Introduction In case of cavernous sinus dural arteriovenous fistula (CSDAVF), transvenous embolization (TVE) of the cavernous sinus (CS) via the inferior petrosal sinus (IPS) is generally performed. However, various approach routes have been reported when the accessibility of the IPS is challenging. We herein report a case of CSDAVF treated by TVE with direct puncture of the facial vein. Case report A 70-year-old woman who suffered from tinnitus, chemosis, diplopia and bruit was referred to our hospital. Digital subtraction angiography (DSA) demonstrated CSDAVF...

BACKGROUND: Tricuspid valve surgery has been the de facto standard treatment for tricuspid valve endocarditis (TVE) refractory to medical therapy. It is now possible to remove right-sided vegetations percutaneously using a venous drainage cannula with an extracorporeal bypass circuit. OBJECTIVES: The purpose of our study is to describe our single-center experience of percutaneous tricuspid valve vegetation removal. METHODS: We reviewed the perioperative course of 33 consecutive patients with large tricuspid valve vegetations who carried high surgical risk...

BACKGROUND: The aim of this paper was to establish a minimally invasive method for deriving the left ventricular time varying elastance (TVE) curve beat-by-beat, the monitoring of which's inter-beat evolution could add significant new data and insight to improve diagnosis and treatment. The method developed uses the clinically available inputs of aortic pressure, heart rate and baseline end-systolic volume (via echocardiography) to determine the outputs of left ventricular pressure, volume and dead space volume, and thus the TVE curve...

Infective endocarditis of the tricuspid valve (TVE) occurs predominantly in selected groups of patients including intravenous drug users (IVDUs). The most often cultured pathogen in IVDUs is Staphylococcus aureus. Eikenella corrodens, normally existing as a commensal in the mouth and the upper respiratory tract, is identified as an etiologic pathogen of endocarditis very rarely. The authors describe a case of a 27-year-old male with a past history of staphylococcal TVE readmitted to hospital after 5 months due to progression of right-sided heart failure...

BACKGROUND: Spinal arteriovenous shunts are a common spinal vascular disorder. However, they can have a misleading clinical presentation and poor prognosis. They are classified into 4 types according to shunt points and drainage route, among which extradural arteriovenous fistula (eAVF) is the most rare, comprising only 1% of all spinal arteriovenous shunts. We report an extremely rare case of coexistent eAVF at the craniocervical junction and soft tissue arteriovenous malformation within the same metamere...

BACKGROUND: Recipient hepatectomy can be complicated by severe bleeding during caudate lobe dissection in living-donor liver transplantation (LDLT), especially when the inferior vena cava is encased or with dense adhesions from prior interventions. Total hepatic vascular exclusion (TVE) including total hepatic inflow (Pringle maneuver) and occlusion of supra- and infra-hepatic inferior vena cava during the partial hepatectomy has been studied well, but it has not been mentioned regarding recipient hepatectomy in LDLT...

OBJECTIVES: Low tidal volume (TVe) ventilation improves outcomes for ventilated patients, and the majority of clinicians state they implement it. Unfortunately, most patients never receive low TVes. 'Nudges' influence decision-making with subtle cognitive mechanisms and are effective in many contexts. There have been few studies examining their impact on clinical decision-making. We investigated the impact of 2 interventions designed using principles from behavioural science on the deployment of low TVe ventilation in the intensive care unit (ICU)...

The present study was conducted to investigate changes in uncuffed endotracheal tube (ETT) leak during laparoscopic surgery. The study included 31 patients aged between 1 and 6 years scheduled for elective laparoscopic inguinal herniorrhaphy. Inspiratory and expiratory tidal volumes (TVi and TVe) were measured during mechanical ventilation, and ETT leak was calculated using the formula-ETT leak = (TVi - TVe)/TVi × 100 (%), assessed at the following time-points-5 min after the start of mechanical ventilation (T1, baseline), just before the start of surgery (T2), 5 min after the induction of pneumoperitoneum with 15° Trendelenburg tilt (T3), and at the end of surgery (T4)...

The current work was undertaken to investigate the potential effectiveness of Thymus vulgaris ethanolic extract (TVE) against Toxoplasma gondii infection in chronic experimental toxoplasmosis. To evaluate prophylactic effects, mice received 500 mg/kg TVE for 5 days before they were infected by an avirulent Me49 T. gondii strain. To investigate the therapeutic effects of the extract postinfection, daily treatment with TVE was initiated at 6 weeks postinfection and continued for 10 days. The following groups of animals were used as controls: uninfected/non-treated, infected/non-treated, and infected/treated with a combination of pyrimethamine and sulfadiazine...

