Axillobifemoral bypass: elective versus emergent operation

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Surgical Outcomes Research

Background:

• Axillobifemoral bypass (AxBFB) is often viewed as a suboptimal procedure due to historically poor long-term results.
• The impact of surgical timing (elective vs. emergency) on AxBFB outcomes has not been thoroughly investigated.
• Patient selection and urgency may significantly influence the perceived success rates of AxBFB.

Purpose of the Study:

• To evaluate whether the elective or emergency nature of axillobifemoral bypass impacts its long-term results.
• To compare primary patency, limb salvage, and survival rates between elective and emergency AxBFB cohorts.
• To identify key factors influencing the disparate clinical outcomes reported for AxBFB procedures.

Main Methods:

• Retrospective analysis of 59 axillobifemoral bypass (AxBFB) procedures performed over a 10-year period.
• Patients were divided into two groups: Group A (41 patients, elective AxBFB) and Group B (18 patients, emergency AxBFB).
• Comparison of primary patency, limb salvage, and survival rates between the two groups.

Main Results:

• Elective AxBFB (Group A) demonstrated significantly better primary patency (p < 0.002), limb salvage (p < 0.002), and survival (p < 0.03) compared to emergency AxBFB (Group B).
• Indications for elective surgery included limb-threatening ischemia, infected aortic grafts, and severe claudication.
• Indications for emergency surgery included acute limb ischemia and aortoduodenal fistula.

Conclusions:

• Axillobifemoral bypass performed electively offers satisfactory palliation for severe vascular disease in high-risk patients.
• The timing of the operation (elective vs. emergency) is a crucial predictor of clinical outcomes for AxBFB.
• Understanding the indications and urgency is essential for interpreting the varied results of AxBFB reported in the literature.
