Aims and objectives
To describe the epidemiology and characteristics of the intracranial arteriovenous malformations and their clinical evolution over the years of the patients treated with embolization in our hospital. 2.
To describe the principals techniques and materials used to embolize the intracranial arteriovenous malformations,
talking about arterial access and vascular closure devices.
Methods and materials
We selected all patients with embolized arteriovenous malformatios (AVMs) in our hospital. Patients with only fistulas were excluded. Subsequently variables were analyzed to describe the age of the patients,
number of sessions,
type and location of AVM,
results and coplications.
A total of 32 AVMs were embolized.
42.%(fifteen) were women and (seventeen) 53.2% men,
(Table 1). The patients were grouped in a range of ages.
The largest group is between 50 and 70 years old,
which comprises 40.6% (13) of the treated patients.
Followed by the group with ages between 20 to 50 years,
being 37.5% (12) of all patients.
Patients younger than 20 years old were 12.5% (4) and those older than 70 years old were 9.4% (3) of the total patients treated,
(Table 2). Four patients also...
40.6% of the patients are asymptomatic,
do not present any associated symptoms or require another treatment to complete the embolization. 59.4 % of the patients needed more than one treatment session to try to complete the embolization and 18.6 % of the patients needed radiosurgery to finish the treatment. Onyx is the most frequently used embolic agent (68.6 %),
both as only agent and in combination with others.
It is worth to notice the use of PHIL,
which although it is a...
