[Partial gluing in extra-intracranial microvascular anastomoses (author's transl)]

Area of Science:

• Neurosurgery
• Vascular Surgery
• Biomaterials

Context:

• Cerebral revascularization procedures aim to restore blood flow to the brain.
• Microsurgical anastomosis techniques are critical for successful bypass surgery.
• Fibrin glue offers potential benefits in tissue adhesion and hemostasis.

Purpose:

• To develop and evaluate a combined suture-and-glue technique for arterial anastomosis.
• To assess the safety and efficacy of this modified technique in patients undergoing superficial temporal artery to middle cerebral artery bypass.
• To compare the outcomes of this technique with traditional methods.

Summary:

• Experimental studies in rats established a combined suture and human fibrin glue technique for common carotid artery anastomosis.
• This technique was subsequently applied to 12 patients undergoing superficial temporal artery to middle cerebral artery bypass.
• The modified procedure resulted in shorter operation times and fewer complications.

Impact:

• 10 out of 12 patients demonstrated significant improvement in neurological findings post-surgery.
• Five patients regained full working capacity.
• One patient experienced neurological deterioration due to intra-operative hemorrhage, and one patient showed no change.
