Intracranial microvascular anastomoses are surgical techniques used to connect two blood vessels in the brain. These anastomoses are often performed to restore blood flow to a part of the brain that has been damaged by a stroke or injury. Microvascular anastomoses are complex procedures that require a high level of skill and experience. However, they can be life-saving for patients who have suffered a stroke or brain injury.

Basic Techniques

There are three basic techniques for performing intracranial microvascular anastomoses:

End-to-end anastomosis: This technique is used to connect two blood vessels that are of the same size. The ends of the blood vessels are trimmed and then sutured together.
End-to-side anastomosis: This technique is used to connect a smaller blood vessel to a larger blood vessel. The end of the smaller blood vessel is trimmed and then sutured to the side of the larger blood vessel.
Side-to-side anastomosis: This technique is used to connect two blood vessels that are of different sizes. The sides of the blood vessels are trimmed and then sutured together.

The choice of which technique to use depends on the size and location of the blood vessels that are being connected.

Surgical Applications

Intracranial microvascular anastomoses are used in a variety of surgical applications, including:

Revascularization of ischemic brain tissue: This is the most common use of intracranial microvascular anastomoses. Ischemic brain tissue is tissue that has been deprived of blood flow. Microvascular anastomoses can be used to restore blood flow to ischemic brain tissue and prevent дальнейшее повреждение.
Treatment of brain aneurysms: A brain aneurysm is a weakened area in the wall of a blood vessel in the brain. Microvascular anastomoses can be used to bypass an aneurysm and prevent it from bursting.
Treatment of arteriovenous malformations: An arteriovenous malformation is an abnormal connection between an artery and a vein. Microvascular anastomoses can be used to redirect blood flow away from an arteriovenous malformation and prevent it from causing damage to the brain.

Intracranial microvascular anastomoses are complex surgical procedures that require a high level of skill and experience. However, they can be life-saving for patients who have suffered a stroke or brain injury. The basic techniques and surgical applications of intracranial microvascular anastomoses are described in this article.
