Chronic upper extremity ischemia: current concepts in management
Insights
Symptomatic innominate or subclavian artery obstructions often cause neurologic and extremity issues. Surgical repair or balloon angioplasty can reverse these symptoms, with sympathectomy offering a solution when perfusion restoration is incomplete.
Area of Science:
- Vascular Surgery
- Neurology
- Interventional Cardiology
Background:
- Innominate and subclavian artery obstructions can lead to significant neurologic and extremity symptoms.
- These conditions are often associated with concomitant carotid disease, increasing stroke risk.
Purpose of the Study:
- To review the management of symptomatic innominate or subclavian artery obstructions.
- To highlight the effectiveness of various surgical and interventional approaches.
Main Methods:
- Review of extrathoracic surgical approaches for innominate/subclavian obstructions.
- Evaluation of balloon angioplasty utility.
- Assessment of carotid disease management's impact on subclavian steal symptoms.
- Analysis of reconstruction outcomes for lesions distal to the vertebral artery.
- Consideration of sympathectomy's role.
Main Results:
- Extrathoracic surgical approaches effectively reverse neurologic and extremity symptoms.
- Balloon angioplasty shows emerging utility for these obstructions.
- Correction of concomitant carotid disease can prevent stroke and mitigate subclavian steal symptoms.
- Reconstruction of lesions distal to the vertebral artery yields dramatic and durable improvement.
- Sympathectomy is valuable when complete perfusion restoration is not achievable.
Conclusions:
- Symptomatic innominate and subclavian artery obstructions are treatable with various methods.
- Surgical and interventional strategies offer effective symptom reversal and stroke prevention.
- Sympathectomy provides a therapeutic option for complex cases.
Abstract:
As a rule, the few innominate or subclavian obstructions that are symptomatic produce neurologic and extremity symptoms that are easily reversed by an extrathoracic surgical approach. Balloon angioplasty is seeing some utility for this problem also. Concomitant carotid disease may be more significant in that its correction may not only prevent stroke but also mitigate symptoms of subclavian steal. The reconstruction of lesions distal to the vertebral artery frequently results in dramatic and durable improvement. Sympathectomy has a valuable role to play in those cases in which restoration of perfusion cannot be complete.