INTRODUCTION: While total vascular exclusion (TVE) with veno-venous bypass and hypothermia may be undertaken to increase liver tolerance for complex liver resection, these procedures are still associated with elevated rates of postoperative complications and mortality. In particular, one of the main issues of this strategy is the management of bleeding after declamping, which is enhanced by both hypothermic state and acidosis. To overcome this high risk of morbidity, several technical refinements might be undertaken and here described (with video)...

The use of stereotactic radiosurgery (SRS) expanded to include the treatment of vestibular schwannomas (VSs) in 1969; since then, efforts to increase tumour control and to reduce cranial neuropathy have continued. Using the currently recommended marginal dose of 12-13 Gy, long-term reported outcomes after SRS include not only excellent tumour control rates of 92-100 % but also outstanding functional preservation of the trigeminal and facial nerves, with values of 92-100 % and 94-100 %, respectively. Nonetheless, hearing preservation remains in the range of 32-81 %...

BACKGROUND: The 2009 pandemic influenza A/H1N1 developed as a novel swine influenza which caused more diseases among younger age groups than in the elderly. Severe hypoxemic respiratory failure from A/H1N1 pneumonia resulted in an increased need for ICU beds. Several risk groups were identified that were at a higher risk for adverse outcomes. Pregnant women were a particularly vulnerable group of patients The CDC reported on the first ten patients with severe illness and acute hypoxemic respiratory failure associated with A/H1N1 infection, none of whom were pregnant, but they noticed that half of the patients had a pulmonary embolism...

PURPOSE: We report a case of cavernous sinus dural arteriovenous fistula (dAVF) that developed after the treatment of a transverse-sigmoid sinus dAVF using transvenous embolization (TVE). CASE PRESENTATION: A 72-year-old woman presented with headache and left-sided tinnitus. Angiography demonstrated the presence of a left transverse-sigmoid sinus dAVF. After TVE, the patient's symptoms completely disappeared. Three years later, she complained of left-sided tinnitus and diplopia, and angiography revealed the presence of a left cavernous sinus dAVF...

OBJECTIVE: Identify learning needs of students of Technical Vocational Education (TVE) in Nursing. Qualitative study conducted in a city of São Paulo state. METHOD: The subjects were students, teachers and coordinators of TVE and students of the bachelor degree who have had contact with TVE. Data collection was performed by questionnaire socioeconomic and cultural circles about the learning needs. For data analysis we used the content analysis. RESULTS: It was found that students have difficulties contents not related to nursing as portuguese and mathematics, as well as introductory courses in the course of TVE which possibly may interfere negatively in learning specific content of nursing and the quality of health care...

In embolization of a cavernous sinus (CS) by transvenous embolization (TVE) for a CS dural arteriovenous fistula (DAVF), selection of embolization coils is difficult owing to the complex anatomical structure of the CS. Moreover, overpacking of the CS with embolization coils may cause permanent cranial nerve palsies. The ED coil-10 (EDC-10) infini is an extremely soft platinum coil without shape-memory that has excellent conformability with surrounding structures. The goal of this study was to evaluate use of the EDC-10 infini coil for embolization of a CS DAVF...

Dural arteriovenous fistula (DAVF) involving the hypoglossal canal is rare but increasingly reported. To achieve complete obliteration without a procedure-related complication, understanding of the precise anatomy of this DAVF is essential. Here, we describe a 72-year-old man who underwent selective intra-arterial injection computed tomography angiography which allowed us to understand the detailed anatomy of the complex DAVF regarding access routes and the target regions for transvenous embolization (TVE)...

Endocarditis is characterized by vegetations, which is a mass of platelets, fibrin, micro-colonies of micro-organisms, and inflammatory cells, in the endocardium. Over the past three decades, the incidence of right-sided endocarditis has risen dramatically in Pakistan. We report a 36-year woman with a history of repeated intravenous analgesic injections for low back pain, presenting with high grade fever, sepsis and a white cell count of 44,000 with 90% neutrophils. Echocardiography showed large mobile vegetations on Tricuspid Valve (TV)...

INTRODUCTION: Although cavernous sinus (CS) dural arteriovenous fistulas (d-AVFs) are usually treated with transvenous embolization (TVE) via the inferior petrosal sinus (IPS), IPSs are sometimes thrombosed and angiographically invisible. In such cases, the first obstacle to TVE is detecting the entry to the IPS. We report a new technique for TVE via IPS using intravascular ultrasonography (IVUS). METHODS: Three consecutive cases of CS d-AVF with ipsilateral or bilateral IPS occlusion were involved in this study...
