“…Because of the presence of pediatric patients with ocular retinoblastoma, the mean age of the study participants was 5-10 years lower than the average age of the patients in similar studies [14][15][16][17][18][19][20][21]. In this study, women constituted nearly half of the patients which is incompatible with gender distribution of the related previous studies [14][15][16][17].…”

Background and Aim: Endovascular neurosurgery is widely accepted as a useful modality for the management of neurovascular disorders. This retrospective study aimed to evaluate the causes of diagnostic and therapeutic neuroendovascular procedures, as well as the prevalence, type, location and management of vascular pathologies observed in Firoozgar Hospital, Tehran City, Iran. Methods and Materials/Patients: In this study, we analyzed the causes and outcomes of the neuroendovascular procedures during 18 months from

“…Most patients (74%) with seizures were associated with the temple type because frontal, temporal, and parietal locations are known predictors of initial presentation of epilepsy. 15 In contrast, chronic headache, often accompanying AVMs in the occipital lobe, was exclusively found within the temple type group (100%) and not within the occipital type group. 15,16…”

BACKGROUND AND PURPOSE: Arterial transdural blood supply is a rare angiographic phenomenon in cerebral AVMs. This study aimed to evaluate angiographic transdural blood supply characteristics and to describe the clinical peculiarities of these lesions. MATERIALS AND METHODS: A prospective AVM data base of 535 patients, enrolled from 1990 to 2016, was analyzed retrospectively. Clinical information was reviewed through patients' medical charts and radiologic studies. Patients with previous AVM treatment were excluded (n ϭ 28). RESULTS: Patients with (n ϭ 32, male/female ratio ϭ 10:22; mean age, 46 Ϯ 15 years; range, 13-75 years) and without transdural blood supply (n ϭ 475, male/female ratio ϭ 260:215; mean age, 40 Ϯ 18 years; range, 2-87 years) did not show significant differences in clinical presentation (age, hemorrhage, seizures, chronic headache). The predominant nidus size in patients with transdural blood supply was Ն30 mm, with significantly more patients with large AVMs (Ͼ60 mm, P ϭ .001). To describe the transdural blood supply, we used 3 grades based on the angiographic transdural blood supply proportion and intensity of AVM nidus perfusion (I-III). Fifty-seven percent of patients with chronic headache had a strong and substantial transdural nidus perfusion (III) and a high-flow transdural blood supply. CONCLUSIONS: Cerebral AVMs with transdural blood supply represent a rare and heterogeneous subgroup. Lesions can be graded by quantifying the transdural blood supply of the nidus and by capturing hemodynamic characteristics. The broad spread of angiographic features and comparable clinical patterns of patients with or without transdural blood supply raises questions about the relevance of the transdural blood supply to the natural history risk of an AVM and the intention for treatment.

“…Some authors have suggested that AVMs located in deep regions, such as the basal ganglia, the periventricular or intraventricular space, are at increased risk of bleeding . Several locations of AVMs were associated with a higher occurrence of hemorrhage at the initial presentation, such as the cerebellum, brainstem, temporal lobe, insula, corpus callosum, the basal ganglia, and ventricles .

Objective To assess the relationship of the grade of unruptured and untreated Brain Arteriovenous Malformations (AVMs), with the risk of subsequent stroke and death during follow‐up. Methods This prospective study was drawn from a cohort of adult patients with unruptured AVMs, who participated in the conservative treatment arm (medical management only for headache or seizures) of the randomized clinical trial of unruptured brain AVMs (ARUBA study). The grade of AVMs (Spetzler–Martin scale) was dichotomized into categories: AVMs of grades I and II were considered low grade; AVMs of grades III and IV were considered high grade. There were no grade V AVM patients in ARUBA. The primary outcome was symptomatic stroke (hemorrhagic or ischemic – documented by imaging) or death. Results The conservative treatment group had 123 patients (“as treated” analysis). 71 (57.7%) had lesions characterized for this analysis as low‐grade lesions and 52 (42.2%) as high grade. From the total of 10 (8.13%) primary outcomes, three occurred (4.22%) in low‐grade AVMs and seven (13.46%) in high‐grade AVMs (P = 0.0942). Interpretation Statistical analysis of the cohort of patients with unruptured and untreated AVMs from ARUBA study showed that the graduation categories (Spetzler–Martin grades) were not associated with the outcome of subsequent stroke or death.
