ABSTRACT

Objetivo: Presentar nuestra experiencia y analizar el pronóstico de pacientes COVID-19 con ictus isquémico agudo por oclusión de grandes vasos tratados con neurointervencionismo (NIV) en la unidad de ictus. Material y métodos: Se incluyeron todos los pacientes consecutivos con ictus isquémico agudo debido a oclusión de grandes vasos tratados por NIV en nuestra institución entre marzo y abril de 2020, durante el brote de COVID-19. Se realizó una comparación entre pacientes con COVID-19 y pacientes sin infección por coronavirus. Se comunican los resultados clínicos iniciales y a corto plazo. Resultados: Del 1 de marzo al 30 de abril se realizaron 25 procedimientos de NIV por ictus isquémico agudo en nuestra institución. Ocho pacientes eran COVID-19 y 17 eran pacientes no COVID-19. La edad media de los pacientes con COVID-19 fue de 70,1 ± 12,23 años, y 7 fueron hombres (87,5%, p = 0,006). Mientras que todos los pacientes sin COVID procedían de urgencias, solo 5 pacientes con COVID-19 (62,5%) fueron atendidos desde urgencias por ictus (p = 0,01). Tres pacientes procedían de hospitalización. La tasa de mortalidad en pacientes sin COVID-19 fue del 5,8%, pero en pacientes con COVID-19 fue considerablemente alta (50%). Ningún parámetro analítico difirió entre ambos grupos. No se registraron hemorragias en esta serie.En comparación con el mismo período del año pasado, se observó una disminución de la actividad neurointervencionista del 39%. Conclusiones: La mejor terapia médica y de NIV desembocó en malos resultados y una mortalidad dramática. La pandemia de COVID-19 dificultó significativamente el funcionamiento normal de los servicios de urgencias y la atención de estos pacientes con ictus.

ABSTRACT

OBJECTIVES: It is difficult to establish which patients suffering from critical lower limb ischaemia will benefit from revascularization. Risk scores can provide objectivity in decision making. The aim was to design a new risk score (ERICVA) and compare its predictive power with the PREVENT III and Finnvasc scores. METHODS: An observational retrospective study of patients who underwent revascularization (open or endovascular) in Valladolid's University Hospital between 2005 and 2010 was designed. The sample was divided into two subgroups (development and validation subsamples). After univariate analysis followed by a multivariate Cox regression, a number of variables associated with death and/or major amputation were selected, creating a weighed score called ERICVA, and a simplified version of it. The area under the curve (AUC) of receiver operating characteristic (ROC) curve analysis was performed and the AUC of these two scores were additionally compared with the AUC of the PREVENT III and Finnvasc scales. RESULTS: Six hundred and seventy two cases with an average surveillance of 778 days were included in the study. Amputation free survival (AFS) was 84.8% at 30 days and 63.1% at 1 year. Variables associated with death and/or major amputation in the Cox regression were cerebrovascular disease, prior contralateral major amputation, diabetes mellitus, dialysis, chronic obstructive pulmonary disease, cancer, haematocrit less than 30%, neutrophil/lymphocyte ratio exceeding 5, absence of arterial Doppler signal at the ankle, emergency admission, and Rutherford stage 6; these variables were used for the ERICVA and simplified ERICVA score designs. Scores were applied to both subsamples; in the development sample the AUC of ERICVA and simplified ERICVA was significantly higher than the PREVENT III (p = .008 and p = .045) and Finnvasc (p < .0001 and p = .0013) scores; in the validation sample the AUC of ERICVA and simplified ERICVA were significantly higher than Finnvasc score (p = .0323 and p = .0017). CONCLUSIONS: The ERICVA model has a good predictive capacity for death and/or major amputation in the clinical setting, and is better than the PREVENT III and Finnvasc scores.

