The pre-operative embolization of hypervascular spinal tumors is often performed to decrease intraoperative blood loss and facilitate tumor resection; however, few studies have been published on its effectiveness in giant cell tumors (GCT) of the sacrum and spine. The purpose of the present study was to investigate the value of surgical excision with pre-operative transarterial embolization for...

BACKGROUND Intraoperative transfusion decisions generally are guided by blood loss estimation and periodic invasive hemoglobin measurement. Continuous hemoglobin measurement by pulse cooximetry (pulse hemoglobin; Rainbow® SET Pulse CO-Oximeter, Masimo Corporation, Irvine, CA) has good agreement with laboratory hemoglobin in healthy volunteers and could aid transfusion decision-making. Because i...

VISUAL loss after nonocular surgery is a rare but devastating perioperative complication. It has been documented in a wide variety of procedures, the most common of which are cardiopulmonary bypass, head and neck operations, and prone spine operations. Ischemic optic neuropathy is the most common diagnosis in these cases. Factors believed to be associated with its occurrence are large intraoper...

BACKGROUND Breast reduction surgery is a common cosmetic surgery with a high incidence of blood loss and transfusion. In this surgery, the reduction of blood loss related to surgical manipulation and the volume of resected tissue is a target. In the present study, we compared the effects of esmolol-induced controlled hypotension on surgical visibility, surgical bleeding, and the duration of sur...

Introduction: In recent years, the surgical management of angiofibroma has been greatly influenced by the use of endoscopic techniques. However, large tumors that extend into difficult anatomic sites present major challenges for management by either endoscopy or an open-surgery approach which needs new technique for the complete en block resection.   Materials and Methods: In a prospective obse...

BACKGROUND AND PURPOSE Juvenile angiofibromas are hypervascular tumors that may benefit from preoperative devascularization to reduce intraoperative blood loss. Our purpose was to evaluate the extent of angiographic devascularization and intraoperative blood loss by using only Onyx for percutaneous juvenile angiofibroma tumor embolization. MATERIALS AND METHODS We reviewed the clinical record...

STATEMENT OF THE PROBLEM The preoperative or intraoperative administration of intravenous magnesium sulfate has been approved as an accepted medication for stabilizing hemodynamic indices during surgeries. PURPOSE Intraoperative blood loss during orthognathic surgery is frequently abundant and sometimes requires blood transfusion. The present trial addressed the efficacy of intravenous magnes...

BACKGROUND Opium is an addictive agent and one of the most common narcotics With great challenges of intraoperative hemodynamic instabilities. OBJECTIVES The current study aimed to assess the effects of clonidine on intraoperative blood loss in patients with and without opium addiction in femoral fracture surgeries. PATIENTS AND METHODS In a randomized clinical trial, 160 candidates for ele...

Intraoperative blood loss is frequently an overarching concern during total hip arthroplasty (THA) for patients who have ankylosing spondylitis with hip involvement. However, the factors that affect blood loss have not been identified. The goal of this study was to investigate these factors among patients with ankylosing spondylitis. Patients in the authors' department who had ankylosing spondy...
