[Hospital Lethality Following Lower Limbs Revascularization in the State of Rio de Janeiro, Brasil, 2006/10].

Introduction: Ischemic peripheral arterial disease is a form of presentation of systemic atherosclerosis and can be treated by angioplasty or open vascular surgery Objective: To find in-hospital lethality after revascularization according to sex, age, procedures and hospitalization conditions.

Method: The data comes from authorizations to hospitalize from The State of Rio De Janeiro´s Public Healthcare System from the years 2006/10. We performed a search using the International Code of Diseases tenth revision (ICD-10) to identify codes of revascularization by angioplasty or open vascular surgery. The statistical analysis was done with Stata Program of statistics.

Results: The procedures were performed in 41 hospitals, public, private and university medical facilities. We identified 1558 registrations, 900 (57.8%) men and 658 women (42.2%). There were 68 hospital deaths and in-hospital mortality was 3.7% for men and 5.1% for women.The lethality was 2.6% under 50 years old, 4.1% between 50-69 years and 5.3% above 70 years. We identified 846 (46.6%) open surgeries and 968 (53.4%) angioplasties with a lethality of 2.0% in angioplasties (16/809) and 7.0% (52/748) with open surgeries. Elective procedures had 4.6 % of lethality and 4.1% in urgent/emergency procedures. Elective angioplasties had a mortality of 2.6%, and 1.4% in urgent/emergency. Open surgeries had the mortality of 6.5% and 7.5%, respectively.

Conclusion: Hospital lethality showed high levels in open vascular surgery and angioplasties. A very sensitive aspect is the mortality of angioplasties in elective patients. These results are similar to those observed in myocardial revascularization from atherosclerosis. Public hospitals had lower lethality.
