Middle Meningeal Arterial Embolization Combined With Drilling in the Treatment of Acute Epidural Hematoma.

Objective: The purpose of this study was to determine the technical feasibility and safety of middle meningeal arterial (MMA) embolization combined with drilling drainage in the treatment of acute epidural hematoma (AEDH) by comparing it with traditional craniotomy in the treatment.

Methods: One hundred seventeen patients with AEDH treated for MMA embolization combined with drilling and drainage or craniotomy hematoma removal from January 2017 to September 2020 were retrospectively analyzed and divided into a craniotomy group (n=85) and a minimally invasive group (n=32). Hematoma removal was performed in the craniotomy group, and MMA embolization combined with drilling and drainage was performed in the minimally invasive group.

Mitigation of acute radiation-induced brain injury in a mouse model using anlotinib.

Background: With the development of radiological technologies, radiotherapy has been gradually widely used in the clinic to intracranial tumours and become standardised. However, the related central nervous system disorders are still the most obvious complications after radiotherapy. This study aims to quantify the effectiveness of anlotinib, a small molecule inhibitor of multiple receptor tyrosine kinases, in mitigating acute phase of radiation-induced brain injury (RBI) in a mouse model.

Application of Absolute Alcohol in the Treatment of Traumatic Intracranial Hemorrhage via Interventional Embolization of Middle Meningeal Artery.

Traumatic brain injury is a common condition in neurosurgery. Traditional methods of treatment include conservative treatment and surgical evacuation using burr-holes or craniotomy; however, studies have reported problems such as high re-expansion rates after conservative treatment of epidural hematoma and high postoperative recurrence rates of subdural hematoma. Solutions to these problems are lacking, and research into new treatment methods is ongoing.

Feasibility Study of the Low-Cost Motion Tracking System for Assessing Endoscope Holding Skills.

Background: The ability to hold an endoscope is an important skill for surgeons and assistants performing endoscopic neurosurgery. Motion tracking can provide an objective assessment for surgical skills and may aid in endoscopic neurosurgery. We developed a cost-effective system to study the feasibility of objectively distinguishing performance levels for operating an endoscope.

Risk factors for the development of chronic subdural hematoma in patients with subdural hygroma.

Objective: Patients with subdural hygroma (SDG) are at increased risk of developing chronic subdural hematoma (CSDH). However, the factors that increase the risk of conversion are not fully understood. This study was to assess the risk factors of SDG conversion to CSDH.

Recurrent Bilateral Chronic Subdural Hematoma After Interventional Embolization Combined With Drilling and Drainage Treatment.

The main treatment for chronic subdural hematoma (CSDH) is surgical drilling and drainage. Meanwhile, the most accepted treatment strategy for bilateral CSDHs (bCSDHs) is unilateral evacuation only on the larger or symptomatic side because the contralateral hematoma is generally either small or asymptomatic. However, the probability of recurrence is high.

1,n-Rearrangement of allylic alcohols promoted by hot water: application to the synthesis of navenone B, a polyene natural product.

It was reported for the first time that hot water as a mildly acidic catalyst efficiently promoted 1,n-rearrangement (n = 3, 5, 7, 9) of allylic alcohols. In some cases, the rearrangement reactions joined isolated C-C double or triple bonds to generate conjugated polyene or enyne structure motifs. We used the 1,3-rearrangement reaction of an allylic alcohol in hot water as part of an attractive new strategy for construction of the polyene natural product navenone B by iterative use of a Grignard reaction, a 1,3-rearrangement of the resulting allylic alcohol, and subsequent oxidation of the rearranged product.
