limbs is very important for surgeons and interventional radiologist. Medial circumflex femoral artery usually originates from posteromedial aspect of the profunda femoris, but often originates from femoral artery itself. It has an important role in supplying blood to femoral neck and head, fatty tissue in acetabular fossa and used in flaps reconstructive surgery. Methods: 50 adult lowerlimbs were procured from embalmed cadavers of J.J.M. Medical College and S.S.I.M.S & R.C, Davangere, Karnataka, India for the study. Dissection of femoral triangle was carried out according to Cunningham’s manual. Site and mode of origin of the branches of femoral artery were studied, configuration of the femoral origins of medial and lateral circumflex femoral artery and their prevalence were studied. Results: Out of 50 extremities, Medial circumflex femoral artery took origin from profunda femoris in 41 specimens and from femoral artery in 9 specimens. Conclusion: The knowledge of normal origin and variation of medial circumflex femoral artery is very valuable in preventing iatrogenic injury to these vessels during surgical procedures of femoral triangle.

    Intra-arterial infusion of chemotherapy into the ophthalmic artery for treatment of retinoblastoma has been realized after catheterization of the internal carotid and temporary balloon occlusion beyond the orifice of the ophthalmic artery, or more recently after superselective canulation of the ophthalmic artery by a microcatheter. The superselective catheterization of the ophthalmic artery could be cumbersome because of the implantation of the ostium on the carotid siphon or because of the tortuosity of the carotid siphon. We report our experience of using a retrograde approach through the posterior communicating artery that allows a more direct angle of access to the origin of the ophthalmic artery. (orig.)

    Full Text Available Atherosclerosis is a chronic slow-developing condition affecting medium-size and large blood vessels. It is the principal underlying pathology of coronary heart disease and stroke. In some countries, coronary artery disease (CAD is the cause of nearly half (48% of the deaths and, loss of productivity life. Peripheral arterial disease (PAD is defined as atherosclerosis in peripheral arteries instead of coronary arteries. CAD and PAD have same risk factors and underlying pathophysiological processes. Therefore, patient with CAD should be considered for PAD. Ankle brachial index (ABI, duplex sonography, and some other non-invasive techniques are recommended for PAD diagnosis in patients with the history of CAD. Pharmacotherapy, endovascular interventions, and surgical management could be chosen according to the patient’s situation. Cardiologists and general practitioners should consider PAD in a patient with CAD or DM as a strong correlated disease.

    The prevalence of peripheral vascular disease in patients with coronary artery disease has been investigated in many different ways and depends on the diagnostic methods and the definition of the atherosclerotic manifestations in the different vascular beds. In this study we used the non-invasive methods digital volume pulse plethysmography and ankle and toe blood pressure measurements to identify arterial abnormalities in the lower limbs in 58 patients (49 males and 9 females; age 37-72 years) examined with coronary angiography. The prevalence of peripheral artery disease was 22%, in agreement with the results of most previous investigations. There was a tendency towards increasing prevalence of peripheral artery disease with more advanced coronary artery disease: 14% of the patients with no or minimal coronary atheromotous lesions, 18% of the patients with moderate coronary atheromotous lesions and 32% of the patients with marked coronary atheromotous disease. For this reason a non-invasive investigation of the peripheral arterial circulation should be included early in the clinical consideration of patients with chest pain or similar symptoms suggesting coronary heart disease. Toe pressure measurement appears to be the most appropriate technique being rather simple in management and also in evaluation of results. PMID:7658111

    Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point (California, USA) revised previous classifications. Currently, PH is devided into five subgroups. Group 1 includes patients suffering from idiopathic or familial PAH with or without germline mutations. Patients with a diagnosis of PAH should systematically been screened regarding to underlying mutations of BMPR2 gene (bone morphogenetic protein receptor type 2) or more rarely of ACVRL1 (activine receptor-like kinase type 1), ENG (endogline) or Smad8 genes. Pulmonary veno occusive disease and pulmonary capillary hemagiomatosis are individualized and designated as clinical group 1'. Group 2 'Pulmonary hypertension due to left heart diseases' is divided into three sub-groups: systolic dysfonction, diastolic dysfonction and valvular dysfonction. Group 3 'Pulmonary hypertension due to respiratory diseases' includes a heterogenous subgroup of respiratory diseases like PH due to pulmonary fibrosis, COPD, lung emphysema or interstitial lung disease for exemple. Group 4 includes chronic thromboembolic pulmonary hypertension without any distinction of proximal or distal forms. Group 5 regroup PH patients with unclear multifactorial mechanisms. Invasive hemodynamic assessment with right heart catheterization is requested to confirm the definite diagnosis of PH showing a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg and a normal pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg. The assessment of PCWP may allow the distinction between pre-capillary and post-capillary PH (PCWP > 15 mmHg). Echocardiography is an important tool in the management of patients with underlying suspicion of PH. The European Society of Cardiology and the European Respiratory Society (ESC-ERS) guidelines specify its role

    Four cases of irradiation injury to large arteries following radiotherapy treatment are presented and the literature is reviewed. Three patterns of injury have emerged: 1) intimal damage resulting in mural thrombosis presenting within 5 years of irradiation, 2) fibrotic occlusion presenting within 10 years of injury, and 3) a predisposition to the development of atheroma together with periarterial fibrosis associated with a latent interval of 20 or more years. The treatment of choice is a bypass procedure of the arterial lesion. (author)

  16. Liver cirrhosis and arterial hypertension

    Characteristic findings in patients with cirrhosis are vasodilatation with low overall systemic vascular resistance, high arterial compliance, increased cardiac output, secondary activation of counter-regulatory systems (renin-angiotensin-aldosterone system,sympathetic nervous system, release of vasopressin),and resistance to vasopressors. The vasodilatory state is mediated through adrenomedullin, calcitonin generelated peptide, nitric oxide, and other vasodilators,and is most pronounced in the splanchnic area.This constitutes an effective (although relative)counterbalance to increased arterial blood pressure.This review considers the alterations in systemic hemodynamics in patients with cirrhosis in relation to essential hypertension and arterial hypertension of the renal origin. Subjects with arterial hypertension (essential, secondary) may become normotensive during the development of cirrhosis, and arterial hypertension is rarely manifested in patients with cirrhosis, even in cases with renovascular disease and high circulating renin activity. There is much dispute as to the understanding of homoeostatic regulation in cirrhotic patients with manifest arterial hypertension. This most likely includes the combination of vasodilatation and vasoconstriction in parallel.

However, studies of arterial function in vegetarians are limited.Methods: This study investigated arterial function in vegetarianism by comparing 49 healthy postmenopausal vegetarians with 41 age-matched omnivores. The arterial function of the common carotid artery was assessed by carotid duplex, while the pulse dynamics method was used to measure brachial artery distensibility (BAD, compliance (BAC, and resistance (BAR. Fasting blood levels of glucose, lipids, lipoprotein (a, high-sensitivity C-reactive protein, homocysteine, and vitamin B12 were also measured.Results: Vegetarians had significantly lower serum cholesterol, high-density and low-density lipoprotein, and glucose compared with omnivores. They also had lower vitamin B12 but higher homocysteine levels. Serum levels of lipoprotein (a and high-sensitivity C-reactive protein were no different between the two groups. There were no significant differences in carotid beta stiffness index, BAC, and BAD between the two groups even after adjustment for associated covariates. However, BAR was significantly lower in vegetarians than in omnivores. Multiple linear regression analysis revealed that age and pulse pressure were two important determinants of carotid beta stiffness index and BAD. Vegetarianism is not associated with better arterial elasticity.Conclusion: Apparently healthy postmenopausal vegetarians are not significantly better in terms of carotid beta stiffness index, BAC, and BAD, but have significantly decreased BAR than

     Vascular anatomy of the liver is varied, and the"standard"anatomy is seen in 55%-80%of cases. It is very important that extrahepatic arteries are identiifed precisely at the time of graft procurement to avoid injuries that might compromise the liver function. In the present case the liver donor had the vascular anatomy of Michels type Ⅶ, e.g. a hepatic artery originating from the celiac trunk and going to the left lobe, an accessory left hepatic artery coming from the left gastric artery, and a replaced right hepatic artery coming from the superior mesenteric artery. This pattern of vascular supply is uncommon, representing less than 5%of cases. The replaced hepatic artery was reconstructed in the back-table with polypropylene suture 7.0 by connecting it to the stump of the splenic artery, and the celiac trunk of the graft was anastomosed to the recipient common hepatic artery.

    Full Text Available Occurrence of a median cubital arterial arch is very rare. We saw a superficially placed median cubital arterial arch associated with high level of origin of radial artery. The radial artery took origin from the brachial artery in the upper third of the arm and crossed median nerve and ulnar artery from medial to lateral side. The course and distribution of the vessels in the forearm was normal. In the cubital fossa, the radial and ulnar arteries were connected to each other by an arterial arch. The variations reported here are very useful for the radiologists as these variations can cause problems in invasive procedures.

    Full Text Available Basilar artery thrombosis has high morbidity and mortality. Though intra-arterial thrombolytics have proven efficacy in the treatment of acute basilar artery occlusion, the elevation of procoagulant factors in the blood after intra-arterial thrombolysis could result in subsequent thrombus formation and clinical deterioration. Glycoprotein IIb/IIIa inhibitors have been shown to reduce this elevation in procoagulants. We present a pilot study of three cases of acute basilar artery occlusion treated with a combination of intra-arterial thrombolytics and Gp IIb/IIIa inhibitor with remarkable clinical recovery seen in all the patients.

    The principal aim of this investigation was to study the anual morpho-histological changes in the ovary of the fish capitan, Eremophilus mutisii, in the Rio Bogota basin in Colombia, with regard to the reproductive cycle, size of the mature fishes and seasonal changes in the environment. The fibs material was collected monthly. The gonads were fixed in Bouin's fixative. Subsequently they were washed several times in 70% ethanol. Transversal sections of about 5 cm in length, each of which produced 10 slides with 10 or so sections per slide, were taken from the center to the anterior portion of the right ovary of each fish, since no macroscopic significant differencie was observed in the oogenic process in the anterior, central and posterior portion of the ovary. The sections were dehydrated in tetrahydrofuran and embedded in paraffin. Sections were cut at 6 microns and stained with haematoxylin and eosin (H & E. The gonosomatic index (GSI or maturity index (MIl was calculated.

    Full Text Available La familia de protooncogenes MYC (c-Myc, N-Myc y L-Myc se relaciona con el origen de diversas neoplasias en seres humanos. Estos genes actúan como factores de transcripción y participan en la regulación del ciclo celular, la proliferación y diferenciación celulares, la apoptosis y la inmortalización. Los genes MYC se expresan en diferentes tejidos y responden a diversas señales internas y externas; codifican para la síntesis de factores de transcripción que se unen al ADN para regular la expresión de múltiples genes. El gen más ampliamente estudiado de esta familia es c-Myc, que se expresa en las células con mayor tasa de proli­feración. C-Myc se encuentra alterado en un gran número de tumores sólidos, leucemias y linfomas. Las alteraciones de c-Myc encontradas con mayor frecuencia en células cancero­sas son las amplificaciones, translocaciones, mutaciones y reordenamientos cromosómicos que involucran el locus de este gen y conducen a que se desregule su expresión en diversas neoplasias humanas. La amplificación de c-Myc es una alteración común en los cánceres de mama, pulmón, ovario y próstata, así como en leucemias y linfomas, mientras que la pérdida de su regulación es común en el cáncer de colon, en tumores ginecológicos y melanoma. En neoplasias con defectos de c-Myc los estudios actuales están dirigidos al desarrollo de nuevas estrategias terapéuticas.

