Arterial emboli to the arm, often from the heart, require prompt surgical intervention. Early embolectomy significantly improves limb viability, with successful revisions for initial failures.

Area of Science:

  • Vascular Surgery
  • Cardiology
  • Interventional Radiology

Background:

  • Arterial emboli to the arm are a significant cause of limb ischemia.
  • Cardiac sources are the most common etiology, followed by subclavian artery abnormalities.

Purpose of the Study:

  • To review the etiology, management, and outcomes of arterial emboli to the arm.
  • To evaluate the effectiveness of surgical embolectomy and identify factors influencing limb salvage.

Main Methods:

  • Retrospective review of 46 episodes of arterial emboli to the arm in 44 patients.
  • Analysis of lesion location, origin, treatment (surgical vs. non-surgical), and outcomes.

Main Results:

  • Cardiac origin accounted for two-thirds of cases; subclavian artery abnormalities for 14%.

  • Axillary, brachial, and distal-to-elbow lesions occurred in 36%, 52%, and 11% of cases, respectively.
  • Surgical treatment in 36 patients resulted in 33 viable arms; 26 had palpable radial pulses.
  • Six of ten failed first embolectomies were successfully revised; four failures led to limb loss, one due to antithrombin III deficiency.

    • Conclusions:

    • Early surgical exploration is crucial for limb salvage in cases of arterial emboli to the arm.
    • Prompt intervention and successful revision of failed embolectomies significantly improve outcomes.
    • Irreversible ischemic changes necessitate timely management to prevent limb loss.
