BACKGROUND: AVM surgery is particularly demanding as for the bleeding control of small deep white matter vessels during and after the removal of the nidus, this representing probably one of the most critical moments of AVMs surgery. OBJECTIVE: of the present manuscript is to describe a useful technique based on the use of tweezers to temporarily stop the blood flow followed by coagulation with thulium laser. METHODS: Twenty patients with unruptured cerebral AVMs underwent surgical treatment...

BACKGROUND AND IMPORTANCE: Giant cavernous malformations (GCM) are low flow, angiographically occult vascular lesions, with a diameter >4 cm. Cerebellar GCMs are extremely rare, with only seven cases reported based on English literature. These lesions are most commonly seen in the pediatric age group, which is known to have an increased risk of hemorrhage, being surgery clearly recommended. CLINICAL PRESENTATION: An 18-month-old girl presented with a 6-month history of cervical torticollis and upper extremities clumsiness...

BACKGROUND: Some intractable cases of postcraniotomy infection, which can involve compromised skin, an open frontal air sinus, and residual epidural dead space, have been reported. In such cases, reconstructing the scalp and skull is challenging. METHODS: Between 2009 and 2016, the author treated 12 patients with recalcitrant postcraniotomy surgical site infections with latissimus dorsi (LD) free flaps. The patients' ages ranged from 37 to 79 years (mean, 63.5 years), and their underlying diseases included subarachnoid hemorrhaging (n = 5), brain tumors (n = 4), and cerebral arteriovenous malformations (n = 3)...

Cerebral aneurysms in complex anatomical locations and intraoperative rupture of aneurysms are challenging for neurosurgeons and anaesthetists alike. Mechanical and non-mechanical methods to reduce blood flow into aneurysms are well-recognised techniques to facilitate aneurysm exclusion from the circulation. Mechanical methods like temporary clipping of parent arteries, carotid artery ligation and endovascular balloon occlusion are commonly used in clinical practice. However, non-mechanical techniques such as rapid ventricular pacing and adenosine-induced cardiac standstill with hypotension are still emerging strategies...

OBJECTIVE: Cerebrovascular malformation classification has revealed intermediary lesions that warrant further review due to their unusual presentation and management. We present two cases of arteriovenous malformations (AVMs) associated with a developmental venous anomaly (DVA), and discuss the efficacy of previously published management strategies. METHODS: Two cases of AVMs associated with DVA were identified and a literature search for published cases between 1980 and 2016 was conducted...

OBJECTIVE Deep medial parietooccipital arteriovenous malformations (AVMs) and cerebral cavernous malformations (CCMs) are traditionally resected through an ipsilateral posterior interhemispheric approach (IPIA), which creates a deep, perpendicular perspective with limited access to the lateral margins of the lesion. The contralateral posterior interhemispheric approach (CPIA) flips the positioning, with the midline positioned horizontally for retraction due to gravity, but with the AVM on the upper side and the approach from the contralateral, lower side...

INTRODUCTION: Cerebral cortical venous aneurysm also known as cerebral varix is a rare entity that usually occurs in relation to high-flow draining veins of arteriovenous fistulas, arteriovenous malformations, and venous angioma. Isolated cerebral varix is an extremely rare entity. CASE REPORT: We present a 1-year-old male with isolated cerebral varix. During follow-up, the varix thrombosed spontaneously without causing any neurological deficits. CONCLUSION: To the best of our knowledge, spontaneous asymptomatic thrombosis of an isolated cerebral varix without any clinical finding was reported for the first time in the literature...

BACKGROUND: Neurosurgical application of indocyanine green (ICG) videography prior to performing a dural opening has been reported as transdural ICG videography and used during surgery of meningiomas associated with venous sinuses, as well as cranial and spinal arteriovenous malformations. However, its use for a superficial temporal artery to middle cerebral artery (STA-MCA) bypass has not been reported. METHODS: We performed a retrospective analysis of medical records of patients who underwent a transdural ICG videography technique during STA-MCA bypass procedures performed between January 2012 and March 2015...

Background and purpose Digital subtraction angiography is the current gold standard for diagnosing as well as the follow-up of cerebral arteriovenous malformations. However, as it is invasive, relatively expensive and time-consuming, a non-invasive alternative is of interest. We aimed to evaluate the feasibility of time resolved computed tomography angiography (TR-CTA) in a series of five diagnosed cranial arteriovenous malformation patients, demonstrated by conventional digital subtraction angiography with respect to acquisition, depiction of angiographic phases and radiation exposure...

