How to perform interventional surgery for cerebral vascular aneurysm

How is interventional surgery for cerebral vascular aneurysm performed?

1. First, let's get to know the necessary artifact for interventional surgery - the spring coil. This is a platinum-made metal wire with a soft texture. It has different diameters, lengths, shapes and other specifications, and is suitable for cerebral aneurysms of different shapes and sizes. The spring coil is connected to a metal push rod that is more than one meter long.

2. The process of interventional surgery is ultimately a process of catheter operation. The conventional approach is as follows: a thick catheter - a guide catheter - is inserted through a puncture in one side of the femoral artery, and the guide catheter is sent through the abdominal aorta and thoracic aorta into the cerebral artery with a long aneurysm. Then a thin catheter with a microcatheter tip that is not much thicker than a sewing thread is sent into the tumor-bearing artery through this thick catheter, and the tip of the microcatheter is carefully sent into the aneurysm cavity under the guidance of the micro guidewire. The delivery and packing of the spring coil mentioned above are completed through this microcatheter.

Sequelae of interventional surgery for cerebral vascular aneurysms:

1. Brain aneurysms are caused by local expansion of blood vessels, so in life, they are basically treated by surgery. There is no other treatment method. Generally, there are interventional embolization and clipping operations. Generally speaking, if the operation is well performed and the condition is easy to treat, there will be no sequelae.

2. Posterior communicating artery aneurysms are basically no problem after surgery, but anterior communicating artery aneurysms are more difficult to treat and may cause some complications after surgery, including hemiplegia and coma, and even death in more serious cases. Of course, these are closely related to the technical level of the operator.

3. Surgical treatment of aneurysms is a traditional treatment method, especially for the anterior circulation, which can be clipped surgically. Although it has a relatively high risk, if the aneurysm ruptures during surgery, it can be temporarily clipped to control bleeding. The main complications of surgical treatment of aneurysms include hemiplegia and coma, and in severe cases, death.
