Is There a Risk of Stroke During Anterior Cervical Discectomy? A Randomized Controlled Trial.

Aim: To examine the effects of different retractor techniques for anterior cervical discectomy on cerebral oxygen saturation.

Material And Methods: In this study, a prospective comparative design was employed to examine the effects of different retractor techniques on a cohort of 48 adult patients with ASA I-II classification who underwent anterior cervical discectomy under general anesthesia. The study was conducted under assessor-blinded conditions, and the patients were divided equally into two groups: the self-retaining retractor group and the hand-held retractor group.

Posterior Quadratus Lumborum Block or Thoracolumbar Interfascial Plane Block and Postoperative Analgesia after Spinal Surgery: A Randomized Controlled Trial.

Introduction: The management of postoperative pain following lumbar disc herniation (LDH) surgery is crucial for the quality of recovery. The effectiveness of multimodal analgesia plans increases when interfascial plane blocks are included. This study sought to compare the analgesic efficacy of preoperative ultrasound-guided TLIP (thoracolumbar interfascial plane) blocks and posterior QLBs (quadratus lumborum blocks) in patients undergoing LDH surgery.

Effects of Cerebral Ischemia on Levels of Vascular Endothelial Growth Factor (VEGF) and Its Soluble Receptors: A Possible Link to Angiogenesis in Arteriovenous Malformations.

Aim: To investigate the levels of vascular endothelial growth factor (VEGF) in the brain, and its soluble forms, namely sVEGFR1 and sVEGFR2, levels in the plasma of rats after cerebral ischemia.

Material And Methods: Rats were divided into three groups as follows: Group 1: Sham-operated group, Group 2: Complete occlusion of the right carotid artery, Group 3: Complete occlusion of the right carotid artery and temporary occlusion of the left carotid artery for 10 min. Blood samples were collected on days 0 and 10 prior to the sacrification to measure the sVEGFR1 and sVEGFR2 levels.

Comparison of TachoComb and TissuDura in Terms of Adverse Effects and Complications in Duraplasty in Rats.

Aim: To compare two synthetic graft materials, TachoComb®, a fibrin sealant composed of collagen, fibrinogen, thrombin and aprotinin and TissuDura®, a collagen-based biomatrix.

Material And Methods: Thirty Sprague?Dawley rats were randomly divided into three groups with 10 animals in each group. A dural defect was created on the left parietal bone of each animal, and the dural defect was repaired using either TachoComb® (TachoComb group) or TissuDura® (TissuDura group).