ABSTRACT

OBJECTIVE: Calcifying nanoparticles (NPs) have been detected recently in calcified human arterial specimens and are involved in the process of calcification. This study was designed to test the hypothesis that human-derived NPs could worsen the response to arterial endothelial injury and induce vascular calcification. METHODS: The right carotid artery of 24 New Zealand rabbits was injured with an angioplasty balloon. Animals were perfused intravenously with saline (100 mL) during the experiment and divided into three groups: group-A, control; group-B, exposed to NPs (2 mL) obtained from calcified aortic valves; and group-C, exposed to NPs (2 mL) and treated postoperatively with atorvastatin (2.5 mg/kg/24 h). At 30 days, both carotid arteries were removed and examined histologically. Blood measurements were monitored during the study. RESULTS: The intimal hyperplasia area was significantly larger in the injured right carotid artery compared with the left unoperated carotid artery in all groups. There was no significant variation in medial area between groups. Morphometrically, the intima/media ratio (IMR) was significantly higher in damaged carotids compared with controls. A significant increase of IMR was found in group-B (1.81 ± 0.41) compared with group-A (0.38 ± 0.59; p = .004) or group-C (0.89 ± 0.79; p = .035). Differences between groups C and A were not significant (p = .064). Calcifications were observed in six animals, all of which had been exposed to NPs (4 in group-B, 2 in group-C, p = .027). Plasma levels of cholesterol and triglycerides remained stable. CONCLUSIONS: This research confirms the ability of systemic inoculation of human-derived NPs to accelerate hyperplasia and stimulate calcification in localized areas of arteries previously submitted to endothelial damage, while it was harmless in healthy arteries. Atorvastatin was demonstrated to slow down this process.

ABSTRACT

Introducción: El octreótido es un análogo sintético activo de la somatostatina que marcado con indio-111 tiene la capacidad de unirse a sus receptores, especialmente presentes en células neuroendocrinas. El objetivo es evaluar la utilidad de la gammagrafía de receptores de somatostatina (GRS) para la detección de recurrencias o restos tumorales de paragangliomas carotídeos. Material y métodos: Fueron considerados para análisis 29 casos tratados en 26 pacientes entre enero de 1996 y diciembre de 2010. Los estudios de GRS fueron comparados con angio-TC, así como los hallazgos clínicos y patológicos. Se registraron las variables demográficas, técnicas terapéuticas y los datos de seguimiento. Resultados: Mediana de edad de 68 años (r-27-82), 76,9% mujeres, resección completa del tumor glómico con reconstrucción vascular en 2 casos, endarterectomía carotídea en 3 y embolización preoperatoria en 3 casos. No se registró mortalidad perioperatoria. Tras una mediana de seguimiento de 5,8 ± 3,9 años, la lesión neurológica fue la complicación más frecuente (un nervio hipogloso, disfonía en 2 casos y glosofaríngeo en otro). El estudio GRS fue posible en 17 pacientes (mortalidad 19,2% [5], pérdida de seguimiento 15,4% [4]). Uno de los pacientes mostró hallazgos anormales en el estudio que no fueron detectados con angio-TC, confirmándose quirúrgicamente una recidiva local. Conclusiones: La GRS es una técnica útil para la detección de tumores neuroendocrinos primarios y metastásicos. Esta técnica permite la distinción entre paragangliomas carotídeos y otros tumores de cabeza y cuello, siendo válida para el seguimiento postoperatorio y la detección de recurrencias (AU)


Introduction: Octreotide is an active synthetic analogue of Indium-111-labelled somatostatin. It has the ability to bind to their receptors, especially present in neuroendocrine cells. The objective is to evaluate the usefulness of somatostatin receptor scintigraphy (GRS) for the detection of recurrences or residual tumours of carotid paragangliomas. Material and methods: A total of 29 cases in 26 patients treated between January 1996 and December 2010 were considered for analysis. GRS studies were compared with CT angiography and the clinical and pathological findings. We recorded demographic, therapeutic techniques and monitoring data. Results: Mean age 68 years (r-27-82), 76.9% female, complete resection of glomus tumour with vascular reconstruction in 2 cases, CEA in 3 patients, and preoperative embolization in three cases. There was no perioperative mortality. After a mean of 5.8±3.9 years, neurological injury was the most common complication (hypoglossal nerve injury in one case, dysphonia in two cases, and glossopharyngeal injury in another). The GRS study was possible in 17 patients (19.2% mortality, 15.4% lost to follow-up). One of the patients showed abnormal findings in GRS study that were not detected in CT; confirmed surgically as a local recurrence. Conclusions: The GRS is a useful technique for the detection of primary and metastatic neuroendocrine tumours. This technique helps to distinguish between carotid paragangliomas and other head and neck tumours, and is valid for the monitoring and detection of postoperative recurrence (AU)