    A persistent trigeminal artery (PTA) is the most common carotid-vertebrobasilar anastomosis, usually arising from the cavernous or precavernous segment of the internal carotid artery (ICA) and connecting to the distal basilar artery. There are two types of PTA, lateral and medial. We present the first case of a lateral-type PTA arising from the large arterial ring/fenestration of the cavernous segment of the left ICA with findings from both magnetic resonance angiography and selective catheter angiography.

    The trigeminal artery is the largest of the fetal carotid-basilar anastomotic arteries, and it persists for the longest embryonic period. The artery usually involutes after the development of the posterior communicating artery. The exact causes of persistence of this primitive vessel into adulthood are not completely clear. Angiographic and anatomical descriptions of the various persistent trigeminal artery (PTA) configurations and their relation to the remainder of the cerebrovascular tree and the other surrounding structures have been reported. Persistent trigeminal artery can be associated with many other vascular anomalies and disorders including aneurysms, arteriovenous malformations and carotid-cavernous fistulae. A thorough understanding of the anatomical and angiographic features of this persistent embryonic arterial channel is of utmost importance when making therapeutic decisions and embarking on surgical or endovascular intervention for any pertinent pathological condition. We review the embryology, angiographic features, microsurgical anatomy and associated vascular anomalies and disorders of the persistent trigeminal artery. PMID:22843453

    Full Text Available Vertebral artery arises from the upper surface of the first part of subclavian artery on both sides. The morphological variations of the vertebral artery are of immense importance in surgery, angiography and all non-invasive procedures. During the routine dissection of a male cadaver aged about 65 years, we observed a variation in the branching of arch of aorta. The arch of aorta gave off four branches-brachiocephalic trunk, left common carotid artery (CCA, left vertebral artery (LVA and left subclavian artery. LVA was arising between left CCA and left subclavian artery.The knowledge of variations in the vertebral artery is of great clinical interest to the neurosurgeon and radiologist for diagnostic investigation and surgical procedures of the neck.

    Throughout its 30-year history, the right gastroepiploic artery (GEA) has been useful for in situ grafts in coronary artery bypass grafting (CABG). The early graft patency rate is high, and the late patency rate has improved by using the skeletonized GEA graft and proper target selection, which involves having a target coronary artery with a tight >90% stenosis. Total arterial revascularization with the internal thoracic artery and GEA grafts is an option for achieving better outcomes from CABG procedures. PMID:27525230

  4. Determination of arterial wall shear stress

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The arteries can remodel their structure and function to adapt themselves to the mechanical environment. In various factors that lead to vascular remodeling, the shear stress on the arterial wall induced by the blood flow is of great importance. However, there are many technique difficulties in measuring the wall shear stress directly at present. In this paper, through analyzing the pulsatile blood flow in arteries, a method has been proposed that can determine the wall shear stress quantitatively by measuring the velocity on the arterial axis, and that provides a necessary means to discuss the influence of arterial wall shear stress on vascular remodeling.

No inclusion criteria were considered, that causes that no strong statistical data about the influence of the age in the arterial localization. It was achieved to solve the confusion when veins present a heat distribution similar to the artery and in the position of this. it contributes to enhance the rate of location of arteries. In general it is possible to say that the use of infrared thermal images is a good technique to find the foot arteries and can be applied in its characterization in a future. The procedure proposed is a non-invasive technique, and in certain fashion does not requires specialized personnel to achieve locate the arteries. It is portable, safe, and relatively economical.

  7. Arterial endothelial function measurement method and apparatus

    Energy Technology Data Exchange (ETDEWEB)

    Maltz, Jonathan S; Budinger, Thomas F

    2014-03-04

    A "relaxoscope" (100) detects the degree of arterial endothelial function. Impairment of arterial endothelial function is an early event in atherosclerosis and correlates with the major risk factors for cardiovascular disease. An artery (115), such as the brachial artery (BA) is measured for diameter before and after several minutes of either vasoconstriction or vasorelaxation. The change in arterial diameter is a measure of flow-mediated vasomodification (FMVM). The relaxoscope induces an artificial pulse (128) at a superficial radial artery (115) via a linear actuator (120). An ultrasonic Doppler stethoscope (130) detects this pulse 10-20 cm proximal to the point of pulse induction (125). The delay between pulse application and detection provides the pulse transit time (PTT). By measuring PTT before (160) and after arterial diameter change (170), FMVM may be measured based on the changes in PTT caused by changes in vessel caliber, smooth muscle tone and wall thickness.

    Basilar artery thrombosis constitutes 1% of all types of stroke, carries a mortality rate of up to 90%, and is one of the rarer causes of sudden death. It leads to brain stem ischemia and commonly presents with impaired consciousness, cranial nerve palsy, hemiplegia or quadriplegia, and sudden collapse. Clinically, the diagnosis of basilar artery thrombosis is made on clinical symptoms, along with a hyperdense basilar artery in antemortem computed tomography (CT) scan. To our knowledge, whether a hyperdense basilar artery indicates basilar artery thrombosis on postmortem CT scan is not documented in the literature. We present a case report of a 55-year-old man who on postmortem CT scan showed a hyperdense basilar artery and was subsequently confirmed to be a fatal basilar artery thrombosis. We suggest that a hyperdense basilar artery on postmortem CT should prompt the pathologist to consider basilar artery thrombosis. PMID:27049662

    Background Some individuals have multiple renal arteries. Severe stenosis in one of the arteries may cause refractory hypertension. The detection of stenosis within one of the multiple renal arteries usually required invasive procedures, such as computed tomographic angiography (CTA) and magnetic resonance angiography (MRA). This study reported the application of color Doppler sonography (CDS) in the detection of severe stenosis in one of the multiple arteries.Methods Patients with multiple renal arteries and one of the arteries with severe stenosis were retrospectively studied. Peak systolic velocities (PSV) of renal arteries and the intrarenal CDS patterns were collected and compared. The diagnosis was confirmed by digital subtraction angiography (DSA).Results Four children with multiple renal arteries and one of the arteries with stenosis were investigated. They were admitted due to refractory hypertension. CDS screening identified two renal arteries in one kidney of each patient with one of the two renal arteries having stenosis >70%. The PSV of the stenosed arteries were much higher, and the intrarenal CDS patterns supplied by the stenosed arteries changed into T-P patterns.Conclusion Non-invasive CDS technology may be a useful method to identify severe stenosis in one of multiple renal arteries in young patients.

    Pawlikowski, M; Pfitzner, R; Wachowiak, J

    1994-01-01

    Mineralogical investigations of calcifications located in coronary vessels were performed on the material obtained from the endarterectomized arteries of 18 patients (15 M, 3 F, aged 36-65) during surgical revascularization procedures consisting in coronary artery bypass grafting. The samples were tested using scanning microscopy, X-ray diffractometry, infrared spectroscopy, atomic absorption spectroscopy, electron microprobe and neutron activation spectroscopy. The results of analyses were calculated with the use of computer programmes. Two types of mineralization were determined: 1. secret mineralization identified as higher than normal content of elements in biological tissues, not demonstrating any mineral grains, and 2. apparent mineralization, appearing micro- and macroscopically as grains composed mainly of hydroxyapatite containing admixture of carbonate groups, i.e. a mineral identical with apatite present in bones, or as calcification of other tissues (heart valves, lungs etc.). The authors suggest that the phenomenon of mineralization should be taken into consideration in the preventive treatment of coronary atheriosclerosis. PMID:7808039

    Increased atherosclerotic plaque formation can lead to lumen reduction and finally to lumen obstruction. Percutaneous transluminal angioplasty (PTA) or balloon angioplasty (dilation) are approaches generally used to treat coronary, but also peripheral atherosclerotic disease. Their goal is to restore the blood supply. The repair process or restructuring of the artery after balloon angioplasty comprises two major features, neointimal formation and geometrical remodeling, and results in a decre...

    Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms. On the other hand, a persistent trigeminal artery variant feeding both the anterior inferior cerebellar artery and the posterior inferior cerebellar artery territory is very rare. We present this uncommon anomalous artery along with digital subtraction angiography findings and discuss its clinical significance in light of the literature. PMID:19821254

    Occurrence of vascular variations in the upper limb is not uncommon and is well described in the medical literature. However, occurrence of superficial ulnar artery associated with unusual origin of the common interosseous and ulnar recurrent arteries is seldom reported in the literature. In the present case, we report the anomalous origin of common trunk of common interosseous, anterior and posterior ulnar recurrent arteries from the radial artery, in a male cadaver. Further, ulnar artery had presented superficial course. Knowledge of anomalous arterial pattern in the cubital fossa reported here is clinically important during the angiographic procedures and plastic surgeries. PMID:27437201

    Objective: To evaluate the method and result of thyroid artery embolization as a new therapy for hyperthyroidism. Methods: Twenty-two patients with hyperthyroidism underwent selective thyroid artery embolization. Totally 52 thyroid arteries were embolized with microspheres. The indications to this therapy were following: hyperthyroid patients having indications to surgical and 131I therapy, clinically being difficult to complete the preparation for subtotal thyroidectomy and having high risk for surgical process because of their huge thyroid gland. Results: Serum level of thyroid hormones dropped significantly [median T3 from 8.8 nmol/L (4.3-43.0 nmol/L) to 4.0 nmol/L (1.1-9.2 nmol/L), median T4 from 206.4 nmol/L (77.4-748.2 nmol/L) to 144.5 nmol/L (25.8-279.9 nmol/L), P 131I treatment of hyperthyroidism.

    Atherosclerosis, the narrowing of vessel diameter and build-up of plaques in coronary arteries, leads to an increase in the shear stresses present, which can be used as a physics-based trigger for targeted drug delivery. In order to develop appropriate nanometer-size containers, one has to know the morphology of the critical stenoses with isotropic micrometer resolution. Micro computed tomography in absorption and phase contrast mode provides the necessary spatial resolution and contrast. The present communication describes the pros and cons of the conventional and synchrotron radiation-based approaches in the visualization of diseased human and murine arteries. Using registered datasets, it also demonstrates that multi-modal imaging, including established histology, is even more powerful. The tomography data were evaluated with respect to cross-section, vessel radius and maximal constriction. The average cross-section of the diseased human artery (2.31 mm2) was almost an order of magnitude larger than the murine one (0.27 mm2), whereas the minimal radius differs only by a factor of two (0.51 mm versus 0.24 mm). The maximal constriction, however, was much larger for the human specimen (85% versus 49%). We could also show that a plastic model used for recent experiments in targeted drug delivery represents a very similar morphology, which is, for example, characterized by a maximal constriction of 82%. The tomography data build a sound basis for flow simulations, which allows for conclusions on shear stress distributions in stenosed blood vessels.

