A consensus on venous flow quantification using echo spectral Doppler sonography is lacking. Doppler sonography data from 83 healthy individuals were examined using manually traced transverse cross-sectional area and diameter-derived cross-sectional area obtained in longitudinal view measurements of the internal jugular vein. Time-averaged velocity over a 4-s interval was obtained in the longitudinal plane using manual tracing of the waveform. Manual and computer-generated blood flow volume calculations were also obtained for the common carotid artery, for accuracy purposes...

Objective and Importance Lemierre's syndrome (LS) is a rare condition that typically starts with a bacterial oropharyngeal infection complicated by a thrombophlebitis of the internal jugular vein and septic emboli to the lungs or other organs. The most common organism isolated is Fusobacterium necrophorum, although other causative organisms are isolated in rare cases. Case presentation We discuss a case of LS in a 44-year-old, previously healthy man presenting with an oropharyngeal infection. F. necrophorum was isolated from blood cultures and Computed tomography of the chest demonstrated septic emboli in the lungs...

OBJECTIVE: Cervical vestibular-evoked myogenic potentials (cVEMPs) are short-latency vestibulocollic reflexes. The damage on any point of the vestibulocollic reflex pathway could affect the cVEMPs. Whether neck dissection has an effect on the sacculocollic pathway, and consequently on cVEMPs, remains unexplored. The aim of this study was to evaluate the cVEMP findings in patients with functional neck dissection without vestibular symptoms. PATIENTS AND METHODS: This cross-sectional study design, 20 patients who had undergone unilateral neck dissection with sparing of the accessory nerve, SCM and internal jugular vein, were included...

BACKGROUND: The Easy IJ procedure involves placement of a 4.8-cm intravenous catheter into the internal jugular (IJ) vein using ultrasound guidance. It is not known whether this needle length has the potential to cause a pneumothorax. OBJECTIVE: The objective of this study was to determine if a radiographic "safe margin" exists. We hypothesized that an average margin of ≥2 cm would exist between the catheter tip and the pleura. METHODS: Operators used a central approach to the IJ vein...

Nerve and vein preserving modification of the radical neck dissection is commonly used in the management of oral squamous cell cancers. There is limited literature addressing nerve function and vein patency following treatment. We prospectively analysed 65 patients with nerve conduction study using surface electromyography at baseline, 1 month and 6 months post-surgery and colour Doppler of the internal jugular vein at baseline and 1 month post-surgery. We also studied functional outcomes of nerve sparing with arm abduction test and Neck Dissection Quality of Life questionnaire...

Bezold's abscess is a very rare extracranial complication of acute mastoiditis. Lateral sinus thrombosis is another intracranial complication of acute mastoiditis that can occur, but there are only few reports of concomitant ispilateral Bezold's abscess and lateral sinus thrombosis with favorable outcome. We diagnosed and treated successfully a 14-year-old girl suffering from Streptococcus pneumoniae acute mastoiditis complicated with Bezold's abscess and lateral sinus thrombosis. Surgical treatment included myringotomy, cortical mastoidectomy, and Bezold's abscess incision and drainage...

Objective: Central venous cannulation of the internal jugular vein is difficult in paediatric patients because of the small size of the vein and anatomic variations. Many studies have shown the accuracy of various formulae for calculating the depth of placement. The aim of this study was to assess the most reliable method for central venous catheter (CVC) tip placement in paediatric patients. Methods: Sixty-nine patients in the age groups from 0 to 12 years were divided in three groups for three published techniques for catheter tip placement...

REVIEW
Chun-Wai Ngai, Pauline Yeung Ng, Wai-Ching Sin
Veno-venous extracorporeal membrane oxygenation (VV-ECMO) has been traditionally delivered with two independent cannulae at different venous insertion sites. The bicaval dual lumen cannula has gained popularity as a cannula for simultaneous venous drainage and reinfusion of blood via the internal jugular vein (IJV). Its insertion requires special attention to details to prevent the occurrence of serious complications. In this review, we discuss different techniques of cannula insertion and tips for troubleshooting...

Background and Aims: Increasing the cross-sectional area (CSA) of the internal jugular vein (IJV) improves the success rate of cannulation and decreases complications. Application of positive end-expiratory pressure (PEEP) may increase the CSA of IJV beyond that achieved in Trendelenburg position. However, the optimum PEEP to achieve maximal increase in CSA of IJV and the effect of PEEP on IJV and CA relationship is not known. Methods: In this prospective, blinded, randomised controlled study, 120 anesthetised paralysed patients of the American Society of Anesthesiologists physical Status I-II were placed in 20° Trendelenburg position...

OBJECTIVE Exposure of the vertebral artery (VA) between C-1 and C-2 vertebrae (atlantoaxial VA) may be necessary in a variety of pathologies of the craniovertebral junction. Current methods to expose this segment of the VA entail sharp dissection of muscles close to the internal jugular vein and the spinal accessory nerve. The present study assesses the technique of exposing the atlantoaxial VA through a newly defined muscular triangle at the craniovertebral junction. METHODS Five cadaveric heads were prepared for surgical simulation in prone position, turned 30°-45° toward the side of exposure...
