Catéter en vena cava superior para hemodiálisis entre los últimos recursos en hemitórax superior

César Augusto Restrepo Valencia; C.M. Buritica Barragán; A. Arango

We report four patients with chronic kidney disease undergoing haemodialysis therapy, which had exhausted conventional venous access (internal jugular, subclavian) and non-conventional access (axillary, innominate) in the upper hemithorax for haemodialysis. This was primarily due to thrombosis of these veins caused by previous catheterisation. These patients did not qualify for peritoneal dialysis. Using the technique recommended by Archundia et al., 4 indwelling catheters were implanted directly in the superior vena cava in each of the patients with subsequent subcutaneous tunneling. The catheters operated correctly and are currently permeable after being used for an average of 19 months.

Hemodialysis catheter implantation in the axillary vein by ultrasound guidance versus palpation or anatomical reference.

Background We compared the results of four different methods of hemodialysis catheter insertion in the medial segment of the axillary vein: ultrasound guidance, palpation, anatomical reference, and prior transient catheter. Methods All patients that required acute or chronic hemodialysis and for whom it was determined impossible or not recommended either to place a catheter in the internal jugular vein (for instance, those patients with a tracheostomy), or to practice arteriovenous fistula or graft; it was then essential to obtain an alternative vascular access. When the procedure of axillary vein catheter insertion was performed in the Renal Care Facility (RCF), ultrasound guidance was used, but in the intensive care unit (ICU), this resource was unavailable, so the palpation or anatomical reference technique was used. Results Two nephrologists with experience in the technique performed 83 procedures during a period lasting 15 years and 8 months (from January 1997–August 2012): 41 by ultrasound guidance; 19 by anatomical references; 15 by palpation of the contiguous axillary artery; and 8 through a temporary axillary catheter previously placed. The ultrasound-guided patients had fewer punctures than other groups, but the value was not statistically significant. Arterial punctures were infrequent in all techniques. Analyzing all the procedure-related complications, such as hematoma, pneumothorax, brachial-plexus injury, as well as the reasons for catheter removal, no differences were observed among the groups. The functioning time was longer in the ultrasound-guided and previous catheter groups. In 15 years and 8 months of surveillance, no clinical or image evidence for axillary vein stenosis was found. Conclusion The ultrasound guide makes the procedure of inserting catheters in the axillary veins easier, but knowledge of the anatomy of the midaxillary region and the ability to feel the axillary artery pulse (for the palpation method) also allow relatively easy successful implant of catheters in the axillary veins.

Síndrome pulmón riñón en vasculitis sistémica por inmunoglobulina A secundaria a linfoma

David Andrés Ocampo Ramírez; César Augusto Restrepo Valencia

Resumen Paciente de 35 anos de edad, quien debuta con sindrome de pulmon rinon secundario a vasculitis pulmonar y depositos renales granulosos de IgA, en quien se diagnostica vasculitis sistemica por IgA, posteriormente, presenta compromiso pancreatico y cutaneo (Purpura de Henoch - Schonlein), falleciendo ocho meses mas tarde por linfoma difuso de celulas B de alto grado. Este es el reporte de caso numero catorce en el que se establece asociacion entre neoplasia hematologica y Purpura de Henoch - Schonlein.
