[Catheter in the superior vena cava for hemodialysis as a last resort in superior hemithorax]. / Catéter en vena cava superior para hemodiálisis entre los últimos recursos en hemitórax superior.

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.

[Implanting haemodialysis catheters in the brachiocephalic vein: a little-used approach]. / Implantación de catéteres para hemodiálisis en vena innominada, una ruta poco utilizada.

We report three patients with chronic renal failure in hemodialysis therapy, which had exhausted conventional venous access in the upper hemitórax (internal jugular, subclavian, axillary) for hemodialysis, primarily due to thrombosis of these veins by previous catheterization. We chose the technique of Rao et al. and cols for puncture of innominate vein, resulting in the implantation of catheters and their subsequent subcutaneous tunneling. Permanent catheters3 work properly and are permeable to the date after a period averaging 8 months.

Catéter en vena cava superior para hemodiálisis entre los últimos recursos en hemitórax superior / Catheter in the superior vena cava for hemodialysis as a last resort in superior hemithorax

Se presentan 4 pacientes con enfermedad renal crónica en terapia hemodialítica en quienes se habían agotado los accesos venosos clásicos (yugular interno, subclavio)y no clásicos (axilar e innominado) en el hemitórax superior para hemodiálisis, debido principalmente a trombosis de los mismos por cateterismos anteriores, y que no eran candidatos a diálisis peritoneal. En ellos, con la técnica recomendada por Archundia et al., se implantaron4 catéteres permanentes directamente en la vena cava superior, con posterior tunelización subcutánea. Los catéteres funcionaron adecuadamente y están permeables actualmente después de un período de utilización promedio de 19 meses (AU)

Placement of vascular access catheters for haemodialysis in the innominate vein: a little-used approach

We report three patients with chronic renal failure in hemodialysis therapy, which had exhausted conventional venous access in the upper hemitórax(internal jugular, subclavian, axillary) for hemodialysis, primarily due to thrombosis of these veins by previous catheterization. We chose the technique of Raoandcols for puncture of in nominate vein, resulting in the implantation of catheter s and their subsequent subcutaneous tunneling. Permanent catheters3 work properly and are permeable to the date after a period averaging 8 months (AU)

En ellos se optó, mediante la técnica de Raoetal., por puncionar la vena innominada, lográndose la implantación posterior de catéteres y su tunelización subcutánea. Los catéteres permanentes3funcionaron adecuadamente y están permeables a la fecha después de un periodo promedio de ocho meses (AU)
