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

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

El síndrome compartimental agudo en el postoperatorio de cirugía cardiaca bajo circulación extracorpórea y especialmente tras revascularización miocárdica quirúrgica, es una complicación grave que se presenta de manera excepcional en las primeras horas del postoperatorio, requiere para su diagnóstico un alto nivel de sospecha y precisa de actuación quirúrgica urgente. Presentamos un caso de síndrome compartimental en la extremidad inferior de un paciente afecto de patología valvular aórtica degenerativa y enfermedad coronaria asociada, sometido a remplazo valvular por prótesis y bypass aortocoronario con injertos venosos y arterial, con especial atención hacia el mecanismo fisiopatológico que desencadena esta grave complicación, necesidad de un diagnóstico preciso y precoz y atención quirúrgica inmediata (AU)


Acute compartmental syndrome in the postoperative period of cardiac surgery with cardiopulmonary bypass, especially aftercoronary artery bypass graft surgery is a severe complication that rarely occurs during the firsts hours after surgery; diagnosis requires a high level of suspicion and emergency surgical treatment. We report a case of compartmental syndrome of lower extremity in a patient with degenerative aortic valve disease and associated coronary disease, who underwent valve replacement and aortocoronary bypass with venous ad arterial grafts, pointing at the pathophysiological mechanisms that triggers this serious complication, and the need for early and accurate diagnosis and inmmediate surgical management (AU)

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)

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)
