Iliac artery aneurysms are rare and difficult to diagnose, with a high mortality rate. Early surgical intervention and arterial reconstruction are recommended for better survival outcomes.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Clinical Outcomes

Background:

  • Iliac artery aneurysms (IAAs) are uncommon vascular conditions.
  • Diagnosis can be challenging, leading to delayed treatment.
  • IAAs carry a higher mortality risk compared to aortic aneurysms.

Purpose of the Study:

  • To analyze clinical and diagnostic data of patients with IAAs.
  • To evaluate surgical treatment outcomes for IAAs.
  • To emphasize the importance of early diagnosis and intervention.

Main Methods:

  • Retrospective analysis of 22 male patients with IAAs undergoing surgery over 22 years.
  • Review of clinical presentation, diagnostic findings, and surgical procedures.
  • Long-term follow-up of surviving patients.

Main Results:

  • 30 isolated IAAs identified, predominantly in the common iliac artery (86.6%) and on the right side (66.6%).
  • Symptomatic presentation in 68.2% of patients; rupture occurred in 22.7%, including some initially asymptomatic cases.
  • Elective surgery yielded a significantly higher survival rate (17/17) compared to emergency surgery post-rupture (3/20).

Conclusions:

  • Iliac artery aneurysms require prompt diagnosis and surgical management.
  • Elective resection and arterial reconstruction are crucial for improving patient survival.
  • Delayed diagnosis and rupture are associated with increased mortality.
