DEFINITION: Clustering between arteries and veins during the development of cerebral vessels, after incomplete development of the vessel wall, is called cerebral arterio-venous malformation (AVM).
AVM General characteristics and Incidence
It is the most common cause of childhood cerebral hemorrhages,
5-10% of adult cerebral hemorrhages,
1/10 of brain aneurysms (ballooning)
While cerebral hemorrhage usually occurs until the age of 40, the bleeding rate decreases over the age of 55,
While 90% of AVMs are seen in the brain, 10% are seen in the cerebellum,
Annual cerebral hemorrhage rate is 4% kind.
AVM Clinical Complaints and Findings
A patient with AVM can apply to both emergency and polyclinics with the above-listed main topics, for example, late epilepsy, or with clinical findings of an emergency small or large brain hemorrhage. Rarely, after occult or prominent cerebral hemorrhage, they may present with complaints of water accumulation in the brain (hydrocephalus) (gait disturbance, urinary incontinence, and memory loss) due to obstruction of cerebrospinal water circulation. In childhood, they apply to pediatric polyclinics urgently or electively with congenital heart failure complaints. As a result, a patient with AVM manifests itself in 4 main clinical titles;
1: Brain hemorrhage,
2: Convulsion (epilepsy),
3: Water collection in the brain (hydrocephalus),
4: They apply to neurological emergency or polyclinics with heart failure in infants.
AVM Diagnosis
The following examination methods are used in the diagnosis of AVM with a cerebrovascular disease: Today, the following examination methods, which are advanced neuro-imaging methods, are used in combination or separately in the diagnosis of AVM. These;
1: Computed Tomography (CT),
2: Computed Tomography Angiography (CTA),
3: MR Angiography (MRA),
4: Digital Cerebral Angiography (DSA).
AVM Treatment
AVM treatment is a very complex and difficult subject, and the treatment options listed below are evaluated individually or in combination for each patient. There are advantages and disadvantages, and it is necessary to evaluate the indications and complications individually. Conclusion: The best treatment method in a benign vascular cluster is the treatment that preserves the comfort of the patient, completely eliminates the lesion if possible, and most importantly, does not leave any neurological sequelae.
1: Surgical treatment,
2: Gamma knife,
3: Embolization,
4: Combination of these 3 treatment options
5: Follow-up.
