Aortic grafting procedures: tailoring the options
Insights
This study on aortoiliac and aortofemoral bypass grafts found a high five-year patency rate of 88%. Additional procedures significantly increased complications and blood transfusions, suggesting careful surgical decision-making.
Area of Science:
- Vascular Surgery
- Graft Patency
Background:
- Aortoiliac and aortofemoral bypass grafts are crucial for treating peripheral artery disease.
- Assessing factors influencing graft patency and patient outcomes is essential for optimizing surgical strategies.
Purpose of the Study:
- To evaluate the five-year patency rates of aortoiliac or aortofemoral bypass grafts.
- To compare outcomes based on graft laterality, inclusion of sympathectomy, and graft type (aortofemoral vs. aortoiliac).
- To determine the impact of additional procedures on complications and blood transfusion requirements.
Main Methods:
- Retrospective review of medical records from 165 patients undergoing aortoiliac or aortofemoral bypass grafting.
- Analysis of overall five-year patency rates.
- Comparison of outcomes between different surgical approaches and the necessity of concomitant procedures.
Main Results:
- The overall five-year patency rate for bypass grafts was 88%.
- No significant differences in operative duration, blood transfused, complications, or patency rates were observed between unilateral and bilateral grafts, with or without sympathectomy, or between aortofemoral and aortoiliac grafts.
- Performing additional procedures alongside bypass grafting led to a significant increase in blood transfused and postoperative complications.
Conclusions:
- Surgical intervention for aortoiliac or aortofemoral bypass should be guided by patient symptoms.
- Anatomical considerations should dictate the choice of anastomosis site.
- Concomitant procedures should be limited to those with clear therapeutic benefits and essential for ensuring graft patency.
Abstract:
Records from 165 patients who had received aortoiliac or aortofemoral bypass grafts were reviewed. The overall five-year patency rate was 88%. There was no significant difference in operative duration, amount of blood transfused, postoperative complications, and life table patency rates when comparisons were made of unilateral and bilateral grafts, of patients who underwent sympathectomy and those who did not, or of aortofemoral and aortoiliac grafts. When bypass grafting included an additional procedure, the amount of blood transfused and the number of postoperative complications increased significantly. We conclude that (1) the decision to operate should be based on symptoms, (2) the site of anastomosis should be chosen from anatomic characteristics, and (3) other procedures should not be performed except to achieve obvious therapeutic goals and to assure graft patency.
