Cerebral revascularization using latissimus dorsi muscle free flap transfer--technical note

Area of Science:

• Neurosurgery
• Vascular Surgery
• Microsurgery

Background:

• Moyamoya disease and similar conditions cause progressive stenosis of cerebral arteries, leading to ischemic strokes.
• Cerebral revascularization is crucial for managing extensive ischemic areas involving multiple cerebral artery territories.
• Current revascularization methods may have limitations in reconstructing widespread vascular deficits.

Purpose of the Study:

• To describe and evaluate a novel method of cerebral revascularization using latissimus dorsi muscle free flap transfer.
• To assess the feasibility and efficacy of this technique in patients requiring extensive vascular reconstruction.

Main Methods:

• Harvesting of latissimus dorsi muscle with thoracodorsal vessels.
• Performing microvascular anastomoses between superficial temporal vessels and thoracodorsal vessels in an end-to-end fashion.
• Tailoring the size of the muscle flap to the specific revascularization area.

Main Results:

• Successful revascularization was demonstrated postoperatively via angiography in a patient with moyamoya syndrome.
• Cerebral blood flow studies confirmed improved perfusion reserve capacity.
• The technique, a form of encephalo-myo-synangiosis, proved effective for extensive ischemic regions.

Conclusions:

• Latissimus dorsi muscle free flap transfer is a viable option for cerebral revascularization in moyamoya disease and other extensive ischemic conditions.
• This free muscle flap encephalo-myo-synangiosis technique offers a potential solution for complex vascular reconstruction needs.
• The method shows promise for improving cerebral perfusion in patients with widespread arterial involvement.