PURPOSE: Radiosurgery is an established technique to treat Cerebral Arteriovenous Malformations (AVMs). Obliteration of larger AVMs (>10-15 cm(3) or diameter > 3 cm) in a single session is challenging with current radiosurgery platforms due to toxicity. We present a novel technique of multi-stage stereotactic radiosurgery (SRS) for large intracranial arteriovenous malformations (AVM) using the Gamma Knife system. MATERIALS/METHODS: Eighteen patients with large (>10-15 cm(3) or diameter ⩾3 cm) AVMs, which were previously treated using a staged SRS technique on the Cyberknife platform, were retrospectively selected for this study...

INTRODUCTION: Intracranial artery-to-artery antegrade revascularization is a poorly recognized entity, more so when it involves main stem arteries. The etiology, appearance, and significance of this condition are not described in the literature. CASE PRESENTATION: We describe a case of spontaneous revascularization of a chronically occluded middle cerebral arterial branch by collaterals from the proximal segment reconstituting distal flow, mimicking a brain arteriovenous malformation in a 9-year old boy...

Superficial arteriovenous malformations (AVMs) with favorable Spetzler-Martin grading are amenable to primary surgical resection. Careful preoperative workup including preoperative angiograms is essential to identify feeding artery aneurysms and deep venous drainage. The authors present a 37-year-old female who presented with a Spetzler-Martin Grade II right parietal superficial AVM with a 5-mm feeding artery aneurysm from the posterior cerebral artery. Given the risk of hemorrhage, the AVM was resected completely without any complications...

A 46-year-old male presented with an incidentally discovered left ventricular body arteriovenous malformation (AVM). It measured 2 cm in diameter and had drainage via an atrial vein into the internal cerebral vein (Spetzler-Martin Grade III, Supplementary Grade 4). Preoperative embolization of the posterior medial choroidal artery reduced nidus size by 50%. Subsequently, he underwent a right-sided craniotomy for a contralateral transcallosal approach to resect the AVM. This case demonstrates strategic circumferential disconnection of feeding arteries (FAs) to the nidus, the use of aneurysm clips to control large FAs, and the use of dynamic retraction and importance of a generous callosotomy...

Grade III Spetzler-Martin arteriovenous malformations (AVMs) are a distinct subgroup of brain AVMs. Their variety in terms of location, type of venous drainage, and size makes them the most heterogenous group in the AVM classification. The surgical risk of treatment is also variable depending on the specifics of a given Grade III AVM. In this video illustration, the authors describe the technical nuances of surgical resection of a very complex Grade III left posterior temporal AVM. According to supplementary grading, the unruptured aspect and patient age give this lesion a Grade III; therefore, the combined grading gives the patient a score of 6, which puts him at moderate risk of morbidity for surgery...

The management of arteriovenous malformations (AVMs) of the corpus callosum and choroidal fissure is challenging because they commonly receive arterial feeders from the anterior and posterior circulation, and drain to deep veins. In this video the authors present the case of a 20-year-old man who presented with acute onset of headache, loss of consciousness, and nuchal rigidity. Computed tomography, MRI, and cerebral angiography performed in tandem revealed a ruptured, large, Grade IV AVM of the corpus callosum and choroidal fissure with two groups of arterial feeders: one from the pericallosal artery and the other from the medial and lateral posterior choroidal arteries...

This is the case of a 14-year-old female who presented with headache and seizures. Cranial magnetic resonance imaging revealed an arteriovenous malformation (AVM) located at the posterior portion of the right-sided fusiform gyrus. Cerebral angiography showed that the AVM was fed mainly by branches from the inferior temporal trunk of the posterior cerebral artery. The main venous drainage was to the right transverse sinus through the tentorial vein. The AVM was totally excised through the paramedian supracerebellar-transtentorial approach with the patient in a semisitting position...

Faustina N A Sackey, Nathaneal R Pinsker, Benjamin N Baako
Cerebral arteriovenous malformations (AVMs) are abnormal tangling between brain arteries and veins causing an arteriovenous shunt called nidus with an intervening network of vessels from the region of formation and spans through the brain. AVM effect is debilitating to the affected individual due to associated persistent intracerebral hemorrhage, resulting in significant occurrences of seizures and neurological damage. Recent innovative treatments involve a combination of embolization (Embo) procedures followed by stereotactic radiosurgery (SRS), designed to optimize less-invasive practice for the obliteration of the AVMs...
