Interictal gamma oscillation regularity analysis and susceptibility-weighted imaging on focal epilepsy cases with alcohol use disorders.

Background: There has been no clear consensus on the clinical markers to distinguish alcohol-related seizures (ARSs) from epileptic seizures. We have reported the usefulness of gamma oscillation (30-70 Hz) regularity (GOR) analysis using interictal electroencephalography (EEG) data to evaluate epileptogenic focus. We conducted interictal GOR analysis using scalp EEG and susceptibility-weighted imaging (SWI) to visualize the epileptogenic focus in two cases initially suspected to have ARS.

Unplanned hemodialysis initiation and low geriatric nutritional risk index scores are associated with end-stage renal disease outcomes.

Patients with end-stage renal disease (ESRD) have a low nutritional status and a high mortality risk. The geriatric nutritional risk index (GNRI) is a predictive marker of malnutrition. However, the association between unplanned hemodialysis (HD) and GNRI with mortality remains unclear.

Benefits and Risks of Delayed Surgery for Ventricular Septal Rupture after Acute Myocardial Infarction.

Objective: For thoracic endovascular aortic repair of the arch, branched and fenestrated endografts are available with different limitations regarding anatomy and extent of the pathology. Comparisons are lacking in the literature. The aim of this study was to compare the results of 2 currently commercially available devices for branched thoracic endovascular aortic repair and fenestrated thoracic endovascular aortic repair.

Interictal High Gamma Oscillation Regularity as a Marker for Presurgical Epileptogenic Zone Localization.

Background: To ensure that epilepsy surgery is effective, accurate presurgical localization of the epileptogenic zone is essential. Our previous reports demonstrated that interictal high gamma oscillation (30-70 Hz) regularity (GOR) on intracranial electroencephalograms is related to epileptogenicity.

Objective: To examine whether preoperative GOR analysis with interictal high-density electroencephalography (HD-EEG) improves the accuracy of epileptogenic focus localization and enhances postoperative seizure control.

Early mortality of emergency surgery for acute type A aortic dissection in octogenarians and nonagenarians: A multi-center retrospective study.

Early Clinical Outcomes of the Active Seal Technology of the AFX Endovascular Aortic Aneurysm System With the VELA Cuff for Patients With a Conical Proximal Neck.

Purpose: To evaluate the efficacy of the Active Seal technology employed in the AFX endovascular aortic aneurysm system (AFX), during endovascular aneurysm repair (EVAR) in patients with abdominal aortic aneurysms (AAAs) having a conical proximal neck.

Materials And Methods: A retrospective analysis of the EVAR for AAA with a conical proximal neck using the AFX was performed at 17 Japanese hospitals between January 2016 and August 2020. The conical proximal neck was defined as a cone-shaped proximal neck, with more than 10% diameter increase within a 15 mm length at the proximal landing zone.

Microsurgical management of midbrain cavernous malformations: does lesion depth influence the outcome?

Background: The purpose of this study was to clarify whether the intrinsic depth of midbrain cavernous malformations (MCMs) influenced the surgical outcome.

Methods: The authors conducted a retrospective study of 76 consecutive patients who underwent microsurgical resection of a MCM. The vascular lesions were categorized into 4 distinct groups based on how these lesions had altered the brainstem surface.

Transient hyperphosphatasemia: Possible association with pediatric acute respiratory infection.

Importance: Acute respiratory infections are quite prevalent in children. Transient hyperphosphatasemia (TH) is defined as the transient elevation of serum alkaline phosphatase (ALP) level, which occurs mainly in infants and children without liver or bone disorders. Although no apparent cause has been identified, a possible association of respiratory infections with TH has been reported in the literature.

Secondary Aortoesophageal Fistula Treated by Covered Esophageal Stent and Muscle Wrapping.

Secondary aortoesophageal fistula is rare but is associated with serious complications and high mortality. We devised a treatment strategy involving a covered esophageal stent, instead of esophageal resection, and placing the latissimus dorsi muscle around the infected aorta without removing the aorta and the stent graft. A 72-year-old man with a history of total arch replacement with a frozen elephant trunk for a thoracic dissecting aneurysm developed aortoesophageal fistula and underwent surgical treatment using our strategy.

Development of Acquired Factor V Inhibitor After Surgical Procedure Without the Use of Fibrin Tissue Adhesives: A Case Report.

Development of acquired factor V (FV) inhibitor is a rare coagulation disorder. Production of heteroantibodies against bovine FV, a contaminant in fibrin tissue adhesives, is a common cause of this condition in the field of surgery. The development of recombinant thrombin eliminated contamination of bovine FV, and infrequent use of bovine thrombin has decreased the risk of FV inhibitor development.

Epileptogenic zone localization using intraoperative gamma oscillation regularity analysis in epilepsy surgery for cavernomas: patient series.

Background: In epilepsy surgery for cavernoma with intractable focal epilepsy, removal of the cavernoma with its surrounding hemosiderin deposition and other extended epileptogenic zone has been shown to improve postsurgical seizures. However, there has been no significant association between such an epileptogenic zone and intraoperative electrocorticography (ECoG) findings. The authors recently demonstrated that high regular gamma oscillation (30-70 Hz) regularity (GOR) significantly correlates with epileptogenicity.

Surgical Treatment for Primary Mycotic Aneurysms Using Endovascular Therapy, Focusing on Patient Selection: Single-Center Experience.

Mycotic aneurysms (MAs) are relatively rare but life-threatening. Some recent reports have described the use of endovascular therapy for their treatment; however, this still is a controversial treatment, and a definite target population has not been determined. We performed surgery on 34 patients with MAs from March 2005 to March 2019.

Optimal access route for pontine cavernous malformation resection with preservation of abducens and facial nerve function.

Objective: The aim of this study was to analyze the differences between posterolateral and posteromedial approaches to pontine cavernous malformations (PCMs) in order to verify the hypothesis that a posterolateral approach is more favorable with regard to preservation of abducens and facial nerve function.

Methods: The authors conducted a retrospective analysis of 135 consecutive patients who underwent microsurgical resection of a PCM. The vascular lesions were first classified in a blinded fashion into 4 categories according to the possible or only reasonable surgical access route.

Influence of Luminal Communication on Aortic Enlargement after Hemiarch Replacement for Acute Type A Aortic Dissection.

Background: Aortic enlargement after hemiarch replacement (HAR) for acute type A aortic dissection (AAAD) is a serious problem. We reviewed our experience and analyzed the risk factors for aortic enlargement.

Methods: During April 2005 to December 2017, 364 patients underwent HAR for AAAD.

Distal Neo-Neck Formation for Chronic Type B Dissection: False Lumen Closure After TEVAR.

Objectives:: Patients with chronic aortic dissection often require repeat interventions due to enlargement of the pressurized false lumen or disseminated intravascular coagulation even after additional thoracic endovascular aortic repair (TEVAR) to occlude the entry tear. Residual false lumen flow can persist even after performing the candy-plug technique or branched stent-graft placement in some cases. We have devised a new method for false lumen closure.
