Background: Intracerebral hemorrhage (ICH) is associated with a large hematoma that causes compression, increased intracranial pressure (IICP), midline shift, and brain herniation, and may ultimately lead to death. Urgent surgical removal of the large hematoma can ameliorate these injuries, which would be life-saving, but has not improved clinical outcome. A suitable animal model that mimics the clinically relevant human severe ICH injury requiring surgical hematoma evacuation is urgently needed.

Background: Transvenous coil embolization (TVCE) is a common and effective treatment for cavernous sinus dural arteriovenous fistulas (CSDAVFs). However, some patients may experience residual fistulas or worsening visual symptoms after the procedure. This study aimed to compare the effectiveness of transvenous coil and Onyx embolization (TVCOE) with TVCE in treating CSDAVFs.

Introduction And Importance: Direct carotid-cavernous fistulas (CCF) are primarily caused by head trauma. Some cases have also been attributed to iatrogenic injuries during endovascular procedures. However, the reports of functional endoscopic sinus surgery (FESS) associated with direct CCFs are extremely rare.

A male patient in his 70s with chronic schizophrenia, who could previously walk independently, developed a gait disturbance without any significant neurological deficit. Initially, his short step length and unstable gait were thought to be related to extrapyramidal symptoms caused by medication side effects. We tapered his antipsychotic medication, but the unstable gait persisted.

Intracerebral hemorrhage (ICH) is the most lethal type of cerebral stroke without effective therapy. Although clinical trials with various surgeries have been conducted, none have improved clinical outcomes compared to the current medical management for ICH. Several ICH animal models, including autologous blood injection, collagenase injection, thrombin injection, and microballoon inflation methods, have been developed to elucidate the underlying mechanisms of ICH-induced brain injury.

Objectives: The influence of chronic liver disease (CLD) on emergent neurosurgical outcomes in patients with spontaneous intracerebral hemorrhage (ICH) remains unclear. CLD is usually associated with coagulopathy and thrombocytopenia, which contribute to a high rebleeding rate and poor prognosis after surgery. This study aimed to confirm the outcomes of spontaneous intracranial hemorrhage in patients with CLD after emergent neurosurgery.

Background: Endovascular coil embolization has become an important method in the management of intracranial aneurysm. However, simultaneously coiling multiple intracranial aneurysms (MIAs) in unilateral parent artery in one-stage may fail or insufficient in geographic difficult aneurysm. Flow diverter (FD) has the potential to manage MIAs with nonamenable to coiling.

Biogas is one of the most common sources of biomass energy. Due to the associated environmental pollution and costs, desulfurization, and purification are the most important challenges of biogas power generation. Using all-atom molecular dynamics (MD), we systematically simulated the isothermal adsorption behavior of biogas (comprising CH, CO, HO, HS, and H) in graphite (Gr) slit nanopores.

Background: Traumatic vascular injury in the extremities may be associated with a low mortality rate but can lead to limb loss that seriously affects patients' functionality. Multiple scoring systems have been designed to evaluate the prognosis, but none are 100% predictive. The management of traumatic vascular injury remains challenging and depends mostly on the surgeon's experience.

Background: Endovascular aneurysm coiling is a minimally invasive method to manage intracranial aneurysms. However, aneurysm coiling may fail in very small aneurysms (VSAs); thus, flow diverter (FD) is recommended as an alternative in these difficult aneurysms. Herein, we report our experience and outcomes of FD to treat VSA of the internal carotid artery (ICA).

Background: Endovascular coil embolization is an important method for managing intracranial aneurysms. However, aneurysm coiling may fail or be insufficient in geographically difficult aneurysms. A flow-diverter stent (FDS) is an alternative in these difficult coiling aneurysms.

Cough is a pivotal airway protective reflex, yet the effects of prolonged mechanical ventilation (PMV) on cough function are unknown. This study compared the cough function in subjects with PMV (≥ 21 days, n = 29) and those with short-term mechanical ventilation (SMV, ≤ 7 days, n = 27). Cough reflex sensitivity was measured by capsaicin provocation concentrations after extubation.

Background: Carotid blowout syndrome (CBS) is a catastrophic complication after aggressive head and neck cancer treatment. Endovascular embolization is an effective modality to manage CBS. However, some CBS may have recurrent CBS (rCBS) after endovascular management.

Phlegmasia cerulea dolens is an acute fulminating form of extensive venous thrombosis. Limb loss, post-thrombotic syndrome and life-threatening conditions can occur without appropriate management. Treatment methods vary; there presently is no consensus on the best form of treatment.

Background: Endovascular repair is an alternative to surgical treatment for ascending aortic syndromes for those at high risk. We present our experience of endovascular repair for acute type A aortic dissections and intramural hematomas and discuss the outcomes.

Methods: From January 2015 to May 2018, six patients diagnosed with acute type A aortic dissections or type A intramural hematoma underwent endovascular procedures in our hospital.

Objectives: Direct microsurgical clipping for complex middle cerebral artery (MCA) aneurysms may require a long ischemic time. Sacrifice of the parent artery with trapping or endovascular coiling also may lead to ischemic stroke. We described our institutional experience with the treatment of complex MCA aneurysms using extracranial-intracranial (EC-IC) (superficial temporal artery [STA]-MCA) bypass.

The internal carotid artery is the most commonly affected artery in pseudoaneurysm presenting with epistaxis. Basilar arterial pseudoaneurysm is usually associated with intracranial haemorrhage. We report a basilar artery pseudoaneurysm after endoscopic surgery for clival chordoma, leading to epistaxis.

Aim: Refractory ventricular fibrillation, resistant to conventional cardiopulmonary resuscitation (CPR), is a life threatening rhythm encountered in the emergency department. Although previous reports suggest the use of extracorporeal CPR can improve the clinical outcomes in patients with prolonged cardiac arrest, the effectiveness of this novel strategy for refractory ventricular fibrillation is not known. We aimed to compare the clinical outcomes of patients with refractory ventricular fibrillation managed with conventional CPR or extracorporeal CPR in our institution.

Insecticide-resistant Drosophila melanogaster strains represent a resource for the discovery of the underlying molecular mechanisms of cytochrome P450 constitutive over-expression, even if some of these P450s are not directly involved in the resistance phenotype. For example, in select 4,4'-dichlorodiphenyltrichloroethane (DDT) resistant strains the glucocorticoid receptor-like (GR-like) potential transcription factor binding motifs (TFBMs) have previously been shown to be associated with constitutively differentially-expressed cytochrome P450s, Cyp12d1, Cyp6g2 and Cyp9c1. However, insects are not known to have glucocorticoids.

Sutureless repair is an effective procedure for acute left ventricular free wall rupture; however, it may be complicated with a left ventricular pseudoaneurysm during the late postoperative period. We present a case of a large ventricular pseudoaneurysm that occurred after the sutureless repair of an inferior myocardial infarction with oozing left ventricular free wall rupture. The patient underwent aneurysmectomy successfully.

Cardiac myxoma is a rare but curable cause of ischemic stroke. Current guidelines do not address the use of intravenous thrombolysis for embolic stroke caused by cardiac myxoma. The risk of hemorrhage due to occult tumor emboli or microaneurysms is a major concern.

The coronary artery anatomy of complete transposition with situs solitus/levocardia (CTSSL) has been well elucidated in the current era of arterial switch operation. However, coronary artery for complete transposition with situs solitus/dextrocardia (CTSSD) has never been documented. Coronary anatomy of transposition and aortopulmonary rotation were identified by angiography or surgical intervention from 1988 to 2007 at our hospital.
