Reintervention and mortality after infrainguinal reconstructive surgery for leg ischaemia

Area of Science:

• Vascular Surgery
• Graft Patency
• Limb Salvage Procedures

Background:

• Atherosclerosis progression and graft complications necessitate late vascular interventions.
• Infrainguinal bypass grafting is a critical procedure for limb salvage.
• Understanding long-term outcomes is essential for patient management.

Purpose of the Study:

• To determine the cumulative risk of late reintervention or death following infrainguinal bypass grafting.
• To identify risk factors associated with adverse outcomes after bypass surgery.
• To provide data relevant for informed consent in high-risk patient groups.

Main Methods:

• Prospective data collection from 205 consecutive patients with limb-threatening ischemia.
• Life-table and multivariate analyses were used for risk estimation.
• Mean follow-up duration was 3.3 years.

Main Results:

• 33% of patients required 112 vascular interventions beyond 30 days post-bypass.
• Cumulative reintervention rates reached 25% at 1 year and 40% at 5 years.
• Poor run-off and prosthetic grafts were significant risk factors; diabetes and renal insufficiency impacted survival.

Conclusions:

• Late reinterventions are frequent after infrainguinal bypass for limb-threatening ischemia.
• These interventions contribute to patient morbidity and discomfort.
• Risk stratification and clear communication are vital, especially for high-risk individuals.
