HYPOTHESIS: Internal jugular vein (IJV) compression before blast injury will lead to reduced risk of traumatic hearing injury following exposure to a blast injury. BACKGROUND: IJV compression and its effects on not only intracranial, but also intracochlear pressure may potentiate blast induced hearing injury, therefore, precluding its use as a prophylactic therapy for blast induced traumatic brain injury. METHODS: Twenty Sprague Dawley rats were exposed to a 17...

BACKGROUND: The continuous monitoring of vital parameters and subsequent therapy belong to the core duties of anaesthetists during acute trauma resuscitation in the trauma room. Important procedures may include placement of arterial lines and central venous catheters (CVCs). Knowledge of indication, performance and localization of invasive catheterisation of trauma care in Germany is scarce. METHODS: After approval of the German Society of Anaesthesiology and Intensive Care Medicine we conducted an online survey about arterial and central venous catheterisation of severely injured patients with consideration of common practice used by anaesthetists in German trauma rooms...

A new method for covering the internal jugular vein and carotid artery after exposure of the cervical vascular axis subsequent to neck dissection is presented. To cover the most caudal part of the vascular axis, a platysma coli muscle flap is harvested from its most medial and inferior part of the neck in a caudally based fashion and is slightly rotated posteriorly up to 45°. In addition, a superiorly based sternocleidomastoid muscle flap involving the posterior half of the muscle after detachment of the clavicle head is harvested and rotated 45° anteriorly to cover the upper two thirds of the vascular axis...

A 60-year-old man presented with a 10-month history of of stereotypical spells characterized by vertigo, tinnitus, blurred vision, left hemibody numbness, and occasional syncope, precipitated by turning his head leftwards. Cerebral angiography and CT angiography of the head and neck with provocative maneuvers did not demonstrate vertebral artery narrowing. However, there was narrowing of the left internal jugular vein due to extrinsic compression from the sternocleidomastoid with leftward head rotation in the setting of hypoplasia of the right internal jugular vein...

BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

PURPOSE: To assess the efficacy and safety of placing the tip of the internal jugular (IJ) hemodialysis catheter in the inferior vena cava (IVC) in situations where it does not work well when placed in the right atrium. METHODS: The medical records of chronic hemodialysis patients at an outpatient vascular intervention facility were retrospectively reviewed. Out of the 831 patients who had dialysis catheters exchanged over a 4-year period, 13 patients were identified who underwent catheter exchanges where the tip of the catheter was placed in the IVC via the IJ approach...

Pulsatile Tinnitus (PT) is a pulse-synchronous sound heard in the absence of an external source. PT is often related to abnormal flow in vascular structures near the cochlea. One vascular territory implicated in PT is the internal jugular vein (IJV). Using computational fluid dynamics (CFD) based on patient-specific Magnetic Resonance Imaging (MRI), we investigated the flow within the IJV of seven subjects, four symptomatic and three asymptomatic of PT. We found that there were two extreme anatomic types classified by the shape and position of the jugular bulbs: elevated and rounded...

BACKGROUND: Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is an ever-emerging method of managing respiratory failure in patients who are refractory to conventional mechanical ventilatory support. An increasingly common method of cannulation involves placement of a bicaval dual-lumen, single cannula via the right internal jugular (IJ) vein. Thrombus in this vein has been considered a contraindication for cannula placement. CASE REPORT: A 45-year-old Hispanic male presented with bleomycin-induced respiratory failure resulting in acute respiratory distress syndrome (ARDS)...

One hypothesized contributor to vision changes experienced by >75% of International Space Station astronauts is elevated intracranial pressure (ICP). While no definitive data yet exist, elevated ICP might be secondary to the microgravity-induced cephalad fluid shift, resulting in venous congestion (overfilling and distension) and inhibition of cerebrospinal and lymphatic fluid drainage from the skull. The objective of this study was to measure internal jugular venous pressure (IJVP) during normo- and hypo-gravity as an index of venous congestion...

BACKGROUND: Although central venous access for port placement is common and relatively safe, complications and poor resource utilization occur. We hypothesized that despite the simplicity of port placement, surgeon and/or resident performance-rather than technique-is associated with clinical outcomes and operating room efficiency. MATERIALS AND METHODS: Medical records of 1200 patients who underwent port placement between 2012 and 2015 at our institution were retrospectively reviewed...

BACKGROUND: The intended physiologic response to a fluid bolus is an increase in stroke volume (SV). Several ultrasound (US) measures have been shown to be predictive. The best measure(s) in critically ill surgical patients remains unclear. METHODS: This is a prospective observational study in critically ill surgical patients receiving a bolus of crystalloid, colloid or blood. A transthoracic echocardiogram (TTE) was performed before (pre-TTE) and after. A positive volume response (+VR) was defined as a ≥15% increase in SV...

Lemierre syndrome (LS) is a multisystemic infection beginning in the oropharynx and leading to thrombosis of the internal jugular vein (IJV) with septic emboli and potential thrombotic extension to the central nervous system. Although patient outcomes have improved with early initiation of antimicrobial therapies, there is no consensus regarding the role of anticoagulation in LS. To better define the role of anticoagulation therapy in LS and determine whether anticoagulation improves thrombosis outcomes, we conducted a retrospective chart review of pediatric and adult patients diagnosed with LS and managed at our institution from January 1998 to December 2014...

The infrahyoid muscles are involved in vocalisation and swallowing; among these, the sternothyroid muscle is derived from the common primitive sheet. The improper differentiation of this muscle may therefore result in morphological variations. We report an unusual variation found during the dissection of a 65-year-old male cadaver at the Sri Manakula Vinayagar Medical College, Madagadipet, Pondicherry, India, in 2015. An anomalous belly of the right sternothyroid muscle was observed between the internal jugular (IJ) vein and the internal carotid artery with an additional insertion into the tympanic plate and petrous part of the temporal bone and the presence of a levator glandulae thyroideae muscle...

Most of the studies on the incidence, pattern, and predictive factors of lymph node (LN) metastasis with papillary thyroid carcinoma (PTC) have been performed retrospectively and no common consensus has been reached regarding the predictors for the involvement of level I LNs. This study was conducted prospectively to determine the incidence and the possible predictors of level I involvement in N1b PTC patients. The study included 30 consecutive patients with N1b stage of PTC. All the patients underwent neck dissection (ND) including level I...

Due to the high risk of vascular and nerve damage during surgery, precise pre-operative evaluation of carotid body tumor (CBT) is important. We aim to apply intra-operative contrast-enhanced cone-beam CT (CBCT) with multi-volume technique in CBT evaluation, where the tumor, patent carotid arteries, and skull are demonstrated in three different colors, and to compare this novel technique with traditional computed tomography angiography (CTA). Seven CBT patients scheduled for traditional surgical removal were enrolled in this study between October 2013 and March 2016...