  3. Assessment of conduit artery vasomotion using photoplethysmography

    Vasomotion is a spontaneous oscillation of vascular tone. The phenomenon has been observed in small arterioles and capillaries as well as in the large conduit arteries. The layer of smooth muscle cells that surrounds a blood vessel can spontaneously and periodically change its tension and thereby the arterial wall stiffness also changes. As the understanding of the phenomenon is still rather obscure, researchers would benefit from a low-cost and reliable investigation technique such as photoplethysmography (PPG). PPG is an optical blood pulsation measurement technique that can offer substantial information about the arterial stiffness. The aims of this pilot study were to evaluate the usefulness of the PPG technique in the research of vasomotion and to investigate vasomotion in the relatively large conduit arteries. Continuous 15 minute long measurements of posterior tibial artery wall stiffness were taken. Artery diameter, electrocardiogram, blood pressure and respiration were also simultaneously registered. Fast Fourier Transform power spectra were calculated to identify unique stiffness oscillations that did not correspond to fluctuations in the systemic parameters and thus would indicate vasomotion. We concluded that photoplethysmography is a convenient method for the research of the vasomotion in large arteries. Local stiffness parameter b/a is more accurate to use and easier to measure than the pulse wave velocity which describes stiffness of a segment of an artery. Conduit arteries might exhibit a low amplitude high frequency vasomotion ( 9 to 27 cycles per minute). Low frequency vasomotion is problematic to distinguish from the passive oscillations imposed by the arterial pressure.

    Coronary arteries have been extensively described and recognized by gross anatomic studies. However, in the clinical setting, the recognition of the conal artery is essential during coronary angiography, as well as certain congenital heart conditions such as tetralogy of Fallot. In order to provide a complete anatomic and physiologic correlation of the actual incidence and distribution of the conal artery we examined 300 formalin fixed hearts with gross dissections and 300 coronary angiograms. The conal artery was identified in all hearts examined and five main patterns were recognized. In Type A (193, 32.1%), the conal artery arose as a branch of the right coronary artery (RCA); in Type B (96, 16%), the conal artery arose from the common coronary ostium with the RCA; in Type C (242, 40.3%), the conal artery took origin from the right aortic sinus as an independent artery; in Type D (48, 8%), multiple conal arteries were present and arose from the RCA as separate branches (32, 66.6%), from a common ostium with the RCA (8, 16.6%) or from the aortic sinus (8, 16.6%); in Type E (22, 3.6%), the conal artery arose as a branch of the right ventricular branch (17, 2.8%) or acute marginal artery (5, 0.8%). The relative prevalence of the five patterns as well as the morphology and the topography of the conal artery varied significantly with the degree of coronary luminal stenosis (as observed during angiography) and also with the degree of hypertrophied ventricular wall (as observed during gross dissections).

    Origins and distribution of the human inferior phrenic arteries were studied by dissecting 68 Japanese adult cadavers. The inferior phrenic arteries were usually observed as paired (left and right) vessels. Their origins were summarized as follows: a) the aorta itself (85/138 cases, 61.6%), b) the ventro-visceral arteries (celiaco-mesenteric system of the aorta) including the celiac trunk (39/138 cases, 28.2%) and the left gastric artery (4/138 cases, 2.9%), and c) the latero-visceral arteries (adreno-renal system of the aorta) including the middle adrenal artery (4/138 cases, 2.9%) and the renal artery (6/138 cases, 4.3%). The left and right arteries occasionally originated in common trunk from the aorta, celiaco-mesenteric system or adreno-renal system (22/138 cases, 15.9%). A typological diagram explaining these variations is given. The inferior phrenic arteries, especially the left ones, sometimes issued visceral or esophageal branches. This fact indicates that the inferior phrenic arteries are homologous with the celiac trunk and mesenteric arteries. It is further discussed that the celiac trunk and mesenteric arteries are originally paired vessels, through introduction of our previous typological diagram of the abdominal arteries. PMID:9781269

    Full Text Available La regeneración de plantas in vitro vía embriogénesis somática es un prerrequisito indispensable, para la aplicación de algunas herramientas de la Biotecnología en la mejora genética de las plantas y más aún en el caso de los cítricos. Para aumentar la cantidad de estos cultivos en las plantaciones, se pueden usar técnicas de propagación in vitro, como la embriogénesis somática, que requieren de medios de cultivo artificiales y fitohormonas. Debido a los altos costos de las fitohormonas, una alternativa cubana es el uso de biorreguladores del crecimiento de producción nacional, como el Pectimorf ® y los análogos de brasinoesteroides: Biobras-6 y MH5. Estos biorreguladores, al igual que el 24-Epibrasinólido, son efectivos en los procesos morfogenéticos, generalmente a bajas concentraciones, como sustitutos o complementos de las auxinas y citoquininas. Se empleó la técnica de cultivo de óvulos fecundados in vitro, para obtener una línea celular embriogénica de Citrus reshni Hort. ex Tan y como fuente de óvulos fecundados, se tomaron ovarios de dicha especie procedentes de árboles de la Estación de Cítricos de Ceiba del Agua en Caimito, provincia La Habana. Para el mantenimiento de la línea embriogénica, se utilizaron callos embriogénicos de la línea celular establecida. Este trabajo estuvo dirigido a evaluar el efecto del Pectimorf ® y los brasinoesteroides, MH5, Biobras-6 y 24-Epibrasinólido, en la obtención y el mantenimiento de la línea celular embriogénica de mandarina Cleopatra (Citrus reshni Hort. ex Tan.. En los resultados se pudo comprobar un incremento en la masa fresca del callo embriogénico en un menor tiempo de cultivo mediante el uso de estos biorreguladores.

    Full Text Available Kawasaki disease (KD is an acute vasculitis syndrome of unknown etiology. It occurs in infants and young children,affecting mainly small and medium-sized arteries, particularly the coronary arteries. Generalized microvasculitis occurs in the first 10 days, and the inflammation persists in the walls of medium and small arteries, especially the coronary arteries, and changes to coronary artery aneurysms.We report the case of a 10-month-old girl referred to our center three months after the onset of disease due to the aneurysmsof the coronary arteries. During the acute phase of her illness, she received 2 gr/kg intravenous gamma globulin; and afterher referral to us, the patient was treated by antiaggregant doses of acetylsalicylic acid (ASA (5 mg/kg and Warfarin (1 mg/daily. At three months’ follow-up, the aneurysms still persisted in the echocardiogram.

    Cranial nerve dysfunction, obstruction hydrocephalus, signs of brain stem dysfunction, and signs of a space-occupying lesion in the posterior fossa are presumed to be related to a megadolicho basilar artery, if present. Since there are no large series of patients with such vascular anomaly, a bias in relating symptoms with the presence of a megadolicho basilar artery is not excluded. We therefore studied retrospectively the incidence of megadolicho and dolicho basilar artery on cranial CT-scan of 3332 patients of 50 years and older. Patient records were reviewed for the above mentioned symptoms. 12 out of 22 patients with a megadolicho basilar artery and 2 patients out of 40 with a dolicho basilar artery had one or two of these symptoms. It is concluded that a megadolicho basilar artery can cause cranial nerve dysfunction, obstruction hydrocephalus, signs of brain stem dysfunction, and signs of a space-occupying lesion in the posterior fossa.

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

Fifty seven year- old female patient presented with a sudden onset visual loss in her left eye. Best corrected visual acuity (BCVA levels were 1.0 and 0.7 in the right and left eye, respectiveley. Dilated fundus examination revealed no pathological finding in the right eye. Whereas calcified plaque was seen in upper arquat artery bifurcation in the left eye. Pallorness with retinal edema was seen in this arterial trace. Retinal artery occlusion was diagnosed and patient was referred for hyperbaric oxygen therapy. After a total of 20 sessions of hyperbaric oxygen therapy, the calcified plaques disappeared and her BCVA increased to 20/20. Hyperbaric oxygen treatment is vision-saving method which should be considered in retinal artery occlusion.

    Advances in computational methods and medical imaging techniques have enabled accurate simulations of subject-specific blood flows at the level of individual blood cell and in complex arterial networks. While in the past, we were limited to simulations with one arterial bifurcation, the current state-of-the-art is simulations of arterial networks consisting of hundreds of arteries. In this paper, we review the advances in methods for vascular flow simulations in large arterial trees. We discuss alternative approaches and validity of various assumptions often made to simplify the modeling. To highlight the similarities and discrepancies of data computed with different models, computationally intensive three-dimensional (3D) and inexpensive one-dimensional (1D) flow simulations in very large arterial networks are employed. Finally, we discuss the possibilities, challenges, and limitations of the computational methods for predicting outcomes of therapeutic interventions for individual patients. PMID:20836052

    Periadventitial adipose tissue produces vasoactive substances that influence vascular contraction. Earlier studies addressed this issue in aorta, a vessel that does not contribute to peripheral vascular resistance. We tested the hypothesis that periadventitial adipose tissue modulates contraction of smaller arteries more relevant to blood pressure regulation. We studied mesenteric artery rings surrounded by periadventitial adipose tissue from adult male Sprague-Dawley rats. The contractile response to serotonin, phenylephrine, and endothelin I was markedly reduced in intact vessels compared with vessels without periadventitial fat. The contractile response to U46619 or depolarizing high K+-containing solutions (60 mmol/L) was similar in vessels with and without periadventitial fat. The K+ channel opener cromakalim induced relaxation of vessels precontracted by serotonin but not by U46619 or high K+-containing solutions (60 mmol/L), suggesting that K+ channels are involved. The intracellular membrane potential of smooth muscle cells was more hyperpolarized in intact vessels than in vessels without periadventitial fat. Both the anticontractile effect and membrane hyperpolarization of periadventitial fat were abolished by inhibition of delayed-rectifier K+ (K(v)) channels with 4-aminopyridine (2 mmol/L) or 3,4-diaminopyridine (1 mmol/L). Blocking other K+ channels with glibenclamide (3 micromol/L), apamin (1 micromol/L), iberiotoxin (100 nmol/L), tetraethylammonium ions (1 mmol/L), tetrapentylammonium ions (10 micromol/L), or Ba2+ (3 micromol/L) had no effect. Longitudinal removal of half the perivascular tissue reduced the anticontractile effect of fat by almost 50%, whereas removal of the endothelium had no effect. We suggest that visceral periadventitial adipose tissue controls mesenteric arterial tone by inducing vasorelaxation via K(v) channel activation in vascular smooth muscle cells. PMID:15302842

In order to explain the various expressions of this system, we have proposed a typological model, in which celiacomesenteric arteries develop as paired or bilaterally symmetrical primordial vessels originated from the anterior aspect of the aorta, and these vessels anastomose each other with longitudinal and horizontal pathways. Here, we report 3 unusual cases characterized by arterial rings, formed by the left gastric, left accessory hepatic, proper hepatic, anterior pancreaticoduodenal, and dorsal pancreatic arteries. The dorsal pancreatic and anterior pancreaticoduodenal arteries are located to the right and left of the embryonic pancreas developing in the dorsal mesentery, respectively. Such hepatopancreatic arterial rings simultaneously containing right and left elements can only be explained using our typological model, in which the concept of paired arteries or bilateral symmetry is introduced.

    Subarachnoid hemorrhage (SAH) is a serious condition, occurring more frequently in females than in males. SAH is mainly caused by rupture of an intracranial aneurysm, which is formed by localized dilation of the intracranial arterial vessel wall, usually at the apex of the arterial bifurcation. T...... female preponderance is usually explained by systemic factors (hormonal influences and intrinsic wall weakness); however, the uneven sex distribution of intracranial aneurysms suggests a possible physiologic factor-a local sex difference in the intracranial arteries....

