Iliac artery aneurysms and dissections (ADIAs) are more common in men. Endovascular repair significantly reduces hospital mortality compared to open surgery for ADIAs, with comparable outcomes between sexes.
Area of Science:
- Vascular Surgery
- Epidemiology
- Public Health
Background:
- Aneurysms and dissections of the iliac artery (ADIAs) are significant vascular conditions.
- Isolated iliac artery pathologies are rarely reported, despite their clinical importance.
- Understanding the epidemiology and treatment outcomes of ADIA is crucial for vascular health management.
Purpose of the Study:
- To investigate the epidemiology of ADIA in Switzerland.
- To determine the incidence of ADIA treatment.
- To analyze hospital outcomes, including mortality rates, for ADIA.
Main Methods:
- Retrospective analysis of diagnosis-related group (DRG) statistics in Switzerland from 2011 to 2018.
- Inclusion of ADIA cases, excluding those with concomitant aortic pathology treatment.
- Assessment of age-standardized incidence rates, treatment outcomes, and multivariable logistic regression for mortality factors.
Main Results:
- 1037 ADIA cases were hospitalized between 2011 and 2018.
- Elective ADIA treatment incidence was significantly higher in men (increasing from 1.5 to 2.4 per 100,000) than women (stable at ~0.2 per 100,000).
- Endovascular repair demonstrated significantly lower hospital mortality rates (0.8% elective, 6.7% emergency) compared to open repair (3.1% elective, 18.4% emergency).
Conclusions:
- Nationwide data reveal ADIA treatment incidence is substantially higher in men than women.
- Endovascular repair is associated with significantly reduced hospital mortality for ADIA compared to open repair.
- Hospital mortality rates for ADIA were comparable between men and women.
