Weight had more effect then height on VTE. Discussion As research informatics tools develop and more clinical data become available in EHR, it is important to study and understand unique opportunities for clinical research informatics to transform the scale and resources needed to perform certain types of clinical research.
Conclusions With the right clinical research informatics tools and EHR data, some types of very large cohort studies can be completed with minimal resources. Ultrasound guidance for internal jugular vein cannulation: Continuing Professional Development. The objective of this continuing professional development module is to describe the role of ultrasound for central venous catheterization and to specify its benefits and limitations.
Although ultrasound techniques are useful for all central venous access sites, the focus of this module is on the internal jugular vein approach. In recent years, several studies were published on the benefits of ultrasound use for central venous catheterization. This technique has evolved rapidly due to improvements in the equipment and technology available. Ultrasound helps to detect the anatomical variants of the internal jugular vein. Cost-benefit analyses show that the cost of ultrasound equipment is compensated by the decrease in the expenses associated with the treatment of complications.
In this article, we will review the history of ultrasound guidance as well as the reasons that account for its superiority over the classical anatomical landmark technique. We will describe the equipment needed for central venous catheterization as well as the various methods to visualize with ultrasound. To improve patient safety, we recommend the use of ultrasound for central venous catheterization using the internal jugular approach. New treatment of vertigo caused by jugular bulb abnormalities.
Jugular bulb abnormalities can induce tinnitus, hearing loss, or vertigo. Vertigo can be very disabling and may need surgical treatments with risk of hearing loss, major bleeding or facial palsy. Hence, we have developed a new treatment for vertigo caused by jugular bulb anomalies, using an endovascular technique. Three patients presented with severe vertigos mostly induced by high venous pressure. One patient showed downbeat vertical nystagmus during the Valsalva maneuver.
The temporal-bone computed tomography scan showed a high rising jugular bulb or a jugular bulb diverticulum with dehiscence and compression of the vestibular aqueduct in all cases. We plugged the upper part of the bulb with coils, and we used a stent to maintain the coils and preserving the venous permeability. After to month follow-up, those patients experienced no more vertigo, allowing return to work. The 3-month arteriographs showed good permeability of the sigmoid sinus and jugular bulb through the stent, with complete obstruction of the upper part of the bulb in all cases.
Disabling vertigo induced by jugular bulb abnormalities can be effectively treated by an endovascular technique. Summary: Microvascular free tissue transfer is one of the most common techniques of reconstruction for complex head and neck surgical defects. Generally, venous thrombosis is more likely to occur than arterial thrombosis in vascular anastomosis.
Thus, recipient veins must be chosen carefully. Although the internal jugular vein is preferred as a recipient vein by many microsurgeons, internal jugular vein thrombosis is a potential complication, as shown in our report. Therefore, we consider that the external jugular vein still is an option as a recipient for venous anastomosis and that it is better to perform multiple vein anastomoses with 2 different venous systems, such as the internal and external jugular systems, than anastomoses within the same venous system.
The preferred site of insertion is one with fewer risks and easier access. Although the right internal jugular vein is preferred, on occasion, the left internal jugular may have to be accessed.

A patient was admitted for septic shock, cerebrovascular accident, and non-ST-segment elevation myocardial infarction. A central venous line was needed for antibiotic and vasopressor administration. Due to trauma from a fall to the right side and previously failed catheterization attempts at the left subclavian and femoral veins, the left internal jugular vein was accessed.
On chest radiography for confirmation, the left internal jugular central venous catheter was seen projecting down the left paraspinal region. A left-sided SVC is present in approximately 0.
During placements of central venous lines and pacemakers, irritation of the coronary sinus may result in hypotension, arrhythmia, myocardial ischemia, or cardiac arrest. A widened mediastinum can be an indication of a duplicated SVC. When attempting a left internal jugular vein central venous catheter placement, it is important to be aware of venous anomalies in order to prevent complications.
Umbilical venous -arterial plasma composition differences suggest differential incorporation of fatty acids in NEFA and cholesteryl ester pools. The developing fetus requires an adequate supply of fatty acids, in particular PUFA, for optimal growth and development. Little is known about the transfer of fatty acids by the placenta into the fetal circulation.
However, the molecular form in which fatty acids are transferred into the fetal circulation may influence their metabolism and hence their availability to specific tissues. The aim of the present study was to determine which lipid pools in the fetal circulation become enriched in fatty acids from the placenta by comparing the fatty acid compositions of individual lipid pools between umbilical venous UV and umbilical arterial UA plasma. Plasma from the UV and UA was collected after delivery from ten uncomplicated pregnancies, and the fatty acid composition of each lipid class was determined by GC.get link

Such partitioning may facilitate supply of individual fatty acids to specific fetal tissues. Transcatheter closure of a large patent ductus arteriosus using jugular access in an infant. Trans-catheter device closure of patent ductus arteriosus PDA via femoral route is the commonly used, safe and effective procedure.
Trans- jugular approach has been successfully used in older children with interrupted inferior vena cava. We report a case of successful occlusion of PDA using Amplatzer duct occluder ADO via trans- jugular approach following difficulties encountered in gaining femoral venous access.
A 6-month-old male infant, weighing 8 kg was admitted for percutaneous catheter closure of PDA. Echocardiogram showed a 4. Femoral venous access was not possible; therefore, we decided to use a trans- jugular approach. Successful closure of the duct was confirmed with an aortogram. Post procedure echocardiogram showed no residual shunt across the duct. We highlight that trans-catheter closure of PDA using jugular venous access is safe and effective even in infants.
Mondel, Prabath Kumar, E-mail: prabathmondel gmail. In patients with syndromic craniosynostosis, definitive repair of jugular diverticulum by open surgery is fraught with high risk of bleeding, poor functional outcomes, and even death. On computed tomography, a defect in the roof of jugular fossa containing jugular venous diverticulum immediately inferior to the bony external auditory canal was seen.
Jugular veins in transient global amnesia: innocent bystanders. Transient global amnesia TGA has been associated with an increased prevalence of internal jugular valve insufficiency and many patients report Valsalva-associated maneuvers before TGA onset. These findings have led to the assumption of hemodynamic alterations in intracranial veins inducing focal hippocampal ischemia. We investigated this hypothesis in patients with TGA and control subjects.

Seventy-five patients with TGA and 75 age- and sex-matched healthy subjects were enrolled into a cross-sectional study. Extracranial and transcranial high-resolution venous echo-color-Doppler sonography was performed blindly in all patients and control subjects. Blood flow direction and velocities were recorded at the internal jugular veins, basal veins of Rosenthal, and vein of Galen, both at rest and during Valsalva-associated maneuvers. Mean age of patients with TGA was Internal jugular valve insufficiency left, right, or bilateral was found to be more frequent in patients with TGA than in control subjects: 53 This study, although confirming the association between TGA and internal jugular valve insufficiency, challenges the hypothesis that cerebral venous congestion plays a significant role in the pathogenesis of TGA.
Purpose: During the past two decades, radiosurgery has arisen as a promising approach to the management of glomus jugulare. In the present study, we report on a systematic review and meta-analysis of the available published data on the radiosurgical management of glomus jugulare tumors. Methods and Materials: To identify eligible studies, systematic searches of all glomus jugulare tumors treated with radiosurgery were conducted in major scientific publication databases. The data search yielded 19 studies, which were included in the meta-analysis.
The data from glomus jugulare patients were extracted.
