Summary
Selective cerebral perfusion via arch vessel cannulation during thoracic aorta surgery significantly reduced stroke risk. This technique, using epiaortic echography to select optimal cannulation sites, proved safe and effective in preventing brain injury.
Area of Science:
- Cardiovascular Surgery
- Neurosurgery
- Vascular Surgery
Background:
- Brain injury is a significant complication of thoracic aorta surgery.
- Advances in surgical techniques and anesthesia have not eliminated this risk.
Purpose of the Study:
- To evaluate the safety and efficacy of arch vessel cannulation for selective cerebral perfusion.
- To assess the impact of this technique on perioperative stroke rates during total arch replacement.
Main Methods:
- Retrospective analysis of 32 patients undergoing total arch replacement between 1998 and 2000.
- Arch vessel cannulation for selective cerebral perfusion.
- Intraoperative epiaortic echography to identify optimal cannulation sites on brachiocephalic and left carotid arteries.
Main Results:
- No in-hospital deaths occurred in the study cohort.
- Only one patient (3.1%) experienced a perioperative stroke.
- Successful implementation of selective cerebral perfusion was achieved.
Conclusions:
- Arch vessel cannulation for selective cerebral perfusion is a safe and effective method.
- Intraoperative epiaortic echography is crucial for identifying suitable cannulation sites.
- This technique helps prevent perioperative cerebral embolism during thoracic aorta repair.