  13. Continuous blood gas monitoring in femoral arteries

    Science.gov (United States)

    Schlain, Les A.; Spar, Steven M.; Dellinger, Bart

    1995-05-01

    Continuous intra-arterial blood gas monitoring is a potentially valuable tool in the surgical and intensive care arenas. Patient oxygenation and acid base status can change rapidly and without warning. The ability to monitor pHa, PaCO2 and PaO2 in arterial blood will be a major medical advance for the anesthesiologist and intensivist. Intra-arterial blood gas sensors are typically placed in radial arteries. In certain patient populations accurate monitoring is not possible in radial arteries due to arterial environmental factors such as hypotension, vasoconstriction and atherosclerotic disease. These same factors can make radial cannulation difficult resulting in traumatic catheter insertion, thereby further compromising flow conditions. In situations where radial artery flow is expected to be compromised, selecting a large vessel for sensor placement is desirable. We report an initial feasibility study of our blood gas monitoring system using the femoral artery as the sensing site. Clinical results are presented as well as potential advantages and disadvantages associated with monitoring in the femoral artery.

    The aim of this study was to analyze the arterial supply of the sesamoid bones of the hallux. Twenty-two feet from adult cadavers were injected with epoxide resin or an acrylic polymer in methyl methacrylate (Acrifix) and subsequently processed by two slice plastination methods and the enzyme maceration technique. Afterwards, the arterial supply of the sesamoid bones was studied. The first plantar metatarsal artery provided a medial branch to the medial sesamoid bone. The main branch of the first plantar metatarsal artery continued its course distally along the lateral side of the lateral sesamoid and supplied it. The supplying arteries penetrated the sesamoid bones on the proximal, plantar, and distal sides. The analysis and cataloging of the microvascular anatomy of the sesamoids revealed the first plantar metatarsal artery as the main arterial source to the medial and lateral sesamoid bones. In addition, the first plantar metatarsal artery ran along the lateral plantar side of the lateral sesamoid bone, suggesting that this artery is at increased risk during soft-tissue procedures such as hallux valgus surgery.

Data were computerized using the SINPE© system for integrated electronic protocols and tested in a pilot study.Results:The data entered onto the system was first used to create a Master protocol, organized into a structure of top-level directories covering a large proportion of the content on vascular diseases as follows: patient history; physical examination; supplementary tests and examinations; diagnosis; treatment; and clinical course. By selecting items from the Master protocol, Specific protocols were then created for the 22 arterial sites most often involved by aneurysms. The program provides a method for collection of data on patients including clinical characteristics (patient history and physical examination, supplementary tests and examinations, treatments received and follow-up care after treatment. Any information of interest on these patients that is contained in the protocol can then be used to query the database and select data for studies.Conclusions:It proved possible to construct a database of clinical and surgical data on the arterial aneurysms of greatest interest and, by adapting the data to specific software, the database was integrated into the SINPE© system, thereby providing a standardized method for collection of data on these patients and tools for retrieving this information in an organized manner for use in scientific studies.

    Coronary artery disease is a leading cause of morbidity and mortality across the world. Percutaneous coronary intervention has become the major technique of revascularization. However, restenosis remains a major limitation of this procedure. Recently the need for repeat intervention due to restenosis, the most vexing long-term failure of percutaneous coronary intervention, has been significantly reduced owing to the introduction to two major advances, intracoronary brachytherapy and the drug-eluting stents, intracoronary brachytherapy has been employed in recent years to prevent restenosis lesions with effective results, principally in in-stent restenosis. Restenosis is generally considered as an excessive form of normal wound healing divided up in processes: elastic recoil, neointimal hyperplasia, and negative vascular remodeling. Restenosis has previously been regarded as a proliferative process in which neointimal thickening, mediated by a cascade of inflammatory mediators and other factors, is the key factor. Ionizing radiation has been shown to decrease the proliferative response to injury in animal models of restenosis. Subsequently, several randomized, double-blind trials have demonstrated that intracoronary brachytherapy can reduce the rates to both angiographic restenosis and clinical event rates in patients undergoing percutaneous coronary intervention for in-stent restenosis. Some problems, such as late thrombosis and edge restenosis, have been identified as limiting factors of this technique. Brachytherapy is a promising method of preventing and treating coronary artery restenosis.

    Pulmonary arterial hypertension (PAH) is a rare disorder characterized by progressive obliteration of the pulmonary microvasculature, resulting in elevated pulmonary vascular resistance and premature death. According to the current classification, PAH can be associated with exposure to certain drugs or toxins, particularly appetite suppressant drugs, such as aminorex, fenfluramine derivatives and benfluorex. These drugs have been confirmed to be risk factors for PAH and were withdrawn from the market. The supposed mechanism is an increase in serotonin levels, which was demonstrated to act as a growth factor for the pulmonary arterial smooth muscle cells. Amphetamines, phentermine and mazindol were less frequently used but are also considered as possible risk factors for PAH. Dasatinib, a dual Src/Abl kinase inhibitor, used in the treatment of chronic myelogenous leukaemia was associated with cases of severe PAH, in part reversible after its withdrawal. Recently several studies raised the potential endothelial dysfunction that could be induced by interferon, and few cases of PAH have been reported with interferon therapy. Other possible risk factors for PAH include: nasal decongestants, like phenylpropanolamine, dietary supplement - L-Tryptophan, selective serotonin reuptake inhibitors, pergolide and other drugs that could act on 5HT2B receptors. Interestingly, PAH remains a rare complication of these drugs, suggesting possible individual susceptibility and further studies are needed to identify patients at risk of drugs induced PAH.

    Full Text Available Goldenhar Syndrome is characterized by craniofacial, ocular and vertebral defects secondary to abnormal development of the 1st and 2nd branchial arches and vertebrae. Other findings include cardiac and vascular abnormalities. Though these associations are known, the specific anomalies are not well defined. We present a 7-month-old infant with intermittent respiratory distress that did not improve with respiratory interventions. Echocardiogram suggested a double aortic arch. Cardiac CT angiogram confirmed a right arch and aberrant, stenotic left subclavian artery, dilation of the main pulmonary artery, and agenesis of the left thyroid lobe. Repeat echocardiograms were concerning for severely dilated coronary arteries. Given dilation, a rheumatologic workup ensued, only identifying few weakly positive autoantibodies. Further imaging demonstrated narrowing of the aorta below the renal arteries and extending into the common iliac arteries and proximal femoral arteries. Given a physical exam devoid of rheumatologic findings, only weakly positive autoantibodies, normal inflammatory markers, and presence of the coronary artery dilation, the peripheral artery narrowings were not thought to be vasculitic. This case illustrates the need to identify definitive anomalies related to Goldenhar Syndrome. Although this infant’s presentation is rare, recognition of specific vascular findings will help differentiate Goldenhar Syndrome from other disease processes.

    To evaluate the feasibility and usefulness of the transradial approach for intra-arterial chemoembolization therapy in patients with hepatocellular carcinomas. Twenty-nine patients with hepatocellular carcinoma who underwent intra-arterial chemoembolization via the radial artery approach were involved in this study. All underwent Allen's test to check ulnar arterial patency. In all cases, we used the radial approach hepatic artery (RHA) catheter designed by ourselves, evaluating the selection ability of the hepatic artery using an RHA cathter, the number of punctures, the procedure time, and compression time at the puncture site as well as complications occurring during and after the procedure. Except for three in which puncture failure, brachial artery variation or hepatic artery variation occurred, all procedures were successful. The mean number of punctures was 3.5 and the average duration of the whole procedure was one and half hours. This gradually decreased as the number of procedures increased. The average duration at a compression of puncture site was 12 minutes. There were no major complications. Minor complications included minimal intimal dissection of the radial artery (3.8%), reversible vasospasm of the radial artery (7.7%), hematoma at a puncture site (7.7%) and transient neurologic deficit (3.8%). The transradial approach using an RHA catheter for intra-arterial chemoembolization theraphy in patients with hepatocellular carcinomas was technically feasible, with acceptable levels of safety. It may be a good alternative to absolute bed rest with a sand bag after the femoral approach.

    Full Text Available Abstract Introduction Conversion of multiple hepatic arteries into a single vascular supply is a very important technique for repeat hepatic arterial infusion chemotherapy using an implanted port catheter system. Catheterization of a replaced left hepatic artery arising from a left gastric artery using a percutaneous catheter technique is sometimes difficult, despite the recent development of advanced interventional techniques. Case presentation We present a case of a 70-year-old Japanese man with multiple hepatocellular carcinomas in whom the replaced left hepatic artery arising from the left gastric artery needed to be embolized. After several failed procedures, the replaced left hepatic artery was successfully catheterized and embolized with a microcatheter and microcoils via the right gastric artery through the anastomosis. Conclusion A replaced left hepatic artery arising from a left gastric artery can be catheterized via a right gastric artery by using the appropriate microcatheter and microguidewires, and multiple hepatic arteries can be converted into a single supply.

    The trigeminal artery is one of four primitive anastomoses between the internal carotid artery and vertebrobasilar system that regresses in the sixth week of fetal development. A persistent trigeminal artery (PTA) is generally an incidental finding but may also be associated with intracranial vascular pathologies such as aneurysms, arteriovenous malformations, and cranial nerve compression syndromes. We present an extremely rare case of a right PTA with an associated bleeding fusiform aneurysm located in the carotidian (lateral) part of the PTA. In addition, this rare anatomic variation was associated with bilateral absence of the posterior communicating arteries, a left posterior cerebral artery originating from the left internal carotid artery, and agenesis of the A1 segment of the left anterior cerebral artery.

    The trigeminal artery is an anastomosis between the embryonic precursors of the vertebrobasilar and carotid systems, and may persist into adult life. The association of the persistent primitive trigeminal artery (PTA) with cerebral aneurysm is well documented in the literature and, in general, aneurysms are located in the anterior circulation. We describe a patient who presented with a panencephalic Fisher III subarachnoid hemorrhage due to rupture of an intracranial aneurysm. Digital arteriography showed a saccular aneurysm in the middle third of the basilar artery, adjacent to the junction with a persistent trigeminal artery. She was submitted to endovascular treatment with embolization of the basilar artery aneurysm with coils. Aneurysms at the PTA junction with the basilar artery are rare. This paper describes a case of PTA associated with an aneurysm in the basilar artery at PTA junction and briefly reviews the literature. PMID:22005697

    Balloon angioplasty and stent placement in close proximity to the bifurcation of the branch pulmonary arteries can be challenging. Multiple approaches have been previously described, though none of these approaches both treats bilateral proximal branch pulmonary artery stenosis and provides an anchor for a transcatheter pulmonary valve replacement. We report a novel approach that involves serial stent placement and balloon dilation through the struts of the stent in each pulmonary artery, along with balloon expansion of the proximal portion of the stents to the diameter of the main pulmonary artery. In the two cases we describe, this strategy resulted in significant relief of branch pulmonary artery obstruction without compromising the anatomy of the main pulmonary artery segment. This technique can be an effective way to alleviate stenoses of the bilateral proximal branch pulmonary arteries and provides a landing zone for a future transcatheter pulmonary valve. PMID:26256829

    Full Text Available This paper aimed to define the origin and distribution of the celiac artery and its collateral branches in 15 fowls from the Columba livia species, which were obtained from the Zoonosis Control Center of Brasilia, Brazil. In order to mark the arterial system of the specimens, the left brachiocephalic trunk was canullated and a colored water-latex solution was injected there. Afterwards, fowls were fixed in a 10% v/v formaldehyde solution and dissected with appropriate equipment, presenting the results described in this paper. The celiac artery originated from the ventral face of the descendent aorta. The first collateral branch arose from the celiac artery itself, forming the esophageal artery. Then, the celiac artery has bifurcated into two branches, named left and right branches of the celiac artery. The left branch emitted the proventricular ventral artery, followed by the splenic arteries, proventricular dorsal artery, and the left hepatic artery. The left branch has bifurcated into two branches, known as ventral and left gastric arteries. The right branch emitted the right hepatic artery, followed by the ileal artery and the right gastric artery. Finally, the right branch turned into the pancreaticoduodenal artery. Our findings showed a great similarity with the avian lineages of the Gallus gallus species, except for the lack of ileocecal artery, cystic branches, and dorsal gastric artery.

