Medically intractable epilepsy involving drop attacks can be difficult to manage and negatively affect quality of life. Most studies investigating the effect of corpus callosotomy (CC) on seizures have been limited, focusing on the pediatric population or drop seizures alone, with little attention to other factors influencing seizure outcome. ⋯ CC for medically refractory generalizing epilepsy is effective for both drop seizures and other seizure types. CC should be considered soon after a patient has been deemed medically refractory because earlier age at surgery results in lower risk and better outcome.

The anterior choroidal artery (AChA) supplies important areas of the nervous system, particularly the posterior limb of the internal capsule and optic radiation. Treatment of AChA aneurysms poses particular challenges because of the complex anatomy of the aneurysm associated with the relatively small diameter of AChAs, making preservation of the parent vessel during clip ligation or endosaccular coiling challenging. ⋯ The ischemic complication rate from surgical treatment of AChA aneurysms is most closely associated with higher frequency of temporary clip applications for proximal control and may be lower than previously reported. Supplementary intraoperative tools and limitation of vessel manipulation should be used to improve outcomes.

Directional intraoperative Doppler (dioDoppler) ultrasonography is well established as a tool in the surgery of intracranial aneurysms and cerebral arteriovenous malformations. The literature provides little information about the possible usefulness of this method during surgery on cranial dural arteriovenous fistulas (dAVFs). ⋯ Reviewing our experience, we found that dioDoppler sonography is an easy, safe, effective, reliable, and instantaneous tool during surgery on cranial dAVFs.

Trigeminal neuralgia (TN) is relatively frequent in multiple sclerosis (MS) patients and can be extremely disabling. Surgical interventions are less effective for the treatment of MS-related TN compared with classic TN, and higher recurrence rates are observed. ⋯ Treatment failure occurs in most of the MS-related TN patients independently of the type of treatment. However, balloon compression had the highest rate of IPFR and PFI compared with other modalities in the initial treatment of MS-related TN.

During tumor removal in the endoscopic endonasal approach to pituitary adenomas with a significant suprasellar extension, the early descent of diaphragma sellae obscuring the visualization of the surgical field is a surgical challenge. ⋯ This technique was effective and practicable to elevate the diaphragma sellae during the tumor removal phase of transsphenoidal surgery. This simple self-retaining retractor may support the neurosurgeon's skill by providing control of the entire surgical field and adequate working space. It may also eliminate the risks of blind curettage during surgery.
