BACKGROUND: Temporary arterial occlusion (TAO) is a valuable tool for minimizing intraoperative rupture risk during intracranial aneurysm microsurgery; however, it may also be associated with ischemic injury. OBJECTIVE: This study aims to identify surgical and intraoperative neurophysiological monitoring (IONM) factors that predict perioperative stroke risk after TAO. METHODS: We performed a retrospective chart review of 177 intracranial aneurysm surgeries at our institution, in which TAO was performed before the placement of a permanent clip under monitoring with somatosensory evoked potentials (SSEPs) and electroencephalography (EEG)...

INTRODUCTION: Microsurgical techniques are essential in plastic surgery; however, inconsistent training practices, acquiring these skills can be difficult. To address this, we designed a standardised laboratory-based microsurgical training programme, which allows trainees to develop their dexterity, visuospatial ability, operative flow and judgement as separate components. METHOD: Thirty trainees completed an initial microsurgical anastomosis on a chicken femoral artery, assessed using the structured assessment of microsurgical skills (SAMS) method...

OBJECTIVE The management of vestibular schwannoma (VS) remains controversial. One commonly cited advantage of microsurgery over other treatment modalities is that tumor removal provides the greatest chance of long-term cure. However, there are very few publications with long-term follow-up to support this assertion. The purpose of the current study is to report the very long-term risk of recurrence among a large historical cohort of patients who underwent microsurgical resection. METHODS The authors retrospectively reviewed the medical records of patients who had undergone primary microsurgical resection of unilateral VS via a retrosigmoid approach performed by a single neurosurgeon-neurotologist team between January 1980 and December 1999...

The purposes of this study were to review historical changes in the classification of spinal arteriovenous (AV) shunts and to propose a practical classification system. The associated literature regarding the classification of spinal AV shunts was reviewed in the angiography era between 1967 and 2015. The classification systems of spinal AV shunts and a proposed classification system were presented with neuroradiological imaging and medical illustrations. There have been seven major classification systems based on the evolution of diagnostic methods as well as treatments for spinal AV shunts: the first description of spinal AV shunts diagnosed and classified using spinal angiography in 1971; the second classification based on a case report of intradural direct perimedullary arteriovenous fistulas (AVFs) treated by microsurgery in 1987; the third classification based on a case series of intradural perimedullary AVFs treated by endovascular interventions in 1993; the fourth and fifth classification systems based on a case series of spinal AVFs and arteriovenous malformations (AVMs) treated by microsurgery or endovascular interventions in 2002; the sixth classification based on a case series of cranio-spinal dural AV shunts in 2009; and the seventh classification based on a case series of extradural AVFs treated by microsurgery and endovascular interventions in 2011...

INTRODUCTION: Use of Descemet Membrane Endothelial Keratoplasty (DMEK) has been limited because of problems with donor preparation, i.e. tearing of the Descemet membrane and difficulties in unfolding the Endothelium-Descemet-Membrane-Layer (EDML) in the anterior chamber (AC). The purpose of this work was to describe a novel approach to teaching anatomy-based donor and recipient preparation in a DMEK-Wetlab. MATERIAL AND METHODS: We teach successful mono-manual donor preparation of human corneas in organ culture not suitable for transplantation, including peripheral markers for orientation...

REVIEW
Daniel Owen Young, Anjali S Kumar
Local excision (LE) of early-stage rectal cancer avoids the morbidity associated with radical surgery but has historically been associated with inferior oncologic outcomes. Newer techniques, including transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS), have been developed to improve the quality of LE and extend the benefits of LE to tumors in the more proximal rectum. This article provides an overview of conventional LE, TEM, and TAMIS techniques, including indications for their use and pertinent literature on their associated outcomes for rectal cancer...

A serious complication of chronic hepatic insufficiency is acute-on-chronic liver failure, a recognized syndrome characterized by acute decompensation of cirrhosis and organ/system failure. We investigated the use of adipose-derived mesenchymal stem cells (AD-MSCs) in an experimental model of acute-on-chronic liver failure, developed by microsurgical extrahepatic cholestasis in rats. Rats undergoing microsurgical extrahepatic cholestasis were treated by intraparenchymal liver injection of human or rat AD-MSCs, undifferentiated or previously differentiated in vitro toward the hepatocyte lineage...

REVIEW
Kenichi Nishiyama
An exoscope, high-definition video telescope operating monitor system to perform microsurgery has recently been proposed an alternative to the operating microscope. It enables surgeons to complete the operation assistance by visualizing magnified images on a display. The strong points of exoscope are the wide field of view and deep focus. It minimized the need for repositioning and refocusing during the procedure. On the other hand, limitation of magnifying object was an emphasizing weak point. The procedures are performed under 2D motion images with a visual perception through dynamic cue and stereoscopically viewing corresponding to the motion parallax...

BACKGROUND: Journal ranking based on the impact factor (IF) can be distorted by self-citation. The aim of this study is to investigate the present status of self-citation in the plastic surgery journals and its effect on the journals' IFs. METHODS: IF, IF without self-citations (corrected IF), self-cited rate, and self-citing rate for 11 plastic surgery journals were investigated from 2009-2015, by reviewing the Journal Citation Report(®). The correlations of the IF with the self-cited rate and the self-citing rate were statistically assessed...

In patients without systemic manifestations of tuberculosis, isolated brainstem tuberculous abscesses are infrequently observed. The present study reports a rare case of two cystic tuberculous abscesses involving the dorsal aspect of the medulla oblongata in an otherwise healthy 14-year-old Chinese girl, whose primary complaint was respiratory distress. These lesions were successfully treated using a microsurgical excision approach and anti-tuberculosis therapy. Although rare, tuberculous abscesses should be considered in the differential diagnosis of isolated cystic brainstem lesions...

BACKGROUND: Although all microsurgeries are based on the use of surgical microscopes, several alternative magnification systems have shown promising results. Improvements in image quality facilitated the use of video systems in microsurgeries with safety and accuracy. The aim of this study was to evaluate the use of a low-cost, video-assisted magnification system in peripheral neurorrhaphy in rats. METHODS: Twenty Wistar rats were randomly divided into 2 matched groups according to the magnification system used: the microscope group, with neurorrhaphy performed under a microscope with an image magnification of 40×; and the video system group, with the procedures performed under a video system composed of a high-definition Sony camcorder DCR-SR42 set to 52× magnification, macro lenses, 42-inch television, and a digital HDMI cable...
