Open Surgical Management of Atherosclerotic Aortoiliac Occlusive Diseases (AIOD) Type 1

Objective: The common techniques for open anatomical revascularization of aortoiliac occlusive diseases(AIOD) type 1 are aortofemoral bypass (AFB) and aortoiliac endarterectomy (AIE). These procedures are suitable for
hospital where endovascular facility is not available. The aims of this study were to review and compare morbidity,
mortality and 3-year patency rate of AFB and AIE at the Lampang Regional Hospital.
Methods: Patients with AIOD who underwent AFB or AIE for lower extremity ischemia were identified from
prospective medical records during November 2007-November 2013. Demographic and clinical data including
outcome data were obtained from clinical summary records. The decision to perform which operation was based on
surgical risk and surgeon’s preference. Kaplan-Meier analysis was performed to examine the survival of patients.
Results: A total of 10 patients underwent 5 AFB and 5 AIE. The 30-day mortality rate was 10%. One-year survival
rate was 75%. One-year graft patency rate was 100%. Late complication occurred in two patients including worsening
of congestive heart failure and another case with empyema thoracis after treatment HAP. The overall 3-year survival
rate of both AIE and AFB were 40%.
Conclusions: AIE has provided the advantage of avoiding prosthesis. This technique is safe and equally effective
as AFB in term of patency and survival.
