Long Tunneled External Ventricular Drains with Shunt Valves: A Technical Note.

Background: External ventricular drain (EVD) is a basic operation in neurosurgery. Due to the limitation of its safe duration, some patients need to receive multiple drainage operations. We describe the long tunneled EVD (LTEVD) with shunt valves that effectively avoid multiple operations as a technical note.

Canstatin represses glioma growth by inhibiting formation of VM-like structures.

Vasculogenic mimicry (VM) is different from classical tumor angiogenesis and does not depend on endothelial cells. VM is closely related to the prognosis of various cancers. Canstatin was first identified as an endogenous angiogenesis inhibitor.

A Keyhole Approach Centered by Anterior Squamous Suture to Hypertensive Basal Ganglia Hemorrhage.

Objective: This study aimed to improve the accuracy and efficacy of the keyhole transsylvian approach to remove hypertensive basal ganglia hemorrhage. The authors presented a stable keyhole craniotomy based on anterior squamous suture to expose insular cortex and basal ganglia.

Methods: Twenty-nine patients with hypertensive basal ganglia hemorrhage were treated with keyhole surgery and studied in Guangdong sanjiu brain hospital.

Outcome of Epidural Hematoma: Lessons from Solitary Fibrous Tumor/Hemangiopericytoma.

Background: Intracranial solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) is rare. In this report, a case of epidural hematoma (EDH) that eventually evolved into SFT/HPC is presented. We describe the possible association between the 2 diseases, which has not been previously reported.

Bronchogenic Cyst: Skull Base Lesions with Extracranial Extension.

Background: Intracranial bronchogenic cysts (BCs) are extremely rare. To our knowledge, this is the first report of a BC in which lesions involve the middle and posterior cranial fossa, as well as the infratemporal fossa.

Case Description: We present the case of a 38-year-old woman who suffered from a cranial nerve dysfunction for 2 years.
