title: Treatment of solitary iliac aneurysms: clinical review of 28 cases.
abstract: OBJECTIVE
  The clinical characteristics and long-term results of patients with solitary iliac aneurysms (SIAs) were investigated.
  
  
  METHODS
  28 consecutive patients who underwent repair of SIAs between 1985 and 2004 were reviewed retrospectively, and compared with those of 536 patients who underwent elective repair of an abdominal aortic aneurysm (AAA) during the same period.
  
  
  RESULTS
  The incidence of SIAs among all aorto-iliac aneurysms was 5.0%. The 28 patients with SIAs were men with a mean age of 69.1 years. There were a collective total of 42 iliac aneurysms in the 28 patients, with 12 patients having multiple aneurysms. Thirty aneurysms involved the common iliac artery, and 12 involved the internal iliac artery. Twenty-two patients had symptoms, although none of the SIAs ruptured. Four patients had coexistent iliac occlusive disease and two patients had femoral occlusive disease. The 5-and 10-year survival rates of the patients with SIAs were 90.5% and 75.4%, whereas those of the patients with AAAs were 76.3% and 54%, respectively (P = 0.089).
  
  
  CONCLUSIONS
  Routine imaging is necessary not only to evaluate the SIAs, but also to detect multiple aneurysms or arterial occlusive disease. Close and long-term followup is mandatory for the early detection of the formation of new aneurysms.
