Arterial embolectomy in the modern era

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine

Background:

• Arterial embolism poses a significant clinical challenge.
• The Fogarty catheter revolutionized embolic management.

Purpose of the Study:

• To evaluate the efficacy and outcomes of surgical embolectomy for arterial embolism.
• To identify factors influencing embolectomy success and mortality.

Main Methods:

• Retrospective analysis of 148 operative embolectomies for arterial embolism (1966-1980).
• Exclusion of visceral emboli and nonoperative cases.
• Data collection on embolus location, source, anesthesia, and limb salvage.

Main Results:

• 148 embolic episodes in 134 patients; 24 upper extremity, 124 lower extremity.
• Limb salvage rates: 100% for upper extremities, 87% for lower extremities.
• Overall mortality was 20% within 30 days or hospital admission.

Conclusions:

• Embolectomy is effective but success is compromised by delays over 48 hours, advanced patient age, and unknown embolus origins.
• Prompt intervention is crucial for optimal limb salvage in arterial embolism.