ABSTRACT

La Distrofia Simpático Refleja (DSR), o Distrofia de Südeck, es una entidad patológica poco estudiada, infradiagnosticada, con graves consecuencias y que altera la calidad de vida de los pacientes que la padecen. Ha recibido otras denominaciones históricas como Causalgia (mayor o menor), aunque en la actualidad se le denomina Síndrome de Dolor Regional Complejo (SDRC), también conocido como CRPS por sus siglas en inglés (Complex Regional Pain Syndrom). Este cuadro clínico se divide en dos tipos: 1/ SDRC tipo I o Distrofia Simpático Refleja, y 2/ SDRC tipo II o Causalgia. La diferencia entre ellos radica en la lesión del nervio, que es objetivable únicamente en el tipo II. El síntoma clave que define a esta enfermedad es la presencia de un intenso y persistente dolor, de causa inexplicable, junto con disestesias y alodinia térmica. Su diagnóstico es básicamente clínico, acompañado de sus antecedentes, generalmente traumáticos, así como algunos estudios radiológicos complementarios. En cuanto a la terapéutica de esta enfermedad, es necesario combinar tanto la fisioterapia como tratamientos farmacológicos y psicológicos (AU)


Reflex Sympathetic Dystrophy (RSD), or Südeck dystrophy is a pathological entity understudied, underdiagnosed, with serious consequences and impaired quality of life for patients who suffer. It has received other mainline denominations as causalgia (major o minor), but today is called Complex Regional Pain Syndrome, also known as CRPS for its acronym in English. This clinical disease is divided into two types: 1 / CRPS Type I or Reflex Sympathetic Dystrophy, and 2 / CRPS type II or causalgia. The difference between them is nerve damage, which is objective only in type II. The key symptom that defines this disease is the presence of an intense and persistent pain, unexplained, along with dysesthesia and thermal allodynia. Diagnosis is mainly clinical, accompanied by his background, usually traumatic, and additional radiologic studies. As for the treatment of this disease, it is necessary to combine both physiotherapy as pharmacological and psychological treatments (AU)

ABSTRACT

El cuidado minucioso del pie diabético es vital para prevenir infecciones y complicaciones como amputaciones y sepsis. Su manejo debe consistir en un abordaje multidisciplinar en el que el eje central sea la prevención así como la valoración y el tratamiento integral individualizado del paciente. En los últimos años, se ha evidenciado que terapias aplicadas hasta entonces a otros campos, podrían ser empleadas en el pie diabético, constituyendo un aumento del arsenal terapéutico que debe tener como finalidad combatir la infección y preservar la extremidad del paciente. Analizamos la eficacia, resultados clínicos y los costes de estas nuevas terapias, especialmente la terapia con presión negativa (TPN), la oxigenoterapia hiperbárica, el tratamiento con factores de crecimiento-terapia celular, apósito modulador de proteasas, la terapia eléctrica y los suplementos dietéticos (AU)


The meticulous care of the diabetic foot is vital to prevent infection and complications such as amputations and sepsis. Its management should be a multidisciplinary approach in which the central axis is the prevention and the assessment and individualized comprehensive treatment of the patient. In recent years, has shown that therapies applied previously to other fields, could be used in the diabetic foot, constituting an increase in the therapeutic arsenal should be designed to fight infection and preserve the patient's limb. We analyze the effectiveness, clinical outcomes and costs of these new therapies, especially negative pressure therapy (NPT), hyperbaric oxygen therapy, treatment with growth factors, cell therapy, protease modulating dressings, electrical therapy and the nutritional supplements (AU)

