Abstract
BACKGROUND Vascular malformations (VMs) arise as a result of errors in the process of angiogenesis and are usually present at birth, but may not become apparent until after birth. However, giant VMs of the head and face are uncommon, with few reported cases, and the prognosis for their surgical intervention is unclear. CASE SUMMARY A 12-year-old girl was admitted to the hospital with findings of an enlarged right temporal scalp. After admission, computed tomography (CT) angiography of cerebral ateries showed a right occlusal gap and a right temporal artery venous malformation. Furthermore, cerebral angiography showed a right temporal lobe VM with multiple vessels supplying blood. The patient underwent surgery to remove the malformed vessels and the eroded skull. Two hours after the surgery, the patient's right pupil was dilated, and an urgent CT scan of the skull showed a right subdural haematoma under the incision, which was urgently removed by a second operation. After surgery, we gave continuous antibiotic anti-infection treatment, and the patient recovered well and was discharged two weeks later. CONCLUSION Surgical removal of giant haemangiomas is risky and adequate preoperative (including interventional embolisation) and intraoperative preparations should be made.

Wu EM, Tigre JY, Morcos JJ. Management of a dural arteriovenous fistula versus arteriovenous malformation of the internal auditory canal with radiosurgery. Clin Neurol Neurosurg 2023; 231:107828. [PMID: 37315376 DOI: 10.1016/j.clineuro.2023.107828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Accepted: 06/05/2023] [Indexed: 06/16/2023]
Abstract
We present a case of a 61-year-old male who presented with an 8-month history of left hypacusis, tinnitus, and gait imbalance. MRI showed a vascular lesion in the left internal auditory canal (IAC). Angiogram showed a vascular lesion filling from the ascending pharyngeal and anterior inferior cerebellar artery (AICA) with drainage into the sigmoid sinus suggestive of either a dural arteriovenous malformation (dAVF) vs arteriovenous malformation (AVM) of the IAC. The decision was made to operate to prevent risk of future hemorrhage [1-5]. Endovascular options were not as ideal given access transarterially through the AICA would be risky, access transvenously would be difficult and it was unclear whether this lesion was a dAVF or AVM. The patient underwent a retrosigmoid approach. A tuft of arterialized vessels surrounding CN7/8 was identified and no true nidus was found so it was thought that this lesion was a dAVF. The plan was to clip the arterialized vein as is normally done for dAVF. However, there was engorgement of the vascular lesion upon clipping of the arterialized vein indicating risk of rupture if the clip was left insitu. It was too risky to drill the posterior wall of the IAC to expose the fistulous point more proximally. As a result, 2 clips were placed on the AICA branches. Postoperative angiogram showed some slowing of the vascular lesion but it was still present. Given the AICA feeder, it was decided that this lesion was a dAVF with mixed features of an AVM and the decision was made to gamma knife the lesion 3 months postoperatively. Patient underwent gamma knife targeting the dura superior to the IAC with 18 Gy at the 50 % isodose line. At 2 years follow up, the patient's symptoms improved and he remained neurologically intact. Imaging revealed complete obliteration of the dAVF. This case illustrates the step by step management of a dAVF that mimicked a true pial AVM. The patient consented to the procedure and participating in this surgical video.

Embolization as stand-alone strategy for pediatric low-grade brain arteriovenous malformations. J Stroke Cerebrovasc Dis 2023; 32:107137. [PMID: 37068327 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 04/10/2023] [Accepted: 04/12/2023] [Indexed: 04/19/2023] Open
Abstract
OBJECTIVES We evaluated the safety and efficacy of endovascular embolization as first-line stand-alone strategy for the treatment of low-grade brain arteriovenous malformations (bAVMs) (Spetzler Martin [SM] grade I and II) in pediatric patients. In addition, we assessed the predictors of procedure-related complications and radiographic complete obliteration in a single session. MATERIAL AND METHODS We conducted a single center retrospective cohort study of all pediatric (≤18 years) patients who underwent embolization as a stand-alone strategy for low-grade bAVMs between 2010 and 2022. Safety was measured by procedure-related complications and mortality. Efficacy was defined as complete angiographic obliteration after the last embolization session. RESULTS Sixty-eight patients (41 females; median age 14 years) underwent a total of 102 embolization sessions. There were 24 (35%) SM grade I lesions and 44 (65%) grade II. Six procedure-related complications (5.8% of procedures) were observed and no deaths were reported. All the complications were intraoperative nidus ruptures. A single draining vein was the only significant predictor of procedure-related complications (OR=0.10; 95% CI 0.01 - 0.72; p=0.048). Complete angiographic obliteration was achieved in 44 patients (65%). In 35 patients (51%) the bAVM was completely occluded in one session. The bAVM nidal size was a predictor of complete obliteration in one session (OR=0.44; 95% CI, 0.21-0.80; p=0.017). CONCLUSION Endovascular treatment as a stand-alone strategy for pediatric low-grade bAVMs is an adequate first-line approach in high volume centers with endovascular expertise. Nidal size evaluation is relevant in order to optimize patient selection for embolization as a stand-alone treatment modality.

