INTRODUCTION: Pyoderma gangrenosum (PG) is a rare type of autoimmune disease that results in progressive ulcers with or without previous trauma. However, PG is not well understood to date, and its treatment therefore remains a challenge. Because of the disease's systemic characteristic and the unpredictability of the clinical course, no gold standard treatment is available, especially concerning the surgical procedures to treat pyodermic lesions. Often, PG is not recognized during routine clinical practice, and standard ulcer treatment (conservative wound care, debridement, skin grafting, and local flap coverage) is initiated; this induces an autoinflammatory response, resulting in disastrous ulcers, thereby making free flap coverage necessary...

The ideal scalp reconstruction involves closure of the defect with similar hair-bearing local tissue in a single step. Various reconstructions can be used including primary closure, secondary healing, skin grafts, local flaps, and microvascular tissue transfer. A 53-year-old female patient suffered glioblastoma, which had recurred for the second time. The neurosurgeons performed radial debridement and an additional resection of the tumor, followed by reconstruction using a serratus anterior muscle flap with a split-thickness skin graft...

BACKGROUND: There is still no clear guideline for surgical treatment for patients with medically refractory trigeminal neuralgia (TN). When it comes to which surgical treatment to choose, microvascular decompression (MVD) or Gamma Knife surgery (GKS), we should know the long-term outcome of each treatment. METHODS: We analyzed 179 patients undergoing MVD and 52 patients undergoing GKS followed for 1 year or longer. We evaluated the patient's neurological status including pain relief, complications and recurrence...

Little literature is available on hemiparesis caused by vascular medullary compression, which may occur as a result of dolichoectasia of the vertebrobasilar arterial system. In this paper, we report a case of vertebral artery compression of the medulla oblongata in a 67-year old woman. The patient was hypertensive and developed hemiparesis and intermittent spasms for five years, which became worsened for one year. Cranial nerve MRI showed compression of the medulla oblongata by the left vertebral artery. Motor evoked potential (MEP) examination showed abnormal conduction of MEPs of bilateral toe abductors...

BACKGROUND: Invasive tests measuring resistance to cerebral spinal fluid (CSF) outflow and the effect of temporary drainage of CSF are used to select candidates affected by idiopathic normal pressure hydrocephalus (iNPH) for shunt surgery. Neither test, however, completely excludes patients from treatment. Perfusion and diffusion magnetic resonance imaging (MRI) are non-invasive techniques that might be of value in selecting patients for surgical treatment and understanding brain changes in iNPH patients...

BACKGROUND: Metabolic syndrome (MetS) is associated with an increased risk of cerebrovascular diseases, including cerebral ischemia. Microvascular dysfunction is an important feature underlying the pathophysiology of cerebrovascular diseases. In this study, we aimed to investigate the impacts of ischemia and reperfusion (IR) injury on the cerebral microvascular function of rats with high-fat diet-induced MetS. RESULTS: We examined Wistar rats fed a high-fat diet (HFD) or normal diet (CTL) for 20 weeks underwent 30 min of bilateral carotid artery occlusion followed by 1 h of reperfusion (IR) or sham surgery...

BACKGROUND: Microvascular decompression (MVD) is the most useful treatment for hemifacial spasm (HFS). During MVD surgery, abnormal muscle response (AMR) is widely used. ZL response (ZLR) is a new monitoring method for HFS. We compared the effect of AMR plus ZLR and simple AMR. METHODS: We performed a retrospective study of 1,868 cases of HFS treated using intraoperative monitoring between January 2013 and December 2015. Among the 1,868 cases, 896 patients underwent simple AMR monitoring and 972 underwent combined intraoperative monitoring of AMR and ZLR...

BACKGROUND: Microvascular invasion (mvi) is an important risk factor for recurrent hepatocellular carcinoma (HCC), even after curative liver resection or orthotopic liver transplantation. However, mvi is difficult to detect preoperatively. The aim of this study was to clarify the risk factors of postoperative recurrence and investigate predictive factors of mvi before hepatectomy for HCC classified within the Milan criteria. METHODS: One hundred fifty-nine patients with hepatocellular carcinoma (HCC) classified within the Milan criteria, who underwent hepatectomy, were enrolled in this study...

BACKGROUND & AIMS: Microvascular invasion (mVI) is a major prognostic factor in hepatocellular carcinoma (HCC) that cannot be detected before surgery. Predictive biomarkers of mVI are thus urgently needed. We have developed an original approach of virtual biopsy to assess the performance of an immunohistochemical panel comprising three biomarkers of mVI (H4K16ac, H4K20me2, PIVKA-II) for the prediction of mVI in HCC core needle biopsies (CNB). METHODS: A test set of HCC surgical specimens (n=64) and an independent validation set of HCC CNB (n=42) were constituted...