    Popliteal artery entrampment is a rare condition, occurring in young subjects, that causes ischemia of the extremity. The anatomical background is the compression or occlussion of the popliteal artery caused by forced plantar or dorsal flexion. We report a 32 year-old sportsman who presented with gangrene of the right first toe and a history of three months of progressive claudication. The Ankle-Brachial index and pulse volume curve registries showed a severe ischemia below the knee. Angiography showed a medial deviation of the popliteal artery associated to stenosis and aneurysm formation. A CT scan of the contralateral artery was normal. The patient was operated using a posterior approach, performing a reverse saphenous vein bypass graft and excising the popliteal artery. The postoperative period was uneventful. PMID:16554929

  16. Value of scintiangiography in arterial disease

    International Nuclear Information System (INIS)

    Arterial visualization using the gamma camera was achieved by peripheral intravenous injection of technetium pertechnetate Tc 99m 253 times in 200 patients. This technique, which successfully images the arterial tree to the level of the wrist and ankle, was validated by blind comparison of the scintiangiograms with contrast arteriograms or surgical findings or both in 93 studies. Although scintiangiography has less resolution than contrast arteriography, it provides quantitative and other important supplementary information in the diagnosis and management of patients with arterial disease. Scintiangiography has accurately diagnosed arterial occlusions (atherosclerotic, traumatic, and embolic), true and false aneurysms, and arterial stenoses. Patients sustaining trauma to the extremities may be evaluated by scintiangiography as a screening technique. Postoperatively, scintiangiography has replaced contrast arteriography for assessing patency of grafts and completeness of thromboembolectomy and for the long-term follow-up of these patients

  17. Pulse Wave Propagation in the Arterial Tree

    The beating heart creates blood pressure and flow pulsations that propagate as waves through the arterial tree that are reflected at transitions in arterial geometry and elasticity. Waves carry information about the matter in which they propagate. Therefore, modeling of arterial wave propagation extends our knowledge about the functioning of the cardiovascular system and provides a means to diagnose disorders and predict the outcome of medical interventions. In this review we focus on the physical and mathematical modeling of pulse wave propagation, based on general fluid dynamical principles. In addition we present potential applications in cardiovascular research and clinical practice. Models of short- and long-term adaptation of the arterial system and methods that deal with uncertainties in personalized model parameters and boundary conditions are briefly discussed, as they are believed to be major topics for further study and will boost the significance of arterial pulse wave modeling even more.

  18. Arterial Complications of Percutaneous Transhepatic Biliary Drainage

    International Nuclear Information System (INIS)

    Purpose: To report on the frequency and treatment of arterial complications due to percutaneous transhepatic biliary drainage (PTBD).Materials: Lesions of the intrahepatic artery were encountered in 10 of 525 patients treated by PTBD (2%). Hemobilia followed in 9 patients and subcapsular hematoma in 1. Seven patients had a benign biliary stenosis and 3 had a malignant stenosis.Results: The bleeding resolved spontaneously in 3 patients. In 7 it required arterial embolization, which was successfully achieved either through the percutaneous catheter (n= 3) or by arteriography (n= 4).Conclusion: Arterial bleeding is a relatively rare complication of PTBD that can easily be treated by selective arterial embolization when it does not resolve spontaneously. In this series its frequency was much higher (16%) when the stenosis was benign than when it was malignant (0.6%)

    2014-03-01

    Pulsatile tinnitus can result from various vascular etiologies that cause transmission of pulsatile turbulent flow into the inner ear. Less commonly, non-vascular sources cause increased blood flow and transmission of sound perceived as tinnitus. Thorough clinical examination leads to appropriate imaging evaluation and therapeutic planning. Most pulsatile tinnitus results from expected mechanisms, such as dural arteriovenous fistula, jugular bulb dehiscence, or paraganglioma; however, the literature contains reports of numerous rare causes, particularly variant anatomic morphologies. We present the case of a novel cause of pulsatile tinnitus in which collateral vascular flow compensated for decreased normal intracranial cerebral arterial supply and might have caused catastrophic consequences if intervened upon after assumptions based on an incomplete evaluation.

    Aim. To analyze Inferior Mesenteric Artery in fetuses through its site of origin, length, diameter, and variation of its branches. Method. 100 fetuses were collected from various hospitals in Warangal at Kakatiya Medical College in Andhra Pradesh, India, and were divided into two groups, group I (second-trimester fetuses) and group II (third-trimester fetuses), followed by dissection. Result. (1) Site of Origin. In group I fetuses, origin of Inferior Mesenteric Artery was at third lumbar vertebra in 33 out of 34 fetuses (97.2%). In one fetus it was at first lumbar vertebra, 2.8%. In all group II fetuses, origin of Inferior Mesenteric Artery was at third lumbar vertebra. (2) Length. In group I fetuses it ranged between 18 and 30 mm, average being 24 mm except in one fetus where it was 48 mm. In group II fetuses the length ranged from 30 to 34 mm, average being 32 mm. (3) Diameter. In group I fetuses it ranged from 0.5 to 1 mm, and in group II fetuses it ranged from 1 to 2 mm, average being 1.5 mm. (4) Branches. Out of 34 fetuses of group I, 4 fetuses showed variation. In one fetus left colic artery was arising from abdominal aorta, 2.9%. In 3 fetuses, Inferior Mesenteric Artery was giving a branch to left kidney, 8.8%. Out of 66 fetuses in group II, 64 had normal branching. In one fetus left renal artery was arising from Inferior Mesenteric Artery, 1.5%, and in another fetus one accessory renal artery was arising from Inferior Mesenteric Artery and entering the lower pole of left kidney. Conclusion. Formation, course, and branching pattern of an artery depend on development and origin of organs to attain the actual adult position. PMID:27313956

    A three-dimensional multilayer model of mechanical response for analyzing the effect of pressure on arterial failure is presented in this work. The multilayer arterial wall is considered to be composed of five different layers. The three-dimensional effects are incorporated within the five-concentric axisymmetric layers while incorporating the nonlinear elastic characteristics under combined extension and inflation. Constitutive equations for fiber-reinforced material are employed for three of the major layers, i.e., intima, media and adventitia and an isotropic material model is employed for the other two layers, i.e., endothelium and internal elastic lamina. Our own developed three-dimensional five-layer model has been utilized to model propagated rupture area of the arterial wall. Required parameters for each layer are obtained by using a nonlinear least square method fitted to in vivo non-invasive experimental data of human artery and the effects of pressure on arterial failure are examined. The solutions from our computational model are compared with previous studies and good agreements are observed. Local stresses and strain distributions across the deformed arterial wall are illustrated and consequently the rupture area is predicted by varying luminal pressure in the physiological range and beyond. The effects of pressure on the arterial failure have been interpreted based on this comprehensive three-dimensional five-layer arterial wall model. This is the first study which employs two constitutive equations and incorporates a five-layer arterial wall model in three-dimensions based on in vivo non-invasive experimental data for a human artery.

El término “adventicia” proviene del latín adventicius, que significa “venido de afuera, extraño”. Estos conceptos tal vez constituyan la causa de la subestimación del papel fisiológico de esta túnica. Al presente es bien conocido que la adventicia contiene vasa vasorum y nervi vasorum con funciones nutricionales y de control, respectivamente. A ello se suma la presencia de factores bioquímicos que serían responsables de cambios en la conducta elástica y viscosa de la pared arterial a través de una regulación de la función muscular lisa.En este trabajo se realiza una síntesis del papel estructural y fisiológico de la adventicia; se analizan además datos clínicos y experimentales que se comparan con resultados originales publicados por el autor.

    Full Text Available Context: Many different patterns have been described to classify the origins of circumflex femoral arteries by many authors since from 1860.The aim of the present study was to classify the circumflex femoral arteries in 100 lower limbs of adult cadavers of both sexes following the recent classification and to compare with the previous studies. Materials and Methods: A total of 100 lower limbs of 50 embalmed human adult cadavers (Male: 37, Female: 13 were dissected and observed for the origins of circumflex femoral arteries in femoral triangle in routine educational dissection in the period of 2005-2009 Results: The medial and lateral circumflex femoral arteries have been classified into three different patterns based on the levels of their origin. Pattern I: Both arteries arose from the profunda femoris artery (56%. Type Ia, medial circumflex femoral artery origin was proximal to the lateral circumflex femoral artery origin (69%; Type Ib, lateral circumflex femoral artery origin was proximal to medial circumflex femoral artery origin (16 %; Type Ic, both arteries arose from a common trunk or at same level (14%. Pattern II: One of the arteries arose from the femoral artery and the other from the profunda femoris artery (36%. Type IIa, the medial circumflex femoral artery arose from the femoral artery (75% and Type IIb, the lateral circumflex femoral artery arose from the femoral artery (25%.Pattern III: Both arteries arose from the femoral artery (7%. The medial circumflex femoral artery was absent in a female cadaver on right side. Conclusion: In every pattern or type, there was significantly unilateral higher occurrence than bilateral occurrence. A precise knowledge of the circumflex femoral arteries in relation to the profunda femoris artery is important in surgical interventions of the hip region

    International Nuclear Information System (INIS)

    Objective: To quantify muscular micro-perfusion and arterial perfusion reserve in peripheral arterial disease (PAD) with dynamic contrast-enhanced ultrasound (CEUS) and transient arterial occlusion. Materials and methods: This study had local institutional review board approval and written informed consent was obtained from all subjects. We examined the dominant lower leg of 40 PAD Fontaine stage IIb patients (mean age, 65 years) and 40 healthy volunteers (mean age, 54 years) with CEUS (7 MHz; MI, 0.28) during continuous intravenous infusion of 4.8 mL microbubbles. Transient arterial occlusion at mid-thigh level simulated physical exercise. With time–CEUS–intensity curves obtained from regions of interest within calf muscles, we derived the maximum CEUS signal after occlusion (max) and its time (tmax), slope to maximum (m), vascular response after occlusion (AUCpost), and analysed accuracy, receiver operating characteristic (ROC) curves, and correlations with ankle-brachial index (ABI) and walking distance. Results: All parameters differed in PAD and volunteers (p max was delayed (31.2 ± 13.6 vs. 16.7 ± 8.5 s, p post as optimal parameter combination for diagnosing PAD and therefore impaired arterial perfusion reserve. Conclusions: Dynamic CEUS with transient arterial occlusion quantifies muscular micro-perfusion and arterial perfusion reserve. The technique is accurate to diagnose PAD.

    2016-06-01

    Pulmonary arterial hypertension (PAH) is characterized by molecular and pathologic alteration to the pulmonary circulation, resulting in increased pulmonary vascular resistance, right ventricular failure, and eventual death. Pharmacologic treatment of PAH consists of use of a multitude of pulmonary vasodilators, sometimes in combination. PAH has been associated with increased thrombosis and disrupted coagulation and fibrinolysis, making anticoagulation an attractive and frequently employed therapeutic modality. Observational studies have provided some insight into the therapeutic potential of anticoagulation in idiopathic PAH, but there is a distinct lack of well-controlled prospective trials. Due to the conflicting evidence, there is a large amount of heterogeneity in the application of therapeutic anticoagulation in PAH and further well-controlled prospective trials are needed to clarify its role in treating PAH.

