Recurrence of a Totally Excised Cavernous Venous Malformation 25 Years Later

, 2021
Recurrence of cavernous venous malformation is exceedingly rare. In 1995, a 16-year-old woman was referred for left axial proptosis. Her left visual acuity was 20/200, and there were choroidal folds in the OS.

Transcondylar Approach for Resection of Lateral Medullary Cavernous Malformation.

, 2017
BACKGROUND: Resection of a medullary cavernous malformation requires aggressive exposure, but there is controversy on how much occipital condyle can be safely removed during the transcondylar approach.

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Analysis of lining force transmission coefficient and surrounding rock displacement in lined rock caverns for underground gas storage

Deep Underground Science and Engineering, EarlyView.
This study derives an explicit expression for the lining force transmission coefficient of underground gas storage lined rock caverns (LRCs) via the complex variable function method, considering the displacement release coefficient. Taking the 1‰ tensile strain of surrounding rock as the criterion to determine lining thickness, it systematically ...

Transoral endoscopic surgical approach to venous malformation of the parapharyngeal space

SAGE Open Medical Case Reports, 2020
We encountered a rare case of venous malformation located in the parapharyngeal space. The 65-year-old female patient did not have any symptoms, and the malformation was discovered incidentally during a clinical survey.
