Experience with Management of Intracranial Arachnoid Cysts.

OBJECTIVES: The aim of this study was to analyze the demographics, clinical presentation, and surgical outcome of intracranial arachnoid cysts and to review the surgical options. METHODS: This is a retrospective observational study of 56 cases of symptomatic arachnoid cysts among all age groups treated between 2004 and 2020 at the Bombay Hospital, Mumbai. Endoscopic fenestration, microsurgical cyst excision, and shunt insertion were the interventions performed. Clinical presentation, cyst reduction post-intervention, and complications were studied. The follow-up period varied from 1 month to 16 years. Statistical analysis was done for 43 patients with a minimum of 3 years' follow-up. RESULTS: In all, 75% of patients were <18 years of age. Of these, the majority were between the age of 1 and 10 years. There were 14 cases of temporal, 13 cases of retrocerebellar, 10 cases of quadrigeminal cistern, and 7 cases each of interhemispheric and suprasellar arachnoid cysts. The most common clinical presentation was headache and vomiting. Concomitant hydrocephalus was seen on imaging in 24 cases. Endoscopic fenestration of cyst was the most routinely performed procedure (35 cases). Four patients of endoscopic fenestration underwent a redo endoscopic procedure on follow-up. Post-operative reduction in cyst size was found to be significantly better after endoscopic fenestration (p < 0.05). CONCLUSION: Though the best available treatment for arachnoid cysts remains controversial, surgery has been found to be beneficial in symptomatic cases. Endoscopic fenestration is considered the first-line surgical option and it may be followed by shunt, if necessary. Shunts may be preferred in very young children where there is associated hydrocephalus/macrocephaly.

Moyamoya Vasculopathy in Indian Children: Our Experience.

BACKGROUND: Moyamoya vasculopathy is a chronic progressive vaso-occlusive disease affecting the distal intracranial carotid arteries and their proximal branches. It is an important cause of recurrent strokes in children. Surgical revascularization procedures are now considered as the treatment option for moyamoya vasculopathy. The data from Indian children with moyamoya vasculopathy are limited to a very few studies. STUDY DESIGN: We analyzed the records of children with moyamoya vasculopathy treated at our tertiary care center from 2000 to 2014. Our study population included all patients (aged 0-18 years) with moyamoya disease/syndrome (MMD/MMS). The demographic data, clinical characteristics, imaging, treatment details, and surgical procedures performed were reviewed. RESULTS: A total of 41 patients (females-19, males-22) were identified. Thirty-three (80.48%) had MMD and eight (19.5%) had MMS. The mean age (±standard deviation) at presentation was 6.26 ± 3.79 years (range: 6 months-14 years). Majority had ischemic events at onset; none had hemorrhagic manifestations. Twenty-eight (68.29%) patients underwent surgery (a total of 33 surgical procedures, bilateral in five and unilateral in 23) and 13 (31.7%) were managed conservatively. The median duration of follow-up was 2.2 ± 1.85 years (range: 4 months-7 years). Two/thirteen patients (15%), who were managed conservatively, had recurrent strokes as against none (0/28) in the operated patients. No mortality was observed in our cohort. CONCLUSION: We agree with previous studies that Indian patients with moyamoya vasculopathy differ from their Asian and European counterparts. The availability of expertise in revascularization surgeries in various centers should prompt surgery as an efficient and safe treatment option.