Abstract
OBJECTIVE Central nervous system (CNS) metastasis originating from gynecological cancer is a very rare and late manifestation of the disease. Therefore, there is still limited data on prognostic factors for survival. The objective of the present study is to identify prognostic factors for survival in patients with CNS metastasis originating from gynecological cancer. STUDY DESIGN The present retrospective study analyzed the patients with gynecological cancers who were treated due to CNS metastases between January 1999 and December 2019 at Istanbul University Hospital. RESULTS Forty-seven patients with CNS metastasis of gynecological origin were included in the study. The median age at the time of CNS metastasis was 59 (range 34-93). The median time from initial cancer diagnosis to CNS metastasis was 24.9 (range: 0-108.2) months. Most patients had epithelial ovarian cancer (EOC) (76.6%), followed by endometrial cancer (EC) (14.8%), cervical cancer (CC) (4.3%), and vulvar cancer (VC) (4.3%). By multivariate analysis, the presence of extracranial metastasis (HR: 5.10; 95% CI: 1.71-15.18), Eastern Cooperative Oncology Group (ECOG) performance status ≥3 (HR: 2.92; 95% CI: 1.36-6.26), palliative care only for the treatment of CNS metastasis (HR: 1.47; 95% CI: 0.58-4.11), and treatment-free interval (TFI) <6 months (HR: 2.74; 95% CI: 1.23-6.08) were independent factors that associated with worse survival. CONCLUSION Patients with CNS metastasis who have favorable prognostic factors are considered to be appropriate candidates for aggressive and long-term treatment strategies. Extracranial metastasis, ECOG performance status, treatment history of CNS metastasis, and TFI were determined as independent prognostic factors that improved survival. TFI might be taken into account as a prognostic factor for patients with CNS metastasis in gynecological cancer.

Abstract
BACKGROUND Meningiomas have vascular supply from the tumor attachment on the dura mater. Gamma Knife radiosurgery (GKS) is known to have a vascular obliterating effect. This study aims to determine the benefits of high-dose irradiation to the tumor attachment compared to conventional dose planning in the long-term control of tumor growth with GKS. METHODS Two different dose plannings were retrospectively compared in 75 patients with meningioma treated with GKS as a primary treatment. Forty-three patients were irradiated over 20 Gy to the tumor attachment. The remaining 32 patients were treated with conventional-dose planning. Tumor growth control, reduction of enhancement on the gadolinium-enhanced magnetic resonance imaging (MRI), and neurological status were retrospectively assessed. RESULTS The maximum dose on the tumor attachment was significantly higher in the high-dose group (23 Gy) than in the conventional group (16 Gy). The tumor margin was irradiated with the median of the 50% isodose line in both groups. The prescription doses resulted in 14 Gy and 12 Gy, respectively. The tumor control rate achieved 91% in both groups during the median follow-up period of 54 months. A decrease of enhancement on follow-up MRI was noted in one patient in each group. Kaplan-Meier analysis revealed no statistical difference in the progression-free survival between the two groups. The number of patients with improved neurological status showed no statistical difference. CONCLUSIONS No obvious benefit of high-dose irradiation to the tumor attachment and margin was found in tumor control and neurological status in the long term.

