Summary
A new femoral-carotid extraluminal shunt allows carotid endarterectomy without interrupting brain blood flow. This innovative shunt is simple, safe, and effective in preventing cerebral ischemic events during surgery.
Area of Science:
- Vascular Surgery
- Cerebrovascular Surgery
- Neurosurgery
Background:
- Carotid endarterectomy reduces cerebral ischemic events in patients with internal carotid artery stenosis.
- Intraluminal shunts are used when collateral circulation is insufficient but present technical challenges.
- Existing shunts have issues with positioning, variable flow, and surgical interruption.
Purpose of the Study:
- To introduce a novel temporary extraluminal shunt for carotid endarterectomy.
- To enable carotid endarterectomy without interrupting cerebral blood flow.
- To overcome the limitations of traditional intraluminal shunts.
Main Methods:
- A new femoral-carotid extraluminal shunt with an integrated roller pump was developed.
- The shunt was used in 35 patients with insufficient collateral circulation during carotid endarterectomy.
- Electroencephalographic monitoring assessed cerebral circulation during the procedure.
Main Results:
- The extraluminal shunt successfully normalized electroencephalographic monitoring in all cases.
- The shunt was simple and easy to position and use.
- No postoperative complications occurred, except for one stroke post-surgery.
Conclusions:
- The novel femoral-carotid extraluminal shunt is effective and safe for carotid endarterectomy.
- This method maintains cerebral blood flow, simplifying the procedure.
- Further studies are needed to confirm these promising results.
