A Systematic Review and Meta-Analysis of Reported Success and Complication Outcomes the Management of Acute Upper Limb Ischemia.

In 30 seconds

This systematic review and random-effects meta-analysis examined outcomes of medical, open surgical, and endovascular management for acute upper limb ischemia. It included 27 observational studies involving 3,162 patients; no randomized trials were identified. Reported overall success was 90.1% (95% confidence interval [CI]: 84.5-94.7%) with surgery, 71.8% (95% CI: 41.1-94.9%) with endovascular management, and 79.4% (95% CI: 52.6-97.8%) with medical management. However, substantial heterogeneity, high risk of bias across all studies, and low to very low certainty mean these estimates cannot establish which strategy is more effective.

Key findings

• Reported success rates were 90.1% (95% CI: 84.5-94.7%) for surgery, 71.8% (95% CI: 41.1-94.9%) for endovascular management, and 79.4% (95% CI: 52.6-97.8%) for medical management.
• Substantial heterogeneity was present across all treatment groups (I 2 >87%), and complication and reintervention rates varied widely.
• All 27 studies were judged at high risk of bias; certainty of evidence was low to very low.

Why it matters

Acute upper limb ischemia is a time-sensitive condition, but the available evidence does not reliably distinguish outcomes among medical, surgical, and endovascular approaches. The pooled success estimates describe reported experience rather than comparative treatment effects. Recognizing this uncertainty is important when interpreting apparent differences and highlights the need for better comparative evidence and standardized outcome reporting.

What to keep in mind

Evidence came entirely from observational studies, with no randomized trials. Studies were heterogeneous, at high risk of bias, and often lacked adjustment for confounding and complete baseline severity reporting; long-term functional follow-up and standardized outcome definitions were lacking.
