Minimally invasive alternatives to the pterional craniotomy include the minipterional and the supraorbital craniotomy (SOC). The latter is performed via either an eyebrow or an eyelid skin incision. The purpose of this systematic review was to analyze the type and the incidence of approach-related complications of these so-called "keyhole craniotomies". ⋯ Each of the 3 keyhole approaches has a specific set and incidence of approach-related complications. It is essential to be aware of these complications to make the safest individual choice.

Internal maxillary artery (IMA) bypass has gained momentum in the last 5 years for the treatment of complex cerebrovascular disorders and skull base tumors. However, some issues regarding this treatment modality have been proposed. As one of the most experienced neurosurgical teams to perform internal maxillary artery bypass in the world (>100 clinical cases), we reviewed the literature in aspects of basic anatomy of maxillary artery with its variations to the lateral pterygoid muscle, initial anastomosis modalities, and subsequent exposure techniques in cadaver studies, preoperative arterial evaluation methods, optimal interposed graft selections, and surgical outcome in the management of complex aneurysms, skull base tumors, and steno-occlusive disorders.

Percutaneous transforaminal endoscopic discectomy (PTED) is a minimally invasive surgical technique used principally for the treatment of lumbar disc herniation (LDH). LDH is a frequent spinal ailment in obese individuals. The aim of this prospectively designed study was to assess for the first time in the literature the impact of PTED in postoperative parameters of health-related quality of life (HRQoL) in obese patients with LDH within a 2-year follow-up period, to further evaluate the effectiveness of PTED. ⋯ PTED appears to be a generally safe and effective method for treating obese patients with LDH. However, major technical challenges that lead to a higher frequency of complications, as well as the lesser acquired clinical benefit, in obese patients may contribute to the further consideration for PTED in specific obese patients, especially on the grounds of low surgical experience.

There is a dearth of literature regarding management and outcomes of patients with a left ventricular assist device (LVAD) for advanced heart failure who develop intracranial hemorrhage (ICH). We conducted a case series from 2 centers highlighting patient outcomes and prognostic factors to help clinicians better understand and care for these high-risk patients. ⋯ Patients being treated with an LVAD who develop ICH have poor outcomes. Predictive factors for same-admission mortality are lower initial Glasgow Coma Scale score, presence of midline shift, and greater ICH volume.

The effectiveness and safety of LVIS stent-coiling is currently not known for treating tiny intracranial aneurysms. ⋯ Tiny cerebral aneurysms can be safely and effectively treated with appropriate endovascular approaches based on aneurysm specific morphology, especially neck size and neck-to-dome ratio.
