title: [Survival analysis after open vascular surgery and angioplasty in lower limbs vascularization in Rio de Janeiro, Brazil 2006-2013].
abstract: Objective -The aim of this study is survival analysis after lower limb revascularization according to sex, age and procedures.
  
  
  METHODS
  Were analysed in-hospital administrative database coming from the Public Health System of Rio de Janeiro (SUS-RJ) from 2006 through 2010 and the Public Registers of death of Rio de Janeiro (SIM-RJ) from 2006 through 2013. Both groups of information had linkaged using the Stata program of statistics. Three groups of age were studied: 50 years old or less, 50 to 79 and over 70 years old.
  
  
  RESULTS
  More than half of patients received angioplasty as procedures during the study. In both procedures, men were more frequent, except in angioplasty after 70 years of age. In the period of 30 days after discharge in both procedures the survival had an abrupt reduction and it continue reducing until 180 days after open surgery. After these the survival curves run in parallel until the fourth year and then they had the same performance.
  
  
  CONCLUSIONS
  The greatest reduction in survival was registered in the first thirty days after discharge, mainly in women after open surgery. It is necessary to improve in-hospital care in order to improve the survival index on the first thirty days after discharge..