    Full Text Available We report a case of branch retinal artery occlusion (BRAO in a healthy young girl. An eight-year-old girl presented with sudden loss of vision in her left eye. She had a pale retina with macular edema consistent with extensive BRAO. A thorough workup was performed to determine any etiologic factor. All test results were within normal limits. Her visual acuity improved from finger counting to 20/40 over two weeks, on immediate treatment with intravenous steroids (methyl prednisolone. This case suggests that BRAO can occur in healthy children without any detectable systemic or ocular disorders and a dramatic improvement may be achieved with prompt treatment with intravenous steroids.

    Arterial hypertension is the most common chronic disease in developed countries and it is the leading risk factor for stroke, ischemic heart disease, congestive heart failure, chronic renal failure and peripheral artery disease. Its prevalence appears to be about 30-45% of the general population. Recent European guidelines estimate that up to 15-20% of the hypertensive patients are not controlled on a dual antihypertensive combination and they require three or more different antihypertensive drug classes to achieve adequate blood pressure control. The guidelines confirmed that diuretics, beta-blockers, calcium-channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are suitable for the initiation and maintenance of antihypertensive treatment, either as monotherapy or in combination therapy. Very few antihypertensive agents have reached the market over the last few years, but no new therapeutic class has really emerged. The long-term adherence to cardiovascular drugs is still low in both primary and secondary prevention of cardiovascular diseases. In particular, the issue of compliance is persistently high in hypertension, despite the fixed-dose combination therapy. As a consequence, a cohort of high-risk hypertensive population, represented by patients affected by refractory and resistant hypertension, can be identified. Therefore, the need of controlling BP in high-risk patients may be addressed, in part, by the development of new drugs, devices and procedures that are designed to treat hypertension and comorbidities. In this review we will comprehensively discuss the current literature on recent therapeutic advances in hypertension, including both medical therapy and interventional procedures. PMID:26730462

    Full Text Available En esta revisión, se muestra que la existencia de secuencias del cromosoma Y en las mujeres con síndrome de Turner es un factor de riesgo para el desarrollo de gonadoblastoma, sobre todo si está presente en el cariotipo de las pacientes en forma de mosaico y/o como secuencias del Y ocultas. En la literatura, se han encontrado en los estudios epidemiológicos de cáncer, resultados controversiales en los casos que presentan gonadoblastoma u otros tumores malignos de ovario, en el síndrome de Turner. Algunas mujeres tienen Y pero no desarrollan tumores gonadales. En una población argentina de 282 mujeres con síndrome de Turner se evaluó la presencia de material del cromosoma Y en mosaico por PCR y en 8 de estos pacientes (2,83 % con secuencias del Y, se halló gonadoblastoma luego de extirpar la gónada. En la literatura, la frecuencia de material "escondido" de cromosoma Y (en mosaico es alta en el síndrome de Turner, pero la aparición de gonadoblastoma entre los pacientes con estas secuencias parece ser baja. Las secuencias del gen SRY solo pueden estudiarse como un marcador de mosaicismo, en pacientes con síndrome de Turner, porque el locus para gonadoblastoma/disgerminoma, probablemente se encuentra cerca del centrómero del Y lejos de SRY. Publicaciones recientes, sugieren que la evaluación del riesgo real de desarrollo de tumores gonadales en pacientes con ST con secuencias derivadas del Y, en su constitución cromosómica puede requerir un estudio histopatológico específico, tal como la inmunohistoquímica con OCT4. Por lo tanto, es evidente que la exéresis de las gónadas sigue siendo una herramienta importante para la prevención en pacientes con síndrome de Turner, con sospecha de cromosoma Y ¨escondido¨ o en mosaico, hasta que sea posible aislar los genes implicados en el gonadoblastoma. La autora declara no poseer conflictos de interés.In this review, we show that the existence of Y chromosome sequences in women with

Methods:A Total of 40 cases of patients with subacute thyroiditis and 40 cases of healthy volunteers were selected for study and enrolled in pathology group and control group respectively, color Doppler ultrasonography was conducted to detect peak blood flow velocities (Vmax) of superior thyroid artery and inferior thyroid artery as well as resistance index (RI), and serum was collected to detect thyroid hormone contents, infection indexes and oxidative stress indexes. Results:Peak blood flow velocities Vmax of superior thyroid artery and inferior thyroid artery of pathology group were significantly higher than those of control group, and resistance index RI was not different from that of control group;FT3, FT4, TT3, TT4, ESR, CRP, PCT and MDA of pathology group were significantly higher than those of control group, and SOD and TAOC were significantly lower than those of control group;Vmax of superior thyroid artery and inferior thyroid artery were positively correlated with FT3, FT4, TT3, TT4, ESR, CRP, PCT and MDA, and negatively correlated with SOD and TAOC. Conclusion:Peak blood flow velocities (Vmax) of superior thyroid artery and inferior thyroid artery in subacute thyroiditis are significantly accelerated, Vmax has good consistency with thyroid hormone contents, infection indexes and oxidative stress indexes, and it can accurately assess the severity of the disease.

  15. Selective catheterization of the brachiocephalic arteries via the right brachial artery

    International Nuclear Information System (INIS)

    Selective intra-arterial digital subtraction angiography of the brachiocephalic arteries using the right brachial artery approach was successfully performed for 169 of 173 patients, 33 of whom were outpatients. Catheterization was unsuccessful for four patients; two of them elderly hypertensive men with tortuos brachial arteries, and two of them middle-aged obese women for whom arterial puncture could not be performed. 4-F modified Simmons type catheters were used in this study. Selective catheterizations of both common carotid arteries were successfully performed in all but one patient, a woman whose aberrant right subclavian artery prevented bilateral common carotid arterial catheterizations. Selective catheterizations of the right vertebral and left subclavian arteries, though relatively difficult, were successfully performed in 84.2% and 93.9% of patients, respectively. The mean examination time for a four-vessel study was 24.3 min. No major complications were encountered. Thus, transbrachial selective catheterization of the brachiocephalic arteries proved to be safe, useful, and relatively easy to perform. (orig.)

    Angiography is essential for the detection of bleeding vessels in traumatic vascular injury. Immediately after the diagnosis, transcatheter embolization can be performed for the control of bleeding effectively and easily with proper use of embolic materials. Transcatheter embolization is believed to be the treatment of choice when emergency control is needed, where surgical approach is difficult and in those who are poor candidate for surgery. We have tried bleeding control in 18 cases of trauma over recent 4 years. The results were as follows; 1. Causes of bleeding(cases): Blunt or penetrating trauma (10), latrogenic trauma (8), (Postoperative (5), Needle biopsy (2), Percutaneous hepatic procedure (1)) 2. Embolized vessels: Renal artery branches (8), Hepatic artery branches (2), Arteries supplying chest wall (2), External carotid artery branches (3), Internal carotid artery (1), Circumflex humeral artery (1), Internal iliac artery branches (1). 3. Embolic agents: Gelfoam cubes (16), Stainless steel coils (3), Detachable latex balloon (1). 4. Successful bleeding control was achieved in 17 cases and reduction of the amount of bleeding in one case without significant complications.

  19. Arterial Stiffness and Dialysis Calcium Concentration

    Directory of Open Access Journals (Sweden)

    Fabrice Mac-Way

    2011-01-01

    Full Text Available Arterial stiffness is the major determinant of isolated systolic hypertension and increased pulse pressure. Aortic stiffness is also associated with increased cardiovascular morbidity and mortality in patients with chronic kidney disease, hypertension, and general population. Hemodynamically, arterial stiffness results in earlier aortic pulse wave reflection leading to increased cardiac workload and decreased myocardial perfusion. Although the clinical consequence of aortic stiffness has been clearly established, its pathophysiology in various clinical conditions still remains poorly understood. The aim of the present paper is to review the studies that have looked at the impact of dialysis calcium concentration on arterial stiffness. Overall, the results of small short-term studies suggest that higher dialysis calcium is associated with a transient but significant increase in arterial stiffness. This calcium dependant increase in arterial stiffness is potentially explained by increased vascular smooth muscle tone of the conduit arteries and is not solely explained by changes in mean blood pressure. However, the optimal DCa remains to be determined, and long term studies are required to evaluate its impact on the progression of arterial stiffness.

    Full Text Available ABSTRACT: The renal vasculature was always a subject of varia tions both in the number and pattern of portal of entry into kidney and Perihilar placement of the artery, vein and pelvis. Good anatomical insight is an essential prerequisite besides the surgical expertise. The cadaveric dissection at Shadan Institute of Medical Sciences, Teaching Hospital and Research Centre, revealed superior / upper polar artery arising from the lateral aspect of the aorta just proximal to the origin of Main Renal Artery (MRA. T he main renal artery and the accessory renal artery had almost a common point of origin. Th e peri-hilar segmentation of the main renal artery was a fork like pattern. One of the segmental arteries was long and had its portal of entry into the kidney by perforating the capsule of the ant erior substance of the kidney. The remaining segmental branches had their portal of ent ry through the hilum. The lower two segmental branches were placed anterior to the main renal vein causing altered hilar anatomy. A thorough knowledge of the frequently to the rarel y occurring wide range of variations of renal vasculature has significance in exploration and trea tment of renal trauma, renal transplantation, renal artery embolization, surgery for abdominal ao rtic aneurysm and conservative or radical renal surgery. Such a rare variation including the combination of extra renal peri-hilar segmentation of MRA with superior polar artery is wor thy of concern to the urologists harvesting kidneys from the live donors for performi ng transplantation procedures, partial nephrectomies for the hilar tumors and for Radiologi sts during interpretation of the angiograms

  1. Diagnosis and outcome of cervical artery dissection

    2011-01-01

    Full Text Available Introduction. Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. Diagnosis. Precise diagnosis of dissection of the cervical artery - carotid or vertebral - is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. Treatment. The recommended treatment in the acute phase of cervical artery dissection is anticoagulant or antithrombotic therapy, aimed at preventing a primary or recurrent ischemic event. There have been as yet no results of randomized controlled studies comparing efficacy of both treatments. An ongoing randomized multicentre study is expected to provide answers about the effects of these treatments in cervical artery dissection. Outcome. Complete resolution of arterial abnormalities is achieved in around 46% of stenoses, 33% of occlusions, and 12% of dissecting aneurysms. Recurrent events. Recurrence of cerebral ischemia and cervical artery dissection seems to be rare, although some data suggest that early ischemic and late cervical artery dissection recurrences could be underestimated. Mortality and functional outcome. In comparison with other causes of stroke in young adults, the functional outcome of cervical artery dissection is good in contrast to its socio-professional effects, which may be unsatisfactory. The mortality rate of cervical artery dissection is low, although it may be underestimated since some patients with malignant infarction die before the diagnosis is established. Conclusion. Further research is warranted to improve our understanding of the underlying pathophysiology, to assess the long-term outcome, and ultimately to provide treatment and prevention strategies.

    Full Text Available Background. Hemobilia is a rare, jeopardizing complication of laparoscopic cholecystectomy coming upon usually within 4 weeks after surgery. The first-line management is angiographic coil embolization of hepatic arteries, which is successful in the majority of bleedings: in a minority of cases, a second embolization or even laparotomy is needed. Case Presentation. We describe the case history of a patient in which laparoscopic cholecystectomy was complicated 3 weeks later by massive hemobilia. The cause of haemorrhage was a pseudoaneurysm of a right hepatic artery branching off the superior mesenteric artery; this complication was successfully managed by one-stage angiographic embolization with full recovery of the patient.

