Summary
Routine intraoperative angiography after upper-limb arterial embolectomy significantly reduces reocclusion rates. This procedure helps ensure complete removal of blockages, improving patient outcomes and preventing future clots.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Acute Limb Ischemia
Background:
- Fogarty balloon catheter thromboembolectomy is the standard for acute limb ischemia.
- Intraoperative arteriography aids in assessing procedure completeness.
- Debate exists on routine vs. selective use of angiography.
Purpose of the Study:
- To evaluate the value of routine completion angiography in upper-limb acute arterial embolism.
- To compare outcomes between selective and routine angiography use.
- To identify factors influencing reocclusion and mortality.
Main Methods:
- Retrospective analysis of 100 patients over 18 years.
- Comparison of two groups: selective (A) vs. routine (B) angiography.
- Investigation of factors associated with reocclusion and mortality.
Main Results:
- Routine angiography (Group B) led to more frequent procedure extensions (26% vs. 4%).
- Group B showed significantly lower reocclusion rates at 24 months (2% vs. 12%).
- Diabetes Mellitus was a significant predictor of 2-year mortality.
Conclusions:
- Routine intraoperative angiography improves outcomes after upper-limb embolectomy.
- It increases procedure extension rates but lowers reocclusion risk.
- Completion angiography is crucial for preventing reocclusion, with a hazard ratio of 5.44.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
