Medicina Intensiva , 2006,
Abstract: La resincronización cardíaca es eficaz en pacientes con insuficiencia cardíaca y criterios de asincronía intraventricular. Sin embargo, durante el implante podemos encontrarnos excepcionalmente con la existencia inesperada de una vena cava izquierda persistente. Presentamos un caso de miocardiopatía dilatada en el que se implantó con éxito un dispositivo de resincronización, exclusivamente a través de una vena cava izquierda persistente no comunicada con la vena cava derecha. Cardiac resynchronization therapy is effective in the treatment of patients with severe heart failure and intraventricular dysynchrony. However, we are sometimes faced with the unexpected presence of a persistent left superior vena cava. We report the case of a patient with dilated cardiomyopathy and left ventricular dysynchrony in which we implanted a resynchronization pacemaker exclusively through a persistent left superior vena cava that did not communicate with the right vena cava.

Abstract: La vena cava superior izquierda persistente (VCSIP) es la anomalía congénita venosa deltórax más frecuente. Se encuentra en el 0,3% de la población general y en el 5-10% de lospacientes con cardiopatías congénitas. Generalmente evoluciona en forma asintomática yno genera trastornos hemodinámicos, pero su reconocimiento es importante, ya que puededificultar la introducción de catéteres para mediciones hemodinámicas, los implantes demarcapasos cardíacos (MCP) y de cardiodesfibriladores automáticos implantables (CDAI),especialmente cuando se utiliza la vía cefálica o la subclavia izquierda.En el caso clínico que se presenta se efectuó el implante de un CDAI bicameral vía VCSIP,descubierta durante el procedimiento. Asimismo, se muestran las características de estavariedad anatómica mediante tomografía cardíaca computarizada de 64 cortes (TCC64).REV ARGENT CARDIOL 2009;77:224-226.
Inserción accidental de catéter para hemodiálisis en vena cava superior izquierda persistente Accidental implantation of hemodialysis catheter in persistent left superior vena cava

Acta Medica Colombiana , 2007,
Abstract: La implantación de catéteres centrales para hemodiálisis en pacientes con falla renal es una práctica común. El acceso venoso por punción percutánea de la vena yugular interna es la ruta más recomendada debido a que genera el menor porcentaje de estenosis. La punción de la vena yugular interna derecha es la más conveniente por su trayecto vertical hacia la aurícula derecha, pero en ocasiones su canalización es imposible siendo necesario puncionar la vena yugular interna izquierda, la cual se continúa con la vena innominada desembocando en la cava superior, de ahí que su trayecto sea muy tortuoso. Se describen tres casos en los cuales el catéter yugular interno izquierdo que se insertó para realizar hemodiálisis, accidentalmente canalizó la vena cava superior izquierda anormalmente persistente. En todos los casos y antes de proceder con la hemodiálisis se demostró bien sea por gases del vaso puncionado, ecocardiograma o medio de contraste que el catéter se encontraba posicionado en el sistema venoso que drena en la aurícula derecha. The implantation of central catheters for hemodialysis in patients with renal failure is a common practice. The venous access to the internal jugular vein through percutaneous puncture is the most recommended procedure because it produces the lowest percentage of stenosis. The right internal jugular vein puncture is the most appropriate one because it goes directly in vertical direction into the right atrium, but in some cases its canalization is impossible making it necessary to puncture the left internal jugular vein, the one next to the innominated vein that ends in the superior cava, with the result that its path is much curved. 3 cases in which the left intern jugular catheter that was inserted to perform hemodialysis accidentally canalized the anomaly in the persistent left superior vena cava were presented. In all the cases and before proceeding with the hemodialysis it was demonstrated by the gases of the punctuated vessel, echocardiogram or contrast medium that the catheter was positioned in the venous system that drains in the right atrium.

Terapia de resincronización cardiaca en paciente con vena cava superior izquierda persistente: Caso clínico

Abstract: persistent left superior vena cava is the most common venous congenital malformation and is usually asymptomatic. its presence could increase the difficulty for transvenous lead implantation. we report a 71-year-old woman with an idiopathic dilated cardiomyopathy, atrial fibrillation and heart failure that required biventri-cular resynchronization therapy. during the placement of the device a persistent left superior vena cava was detected. the device was placed without problems and the patient had a satisfactory postoperative evolution.

Vena cava superior izquierda persistente: Implicaciones en la cateterización venosa central

Abstract: the placement of central catheters through the subclavian and jugular venous path can be complicated by the cannulation of an artery or an aberrant venous path. the most frequent anomaly of the embryological development of the caval vein is the persistence of the left superior vena cava (lsvc). the implantation of catheters in the lsvc can be suspected by its anomalous route in thorax radiography. gasometry and the pressure curve of the vessel make it possible to rule out an arterial catheterisation. diagnostic confirmation is obtained through angiography, echocardiography, computerised tomography or cardiac resonance. the doctor who regularly implants central venous catheters must be familiar with the anatomy of the venous system and its variants and anomalies, since their presence might influence the handling of the patient.

Abstract: persistent left superior vena cava (plsvc) is the most common congenital defect in the thoracic venous system, with an incidence of 0.3% in the general population and of 5-10% in patients with congenital heart disease. this asymptomatic condition does not produce hemodynamic impairment; however, it should be recognized as its presence poses technical challenges in the introduction of catheters for hemodynamic measurements and for placement of pacemakers (pms) and implantable cardioverter defibrillators (icd) via the cephalic vein or the left suclavian vein. in the present case report we describe the implantation of a dual-chamber icd through a plsvc discovered during the procedure. in addition, images from cardiac 64-row multidetector computed tomography (64-row ct) show the anatomic features of this variety.

Abstract: Persistent left superior vena cava and absent right superior vena cava is an uncommon anatomical association. This is a challenging situation for permanent pacemaker implantation. We report three patients with this anomaly and a permanent pacemaker successfully implanted through the left superior vena cava and coronary sinus, without acute or chronic complications

Abstract: La colocación de catéteres centrales por vía venosa subclavia y yugular se puede complicar con la canalización de una arteria o de una vía venosa aberrante. La anomalía más frecuente del desarrollo embriológico de la vena cava es la persistencia de la vena cava superior izquierda (VCSI). La implantación de catéteres en la VCSI se puede sospechar por el recorrido anómalo del mismo en la radiografía de tórax. La gasometría y la curva de presión del vaso permiten descartar una cateterización arterial. La confirmación diagnóstica se obtiene mediante angiografía, ecocardiografía, tomografía computerizada o cardio-resonancia. El médico que implanta habitualmente catéteres venosos centrales, debe estar familiarizado con la anatomía del sistema venoso, sus variantes y sus anomalías, ya que su presencia puede influir en el manejo del paciente.