Abstract
Stereotactic radiosurgery (SRS) is generally considered a substitute for cranial cavernous malformations (CCMs). However, prognostic factors for post-radiosurgery CCM rebleeding and adverse radiation effects have not been well evaluated, and the effect of timing and optimal treatment remains controversial. Therefore, this study evaluated prognostic factors for post-radiosurgical rebleeding and focal edematous changes in 30 patients who developed symptomatic intracranial hemorrhage due to solitary non-brainstem CCM and received linear accelerator (LINAC) SRS in a single medical center from October 2002 to June 2018. An overall post-radiosurgical annual hemorrhage rate with 4.5% was determined in this study. In addition, a higher marginal dose of >1600 centigray and earlier LINAC SRS intervention were correlated with a significantly lower post-radiosurgical annual hemorrhage rate. A lesion size larger than 3 cm3 and a coexisting developmental venous anomaly were significant risk factors for post-radiosurgical focal brain edema but mostly resulted in no symptoms and were temporary. This study demonstrated the efficacy of LINAC SRS in preventing CCM rebleeding and suggests that earlier radiosurgery treatment with a higher dose for non-brainstem symptomatic CCMs be considered.

Abstract
OBJECTIVE Brain arteriovenous malformations (AVMs) carry a risk of rupture and subsequent morbidity or mortality unless fully treated. AVMs in pediatric patients are known to occasionally recur after obliteration. The objective of this study was to characterize the risk of AVM recurrence following angiographically confirmed obliteration in children. METHODS Consecutive pediatric AVMs treated at a single center were identified from a prospective database. Patients with angiographically confirmed AVM obliteration following treatment were included in this study. Associations between AVM recurrence and patient or procedural factors were characterized using the two-tailed Fisher exact test or Mann-Whitney U-test. A literature search was conducted using PubMed, Scopus, Embase, and the Clarivate Web of Science with defined search criteria, and eligible studies were included alongside this study cohort in a meta-analysis. Rates of AVM recurrence following obliteration were pooled across studies with a random-effects model and reported with 95% confidence intervals (CIs). RESULTS Recurrence after angiographic confirmation of AVM obliteration was observed in 10.4% (7/67) of pediatric AVMs treated at the authors' center. Patients with recurrent AVMs were significantly younger than those without recurrence (p = 0.002). In the meta-analysis, which included 1134 patients across 24 studies, the rate of recurrence was 4.8% (95% CI 3.0%-6.7%). The rate of AVM recurrence following radiosurgery was 0.7% (95% CI 0%-1.6%), which was significantly lower than the 8.5% rate (95% CI 5.0%-12.0%) following microsurgery. CONCLUSIONS Recurrence of obliterated brain AVMs is common in children. Recurrence is more common in young children and following microsurgery.

Abstract
OBJECTIVE The major concern about ruptured arteriovenous malformations (rAVMs) is recurrent hemorrhage, which tends to preclude stereotactic radiosurgery (SRS) as a therapeutic modality for these brain malformations. In this study, the authors aimed to clarify the role of SRS for rAVM as a stand-alone modality and an adjunct for a remnant nidus after surgery or embolization. METHODS Data on 410 consecutive patients with rAVMs treated with SRS were analyzed. The patients were classified into groups, according to prior interventions: SRS-alone, surgery and SRS (Surg-SRS), and embolization and SRS (Embol-SRS) groups. The outcomes of the SRS-alone group were analyzed in comparison with those of the other two groups. RESULTS The obliteration rate was higher in the Surg-SRS group than in the SRS-alone group (5-year cumulative rate 97% vs 79%, p < 0.001), whereas no significant difference was observed between the Embol-SRS and SRS-alone groups. Prior resection (HR 1.78, 95% CI 1.30-2.43, p < 0.001), a maximum AVM diameter ≤ 20 mm (HR 1.81, 95% CI 1.43-2.30, p < 0.001), and a prescription dose ≥ 20 Gy (HR 2.04, 95% CI 1.28-3.27, p = 0.003) were associated with a better obliteration rate, as demonstrated by multivariate Cox proportional hazards analyses. In the SRS-alone group, the annual post-SRS hemorrhage rates were 1.5% within 5 years and 0.2% thereafter and the 10-year significant neurological event-free rate was 95%; no intergroup difference was observed in either outcome. The exclusive performance of SRS (SRS alone) was not a risk for post-SRS hemorrhage or for significant neurological events based on multivariate analyses. These results were also confirmed with propensity score-matched analyses. CONCLUSIONS The treatment strategy for rAVMs should be tailored with due consideration of multiple factors associated with the patients. Stand-alone SRS is effective for hemorrhagic AVMs, and the risk of post-SRS hemorrhage was low. SRS can also be favorably used for residual AVMs after initial interventions, especially after failed resection.