ABSTRACT

El Síndrome de Tousseau se considera un síndrome paraneoplásico caracterizado por distintos eventos trombóticos, tanto rteriales como venosos, que pueden originarse tras el desarrollo de una enfermedad neoplásica o como signo premonitorio de la existencia de un cáncer oculto. La presencia de sucesos trombóticos idiopáticos nos debe alertar de la posible sospecha neoplásica. Una serie de pruebas diagnósticas son recomendables en estas circunstancias, tales como marcadores tumorales y ecografía abdomino-pélvica. Este síndrome conlleva un mal pronóstico en la evolución del proceso neoplásico, especialmente en los casos de trombosis arterial. A pesar de su relevancia clínica, alta incidencia de nuevas neoplasias y su pronóstico nefasto, esta patología sigue siendo bastante desconocida. En esta revisión se analiza su fisiopatología, las medidas terapéuticas antitrombóticas y modelos predictivos de riesgo, enfatizando la necesidad de nuevos estudios de investigación para una mayor comprensión de este síndrome (AU)


Tousseau Syndrome is regarded as a paraneoplasic syndrome characterized by thrombotic events, both arterial and venous occlusions, which can be originated after the development of a neoplasic disease or as a premonitory sign of the existence of a hidden cancer. The presence of thrombotic idiopathic events must warn us about the possible neoplasic suspect. A series of diagnostical studies are advisable in these circumstances, such tumoral markers and abdomino-pelvical ultrasound scan. This syndrome involves a bad prognosis in the evolution of the neoplasic process, especially in cases of arterial thrombosis. In spite of its clinical relevance, high incidence of new neoplasias and an ill-fated prognosis, this pathology continues to be unknown enough. In this revision its fisiopathology, the therapeutic antithrombotic treatment, and the risk predictive models are discussed, emphasizing the necessity of new research studies for a bigger understanding of this syndrome (AU)

ABSTRACT

INTRODUCTION: Synchronous embolism to the superior mesenteric artery (SMA) and coeliac axis (CA) is a rare disease. REPORT: A 67-year-old man with atrial fibrillation developed acute liver failure due to an embolic occlusion of the CA and SMA, with a severe coagulation disorder. He was successfully managed with percutaneous stent placement and an exploratory laparotomy was not needed. He remains symptom-free 1 year after the procedure, and duplex follow-up showed stent patency. CONCLUSION: Endovascular techniques in patients with liver failure, no signs of peritonism, early diagnosis and high operative risk seem feasible and should be used if possible, as first-line option.

ABSTRACT

AIM: The aim of this paper was to determine the prevalence of extracraneal carotid artery disease in patients with intermittent claudication, to describe classic cardiovascular risk factors in those with hemodynamically significant stenosis and to try to define subgroups at high risk, improving therefore the performance of non invasive testing. METHODS: A prospective descriptive study was conducted, with 146 patients reporting an intermittent claudication of the lower limbs and without a previous cerebrovascular event or carotid surgery. An ultrasonography examination was done. Risk factors were registed (smoking, dislipemia, arterial hypertension, diabetes mellitus), also ischemic cardiopathy and myocardial revascularization procedures. Univariate and multivariate analysis was made to define the variables associated with hemodynamically significant stenosis. RESULTS: Prevalence of hemodynamically significant stenosis was 23.2%. Smoking, dislipemia, arterial hypertension and diabetes mellitus were not significantly associated with carotid stenosis; 24.2% of patients affected of ischemic cardiopathy present a severe stenosis, and myocardial revascularization was a risk factor for carotid stenosis. CONCLUSION: Patients with claudication and ischemic miocardiopathy, especially when myocardial revascularization is needed, must be explored with carotid ultrasonography. In this patients, probably of hemodynamically significant carotid stenosis that requires treatment is more frequent.

ABSTRACT

El fenómeno de Raynaud es un proceso vasoespástico que afecta típicamente a las partes acras de las extremidades en respuesta al frío o a estímulos mecánicos o emocionales. Este fenómeno se clasifica como primario cuando no se evidencia una causa subyacente, y secundario cuando existe una entidad patológica asociada. Esta distinción es importante pues condiciona el pronóstico, la gravedad y el tratamiento. Fisiológicamente, el equilibrio vasomotor se mantiene por complejas interacciones entre el endotelio, músculo liso y el sistema nervio autónomo que inerva los vasos. En esta revisión se analizan los mecanismos implicados en su desregulación, así como las diversas aproximaciones terapéuticas de acuerdo con la evidencia médica más reciente (AU)


