Insights
Surgical revascularization effectively treated a patient with complex carotid and subclavian artery occlusions causing upper limb ischemia and dizziness. The combined carotid endarterectomy and bypass restored limb perfusion and resolved symptoms.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Neurology
Background:
- Subclavian artery occlusion causes upper limb ischemia and vertebrobasilar insufficiency.
- Concurrent carotid artery occlusion complicates management, demanding complex surgical solutions.
- Surgical revascularization is a viable option for select patients with these conditions.
Purpose of the Study:
- To present a case of complex supra-aortic occlusive disease involving both subclavian and carotid arteries.
- To highlight the successful surgical management of chronic ischemia in such a case.
- To demonstrate the efficacy of a combined surgical approach.
Main Methods:
- A female patient in her 60s with giddiness and left upper limb pain was evaluated.
- Doppler ultrasound and CT angiography revealed left subclavian artery occlusion and left common/internal carotid artery occlusion.
- The patient underwent left common carotid endarterectomy with carotid-to-subclavian bypass via a supraclavicular approach.
Main Results:
- Post-operatively, pulses in the left upper limb were restored.
- The patient experienced complete resolution of giddiness.
- Follow-up Doppler imaging confirmed good arterial flow in the upper limb.
Conclusions:
- Combined carotid endarterectomy and carotid-to-subclavian bypass is an effective treatment for complex supra-aortic occlusive disease.
- This surgical strategy successfully restored limb perfusion and resolved ischemic symptoms.
- Surgical revascularization offers a valuable therapeutic option for selected patients with combined carotid and subclavian artery occlusions.
Abstract:
Occlusion of the subclavian artery is an important cause of upper limb ischaemia and vertebrobasilar insufficiency. When associated with carotid artery occlusion, management becomes complex and technically demanding. Surgical revascularisation remains an effective option in selected patients. We report a female in her 60s who presented with giddiness and left upper limb pain, with clinical evidence of chronic ischaemia. Doppler ultrasound revealed monophasic flow in the left axillary artery, CT angiography showed a short-segment chronic total occlusion of the left subclavian artery at its origin along with complete occlusion of the left common and internal carotid arteries. The patient underwent left common carotid endarterectomy with carotid-to-subclavian bypass via supraclavicular approach. There was restoration of pulses in the left upper limb and complete resolution of giddiness. Follow-up Doppler imaging confirmed good flow in the upper limb arteries, demonstrating the effectiveness of this combined surgical approach in complex supra-aortic occlusive disease.
