Extracranial-Intracranial Microsurgical Bypass Using a Y-Shaped Vein Graft From the Hand

Area of Science:

• Neurosurgery
• Plastic Surgery
• Vascular Surgery

Background:

• Extracranial-intracranial (EC-IC) bypass is typically performed by neurosurgeons.
• Collaboration with plastic surgeons offers unique advantages due to their microvascular expertise.

Purpose of the Study:

• To outline a Canadian perspective on the collaborative approach between neurosurgeons and plastic surgeons for EC-IC bypass.
• To present a novel case report on using a dorsal hand vein graft for EC-IC bypass.

Main Methods:

• Retrospective review of collaborative EC-IC bypass cases.
• Description of the combined surgical technique involving neurosurgeons and plastic surgeons.
• Detailed case report of a patient undergoing EC-IC bypass with a Y-shaped dorsal hand vein graft.

Main Results:

• The collaborative approach effectively utilizes plastic surgeons' skills in donor vessel dissection and bypass.
• A novel Y-shaped dorsal hand vein graft was successfully employed for EC-IC bypass.
• This approach expands the options for vascular reconstruction in EC-IC bypass surgery.

Conclusions:

• The combined expertise of neurosurgeons and plastic surgeons enhances EC-IC bypass procedures.
• The use of a dorsal hand Y-shaped vein graft represents a new option for EC-IC bypass reconstruction.
• This collaborative model is beneficial for complex cerebrovascular cases.
