BACKGROUND: Renin angiotensin antagonists (RAAs) may block protective vasopressor responses during surgery. Evidence linking RAAs with intraoperative hypotension and perioperative adverse events is conflicting. METHODS: Retrospective case-control study of 258 consecutive patients who underwent elective total knee or hip replacement between January 1(st) 2013 and August 31(st) 2016, and who were chronically prescribed a single blood pressure lowering agent up to the time of surgery...

Surgical resection is the current standard of therapy for the treatment of arteriovenous malformation (AVM). Endovascular embolization is commonly used as an adjunct prior to surgical resection because it is believed to reduce the risk of intraoperative bleeding. Embolization has been associated with other complications including visual deficits, vessel perforation, and catheter adhesion. Catheter adhesion in which retained segments are contained within the embolization cast are not necessarily cause for concern, but retention of larger portions may confer an increased risk of thrombus formation...

BACKGROUND: Antiplatelet medications are usually discontinued before elective neurosurgery, but this is not an option for emergent neurosurgery. We performed a retrospective cohort study to examine whether preoperative aspirin use was associated with worse outcomes after emergency neurosurgery in elderly patients. METHODS: We analyzed all cases of emergency neurosurgical procedures for traumatic intracranial hemorrhage from 2008 to 2012 at a level 1 trauma center...

OBJECTIVE Fusion surgery with instrumentation is a widely accepted treatment for cervical spine pathologies. The authors propose a novel technique for subaxial cervical fusion surgery using paravertebral foramen screws (PVFS). The authors consider that PVFS have equal or greater biomechanical strength than lateral mass screws (LMS). The authors' goals of this study were to conduct a biomechanical study of PVFS, to investigate the suitability of PVFS as salvage fixation for failed LMS, and to describe this novel technique...

Irreversible electroporation (IRE) is a nonthermal ablation modality employed to induce in situ tissue-cell death. This study sought to evaluate the efficacy of a novel high-frequency IRE (H-FIRE) system to perform hepatic ablations across, or adjacent to, critical vascular and biliary structures. Using ultrasound guidance H-FIRE electrodes were placed across, or adjacent to, portal pedicels, hepatic veins, or the gall bladder in a porcine model. H-FIRE pulses were delivered (2250 V, 2-5-2 pulse configuration) in the absence of cardiac synchronization or intraoperative paralytics...

INTRODUCTION: Carbon dioxide is the standard insufflation gas for laparoscopy. However, in many areas of the world, bottled carbon dioxide is not available. Laparoscopy offers advantages over open surgery and has been practiced using filtered room air insufflation since 2006 at Bongolo Hospital in Gabon, Africa. OBJECTIVE: Our primary goal was to evaluate the safety of room air insufflation related to intraoperative and postoperative complications. Our secondary aim was to review the types of cases performed laparoscopically at our institution...

OBJECTIVES: Cardiac arrest (CA) in patients with acute myocardial infarction is associated with a poor prognosis. Due to the additional trauma, risk of stroke and lack of data, coronary artery bypass grafting (CABG) is a controversial revascularization strategy for patients who cannot be treated percutaneously. Against this background, we investigated the outcome of patients from our department with acute myocardial infarction undergoing CABG after CA. METHODS: Between January 2001 and January 2015, 129 patients with preoperative CA due to acute myocardial infarction underwent CABG at our institution within 48 h after the CA had occurred...

BACKGROUND: Uterovaginal prolapse in very elderly women is a growing problem due to increased life expectancy. Surgeons and anaesthetists may be wary of performing quality of life surgery on this higher risk group. Where surgery is undertaken, it is commonly performed vaginally; there is a perception that this is better tolerated than abdominal surgery. Little data is published about laparoscopic prolapse surgery tolerability in this population, and laparoscopic surgery is perceived within the urogynaecological community as complex and lengthy and hence inherently unsuitable for the very elderly...

OBJECTIVE Hypoalbuminemia is known to be independently associated with postoperative acute kidney injury (AKI). However, little is known about the association between the preoperative serum albumin level and postoperative AKI in patients undergoing brain tumor surgery. The authors investigated the incidence of AKI, impact of preoperative serum albumin level on postoperative AKI, and death in patients undergoing brain tumor surgery. METHODS The authors retrospectively reviewed the electronic medical records and laboratory results of 2363 patients who underwent brain tumor surgery between January 2008 and December 2014...

Every surgical problem that increases the likelihood of intraoperative and postoperative complications is considered to be a difficult surgical situation. Based on this definition, Korenkov et al. proposed to classify patients according to the following intraoperative difficulty levels (I to IV): (I) ideal situation (easy to operate, no problems), (II) fairly easy/manageable/simple (some minor difficulties may occur), (III) difficult/problematic (difficult to operate; some operative techniques are considerably more difficult than others), and (IV) very difficult (every operative step is difficult/challenging)...

INTRODUCTION: The thoracolumbar fascia has been well studied and is known to have crisscrossing fibers. Based on surgical experience, we have hypothesized that the decussating fibers of this fascia may indicate a specific vertebral level. Therefore, the following anatomical study was performed. METHODS: Twenty adult fresh frozen cadavers aged 72-84 years old at death were placed in the prone position and the skin of the lumbar and upper sacrum was removed. Careful attention was given to the thoracolumbar fascia and any fibers of it that grossly crossed the midline to inderdigitate with its contralateral counterpart...

BACKGROUND: Injury is the leading cause of death in children under 18 years. Damage control principles have been extensively studied in adults but remain relatively unstudied in children. Our primary study objective was to evaluate the use of damage control laparotomy (DCL) in critically injured children. METHODS: An American College of Surgeons-verified Level 1 trauma center review (1996-2013) of pediatric trauma laparotomies was undertaken. Exclusion criteria included: age older than 18 years, laparotomy for abdominal compartment syndrome or delayed longer than 2 hours after admission...
