Microsurgical training has become an obligatory part of many neurosurgical training programs. ⋯ The dry off-the-job training showed to be readily available and can be helpful for microsurgical training in the low-income regions of the world. Our data suggest that microsurgical training should be continuous and repetitive. Simulation training may benefit from models for repetitive training of relevant technical part-skills.

Case series have identified that de novo intracranial aneurysms occur. However, the risk for this occurrence has not been established. We examined the risk for the de novo intracranial aneurysm detection in a consecutive surgical case series. ⋯ There is a 10-year de novo aneurysm detection rate of between 10% and 16% after surgery. Smoking increases the risk of de novo aneurysm detection. Consideration needs to be given to surveillance angiography after aneurysm treatment.

To report a newly developed intraluminal triple-balloon shunt designed to preserve the blood flow of both the internal carotid artery (ICA) and the external carotid artery (ECA) during carotid endarterectomy in patients with a previous ipsilateral extracranial-intracranial bypass, in whom hemodynamic cerebral ischemia might be caused by cross-clamping at the ICA as well as the ECA. ⋯ This novel shunt device can be used safely and effectively in cases requiring preservation of the blood supply to both the ICA and the ECA during carotid endarterectomy.

A persistent primitive hypoglossal artery (PHA) is a rare congenital caroticobasilar anastomosis with a reported prevalence of 0.027%-0.26%. Intracranial aneurysms occur with a frequency of approximately 26% in the setting of PHAs. ⋯ We review the literature and discuss anatomic implications with respect to the extreme lateral infrajugular transcondylar exposure for clip ligation of a ruptured posterior inferior cerebellar artery aneurysm in the setting of a PHA.

In recent literature, there have been case reports of prenatal diagnosis of hemimegalencephaly, an extremely rare entity characterized by enlargement of all or portions of 1 cerebral hemisphere and intractable seizures. A unique case is presented of hemimegalencephaly of a fetus diagnosed in utero. ⋯ In utero diagnosis of complex developmental brain anomalies allows a multidisciplinary approach to provide optimal prenatal patient treatment and parental counseling.
