Awake surgery with direct electrical stimulation for safe resection of a deep posterior thalamic cavernous malformation - 10/09/25
Highlights |
• | Awake craniotomy with DES enabled safe removal of a deep thalamic cavernoma. |
• | Transparietal approach allowed navigation around critical white matter tracts. |
• | Postoperative MRI confirmed complete resection with tract preservation. |
• | Significant functional recovery observed at 3-month follow-up. |
• | Awake surgery with DES may expand indications for deep-seated CCMs. |
Abstract |
Background |
Treating symptomatic deep-seated cerebral cavernous malformations (CCMs) is challenging due to surgical risks.
Case description |
A 37-year-old man underwent awake craniotomy with direct electrical stimulation (DES) for excision of a left posterior thalamic CCM. A transcortical transventricular approach through the superior parietal lobe enabled safe navigation around critical associative and projection white matter tracts.
Results |
Postoperative MRI confirmed complete resection with preservation of major tracts, and the patient showed significant recovery at three months.
Conclusion |
This case highlights the potential of awake surgery with DES as a safe and effective method for deep-seated CCMs traditionally deemed inoperable.