Raynaud´s phenomenon is a vasospactic process that typically affects the acral parts of the limbs in response to cold or emotional or mechanical stimuli. This phenomenon is classified as primary when no evidence of an underlying cause, and secondary when there is an associated pathological entity. This distinction is important because it determines the prognosis, severity and treatment. Physiologically, the vasomotor balance is maintained by complex interactions between endothelium, smooth muscle and autonomic nervous system innervates the vessels. This review discusses the mechanisms involved in deregulation, and the various therapeutic approaches according the latest medical evidence (AU)

ABSTRACT

INTRODUCCIÓN. El síndrome compartimental abdominal (SCA) continúa siendo actualmente una complicación que asocia una importante morbi-mortalidad en el paciente vascular. El objetivo de nuestro trabajo es revisar la bibliografía científica para actualizar pautas de manejo del SCA y las consecuencias asociadas. MATERIAL Y MÉTODOS. Se realizó una revisión de la literatura científica de los últimos años que versa sobre el manejo diagnóstico y terapéutico del SCA además del abdomen abierto tras laparotomía descompresiva. Para ello se utilizó la base de datos de la Nacional Library of Medicine (PubMed). El estudio se limitó a trabajos publicados en los últimos 10 años en inglés y español que dispusieran de abstract on-line. Las palabras clave introducidas para la búsqueda fueron abdominal compartment symdrome, vascular surgery, ruptured aneurysm. RESULTADOS. Con dichos parámetros de búsqueda aparecen 84 trabajos de los cuales, 46 de ellos hacen referencia directa o indirecta mientras que los 38 trabajos restantes fueron desechados por no ajustarse a la finalidad de la búsqueda. De los trabajos recogidos se analizaron detenidamente 16 de ellos, a los cuales se hace referencia en el artículo de acuerdo al orden de aparición. CONCLUSIONES. El paciente sometido a cirugía vascular abdominal presenta alto riesgo para desarrollar el SCA por ello se debería monitorizar la presión intraabdominal en el ingreso en la unidad de cuidados intensivos tras la cirugía. La descompresión quirúrgica debería reservarse para aquellos pacientes con SCA refractario al tratamiento médico intensificado, utilizando un sistema de cierre asistido por vacío (VAC) como primera elección siempre que fuera posible (AU)


INTRODUCTION. The abdominal compartmental syndrome (SCA) is a complication that associates an important morbi-mortality in the vascular patient. The objective of our paper is to review the scientific bibliography in order to modernize rules of management of the SCA and the associated consequences. MATERIAL AND METHODS. We reviewed the scientific literature of the last years that deal with diagnosis and therapeutic of the SCA. We used the data base of the National Library of Medicine (PubMed). The study was limited to articles published in 10 last years, in English and Spanish language that they have an abstract on-line. The key words introduced for the search was abdominal compartment symdrome, vascular surgery, ruptured aneurysm. RESULTS. With these parameters we found 84 works, 46 of them makes direct reference to our aim while the 38 remaining works were discarded by not adjusting to the purpose of the search. 16 of them were analyzed. CONCLUSIONS. The vascular patient presents high risk in order to develop the SCA for it would be monitorized the intraabdominal pressure in the unit of intensive cares after the surgery. The surgical decompression should reserve for those patient with refractory SCA to the medical treatment, using a system of vacuum assisted closure (VAC) whenever it is possible (AU)

