Temporary cerebral revascularization using a radial artery in the hand-eyeshade posture: technical note

Area of Science:

• Neurosurgery
• Vascular Surgery
• Surgical Innovation

Background:

• Temporary cerebral revascularization is crucial during complex cerebrovascular surgeries.
• Kamiyama's method using a radial artery graft (RAG) for bypass offers a unique approach.
• The Sugita head frame is commonly used but presents challenges with instrument and hand access during RAG bypass.

Observation:

• The original Kamiyama method, when used with the Sugita frame, has disadvantages.
• These disadvantages include difficulties with instrument and hand manipulation, and restricted use of brain retractors.
• These limitations can impede the efficiency and safety of radial artery to M2 bypass (RA-M2 bypass).

Findings:

• A modified Kamiyama's method is presented to overcome the limitations of the original technique.
• The modification involves elevating the forearm into a 'hand-eyeshade' posture.
• This adjustment aims to improve instrument access, hand stability, and brain retractor usability.

Implications:

• The modified method offers a potential solution for surgeons using the Sugita head frame.
• It may enhance the feasibility and safety of temporary cerebral revascularization via RA-M2 bypass.
• This innovation could lead to improved surgical outcomes in complex cerebrovascular procedures.
