To review the symptoms and progression of dural arteriovenous fistulas (AVFs) correlate findings with various angiographic patterns.Patterns venous drainage allowed classification AVFs into five types: type I, located in main sinus, antegrade flow; II, reflux sinus (IIa), cortical veins (IIb), or both (IIa + b); III, direct without ectasia; IV, V, spinal drainage.Type I had a benign course. In induced intracranial hypertension 20% cases, hemorrhage 10%. Hemorrhage was present 40% cases III...
✓ Embolization was used to reduce the size of brain arteriovenous malformations (AVMs) prior radiosurgical treatment in 125 patients who were poor surgical candidates or had refused surgery. Of these patients, 81% suffered hemorrhage, and 22.4% undergone at another institution. According Spetzler—Martin scale, AVMs Grade II 9.6%, III 31.2%, IV 30.4%, Grades V VI 28.8% cases. Most embolizations performed using cyanoacrylate delivered by flow-guided microcatheters. Radiosurgery a linear...
Seventy-one intracranial aneurysms were treated by endovascular techniques, with the placement of minicoils inside aneurysmal sac. Most manifest hemorrhage (67 cases), and 43 these within first 3 days after presentation. At 1-year follow-up examination, outcome was scored as good in 84.5% cases, but morbidity mortality rates 4.2% 11.3%, respectively. Twenty-nine anterior circulation 42 posterior treated. In this series, 23 patients classified Hunt Hess neurological Grade I, 27 II, 12 III,...
A retrospective study was carried out on 13 patients with intracranial dural arteriovenous fistulas (DAVFs) who presented isolated or associated signs of hypertension.Nine symptoms hypertension at the time diagnosis. Ocular fundoscopy available in 12 showed bilateral papilloedema eight and optic disk atrophy four. Clinical evolution particularly noticeable five because chronic (two patients) acute (after lumbar shunting puncture: three patients, one death) tonsillar herniation.Two had a type...
The clinical and angiographic features of 46 vertebral arteriovenous fistulas (AVFs) seen during a 12-year period (45 patients) were reviewed. Fourteen patients asymptomatic, with AVF discovered at routine examination. Specific symptoms presentation in the other tinnitus (n = 21), vertigo 6), neurologic deficit 3), pain 2). Of AVFs, 19 (41%) caused by trauma 27 (59%) spontaneous. fistula was found C-1 to C-2 21 (46%) cases, C-5 five (11%), below 20 (44%). Thirty-four (35 AVFs) treated...
PURPOSE: To determine whether the blood flow abnormalities frequently associated with arteriovenous malformations (AVMs) can alter functional magnetic resonance (MR) imaging evaluation of language lateralization and reorganization function occurs in patients brain AVMs. MATERIALS AND METHODS: Eleven left-hemisphere AVMs 10 age-matched control subjects were examined 1.5-T oxygen level–dependent (BOLD) MR imaging. Verbal fluency, sentence repetition, story listening tasks performed. The...
Abstract Seven cases of vein Galen aneurysms treated by percutaneous transvenous endovascular occlusion the aneurysmal are presented. In one case, approach was via femoral vein, and in other six cases, jugular vein. All malformations were multipedicular and, additionally, seven there an intervening arterial-arterial network between posterior thalamoperforating arteries wall venous aneurysm. This fistulous interpreted as purely arterial not associated arteriovenous malformation. For this...
Background and Purpose Embolization is the first-line treatment for dural arteriovenous fistulas (dAVF). The precipitating hydrophobic injectable liquid (PHIL) embolic agent a non-adhesive copolymer with specific features endovascular behavior. This study assessed its safety efficacy in prospective real-life cohort. Methods PHIL-dAVF was single-arm open-label observational multicenter conducted between October 2017 November 2019 14 European centers. Patients single intracranial dAVF intended...
✓ The aim of this study was to evaluate the role endovascular treatment for intracranial mycotic aneurysms. clinical and angiographic features three patients with endocarditic vegetation (two Streptococcus viridans one Staphylococcus ) were reviewed retrospectively. Patients selected according setting aneurysm location. In two cases, selective catheterization a distal middle cerebral posterior artery branch microcatheter followed by superselective amobarbital testing parent vessel...
Three cases of direct arteriovenous fistulas the scalp (two involving cirsoid aneurysms) are presented. All three patients were treated with puncture venous pouch and injection absolute ethyl alcohol during compression outflow fistula. Two cured this treatment alone. The third patient, a very high-flow giant fistula, required glue to close fistula subsequent surgical extirpation resulting hard mass lesion.
<h3>BACKGROUND AND PURPOSE:</h3> The introduction of liquid embolic agents has revolutionized endovascular approach to cranial vascular malformations. aim the study was retrospectively assess efficacy and safety Precipitating Hydrophobic Injectable Liquid (PHIL), a new nonadhesive agent, in treatment patients with dural arteriovenous fistulas. primary end point rate complete occlusion Secondary points included incidence adverse events clinical status at 3-month follow-up. <h3>MATERIALS...
Internal Jugular Veins (IJVs) are the principle outflow pathway for intracranial blood in clinostatism condition. In seated position, IJVs collapse, while Vertebral (VVs) increase venous and partially compensate drainage. Spinal Epidural an additional drainage position. Colour- Doppler-Sonography (CDS) examination is able to demonstrate VVs different postural respiratory conditions. The purpose of this study was evaluate CDS quantification cerebral (CVF) healthy subjects patients with...
Stereotactic radiosurgery (RS) is an effective tool in treating brain arteriovenous malformations (AVMs). Careful study of AVM angiographic characteristics may improve results.To report the long-term outcomes Gamma Knife RS (GKRS) AVMs, focusing on how angioarchitectural and hemodynamic parameters AVMs affect post-RS results.This was a retrospective, longitudinal 697 consecutive GKRS treatments 662 patients performed at single center between 1993 2005. The mean age 37 years; median volume...
