High-intensity interval exercise (HIIE) improves cerebral executive function (EF), but the improvement in EF is attenuated after repeated HIIE, perhaps because of lower lactate availability for the brain. This investigation examined whether improved EF after exercise relates to brain lactate uptake. Fourteen healthy, male subjects performed 2 HIIE protocols separated by 60 min of rest. Blood samples were obtained from the right internal jugular venous bulb and from the brachial artery to determine differences across the brain for lactate (a-v difflactate), glucose (diffglucose), oxygen (diffoxygen), and brain-derived neurotrophic factor (BDNF; diffBDNF)...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is characterized by abnormally elevated intracranial pressure (ICP) without identifiable etiology. Recently, however, a subset of patients with presumed IIH have been found with isolated internal jugular vein (IJV) stenosis in the absence of intracranial abnormalities. METHODS: Fifteen consecutive patients were screened from 46 patients suspected as IIH and were finally confirmed as isolated IJV stenosis. The stenotic IJV was corrected with stenting when a trans-stenotic mean pressure gradient (∆MPG) was equal or higher than 5...

BACKGROUND: Ventriculo-atrial (VA) shunt is a routine technique for the treatment of hydrocephalus. Correct position at superior vena cava-right atrium junction is generally assessed by X-ray. We herein present the first experience of an alternative, non-radiographic technique to assess the distal end of the VA-shunts through an electrocardiographic (EKG) method. Such a technique is mutuated from the very large experience on central-venous catheters (CVC) worldwide: the EKG-guided method is a common and validated alternative to the standard radiological control of the location of the tip of any CVC...

Recently, a percutaneous right ventricular assist device (RVAD) called the TandemLife Protek Duo (TPD; TandemLife, Pittsburgh, PA) has been introduced. The Protek Duo (TPD) is a temporary RVAD placed via the right internal jugular vein, capable of providing up to 4.5 L of flow. We report a two-center experience using the TPD in 17 patients with right ventricular (RV) failure, 12 of whom were post-left ventricular assist device (LVAD) implantation.

INTRODUCTION: Differentiated thyroid carcinomas (DTC) have good prognoses after complete resection. Nevertheless, when DTC is associated with an aerodigestive invasion, curative surgery is difficult to perform. However, there is no established neoadjuvant therapy for advanced DTC. PRESENTATION OF CASE: A 73-year-old man with thyroid papillary carcinoma was referred to our hospital. A computed tomography examination revealed a tumor in the upper right lobe of the thyroid, and multiple bilateral enlarged lymph nodes in the neck, involving the surrounding structures...

Upper extremity deep vein thrombosis is an extremely important clinical entity with potential for considerable morbidity and mortality. A 64-year-old woman was brought to the emergency department with complaints of left upper limb and neck swelling for 4 days. Ultrasonography of the neck showed thrombosis of the left internal jugular and other surrounding veins associated with local lymphadenopathy. Computed tomography (CT) of the neck also showed a hypodense 0.6 cm × 0.8 cm × 1.2 cm lesion in the right middle lobe bronchus, causing complete occlusion and collapse of the right middle lobe of the lung...

AIMS: Treatment of advanced ischemic cardiomyopathy is often challenging, with recurrent episodes of cardiac decompensation and consequent need for multiple hospitalizations. Mixed outcomes have been previously reported after conventional surgical left ventricle(LV) reconstruction. Aim of this report is to describe a novel hybrid transcatheter technique to reconstruct the remodeled LV. METHODS AND RESULTS: In this manuscript, we provide a detailed step-by-step description of a novel procedure, called Less Invasive Ventricular Enhancement(LIVE), which reconstructs the remodeled LV by plication of anteroseptal LV scar, thus reducing the enlarged volume, decreasing wall stress and increasing ejection fraction...

Tracheobronchial rupture by a double-lumen endobronchial tube is a rare but life-threatening complication. We report a case of bronchial rupture during contralateral bilobectomy. Venovenous extracorporeal membrane oxygenation support was instituted via the right femoral vein and the internal jugular vein with the patient in the left lateral decubitus position. Sleeve resection of the ruptured bronchus was performed. The patient was successfully discharged home. Rapid institution of venovenous extracorporeal membrane oxygenation is helpful to manage this intraoperative complication...

A minimally invasive ventricular assist device is under development for percutaneous insertion into the left atrium via transseptal access from the right atrium (RA). This study aimed to mathematically describe the vascular anatomy along possible insertion pathways to determine the device's maximum outer dimensions. We developed 2-dimensional mathematical models describing the vascular anatomy to the RA from three access points: subclavian vein (SCV), internal jugular vein (IJV), and femoral vein (FV). All pathways terminated by turning from the superior or inferior vena cava (SVC/IVC) into the RA...

Cerebral non-oxidative carbohydrate consumption may be driven by a β2-adrenergic mechanism. This study tested whether the 46G > A (G16R) single nucleotide polymorphism of the β2-adrenergic receptor gene (ADRB2) influences the metabolic and cerebrovascular responses to administration of adrenaline. Forty healthy Caucasian men were included from a group of genotyped individuals. Cardio- and cerebrovascular variables at baseline and during a 60-min adrenaline infusion (0.06 μg kg(-1) min(-1)) were measured by Model flow, near-infrared spectroscopy and transcranial Doppler sonography...

CLINICAL INTRODUCTION: A 72-year-old woman presented with an 8-year history of palpitations occurring every few weeks. They were sudden in onset, were associated with dizziness and could last for up to 2 hours. She was prescribed bisoprolol which reduced the frequency of events but did not abolish them. Baseline ECG and echocardiography were normal. She was referred for electrophysiological study. Despite initial difficulties, diagnostic catheters were placed in the right ventricular (RV) apex and in the coronary sinus (CS) via the right internal jugular vein and superior vena cava (SVC) (figure 1A)...

Omohyoid muscle present in cervical region is of particular importance to anatomists as it defines anteriorly the carotid triangle and divides the posterior cervical triangle. It has superior and inferior bellies and an intermediate common tendon. Like sternohyoid, sternothyroid and thyrohyoid muscles, omohyoid is also an infrahyoid muscle, but it differs from them in its course. The infrahyoid muscles are formed from a muscle primordium occurring in the anterior cervical area. Anderson (Anderson, 1881) theorized that the superior belly of the omohyoid muscle is a true infrahyoid muscle, whereas the inferior belly most likely shares a common embryology with the subclavius muscle...

The knowledge of both normal and abnormal anatomy of the veins of the neck may be important for surgeons performing neck surgery, to avoid inadvertent injury to vascular structures. In a 75-year-old man candidated to carotid endarterectomy preoperative CT-scan showed a rare anomaly of the venous drainage in the area of the anterior jugular vein (AJV), that usually begins in the suprahyoid region via the confluence of several superficial veins, to open into the ipsilateral external jugular vein. A large left sided venous trunk, originating from an anomalous proximal confluence with the internal jugular vein, descended in the AJV anatomical position, to cross over the sternum draining into the right subclavian vein...
