The ability to treat the most difficult and dangerous diseases of the blood vessels of the brain, ie cerebral aneurysms and arteriovenous malformations of the brain without open surgery but with the method of embolization, is one of the most revolutionary developments in the field of neurology. years.
“Instead of open craniotomy and brain surgery, in order for the neurosurgeon to identify and isolate these lesions from the cerebral circulation, we can now treat the vast majority of these diseases intravascularly with embolization,” he said. , Director of the 1st Neurosurgery Clinic – Endovascular Neurosurgery-Embolization Clinic of the Metropolitan General.
With the femoral artery as the gateway and under X-ray guidance with the help of a specialized X-ray machine, a special micro-catheter guided by a special micro-wire (over the wire catheterization) is advanced into the cerebral circulation through the aortic arch and guided into the aortic arch.
Through this microcatheter, detachable platinum microspheres, properly selected and preformed, are guided and released into the aneurysm sac, which they fill and clot, thus isolating the aneurysm from the cerebral circulation and leading to its healing and healing.
In arteriovenous malformations, using a similar technique, the nucleus (nidus) of the malformation is catheterized and a liquid embolic material is injected into it, which solidifies immediately and thus excludes the pathological communication between arteries and veins and thus the existence of arteriovenous.
The evolution of the embolization method has been rapid. Following the publication of the large multicenter study ISAT (International Subarachnoid Aneurysm Trial – Lancet 360, p.1267-1274) in 2002, organized and conducted by the University of Oxford in the United Kingdom and statistically demonstrated the obvious advantages of the method of conventional open surgery, the number of patients with aneurysms treated intravascularly is constantly increasing in all major centers around the world, so that today, the vast majority of brain aneurysms (regenerative or not) are treated intravascularly.
“At the same time, the construction of new innovative devices and the application of new endovascular techniques in recent years, has given further impetus to the treatment of more difficult or complicated and complex aneurysms and vascular malformations in the brain, which until now were considered unoperable.
Vaccination procedures last an average of 2 hours and require hospitalization in the neurosurgery clinic for follow-up and hospitalization for 48 hours. Patients return to work and full activities after 10 days without surgical trauma, postoperative scars or similar problems. “Their ultimate follow-up is done with clinical and imaging examination, usually with magnetic resonance imaging, six months after the operation”, explains Mr. Mitsos.