ABSTRACT

Introducción: El síndrome de atrapamiento de la arteria poplítea (SAAP) es una entidad pocofrecuente cuya incidencia varía del 0,17 al 3,5 %.Objetivo: Revisamos a los pacientes tratados quirúrgicamente en nuestro servicio durante losúltimos 15 años.Material y métodos: Estudio retrospectivo entre 1995 y 2009, en que se registraron variablesdemográfi cas, comorbilidad, clínica, exploración física, pruebas complementarias, tratamientoquirúrgico realizado, así como evolución a los 15 años.Resultados: Se intervino quirúrgicamente a 8 pacientes (el 50 %, varones) por SAAP con una medianade edad de 41,5 (intervalo, 16-62) años; 2 pacientes (25 %) presentaron claudicación invalidante,5 (62,5 %), dolor de reposo y en 1 caso (12,5 %), lesiones trófi cas. La prueba de elecciónen todos ellos fue la arteriografía, aunque también en 2 casos se realizó TC y en 3, angio-RM. Eltratamiento quirúrgico fue miotomía con liberación de la arteria poplítea en 3 pacientes (37,5 %)(en uno de ellos se asoció injerto venoso), miotomía junto a trombectomía poplítea en 2 pacientes(25 %), bypass poplíteo-poplíteo con vena en otros 2 (25 %) y un caso de simpatectomía lumbar(12,5 %). La arteriografía intraoperatoria fue normal. Durante el seguimiento a 15 años (medianade seguimiento 7,5 ± 3,98 años) el 50 % de los pacientes estaba asintomático, el 25 %presentaba claudicación no invalidante y otro 25 % falleció como consecuencia de su afecciónconcomitante.Conclusiones: En nuestra experiencia, la liberación de la arteria poplítea mediante miotomíadel tendón de inserción anómalo, asociada o no a la realización de un bypass poplíteo-poplíteo,es el tratamiento quirúrgico de elección(AU)


Introduction: Popliteal artery entrapment syndrome (PAES) is a rare condition with an incidencethat varies from 0.17-3.5 %.Aim: We reviewed patients treated with surgery in our department over the past 15 years.Material and methods: A retrospective study between 1995-2009 recorded demographicvariables, comorbidity, physical examination, diagnostic tests, surgical treatment and outcomeat 15 years.Results: Eight patients (50 % male) were treated with surgery for PAES, with a mean age41.5 years (range, 16-62). Two patients (25 %) had disabling claudication, 5 (62.5 %) pain at rest,and in one case (12,5 %) trophic lesions. The test of choice in all of them was arteriography,although two patients also had a CT and three an angio-MR. Surgery was myotomy with releaseof the popliteal artery in three patients (37.5 %) (one of them involving vein graft), myotomywith popliteal thrombectomy in two patients (25 %), popliteal-popliteal bypass with vein inanother 2 (25 %), and one case of lumbar sympathectomy (12.5 %). Intraoperative arteriographywas normal in all cases. During follow-up to 15 years (mean 7.5 ± 3.98 years), 50 % of patientswere asymptomatic, 25 % had no disabling claudication, and another 25 % died as a result ofdisease.Conclusions: In our experience, the release of the popliteal artery by myotomy abnormal tendoninsertion, with or without conducting a popliteal-popliteal bypass, is the surgical treatment ofchoice(AU)

ABSTRACT

Introducción. Poco se conoce sobre el impacto del síndrome postrombótico (SPT) en la calidadde vida (CV) de los pacientes.Objetivos. Evaluar la CV a largo plazo en pacientes con trombosis venosa profunda (TVP) de losmiembros inferiores y examinar si ésta se correlaciona con el nivel de gravedad del SPT.Material y métodos. Todos los pacientes incluidos fueron consecutivos, con síntomas unilateralesy primer episodio de TVP. Tras 5 años de seguimiento, el grado de secuela postrombótica fuevalorado mediante la escala de Villalta. Al fi nalizar todos realizaron un cuestionario genérico(EuroQol) y otro específi co de insufi ciencia venosa (CIVIQ). Los resultados fueron analizados demanera ciega.Resultados. De 165 pacientes inicialmente reclutados, tan sólo 100 completaron el seguimientode 5 años y cumplimentaron los cuestionarios. A pesar del uso regular de medias elásticas (75 %),la incidencia de SPT fue del 65 %: 35 pacientes asintomáticos, 41 pacientes con SPT moderado y24 pacientes con SPT grave. La CV media con el EuroQol y el CIVIQ fue, respectivamente, de91,5 % y 89,46 % en SPT ausente; 85,9 % y 74,43 % en SPT moderado; 58,2 % y 49,82 % en SPT grave.El EuroQol tan sólo mostró diferencias signifi cativas cuando el SPT fue grave, mientras queel CIVIQ se reveló muy útil para detectar diferencias entre los distintos subgrupos, mostrando undeterioro progresivo en relación con el nivel de gravedad del SPT (r = 0,601).Conclusiones. Los pacientes con TVP que desarrollan SPT presentan un importante deterioro dela CV, tanto peor cuanto más grave sea la secuela postrombótica(AU)


