title: [Influence of gender on development and prognosis of atherosclerosis obliterans].
abstract: OBJECTIVE
  To evaluate the influence of gender on the development and prognosis of atherosclerosis obliterans (ASO).
  
  
  METHODS
  Eight hundred and forty-two patients with ASO were treated from January 2000 to February 2007. The clinical data were retrospectively collected. And the influence of gender on the development and prognosis of ASO was investigated.
  
  
  RESULTS
  Among the 842 patients, 661 were male and 181 were female. The ratio of male to female was 3.65 : 1.00, and the ratio decreased with increasing age. The mean age of male and female patients were (71.7 +/- 9.0) years and (75.7 +/- 6.8) years, respectively. Significantly more iliac lesions occurred in male patients than in female, while female patients experienced more infrainguinal lesions. The coexistence rate of diabetes and amputation rate were significantly higher in female patients than in male (46.4%/24.7% and 16.0%/9.1%, respectively).
  
  
  CONCLUSIONS
  The female patients with ASO appear to have poorer prognosis than the male, despite their lower incidence of ASO.