OBJECT: Learning to perform microvascular anastomosis is difficult. Laboratory practice models using artificial vessels are frequently used for this purpose. However, the efficacy of such practice models has not been objectively assessed on the performance of microvascular anastomosis during live surgical settings. This study was carried out to assess the transfer of learning from practicing microvascular anastomosis on tubes to anastomosing rat's abdominal aorta. METHODS: Ten surgeons without any experience in microvascular anastomosis were randomly assigned to an experimental or a control group...

OBJECTIVE: Though it is usually successful, failure or delayed pain recurrence may occur after gamma knife surgery (GKS) in patients with trigeminal neuralgia (TN), and additional intervention may be required. This study aimed to investigate whether the safety and efficacy of microvascular decompression (MVD) were influenced by prior GKS. PATIENTS AND METHODS: The authors retrospectively evaluated 36 consecutive TN patients who underwent MVD after failed GKS from January 2012 to June 2013...

Nervus intermedius neuralgia is one of the craniofacial neuralgias, which is extremely rare compared with trigeminal or glossopharyngeal neuralgia. Despite its unique symptom, the aetiology remains unclear. We present a case of a surgically treated 36-year-old woman who suffered from paroxysmal stabbing deep-ear pain for over 10 years. Preoperative magnetic resonance imaging demonstrated a vascular loop compressing the root entry zone of the vestibulocochlear nerve between the seventh and eighth cranial nerves, suggesting nervus intermedius neuralgia as a cause of her pain...

OBJECTIVE: We have demonstrated that angiogenesis in acellular nerve allografts (ANAs) can promote neuroregeneration. The present study aimed to investigate the microvascular regeneration pattern of ANAs in Sprague-Dawley (SD) rats. METHODS: Sixty male SD rats were randomly divided into an autologous group and a rat acellular nerve allograft group (rANA), and 10-mm sciatic nerve defects were induced in these rats. On the 7th, 14th and 21st days after surgery, systemic perfusion with Evans Blue (EB) or lead oxide was performed on the rats through carotid intubation...

BACKGROUND: Induction of anaesthesia causes significant macrohaemodynamic changes, but little is known about its effects on the microcirculation. However, alterations in microvascular perfusion are known to be associated with impaired tissue oxygenation and organ dysfunction. Microvascular reactivity can be assessed with vascular occlusion testing, which evaluates the response of tissue oxygen saturation to transient ischaemia and reperfusion. OBJECTIVE: The aim of the current study was to evaluate the effects of an opioid-based anaesthesia induction on microvascular reactivity...

In most hemifacial spasm cases, the spasm initiates from the orbicularis occuli muscle and gradually spreads downwards to the orbicularis oris and buccinator muscles. Seldomly, the spasm might start from the orbicularis oris and buccinator muscles and develop upwards, which has been called as atypical hemifacial spasm (aHFS). Until now, little is known about its pathogenesis and the efficacy of microvascular decompression (MVD) surgery. We reviewed 1935 HFS cases undergoing MVD between 2007 through 2016. Among them, 15 were diagnosed as aHFS, whom were focused on...

Microsurgery simulation courses increasingly use assessment methodologies to evaluate the quality of microvascular anastomosis and to provide constructive feedback in competency-based training. Assessment tools evaluating the "journey" of skill acquisition in anastomosis have evolved, including global rating scores, hand motion analysis, and evaluation of the final outcome, that is, "end-product" assessment. Anastomotic patency is the gold standard end-product in clinical microvascular surgery, and in vivo end-to-side anastomosis, which can be confirmed using the Acland-test...

OBJECTIVE: While not life threatening, hemifacial spasm (HFS) can be disabling and significantly affect quality of life (QOL). The aim of the study was to assess the major factors affecting the QOL and further to investigate the impact of microvascular decompression (MVD) on QOL in patients with HFS. METHODS: Patients with HFS who underwent MVD in our department between 2013 and 2014 were included in this study. The validated, disease-specific questionnaire (HFS-30) was used to evaluate the QOL in patients with HFS before surgery and one year after MVD...

Microsurgery is a technically demanding field with long learning curves. Robotic-assisted microsurgery has the ability to decrease these learning curves. We, therefore, sought to assess the feasibility of robotic-assisted microvascular surgery in a rat model, and whether this could be translated into a worthwhile skills acquisition exercise for residents. Twenty-eight rats underwent microvascular anastomosis. Procedures were performed by a trained microvascular surgeon with no robotic experience (n = 14), or a trained robotic surgeon with no microvascular experience (n = 14)...