Introduction. Little is known about the impact of the posthrombotic syndrome (PTS) on thequality of life (QoL) of patients after deep vein thrombosis (DVT).Objective. The aims of this study were to analyze the long-term QoL after DVT and to examinewhether QoL correlates with the severity of PTS.Material and methods. Patients with previous symptomatic, unilateral, and a fi rst episode ofDVT were enrolled in this study. After 5 years of follow-up, the venous disease was related topathological severity of PTS according to the scale of Villalta. All patients then completed ageneric (EuroQol) and a disease-specifi c one for venous insuffi ciency (CIVIQ) questionnaires. Theanalysis of results was blinded to clinical details of the patients.Results. Of the 165 patients initially recruited, 100 patients completed the follow-up andcompleted the QoL assessment at 5 years. Despite the regular use of compression stockings theincidence of PTS was 65 %: 35 asymptomatic, 41 with moderate-PTS, and 24 with severe-PTS.The mean QoL with the EuroQol and the CIVIQ was 91.5 % and 89.46 % in absent-PTS; 85.9 % and74.43 % in moderate-PTS; and 58.2 % and 49.82 % in severe-PTS, respectively. The EuroQol onlyshowed signifi cant differences when the PTS was severe, while the CIVIQ was useful to detectdifferences among the different subgroups. These scores worsened signifi cantly with increasingseverity of PTS (r = 0.601).Conclusions. Patients with DVT in whom PTS develops have a worse QoL than those without PTS.Patient-based QoL measures correlated well with the severity of PTS(AU)

Introduction. The superior vena cava syndrome (SVCS) is caused by the diffi culty of venousreturn mainly due to malignant tumour pathology, and less commonly due to benign aetiology(pacemakers, indwelling catheters, etc.).Objective. We reviewed our experience in the endovascular treatment of this syndrome and itstherapeutic management.Patients and methods. Between 1998 and 2008 a total of 13 endovascular procedures(percutaneous transluminal angioplasty and self-expandable stent) were performed on patientswith SVCS, 10 (77 %) of whom were male and three (23 %) females, mean age 63.5 ± 13 years(42-80). The cause was lung cancer in 6 cases of (46.2 %), one case of oesophageal carcinoma(7.6 %), three mediastinal metastases (23.1 %) and three due to a central line for chemotherapy(23.1 %).Results. The endovascular procedure was optimal in 12 cases, resulting in migration of the stentin one case. The approach was femoral in 10 cases (77 %) and brachial in three (23 %). Localanaesthesia was used in 11 patients (84.6 %), two (15.4 %) with general anaesthetic due tosystemic problems. No patients died in relation to the intervention. Clinical improvement wasimmediate. During the 10 years follow up, 7 patients died from progression of their disease andtwo recurrences (15.4 %) were observed and treated with angioplasty. The survival rate of theseries was 46.2 %.Conclusions. Endovascular treatment of SVCS is a safe and effective procedure that providesrapid improvement in quality of life of patients and the compressive symptoms. The optimalanticoagulation regimen must be defined(AU)

