Gender differences in patients treated for critical limb ischemia

Area of Science:

• Vascular Surgery
• Ischemia Research
• Gender Medicine

Background:

• Critical limb ischemia (CLI) affects both men and women, but gender-based differences in presentation and outcomes are not fully understood.
• Understanding these differences is crucial for optimizing treatment strategies and improving patient care.

Purpose of the Study:

• To compare pre-operative conditions, lesion localization, and treatment outcomes in men and women undergoing vascular reconstruction or percutaneous transluminal angioplasty (PTA) for CLI.
• To identify potential gender-specific factors influencing CLI management.

Main Methods:

• Retrospective cohort study analyzing medical records of 119 women and 115 men treated for CLI between 1993-1994.
• Data included pre-operative characteristics, lesion location, secondary interventions, amputations, and mortality up to 2003.

Main Results:

• Women were older (mean 74 vs 69 years), had lower rates of diabetes (22% vs 43%), and less smoking history (63% vs 82%) compared to men.
• Suprainguinal interventions were more common in women (44% vs 19%).
• Amputation and survival rates were similar between genders, even after adjusting for age and diabetes.

Conclusions:

• Despite demographic and risk factor differences, gender did not significantly impact critical limb ischemia treatment outcomes.
• Biological, anatomical, and potential selection process differences may contribute to observed gender variations in CLI presentation.
