Microsurgical Clipping for Brain Aneurysms

What is microsurgical clipping?

Microsurgical clipping is a technique that blocks the blood supply to an aneurysm using a metal clip. This procedure has become the more established method of treating aneurysms. The first aneurysm ever treated by surgical clipping was performed at Johns Hopkins Hospital by Dr Walter Dandy on March 23, 1937.

How is microsurgical clipping performed?

A craniotomy is performed to create an opening in the skull to reach the aneurysm in the brain. The clip is placed on the neck (opening) of the aneurysm to obstruct the flow of blood, and remains inside the brain.

Treating aneurysms at Johns Hopkins

The Johns Hopkins Cerebrovascular Team evaluates each aneurysm patient to decide the best singular therapy or treatment combination for the patient’s specific case.
