[Superficialization of autologous vascular access: an alternative to the use of vascular prostheses and permanent catheters].
BACKGROUND
We review our experience with autologous veins Superficialization (Spf), to establish the actual possibilities of this kind of vascular access in our area.


METHODS
Between January/2001 and January/2008, Spf was performed in 48 patients. Mean follow-up time was 18.8 (0.2-75.7) months. Primary failure rate was recorded; primary and secondary survival were estimated using the Kaplan-Meier method; and its possible associations with several variables were analyzed.


RESULTS
the maturity rate was 97.9%; and the rate of primary failure 2.0%. After Spf, mean time of primary and secondary survival were 65 months and 67 months, respectively. Four vascular thromboses were observed. None of the presurgery variables analyzed (age; sex; diabetes mellitus; ipsilateral central catheter; the number of previous VA attempts; and obesity) were significantly associated with maturity rate, primary or secondary survivals.


CONCLUSIONS
the Spf can be a good option alternative to the use of prosthetic grafts or permanent central vascular catheters.
