Gamma Knife Radiosurgery for Spetzler-Martin Grade III Brain Arteriovenous Malformations.

Background: Spetzler-Martin (SM) grade III arteriovenous malformations (AVMs) show angioarchitecture heterogeneity and lack a clearly defined treatment strategy. This study aims to evaluate outcomes after treatment of SM grade III AVMs with Gamma Knife radiosurgery (GKRS).

Methods: A single-institution retrospective analysis was conducted of 307 patients with SM grade III AVMs undergoing GKRS between October 2006 and December 2020 with follow-up times of at least 24 months.

Reconstruction of Large Anterior Skull Base Defects After Resection of Sinonasal Tumors With Intracranial Extension by Using Pedicled Double Flap Techniques.

Introduction: The use of surgical resection for large anterior skull base (ASB) tumors and sinonasal malignancies with intracranial extension will result in a large skull base defect. Reconstruction of large ASB defects using traditional techniques is high risk and may lead to postoperative cerebral spinal fluid (CSF) leakage, meningitis, and an increase in mortality rate. The use of a pedicled double flap technique to reconstruct the ASB defect may decrease complications.

Gamma Knife Radiosurgery for Brain Arteriovenous Malformations: A 15-Year Single-Center Experience in Southern Vietnam.

Background: In the present study, we aimed to identify the obliteration outcomes, complications, and predictors in gamma knife radiosurgery (GKRS) treatment of brain arteriovenous malformations (AVMs) at a tertiary center in a developing country in a 15-year experience.

Methods: We retrospectively reviewed the clinical data and GKRS procedures of patients who had undergone GKRS from 2006 to 2011 (cohort 1) and from 2011 to 2020 (cohort 2) at Cho Ray Hospital, Vietnam. The exclusion criteria included patients with <24 months of follow-up without obliteration or AVM-related hemorrhage during the study period.

Apathy in a high prevalence population of moderate to severe traumatic brain injury: An investigation in Vietnam.

Objective: The reduction of goal-directed behavior, termed apathy, is a pervasive and debilitating syndrome after traumatic brain injury (TBI). However, understanding of apathy as a multifaceted construct is limited, especially in Southeast Asian nations. This study aimed to investigate the severity, insight, and psychosocial influences of apathy in executive, emotional, and initiation dimensions in Vietnam-a country with high prevalence of TBI.

Surgical anatomy of the ophthalmic artery: its origin and proximal course.

Objective: We examined the surgical anatomy of the ophthalmic artery (OA) by dissection of cadaver heads, evaluating the anatomic relationships between the origin of the OA and both its proximal course and surrounding structures. In addition, we demonstrated the surgical application of these anatomic features for safe surgical exploration of this region.

Methods: Through anatomic dissection, the origin of the OA was examined in both sides of 25 formalin-fixed and 10 fresh cadaver specimens.
