Summary
Unilateral iliac reconstruction for obstructive disease offers excellent long-term outcomes, similar to bilateral procedures. Prophylactic contralateral surgery is often unnecessary, making unilateral reconstruction a valuable option for select patients.
Area of Science:
- Vascular Surgery
- Iliac Artery Disease
Background:
- Controversy exists regarding the optimal surgical approach for unilateral symptomatic iliac obstructive disease.
- Determining the necessity of contralateral intervention following unilateral reconstruction is crucial.
Purpose of the Study:
- To review the outcomes of unilateral iliac reconstruction.
- To assess the need for subsequent contralateral intervention.
- To compare unilateral and bilateral iliac reconstructions.
Main Methods:
- Retrospective analysis of 184 unilateral and 350 aortobilateral reconstructions.
- Treatment allocation based on hemodynamic parameters.
- Comparison of outcomes including symptom relief, hemodynamic improvement, graft patency, morbidity, and mortality.
Main Results:
- Similar symptom relief, hemodynamic improvement, and >80% 10-year primary patency rates for both unilateral and bilateral reconstructions.
- Lower mortality (1.6% vs. 4.9%) and fewer respiratory complications after unilateral reconstruction.
- Only 6% of patients required secondary contralateral reconstruction after initial unilateral surgery.
Conclusions:
- Unilateral iliac reconstruction is a safe and effective procedure for selected patients with iliac obstructive disease.
- It provides excellent long-term outcomes comparable to bilateral reconstruction.
- Prophylactic reconstruction of asymptomatic contralateral iliac stenosis is generally not indicated.
