History has taught us that Mexican culture has been largely supported by women, despite gender prejudice from the society. Neurosurgery has not been the exception. Therefore, we investigated the challenges and influence of female neurosurgeons in Mexico. ⋯ Although a steady increase has occurred of women in neurosurgery in Mexico, there is still work to do, especially to overcome the barriers related to the old assumptions of the cultural and social roles of women.

Comparative Study
Posterior lumbar interbody fusion versus transforaminal lumbar interbody fusion: Finite element analysis of the vibration characteristics of fused lumbar spine.
Previous studies have investigated biomechanical characteristics of the lumbar spine after different types of lumbar interbody fusion surgery under static loadings. However, very few have dealt with the whole-body vibration (WBV) condition that is typically present in vehicles. The aim of this study was to compare the influence of posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) on dynamic responses of the fused lumbar spine to vertical WBV. ⋯ This study may be helpful to quantify dynamic mechanical properties of the fused lumbar spine, and better understand biomechanical differences between the PLIF and TLIF procedures during vibration.

Persistent trigeminal artery (PTA) is the most common persistent carotid-basilar fetal anastomosis and terminates extremely rarely directly in the dominant hemispheric branch of the anterior inferior cerebellar artery (AICA). We present a case of a branch of this PTA variant (Saltzman type 3b) demonstrated as the feeding artery of a large posterior petrous meningioma, which was confirmed under direct vision during surgery through the extended retrosigmoid approach. ⋯ Meningioma in the posterior cranial fossa may recruit substantial supply from branches of the PTA terminating in the AICA. This PTA variant should be recognized during surgical resection of posterior fossa neoplasms to prevent ischemic complication of the AICA territory.

To investigate the effect of superficial temporal artery-posterior cerebral artery (STA-PCA) bypass on chronic basilar artery occlusion (CBAO). ⋯ STA-PCA bypass can improve cerebral blood flow perfusion in CBAO patients. The diameter and flow of the superficial temporal artery can be increased to meet the demand of blood supply.

Biography Historical Article
Dr. Thanjavur Santhanakrishna Kanaka-A Pioneer and Neurosurgical Innovator.
Thanjavur Santhanakrishna Kanaka, M.B.B.S., M.S. (General Surgery), M.S. (Neurosurgery), Ph.D., and former Captain, Indian Army Medical Corps, was born on March 31, 1932. She became the first woman neurosurgeon in India and all of Asia. ⋯ Through her innovative thinking, compassion for her patients, and unwavering resilience, Dr. Kanaka has continued to serve as an inspiration to all pursuing a career in academic medicine and neurosurgery.