    In this paper, a method was proposed that the wall shear stress of artery could be determined by measuring the centerline axial velocity and radial motion of arterial wall simultaneously.The method is simple in application and can get higher precision when it is used to determine the shear stress of arterial wall in vivo.As an example, the shear stress distribution in periodic oscillatory flow of human carotid was calculated and discussed.The computed results show that the shear stress distribution at any given instant is almost uniform and will be zero at the centerline and tends to maximum at the vessel wall.

    High-resolution unsteady three-dimensional flow simulations in large intracranial arterial networks of a healthy subject and a patient with hydrocephalus have been performed. The large size of the computational domains requires the use of thousands of computer processors and solution of the flow equations with approximately one billion degrees of freedom. We have developed and implemented a two-level domain decomposition method, and a new type of outflow boundary condition to control flow rates at tens of terminal vessels of the arterial network. In this paper, we demonstrate the flow patterns in the normal and abnormal intracranial arterial networks using patient-specific data. PMID:19414460

    2011-01-01

    Background At present, revascularization is still one of the most critical technologies in orthotopic liver transplantation (OLT). Hepatic artery (HA) variations occur frequently in both donors and recipients. Moreover, there are always some pathological changes in the recipient hepatic artery. If handled improperly, it may cause complications after anastomosis.Therefore, arterial conduit could be used in primary OLT, re-OLT and multiple-OLT. This study aimed to investigate the indications, methods and techniques with usage of arterial conduit for HA revascularization during adult OLT.Methods We reviewed 1200 patients of consecutive OLTs performed during 2000-2009 in the First Affiliated Hospital of Sun Yat-sen University. Of these patients, 48 recipients with artery variations received HA revascularization with usage of arterial conduit and special postoperative managements. The indications, methods, techniques, and the managements of postoperative complications in adult OLT with usage of arterial conduit for HA revascularization were analyzed.Results In 48 cases with artery bypass, the arterial conduit were anastomosed between donor hepatic artery and recipient infrarenal aorta (n=32), between donor hepatic artery and recipient suprarenal aorta (n=10), and between donor upper abdominal organ cluster artery and recipient suprarenal aorta (n=6). The technique was applied in 4% (48/1200 cases) of the whole OLTs performed in the same period, and the patency rate of the conduits was 100%. Forty patients (83.3%) survived, and the average survival time was 3.9 years. Eight patients (16.7%) died (all due to tumor recurrence),while the average survival time was 1.2 years. All these patients have not experienced artery-related complications in their survival time.Conclusions When recipient HA has variations or pathological changes in OLT, the donor artery should be anastomosed to recipient abdominal aorta with an arterial conduit to achieve satisfactory outcomes

    Full Text Available In the Japanese, Formosan and crab-eating monkeys, the dorsal metatarsal arteries and their lateral distal perforating branches were well developed and supplied, directly or via the catella plantaris distalis, the plantar digital arteries. In the black ape, the plantar digital arteries arose from the medial plantar artery. The plantar metatarsal arteries of these monkeys, including the black ape, arose from the catella plantaris proximalis or deep plantar arch and were classified into the superficial plantar metatarsal (sM, superficial plantar intermetatarsal (sI, deep plantar metatarsal (dM and deep plantar intermetatarsal (dI arteries in relation to the interosseous muscles and metatarsal bones.

  19. The physiological impact of the nonlinearity of arterial elasticity in the ambulatory arterial stiffness index

    International Nuclear Information System (INIS)

    The ambulatory arterial stiffness index (AASI) is claimed to be a new estimator for arterial rigidity. It was recently defined as one minus the slope of the linear regression of systolic to diastolic ambulatory pressure during 24 h. Although several reports testify its clinical relevance, the explanation of how this new index is conceptually associated with arterial stiffness remains controversial. In this work we hypothesize that nonlinear arterial elasticity is behind AASI physiological principles. To that end, random number generators were used to emulate arterial cross-sectional area (CSA) during 24 h. Pressure values were calculated using linear and nonlinear elasticity models for rigid and compliant arteries. The AASI was calculated from simulated pressures and also analytically predicted for each model. Additionally, invasive aortic pressure and CSA were continuously measured in a conscious sheep during 24 h to test the nonlinear model. We found that analytical solutions agreed with simulation outcomes; for the nonlinear model, the AASI was higher in rigid arteries with respect to compliant arteries (0.51 versus 0.38) and the linear model systematically predicted AASI = 0. For in vivo pressure measurements, AASI was 0.31. Using the measured pulsatile CSA and an estimation of the elastic constant for the nonlinear model, the AASI was accurately predicted with errors below 5%. We conclude that the AASI is higher in stiffer arteries due to the nonlinear behavior of the arterial wall. With a nonlinear arterial function, the slope of the linear regression of diastolic to systolic pressures during 24 h depends on the product of an elastic constant by the pulsatile CSA. As the elastic constant dominates the product, the reported associations between the AASI and arterial stiffness indices now have a consistent explanation

Among the South American species of Mathevotaenia, M. argentinensis is most similar to the new species by having similar body length and number of testes, but the major differences between both species include the size of suckers, neck, proglottids, testes and egg capsules, and the shape of the genital atrium and ovary (with 10-13 lobules on each side in M. argentinensis,, and 4-7 lobules in M. chaquensis n. sp.. A key to the species of the South American members of the Mathevotaenia Akumyan, 1946 is presented.Mathevotaenia chaquensis n. sp. (Cestoda, Anoplocephalidae, Linstowiinae es descrita parasitando al lagarto de los quebrachales, Tropidurus spinulosus, procedente de la Provincia del Chaco, Argentina. Esta es la segunda especie de Mathevotaenia descrita parasitando reptiles Neotropicales. La nueva especie está caracterizada principalmente por tener un estróbilo relativamente pequeño, 24 mm de largo, con aproximadamente 100 proglótides craspedotas y 19-24 testículos por proglótide. Entre las especies sudamericanas de Mathevotaenia, M. argentinensis es la más semejante a la nueva especie por presentar similar longitud del cuerpo y número de testículos, pero difieren en el tamaño de las ventosas, cuello, proglótides, testículos y huevos.

    We report a case of congenital absence of the cervical and petrous part of the left internal carotid artery, the middle and proximal part of the basilar artery, and the V4 segment of the left vertebral artery associated with a left persistent trigeminal artery and a coarctation of the aorta. The left cerebral vessels are supplied via the anterior communicating artery and the left persistent trigeminal artery. The coexisting coarctation of the aorta led to a subclavian steal phenomenon. The alteration of the cerebral hemodynamics has to be taken in consideration when performing cerebral angiography and surgical correction in such a case. (orig.)

    Full Text Available Unusual course and branching pattern of the tibial arteries were discovered during routine anatomical dissection of the right lower extremity of a 61-year-old female cadaver. The arteries of the crural region arose from the popliteal artery, as usual. However, the anterior tibial artery was hypoplastic and supplying the anterior calf muscles ended above the ankle joint. Instead, the posterior tibial artery gave off a large anterior branch, which crossed the lowest portion of the interosseous membrane and prolonged as the most distal continuation of the anterior tibial artery –the dorsalis pedis artery. The rest of the posterior tibial artery continued its course distally and divided into the usual medial and lateral plantar arteries. We briefly review the reported variations of the tibial arteries and discussed their clinical relevance.

  4. A Case of Incomplete Central Retinal Artery Occlusion Associated with Short Posterior Ciliary Artery Occlusion

    Full Text Available To our knowledge, incomplete central retinal artery occlusion associated with short posterior ciliary artery occlusion is extremely rare. Herein, we describe a case of a 62-year-old man who was referred to our hospital with of transient blindness in his right eye. At initial examination, the patient’s best-corrected visual acuity was 18/20 in the right eye. Fundus examination showed multiple soft exudates around the optic disc and mild macular retinal edema in his right eye; however, a cherry red spot on the macula was not detected. Fluorescein angiography revealed delayed dye inflow into the nasal choroidal hemisphere that is supplied by the short posterior ciliary artery. The following day, the patient’s visual acuity improved to 20/20. Soft exudates around the optic disc increased during observation and gradually disappeared. His hemodynamic parameters revealed subclavian steal syndrome as examined by cervical ultrasonography and digital subtraction angiography. We speculate that his transient blindness was due to ophthalmic artery spasms. In this particular case, spasms of the ophthalmic artery and occlusion of the short posterior ciliary artery occurred simultaneously. As the short posterior ciliary artery branches from the ophthalmic artery, the anatomical location of the lesion might be near the branching of both arteries.

  5. The new technique of using the epigastric arteries in renal transplantation with multiple renal arteries

    Full Text Available The most common anatomic variant seen in the donor kidneys for renal transplantation is multiple renal arteries (MRA, which can cause an increased risk of complications. We describe the long-term outcomes of 16 years of experience in 76 kidney transplantations with MRAs. In a new reconstruction technique, we remove arterial clamps after anastomosing the donor to the recipient′s main renal vessels, which cause backflow from accessory arteries to prevent thrombosis. By this technique, we reduce the ischemic times as well as the operating times. Both in live or cadaver donor kidneys, lower polar arteries were anastomosed to the inferior epigastric artery and upper polar arteries were anastomosed to the superior epigastric arteries. Injection of Papaverine and ablation of sympathic nerves of these arteries dilate and prevent them from post-operative spasm. Follow-up DTPA renal scan in all patients showed good perfusion and function of the transplanted kidney, except two cases of polar arterial thrombosis. Mean creatinine levels during at least two years of follow-up remained acceptable. Patient and graft survival were excellent. No cases of ATN, hypertension, rejection and urologic complications were found. In conclusion, this technique can be safely and successfully utilized for renal transplantation with kidneys having MRAs, and may be associated with a lower complication rate and better graft function compared with the existing techniques.