ABSTRACT

Introducción. Los factores ambientales habitualmente se han relacionado con la rotura de aneurismas de aortaabdominal (AAA). El objetivo de este estudio es analizar su influencia con la posible estacionalidad y rotura de losAAA. Pacientes y métodos. Se diseñó un estudio ecológico retrospectivo estratificado por estaciones utilizando una seriede 106 AAA rotos registrados durante el periodo 2000-2007 y confirmados mediante tomografía computarizada y cirugía.Como variables ambientales se registraron la presión atmosférica, temperatura y humedad relativa al día de la rotura,así como la fase lunar correspondiente a ese día. Todos estos datos fueron facilitados y procesados por el Centro MeteorológicoRegional. Resultados. La edad media de la serie fue de 73 años (rango: 50-91 años), con un predominio francode varones (98,1%). La tasa de mortalidad global fue del 58,5%. Mediante un histograma de frecuencias se observóuna mayor incidencia de AAA rotos en otoño (32,1%). La única variable que presentó diferencias estadísticamente significativas(p < 0,05) entre los días de rotura y de no rotura fue la temperatura en las estaciones de invierno (1,5 ºC mayoren los días de rotura de AAA), verano (3 ºC mayor en los días de rotura de AAA) y otoño (1,5 ºC menor en los días de roturade AAA). No se encontraron diferencias significativas entre los días de rotura y no rotura para las variables de presióny humedad en ninguna de las estaciones. Una mayor frecuencia de roturas se apreció en cuarto creciente (29,2%),aunque el tamaño muestral pudo limitar la significación estadística con respecto al resto de fases lunares. Conclusiones.Aunque existe un fenómeno de estacionalidad, nuestra serie sólo confirma asociación estadística de la temperatura ambientalcon la rotura de AAA para nuestra región geográfica. Probablemente un mayor tamaño muestral podría arrojarresultados más concluyentes respecto a las otras variables analizadas(AU)


Introduction. Environmental factors have commonly been related with the rupture of abdominal aorticaneurysms (AAA). The aim of this study is to analyse their influence on the possible seasonality and rupture of AAA.Patients and methods. A retrospective ecological study, stratified by seasons, was designed drawing on a series of 106cases of ruptured AAA recorded over the period 2000-2007 and confirmed by means of computerised tomography andsurgery. Atmospheric pressure, temperature and relative humidity on the day of the rupture, and the phase of the moon onthat same day, were recorded as environmental variables. All these data were provided and processed by the RegionalMeteorological Centre. Results. The mean age of the series was 73 years (range: 50-91 years), and there was a clearpredominance of male patients (98.1%). The global rate of mortality was 58.5%. A histogram of frequencies revealed ahigher incidence of AAA ruptures in autumn (32.1%). The only variable that showed statistically significant differences(p < 0.05) between the days of rupture and non-rupture was the temperature in winter (1.5°C higher on the days whenrupture of AAA occurred), summer (3°C higher on the days when rupture of AAA occurred) and autumn (1.5°C lower onthe days when rupture of AAA occurred). No significant differences were found between days of rupture and non-rupturefor the variables pressure and humidity in any of the seasons. A higher frequency of ruptures was noted in the firstquarter (29.2%), although the sample size may have limited the statistical significance with respect to the other phases ofthe moon. Conclusions. Although a seasonality phenomenon does exist, our series only confirms a statistical associationbetween the environmental temperature and the rupture of AAA for our geographical region. A larger sample could probablyyield more conclusive results with respect to the other variables that were analysed(AU)

ABSTRACT

OBJECTIVES: Leucocyte infiltration in the wall of varicose veins has been reported previously. This study was designed to investigate the expression of pro-inflammatory cytokines and chemokines in control and in patients with varicose veins and to test the effect of treating varicose vein patients with acetylsalicylic acid (ASA) on cytokine expression prior to removal of varices. MATERIAL AND METHODS: Sections of vein were removed during operation from both patient groups, and ribonuclease protection assays (RPAs) were performed to assess the expression of chemokines. Group I included non-varicose saphenous veins from healthy patients undergoing amputation for trauma. Varicose veins were obtained from patients with primary varicose undergoing surgical treatment who received no drug (group II) or treatment with 300 mg day(-1) of ASA for 15 days before surgery (group III). RESULTS: Non-varicose veins constitutively expressed low levels of monocyte-chemoattractant protein (MCP-1) and interleukin (IL)-8 mRNA. Varicose veins had a distinct chemokine expression pattern, since significant up-regulation of MCP-1 and IL-8 and a marked expression of IP-10, RANTES, MIP-1alpha and MIP-1beta mRNA were detected. Removal of the endothelium did not alter this pattern. Varicose veins obtained from patients treated with ASA showed a consistent decrease in chemokine expression, although it did not reach statistical significance. CONCLUSIONS: Varicose veins showed increased expression of several chemokines compared to control veins. A non-significant reduction of activation was observed following treatment with ASA for 15 days.