Abstract
Vascular malformations and vascular tumors comprise the two specific subsets of vascular anomalies that arise as a result of disorganized angiogenesis and neoplasm, respectively. Malformations are separate entities from vascular tumors (e.g., hemangiomas) and are recognized by the International Society for the Study of Vascular Anomalies (ISSVA) as such. Vascular malformations are classified into four main groups: simple, combined, anomalies of major vessels, and those associated with other vascular anomalies. Vascular tumors are neoplastic growths of blood vessels and are morphologically and molecularly distinct from malformations but can arise in the head and neck and have syndromic association. Head and neck vascular anomalies are not uncommon in the pediatric population and require special care in the workup, diagnostic imaging and clinical care. The purpose of this manuscript is to discuss the diagnosis and management of the most common intracranial and extracranial vascular malformations and tumors in the head and neck in children and adolescents.

Abstract
Persistent vasculature abnormalities contribute to an altered CNS microenvironment that further compromises the integrity of the blood-brain barrier and exposes the brain to a host of neurotoxic conditions. Standard radiation therapy at conventional (CONV) dose rate elicits short-term damage to the blood-brain barrier by disrupting supportive cells, vasculature volume and tight junction proteins. While current clinical applications of cranial radiotherapy use dose fractionation to reduce normal tissue damage, these treatments still cause significant complications. While dose escalation enhances treatment of radiation-resistant tumors, methods to subvert normal tissue damage are clearly needed. In this regard, we have recently developed a new modality of irradiation based on the use of ultra-high-dose-rate FLASH that does not induce the classical pathogenic patterns caused by CONV irradiation. In previous work, we optimized the physical parameters required to minimize normal brain toxicity (i.e., FLASH, instantaneous intra-pulse dose rate, 6.9 · 106 Gy/s, at a mean dose rate of 2,500 Gy/s), which we then used in the current study to determine the effect of FLASH on the integrity of the vasculature and the blood-brain barrier. Both early (24 h, one week) and late (one month) timepoints postirradiation were investigated using C57Bl/6J female mice exposed to whole-brain irradiation delivered in single doses of 25 Gy and 10 Gy, respectively, using CONV (0.09 Gy/s) or FLASH (>106 Gy/s). While the majority of changes found one day postirradiation were minimal, FLASH was found to reduce levels of apoptosis in the neurogenic regions of the brain at this time. At one week and one month postirradiation, CONV was found to induce vascular dilation, a well described sign of vascular alteration, while FLASH minimized these effects. These results were positively correlated with and temporally coincident to changes in the immunostaining of the vasodilator eNOS colocalized to the vasculature, suggestive of possible dysregulation in blood flow at these latter times. Overall expression of the tight junction proteins, occludin and claudin-5, which was significantly reduced after CONV irradiation, remained unchanged in the FLASH-irradiated brains at one and four weeks postirradiation. Our data further confirm that, compared to isodoses of CONV irradiation known to elicit detrimental effects, FLASH does not damage the normal vasculature. These data now provide the first evidence that FLASH preserves microvasculature integrity in the brain, which may prove beneficial to cognition while allowing for better tumor control in the clinic.

Abstract
Intracranial radiotherapy has been improved, primarily because of the development of stereotactic approaches. While intracranial stereotactic body radiotherapy is mainly indicated for treatment of benign or malignant tumors, this procedure is also effective in the management of other neurological pathologies; it is delivered using GammaKnife® and linear accelerators. Thus, brain arteriovenous malformations in patients who are likely to experience permanent neurological sequelae can be managed by single session intracranial stereotactic body radiotherapy, or radiosurgery, in specific situations, with an advantageous benefit/risk ratio. Radiosurgery can be recommended for patients with disabling symptoms, which are poorly controlled by medication, such as trigeminal neuralgia, and tremors, whether they are essential or secondary to Parkinson's disease. This literature review aims at defining the place of intracranial stereotactic body radiotherapy in the management of patients suffering from non-tumoral refractory neurological pathologies. It is clear that the multidisciplinary collaboration of experienced teams from Neurosurgery, Neurology, Neuroradiology, Radiation Oncology and Medical Physics is needed for the procedures using high precision radiotherapy techniques, which deliver high doses to locations near functional brain areas.
