“…

SUMMARY -Endovascular therapy is a therapeutic option that can achieve total obliteration of cerebral arteriovenous malformations (AVMs (OR: 50.9; 0; P = 0.000), and opposing factors,(3)(4)(5)(6)4; P = 0.002) and afferences of more than two vessels of the Willis polygon (OR: 7.0; P = 0.038). An AVM diameter smaller than 3 cm is a predictive factor of total obliteration.

“…Its diagnostic yield and safety for children and adults has been proved for almost every aspect of cerebrovascular pathology [22][23][24][25][26][27][28][29] . The role of superselective angiography for the evaluation of newly formed collaterals after revascularization procedures in children with moyamoya, as well as its safety despite catheterization of the vasospasm-prone middle meningeal and temporal arteries or of the small-calibre anterior choroidal artery for an endovascular approach to distal aneurysms, was also reported by other groups [30][31][32][33][34] .…”

The angioarchitecture of the so-called moyamoya vessels in children has not been explicitly analyzed. We aimed to investigate the precise anatomy of the vascular anastomotic networks in patients with childhood moyamoya disease. Six children diagnosed with moyamoya disease for the first time underwent an angiographic investigation with selective and superselective injections. We recorded the arterial branches feeding the moyamoya anastomotic networks, their connections and the recipient vessels. Depending on the level of the steno-occlusive lesion, the feeding vessels included the medial striate arteries, the perforators of the choroidal segment of the carotid, the uncal artery, the medial and lateral branches of the intraventricular segment of the anterior choroidal artery, perforators of the communicating segment, the superior hypophyseal arteries, the prechiasmal branches of the ophthalmic artery, the ethmoidal arteries and the dural branches of the cavernous carotid. Through connections, which are described, the recipient vessels were the lateral striate arteries and the middle cerebral, the medial striate arteries and the anterior cerebral, medullary arteries around the ventricular system, anterior temporal branches of the middle cerebral, orbitofrontal and frontopolar branches of the anterior cerebral, as well as other cortical branches of the anterior and middle cerebral territories. The use of high quality selective and superselective angiography enabled us to clearly demonstrate for the first time aspects of the microangiographic anatomy of the moyamoya anastomotic network previously only vaguely or incompletely described.

“…Endovascular embolization is important in multimodality treatment of AVMs, particularly for patients with a nidus volume of more than 10 ml. 6,13,15,21) Pre-surgical embolization is particularly effective for giant occipital AVMs, because the nidus is usually attached to both the falx and tentorium and receives blood supply from the dural feeders. Both pial and dural feeders are candidates for embolization, but embolization of the dural feeders is reliable and safe, allowing precise obliteration of the compartment of the nidus being fed.…”

Two patients with giant occipital arteriovenous malformation (AVM) underwent microsurgical treatment among 294 patients with intracranial AVM treated between 1981 and 2004. The patients were aged 52 and 65 years and showed common symptoms consisting of long-term frequent migraine-like headaches with visual aura and recent homonymous hemianopia. Common neuroimaging findings were abundant dural feeders plus feeders from the posterior, middle, and anterior cerebral arteries, and deep drainers to the galenic system. Both patients underwent preoperative staged embolization and total microsurgical removal of the nidus with a neuronavigation system. Both patients returned to ordinary life without the need for assistance. These findings emphasize that giant occipital AVM, even if unruptured, is surgically treatable with acceptable morbidity.