  6. Recanalization of superficial femoral artery by retrograde approach via popliteal artery

    International Nuclear Information System (INIS)

    To recanalize the occlusive lesion of superficial femoral artery at origin site by retrograde approach via popliteal artery. 15 patients, who were poor surgical candidates due to coronary artery disease and who had severe occlusive lesion of superficial femoral artery close to its origin with good distal runoffs to popliteal artery, were selected. Patients were all men and range of age were from 53 years to 66 years (mean age: 63 years). Range of lesion length were from 15 cm to 30 cm (mean length: 22.4 cm). Localization of popliteal artery was done with Doppler stethoscope or 'road-map' DSA. The method of recanalization were transluminal endarterectomy catheter (TEC), TEC and angioplasty, thrombolysoangioplasty (TLA). Retrograde puncture of popliteal artery was done in 15 patients successfully. TEC and PTA was performed in 9 patients, TEC only in 2 patients, and TLA and PTA in 2 patients. During the follow-up period of 5 months to 2 years reocclusion did not occur in 10 patients except for 1 patient with poor cardiac output in whom it occurred 1 day later. Remained 4 patients were lost in follow up. Any neurologic or vascular complication did not occur. Retrograde approach of superficial femoral artery via popliteal artery in patients with difficult vascular intervention by common method provides a useful, alternative recanalization method

  12. Transposition of the great arteries

    Directory of Open Access Journals (Sweden)

    Castela Eduardo

    2008-10-01

    Full Text Available Abstract Transposition of the great arteries (TGA, also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an isolated finding. In 10% of cases, TGA is associated with noncardiac malformations. The association with other cardiac malformations such as ventricular septal defect (VSD and left ventricular outflow tract obstruction is frequent and dictates timing and clinical presentation, which consists of cyanosis with or without congestive heart failure. The onset and severity depend on anatomical and functional variants that influence the degree of mixing between the two circulations. If no obstructive lesions are present and there is a large VSD, cyanosis may go undetected and only be perceived during episodes of crying or agitation. In these cases, signs of congestive heart failure prevail. The exact aetiology remains unknown. Some associated risk factors (gestational diabetes mellitus, maternal exposure to rodenticides and herbicides, maternal use of antiepileptic drugs have been postulated. Mutations in growth differentiation factor-1 gene, the thyroid hormone receptor-associated protein-2 gene and the gene encoding the cryptic protein have been shown implicated in discordant VA connections, but they explain only a small minority of TGA cases. The diagnosis is confirmed by echocardiography, which also provides the morphological details required for future surgical management. Prenatal diagnosis by foetal echocardiography is possible and desirable, as it may improve the early neonatal management and reduce morbidity and mortality. Differential diagnosis includes other causes of central neonatal cyanosis. Palliative treatment with prostaglandin E1 and balloon atrial septostomy are usually

    2007-01-01

    Arterial bifurcations are places where blood flow may be disturbed and slow recirculation flow may occur.To reveal the correlation between local oxygen transfer and atherogenesis, a finite element method was employed to simulate the blood flow and the oxygen transfer in the human carotid artery bifurcation. Under steady-state flow conditions, the numerical simulation demonstrated a variation in local oxygen transfer at the bifurcation, showing that the convective condition in the disturbed flow region may produce uneven local oxygen transfer at the blood/wall interface.The disturbed blood flow with formation of slow eddies in the carotid sinus resulted in a depression in oxygen supply to the arterial wall at the entry of the sinus, which in turn may lead to an atherogenic response of the arterial wall, and contribute to the development of atherosclerotic stenosis there.

  19. Cervical artery dissection following a turbulent flight.

    LENUS (Irish Health Repository)

    Quinn, Colin

    2012-01-31

    BACKGROUND: Cervical artery dissection is a common cause of stroke in young patients without vascular risk factors and may affect the carotid or vertebral arteries. The risk of spontaneous dissection is higher in those with genetic predisposing factors while other cases may be precipitated by an event involving head or neck movement or associated with direct neck trauma. CASE REPORT: We present the case of a previously well young woman with a history of migraine who developed internal carotid artery dissection following a turbulent short-haul commercial flight while restrained using a seatbelt. DISCUSSION: We propose that repetitive flexion-hyperextension neck movements encountered during the flight were the most likely precipitant of carotid artery dissection in this case and review the therapeutic options available.

    Directory of Open Access Journals (Sweden)

    A. Vonk-Noordegraaf

    2010-09-01

    Full Text Available The anatomical differences between the pulmonary and systemic arterial system are the main cause of the difference in distribution of compliance. In the pulmonary arterial system compliance is distributed over the entire arterial system, and stands at the basis of the constancy of the RC-time. This distribution depends on the number of peripheral vessels, which is ∼8–10 times more in the pulmonary system than the systemic tree. In the systemic arterial tree the compliance is mainly located in the aorta (80% of total compliance in thoracic-abdominal aorta. The constant RC-time in the pulmonary bed results in proportionality of systolic and diastolic pressure with mean pressure and, in turn, in the constant ratio of oscillatory and mean power.

  13. Atherosclerosis and the internal mammary arteries

    International Nuclear Information System (INIS)

    One hundred and fifty patients with coronary artery disease (CAD), 14 (9.3%) of whom had coexisting peripheral vascular disease, underwent bilateral internal mammary arteriography to study the incidence and extent of atherosclerosis in these vessels. Significant atherosclerosis of the internal mammary arteries (IMAs) was present in three patients (2%), of whom one had coexisting peripheral vascular disease. Lesions in the IMAs were found either proximally, close to the origin or distally, around the terminal bifurcation. Six of the 14 patients with peripheral vascular disease (4% of total subjects) had significant atherosclerosis of the brachiocephalic arteries. Atherosclerotic involvement of the IMA is very unusual and rarely interferes with the use of these vessels for coronary bypass. More common, however, is atherosclerosis of the subclavian arteries, a contraindication for IMA grafting if the lesion is proximal to the IMA origin. (orig.)

  14. Arterial segmental vasoconstriction in hypercholesterolaemic patients

    International Nuclear Information System (INIS)

    Regular, wave-like constriction in medium-sized arteries, arterial segmental vasoconstriction (ASV), has been observed at arteriography and described by many authors. We found ASV in arteriograms of the superficial femoral artery in 13 of 107 hypercholesterolaemic patients, enrolled in the Probucol Quantitative Regression Swedish Trial (PQRST). The arteriograms were digitized and studied with a quantitative computer-assisted technique. The frequency of ASV was higher than has been reported earlier in clinical materials, possibly because of an increased vasoreactivity in hypercholesterolaemia, as recently observed experimentally. The ASV patients were, on average, younger, had lower blood pressure and less atherosclerosis, than the non-ASV patients. ASV was not found in any of the 19 patients in the material who either had symptoms of peripheral vascular disease or arteriographically verified arterial occlusions. No significant correlations with smoking habits or serum cholesterol levels were found. A computer-based index of ASV and measurement of ASV wavelength are discussed. (orig.)

    Cervical artery dissection (CAD) represents an increasingly recognized cause of stroke and the most common cause of ischemic stroke in young adults. Many factors have been identified in association with CAD such as primary disease of arterial wall (fibrodysplasia) and other non-specific diseases related to CAD like Ehlers Danlos-syndrome IV, Marfan’s syndrome, vessel tortuosity. Moreover, an underlying arteriopathy which could be in part genetically determined, has been suspected. The rule of...

    International Nuclear Information System (INIS)

    Rupture of a splenic artery aneurysm, commonly associated with pregnancy is a rare and catastrophic event. We report here a case of a patient in her second pregnancy who presented with a short history of left hypochondriac and epigastric pain, followed by collapse at 32 weeks gestation. Sudden fetal distress lead to emergency caesarean delivery when splenic artery aneurysm rupture was diagnosed. With timely involvement of multidisciplinary personnel both mother and baby survived and had an uneventful recovery. (author)

    Full Text Available Susac's syndrome is a rare disease attribuited to a microangiopathy involving the arterioles of the cochlea, retina and brain. Encefalopathy, hearing loss, and visual deficits are the hallmarks of the disease. Visual loss is due to multiple, recurrent branch arterial retinal occlusions. We report a case of a 20-year-old women with Susac syndrome presented with peripheral vestibular syndrome, hearing loss, ataxia, vertigo, and vision loss due occlusion of the retinal branch artery.

    This second report in the series on coronary artery bypass presents the authors experience and personal views on the internal thoracic artery (ITA) which date to 1966. There has been a very gradual evolution in the acceptance of this conduit which was initially compared with the saphenous vein and viewed as an improbable alternative to it. As is common with concepts and techniques which are 'outside the box' there was skepticism and criticism of this new conduit which was more difficult and t...

    INTRODUCTION: Peripheral arterial disease (PAD) is a condition characterized by atherosclerotic occlusive disease of the lower extremities. While PAD is a major risk factor for lower-extremity amputation, it is also accompanied by a high likelihood for symptomatic cardiovascular and cerebrovascular disease. Atherosclerosis accounts for more than 90% of cases of PAD, and uncommon vascular syndromes account for the remaining 10%. The femoral and popliteal arteries are affected in 80% to 90% of ...

    Cardiovascular disease (CVD) is the leading cause of death globally and it is predicted this will remain to increase throughout 2030 to an estimated 23,3 million patients per year. This trend is accompanied by a steep increase in healthcare costs, making it a great health and socio-economic burden. The underlying pathology of CVD is often atherosclerosis, characterized by the development of atherosclerotic plaques in middle- and larger-sized arteries. Peripheral artery disease (PAD) is a dise...

    Cardiovascular disease is one of the leading cause of mortality in the US and especially, coronary artery disease increases with an aging population and increasing obesity. Currently, bypass surgery using autologous vessels, allografts, and synthetic grafts are known as a commonly used for arterial substitutes. However, these grafts have limited applications when an inner diameter of arteries is less than 6 mm due to low availability, thrombotic complications, compliance mismatch, and late intimal hyperplasia. To overcome these limitations, tissue engineering has been successfully applied as a promising alternative to develop small-diameter arterial constructs that are nonthrombogenic, robust, and compliant. Several previous studies have developed small-diameter arterial constructs with tri-lamellar structure, excellent mechanical properties and burst pressure comparable to native arteries. While high tensile strength and burst pressure by increasing collagen production from a rigid material or cell sheet scaffold, these constructs still had low elastin production and compliance, which is a major problem to cause graft failure after implantation. Considering these issues, we hypothesized that an elastometric biomaterial combined with mechanical conditioning would provide elasticity and conduct mechanical signals more efficiently to vascular cells, which increase extracellular matrix production and support cellular orientation. The objective of this report is to introduce a fabrication technique of porous tubular scaffolds and a dynamic mechanical conditioning for applying them to arterial tissue engineering. We used a biodegradable elastomer, poly (glycerol sebacate) (PGS) for fabricating porous tubular scaffolds from the salt fusion method. Adult primary baboon smooth muscle cells (SMCs) were seeded on the lumen of scaffolds, which cultured in our designed pulsatile flow bioreactor for 3 weeks. PGS scaffolds had consistent thickness and randomly distributed macro

    Full Text Available The aneurysmsatic changes of the infrapopliteal arteries are rarely seen. They are pseudoaneurysms rather than true aneursyms. The most important cause of them is trauma. There is not a standart treatment for infrapopliteal aneursyms. In this study, we have evaluated a case operated for anterior tibial artery pseudoaneurysm developed after penetrant trauma and diagnosed two weeks later. [Cukurova Med J 2012; 37(3.000: 172-175

  18. Hepatic artery pseudoaneurysm following laparoscopic cholecystectomy

    International Nuclear Information System (INIS)

    The authors describe a hepatic pseudoaneurysm following laparoscopic cholecystectomy in a child. It arose from a hepatic artery that was ligated during surgery and was supplied by collaterals from the superior right branch. Because of the risk of hepatic infarction and recanalization of the pseudoaneurysm by new collaterals, the authors decided not to occlude the superior right branch, but to embolize the aneurysm itself with cyanoacrylate. Since the intra-arterial approach was not feasible, a transhepatic puncture was successfully performed. (orig.)

    Unusual course and branching pattern of the tibial arteries were discovered during routine anatomical dissection of the right lower extremity of a 61-year-old female cadaver. The arteries of the crural region arose from the popliteal artery, as usual. However, the anterior tibial artery was hypoplastic and supplying the anterior calf muscles ended above the ankle joint. Instead, the posterior tibial artery gave off a large anterior branch, which crossed the lowest portion of the interosseous ...

    Abstract One of the primary forms of congenital anomalies of the coronary arteries is coronary artery fistula (CAF). It is defined as a direct communication between the coronary artery and any surrounding cardiac chamber or vascular structure, which bypasses the myocardial capillary bed. We present a newborn baby with a large coronary artery fistula connecting the left anterior descending (LAD) artery to the left ventricular (LV) apex. Associated cardiac abnormalities were found: a ventricula...
