Surgical Management of Giant Intracranial Aneurysms: Overall Results of a Large Series.
To review and discuss surgical treatment options for giant intracranial aneurysms (GIAs), focusing on indications, technical aspects, and results, along with some illustrative cases. ⋯ Microneurosurgical techniques still maintain a significant role for most GIAs, with a high durability and acceptable rate of morbidity and mortality. Clip reconstruction is the first-line surgical treatment option, whereas bypass is indicated in cases of planned or unplanned sacrifice of the parent artery to prevent long-term ischemic complications.

Tumors presenting with drug-resistant seizures are termed as long-term epilepsy-associated tumors (LEATs). LEATs are more common in the temporal lobe, occur predominantly in pediatric age, and focal neurological deficits are rare. In this article, we aim to highlight our surgical experience in terms of seizure outcome among LEATs and discuss the factors affecting outcome. ⋯ A shorter duration of symptoms, younger age of the patient, partial/focal seizures, and gross total excision were predictors of a good seizure outcome. Histopathology of the tumor does not affect the outcome when one compares glioneuronal tumors with non-glioneuronal tumors.

Direct carotid-cavernous fistulas (DCCF) develop due to breach in the integrity of the wall of the internal carotid artery, and its localization can sometimes be difficult due to rapid high flow shunts. We hypothesized that 3D rotational angiography could locate the fistula site accurately, where an interrupted rim of the carotid wall would be silhouetted against opacified vascular structures. This finding was described as a broken-rim sign, and in this study, we assessed the utility of this sign in the localization of the shunt point of DCCF. ⋯ Our study highlights the role of 3D rotational angiogram and analysis of the carotid wall in the localization of the shunt site in DCCF. The broken-rim sign accurately points to the location of the fistula.

Hydranencephaly is a congenital central nervous system disorder characterized by the complete or near-complete absence of the cerebral cortex and basal ganglia. Because of its rarity, data on the clinical features and survivorship remain sparse. We aim to determine the clinical features and survivorship of a cohort of patients with hydranencephaly. ⋯ In this large single-center retrospective cohort of patients with hydranencephaly, novel findings are presented regarding the clinical manifestations and survivorship of this condition.

Conventional understanding of obesity demonstrates negative consequences for overall health, whereas more modern studies have found that it can provide certain advantages. The current literature on the effect of body mass index (BMI) in subarachnoid hemorrhage (SAH) is similarly inconsistent. ⋯ The overweight group exhibited strikingly lower odds of death and poor outcome compared with the normal weight group, whereas the obese group demonstrated the opposite. These associations persisted in a multivariable model; thus, BMI can be considered an important predictor of outcome after SAH.
