Direct Superficial Temporal Artery-Proximal Middle Bypass in Moyamoya Disease: Predicting Postoperative Symptomatic Contralateral Stroke Using Clinical Characteristics and Angiographic Collateralization Patterns.

Background: Moyamoya disease (MMD) is a rare cerebrovascular disorder marked by internal carotid artery narrowing, collateral neovascularization, and symptomatic cerebral ischemia. Select patients can benefit from direct bypass (superficial temporal artery [STA]-proximal middle [MCA] bypass) by restoring blood flow to hypoperfused territories. Symptomatic contralateral stroke (CS) following STA-MCA bypass is a devastating, poorly understood complication.

Duplex Ultrasound Screening for Deep Venous Thrombosis in Patients Undergoing Craniotomy for Intracranial Tumors: A Single Institutional Series.

Objective: The frequency of duplex ultrasound screening (DUS) for deep vein thrombosis (DVT) in patients with brain tumors undergoing craniotomy is center-specific. We evaluated clinical conditions that increase the tendency to perform DUS, focusing on tumor type.

Methods: This is a single-center retrospective analysis to assess the association of intracranial tumor type with DVT as a major decision-making indicator for DUS.

Intraoperative mechanical power and postoperative pulmonary complications in low-risk surgical patients: a prospective observational cohort study.

Background: Inadequate intraoperative mechanical ventilation (MV) can lead to ventilator-induced lung injury and increased risk for postoperative pulmonary complications (PPCs). Mechanical power (MP) was shown to be a valuable indicator for MV outcomes in critical care patients. The aim of this study is to assess the association between intraoperative MP in low-risk surgical patients undergoing general anesthesia and PPCs.

Perioperative Autonomic Dysfunction in a Patient With Charcot-Marie-Tooth Disease: A Case Report.

Autonomic dysfunction can lead to unexpected hemodynamic instability during surgery, and best practices for the perioperative care of patients with this condition are not well-defined. We report the case of a 63-year-old woman with Charcot-Marie-Tooth disease who experienced perioperative autonomic dysfunction characterized by severe fluctuations in blood pressure while under spinal anesthesia. However, <1 month later, a second hip surgery performed under general anesthesia with special precautions resulted in an uncomplicated perioperative course, with only mild fluctuations in blood pressure.

Respiratory Adverse Events After LMA® Mask Removal in Children: A Randomized Trial Comparing Propofol to Sevoflurane.

Background: The removal of the laryngeal mask airway (LMA®) in children may be associated with respiratory adverse events. The rate of occurrence of these adverse events may be influenced by the type of anesthesia. Studies comparing total intravenous anesthesia (TIVA) with propofol and sevoflurane are limited with conflicting data whether propofol is associated with a lower incidence of respiratory events upon removal of LMA as compared to induction and maintenance with sevoflurane.

Management of a mechanical aortic valve during left ventricular assist device implantation in a previously replaced aortic root.

The use of left ventricular assist device (LVAD) in patients with mechanical aortic valves may result in thromboembolic events due to blood stasis around the valve and intermittent valve opening. Mechanical aortic valves encountered during LVAD implantation are managed by replacement with a tissue valve, or closure of the valve with a patch. Closure of the valve carries the risk of sudden death in cases of LVAD stoppage.

Low Pressure Robot-assisted Radical Prostatectomy With the AirSeal System at OLV Hospital: Results From a Prospective Study.

Background: Limited studies examined effects of pneumoperiotneum during robot-assisted radical prostatectomy (RARP) and with AirSeal. The aim of this study was to assess the effect on hemodynamics of a lower pressure pneumoperitoneum (8 mmHg) with AirSeal, during RARP in steep Trendelenburg 45° (ST).

Materials And Methods: This is an institutional review board-approved, prospective, interventional, single-center study including patients treated with RARP at OLV Hospital by one extremely experienced surgeon (July 2015-February 2016).

Two heterozygous mutations in NFATC1 in a patient with Tricuspid Atresia.

Tricuspid Atresia (TA) is a rare form of congenital heart disease (CHD) with usually poor prognosis in humans. It presents as a complete absence of the right atrio-ventricular connection secured normally by the tricuspid valve. Defects in the tricuspid valve are so far not associated with any genetic locus, although mutations in numerous genes were linked to multiple forms of congenital heart disease.
