The investigators aim to study whether surgical resurfacing of the sigmoid sinus and jugular bulb will result in elimination of venous pulsatile tinnitus.
This is a prospective, randomized, single-center clinical study aiming to explore the safety and efficacy of venous stenting for patients with internal jugular vein stenosis (IJVS).
Objectives: 1. To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound. 2. To evaluate the correlation of internal jugular vein cross sectional area and central venous pressure. Methods: 1. The study design is prospective observational study. 2. We will include all patients scheduled for cardiac surgery in Siriraj Hospital and reco...
Our hypothesis is that there will be a decrease in internal jugular venous flow in the park bench position when compared to the supine position. There will also be a change in blood flow between the right and left internal jugular veins in the park bench position. In particular, there will be a greater reduction of flow on the dependent side. However, the internal jugular venous flow will be the same in both the prone and supine positions.

Two approaches are possible when the first finder needle attempt of the internal jugular vein cannulation fails; the needle can be turned slightly laterally or the puncture point can be moved slightly medially. This study is an ultrasonographic stimulation study to evaluate the success rate of turning the needle laterally and moving the puncture point medially, and to determine the proper angle or distance for the second try of internal jugular vein cannulation.
The specific aim of the Gabapentin for the Relief of Idiopathic Subjective Tinnitus Trial is to assess the therapeutic benefit of Gabapentin (Neurontin®) for subjective idiopathic troublesome tinnitus. We employed a double-blind placebo-controlled randomized clinical trial design to assess the efficacy of Gabapentin. Adults, between the ages of 18 and 70 with idiopathic, subjective, troublesome, unilateral or bilateral, non-pulsatile tinnitus of 6 month's duration or greater ...
Comparison between internal jugular vein versus via axilar vein with single-incision for placement of implantable ports in cancer patients. Investigators are recruiting 240 patients and randomizing 120 for each arm. Primary outcome is early complications, until 30 days and secondary outcome late complications, between 30 days and 6 months. The follow-up is 12 months.
Two-dimensional ultrasound guided approach does not guarantee first attempt success on internal jugular vein cannulation. New attachable device recently was developed for accurate needle insertion when ultrasound is used. Our randomized parallel simulation study will examine whether this device will improve the first attempt success rate when ultrasound guided internal jugular vein catheterization of simulated internal jugular vein.
The jugular venous pulse (JVP) reflects changes in the right atrial pressure and its evaluation can be useful in managing many emergency conditions for guiding the fluid administration as well as in the diagnosis and/or prognosis of many heart and lung diseases. The present study aims: i) To validate a novel ultrasonographic (US) technique for obtaining the JVP from a high-resolution B-mode sonograms sequence, recording the changes of the cross-sectional area (CSA) of the inter...
This randomized, placebo-controlled study will compare the effects of HD-tDCS (a non-invasive neuromodulation technique) with a sham stimulation. In the sham situation, patients will undergo an identical treatment but no stimulation will be applied, allowing to control for placebo effects. This study will assess the effects of HD-tDCS on chronic, non-pulsatile tinnitus in a reliable way, as confounding factors such as anxiety, depression, hearing impairment, tinnitus gradation,...
A novel device attached to ultrasound probe designed to increase success rate and safety of internal jugular vein cannulation.
Somatosensory tinnitus is suspected when the tinnitus perception changes following head, neck, or jaw maneuvers. The prevalence of this type of tinnitus in Veterans in unknown. The Cleveland Clinic evaluates all tinnitus patients for this condition and when detected, prescribes individualized physiotherapy. Cleveland Clinic's novel approach to tinnitus assessment and management provides the framework for this proof of concept pilot study.
The Trendelenburg position is used to distend the central veins, improving both success and safety of vascular cannulation. The purpose of this study is to measure the cross-sectional area of the internal jugular vein (IJV) in three different positions, using surface ultrasound.
Ultrasound guidance has been established as an effective and safe method during insertion of internal jugular vein catheter.. Needle visualization during advancement toward the vein has a great impact on both safety and success of the procedure. Clinicians have adopted variable techniques to increase needle visualization including changing needle- probe relation (in-plane vs. out-of-plane), or using specific ultrasound needles The angle between the inserting needle and the prob...
This is an observational study intended to characterize the time-to-placement of peripherally-inserted internal jugular (PIJ) catheters in appropriate patients. As secondary outcomes and to ensure patient safety, the investigators will record and evaluate adverse outcomes, but the study is not powered to detect rare events.
Randomized controlled trial comparing femoral vs internal jugular insertion site of central venous catheters (CVC) in newborns and small infants undergoing cardiac surgery. The experimental hypothesis is that the jugular insertion site is superior to the femoral in terms of catheter colonization.
Transcranial Magnetic Stimulation is used to modulate the auditory neural pathways caused by hearing loss and leading to the phantom auditory perception of sound in the absence of an external or internal acoustic stimulus.
Tinnitus is the acoustic perception of sound without any physical source. It is estimated that 15-21% of adults develop a Tinnitus, which can cause serious distress and debilitation in all aspects of daily life of the affected. There is currently no evidence for a successful treatment of tinnitus. While one treatment approach involves sound-based therapies, e.g. tinnitus retraining therapy. The treatment aspect in our setting involved cognitive behavioural therapy.
Prospective validation of the ultrasound-assessed internal jugular vein distensibility (JVD) ratio to identify patients with systolic chronic heart failure and right atrial pressure (RAP) of 7 or less mmHg measured by the right heart catheterization. In a calibration cohort, a threshold ratio will be identified, above which the RAP is normal with the highest accuracy. This diagnostic tool with a defined threshold of the JVD ratio will be assessed in a second prospective validat...
After obtaining parental consent ultrasonographic evaluation of right internal jugular vein will be performed in pediatric patients undergoing elective surgeries between 0-2 years of age. The patients for whom central venous catheterization is indicated will be included. The success rates and outcomes of catheterization will be recorded.
This study aims to find out the effect of contra lateral head rotation to distance and overlapping of internal jugular vein and carotid artery at cricoid cartilage level by ultrasound guidance on the Malay race in Indonesia
This pilot study aims to increase the understanding of tinnitus through the identification of potentially altered brain networks in patients who are able to voluntarily control or alter their tinnitus. Upon completion of this study, new knowledge will be gained about the changes in brain activity in people who are able to modify their tinnitus.
The proposed research is to identify the brain areas activated or deactivated by tinnitus in humans. The identification of these areas is expected to be able to treat tinnitus refractory to traditional therapies by methods of brain stimulation. Furthermore, this technique would be very useful to verify the effectiveness of any treatment to relieve tinnitus. The brain activation measured during fMRI will be performed in a position of rest, after inhibition of tinnitus, an...
People with tinnitus will use a smartpphone app in which they are instructed to reject maladaptive thoughts by throwing them away from themselves (upwards) and embrace supportive thoughts by pulling them towards themselves (downwards). The Tinnitus Handicap Inventory will be used to measure the effect of the application.
