The neurosurgery is a complex vascular subspecialty that is related to bleeding or stroke in the brain or spinal cord injuries.
Vascular neurosurgery is the part dealing neurosurgery those injuries that have caused or may cause bleeding or stroke in the brain or spinal cord.
It is a very complex subspecialty due to the high technical requirements precisely, their relatively low frequency and consequences of these injuries can have on the life and function of the patient.
It is generally responsible for arterial aneurysms, vascular malformations and dural arteriovenous fistulas. Cavernomas also treats that are halfway between vascular lesions and tumors, and some diseases that can cause strokes, like Moya-Moya disease.
Briefly summarizing its scope, we see each of these injuries:
• Regarding cerebral aneurysms: are secondary arterial dilation weakening of the vessel wall appearing in bifurcations of cerebral arteries. They can be diagnosed by chance in the course of a study for another reason or be symptomatic. When they are symptomatic they should be treated, either by microsurgery or endovascular treatment. The aim pursued is to exclude the aneurysm from circulation completely. Regarding asymptomatic, it is assumed to be treated because of the risk of rupture, those who have demonstrated growth or irregular. It is imperative that it be evaluated by a neurosurgeon with extensive experience.
• Regarding AVMs most are diagnosed after bleeding. In these cases it is essential that the patient go to a center or neurosurgeon experienced as brain surgery and spinal malformations is probably the most complicated among the operations in neurosurgery. Depending on how the malformation, its location and size, and age of the patient should choose the best treatment.
• In connection with dural arteriovenous fistulas depending on the location (cranial / spinal) can perform a surgical or endovascular treatment. Spinal often best resolved by surgery.
• Referring to the cavernous, of having to be treated, the treatment of choice is surgery, although in each case there is the need to individualize treatment.
