Summary
Retrograde mesenteric bypass, originating from the iliac arteries, offers symptom-free survival comparable to the standard antegrade approach. This study validates retrograde mesenteric bypass as a viable surgical option for patients.
Area of Science:
- Vascular Surgery
- Abdominal Surgery
Background:
- Antegrade mesenteric artery bypass from the supraceliac aorta is the established method for visceral artery bypass grafts.
- Retrograde bypass, originating from the iliac arteries, is less commonly utilized.
Purpose of the Study:
- To compare the clinical outcomes of antegrade versus retrograde mesenteric artery bypass.
- To evaluate the efficacy and safety of retrograde mesenteric bypass.
Main Methods:
- Retrospective review of 37 patients undergoing 39 mesenteric bypass procedures across two tertiary care centers.
- Assessment of symptom-free survival using chart review, duplex ultrasonography, and telephone interviews.
- Actuarial analysis employing Kaplan-Meier survival estimates.
Main Results:
- Symptom-free survival rates for retrograde mesenteric bypass were found to be similar to those of antegrade bypass.
- No significant difference in outcomes was observed between the two bypass orientations in the studied population.
Conclusions:
- Retrograde mesenteric bypass is a valid and effective alternative for patients requiring visceral artery revascularization.
- The choice of antegrade or retrograde orientation can be surgeon-dependent, with similar efficacy.
