Surgical reconstruction of the proximal subclavian and vertebral arteries
Insights
Surgical intervention for vertebral artery hypoperfusion, caused by stenotic lesions, offers excellent symptom relief. A direct anastomosis procedure demonstrated a low complication rate and successful restoration of arterial circulation.
Area of Science:
- Vascular Surgery
- Cerebrovascular Medicine
- Interventional Cardiology
Background:
- Atherosclerotic lesions in the extracranial internal carotid artery are well-managed.
- Stenotic lesions at the origin of vertebral or subclavian arteries can cause basilar artery hypoperfusion and cerebellar symptoms.
- Surgical correction is a viable option for symptom relief.
Purpose of the Study:
- To evaluate the efficacy and safety of a direct arterial anastomosis procedure for treating vertebral hypoperfusion.
- To report outcomes of a specific surgical technique over a decade.
Main Methods:
- A direct anastomosis was performed from the vertebral or subclavian artery distal to the lesion to the adjacent common carotid artery.
- The procedure was performed 579 times over a ten-year period.
Main Results:
- The study reported one death and no instances of neurologic deficit in 579 procedures.
- Complications included one lymph fistula requiring closure and three reoperations for bleeding.
- Overall results were deemed excellent, with successful restoration of arterial circulation.
Conclusions:
- Direct arterial anastomosis is an effective and safe surgical option for patients experiencing cerebellar symptoms due to vertebral hypoperfusion.
- This technique provides a reliable method for restoring arterial circulation in the affected population.
Abstract:
The diagnosis and management of atherosclerotic lesions of the extracranial internal carotid artery has become fairly well established. Symptoms of basilar artery hypoperfusion may be due to stenotic lesions at the origin of either or both vertebral arteries or the proximal subclavian artery. Surgical correction can offer relief of symptoms. For the past decade, we have used a direct anastomosis from the vertebral or subclavian artery distal to the lesion to the adjacent common carotid artery. We have done this procedure 579 times, with one death and no neurologic deficit. A lymph fistula required closure in one patient, and reoperation was necessary in three patients because of bleeding. The results have been excellent, and we continue to offer this method of restoring arterial circulation in patients with cerebellar symptoms and vertebral hypoperfusion.
