Lukas Birkner
Lemierre's syndrome is a rare disorder that is characterized by anaerobic organisms inducing a thrombophlebitis of the internal jugular vein (IJV) following a course of oropharyngeal infection. It often occurs in young and healthy patients. Clinicians continuously misinterpret early symptoms until infection disseminates systematically and life-threatening sepsis transpires. We report the case of a 58-year-old female developing Lemierre's syndrome accompanied by invasive ventilation support and a profound deafness requiring the implementation of a cochlear implant...

Persistent left superior vena cava is a rare vascular anatomical variant. Although ultrasonography has facilitated the process of central venous catheterization, it cannot be used to locate the tip of a catheter. Postprocedure chest X-ray is desirable for locating the course and tip of the catheter. In our case, initial ultrasonography demonstrated the absence of the right internal jugular vein. This prompted insertion of a central venous catheter on the left side of the neck in the presence of normal vascular anatomy...

PURPOSE OF REVIEW: Central venous catheters (CVCs) have a prominent role in the diagnostic and therapy of neonates and children. Herein, we describe the multiple indications for CVC use and the different devices available for central venous access. Given the prevalent use of CVCs, healthcare systems are focused on reducing complications from their use, particularly central line-associated bloodstream infections (CLABSIs). The most up-to-date information available sheds light on best practices and future areas of investigation...

OBJECTIVES: Doppler ultrasound (US) has been widely used to evaluate the cervical venous system of multiple sclerosis (MS) patients according to the hypothesis of chronic cerebrospinal venous insufficiency (CCSVI) with contradictory results. Venous anatomy and pathology can be examined with less operator-dependent magnetic resonance imaging (MRI). DESIGN: To assess the inter-observer agreement in measuring internal jugular vein (IJV) cross-sectional area (CSA) in MR-images and to explore the agreement between US and MRI in the detection of calibres of ≤ 0...

An anterolateral thigh flap was salvaged using 110 medical leeches in the absence of an available vein for reanastomosis. After surgical construction of the flap for full-thickness thoracic wall reconstruction, the patient developed complete venous occlusion. Specifically, the anastomotic vein developed complete occlusion, and the internal jugular vein had a thrombus. In addition, because the lung was posterior to the flap, the angiogenic area of the flap was very small. When the medical leeches were first applied, the flap showed prominent venous congestion...

E H Chapel, B A Scansen
Two English bulldogs referred for interventional palliation of severe pulmonary valve stenosis were incidentally diagnosed with unilateral absence of an external jugular vein (left in one case, right in the other) by computed tomography and Doppler ultrasound. The right internal jugular vein also could not be visualized in the dog with absence of the left external jugular vein. Cervical venous anomalies can impact diagnostic or interventional venous catheterization procedures such as balloon pulmonary valvuloplasty...

OBJECTIVE: To report a case of successful surgical removal of a guide wire lost during central venous catheterization. CASE SUMMARY: A 28 kg, 4-year-old female neutered mixed breed dog presented to the primary care veterinarian with diabetic ketosis. During the process of central venous catheterization, the guide wire was accidently released and the entire length of the guide wire slipped into the jugular vein. Due to the absence of nearby interventional radiology facilities, surgical intervention was proposed...

PURPOSE: Trained breath-hold divers hyperinflate their lungs by glossopharyngeal insufflation (GPI) to prolong submersion time and withstand lung collapse at depths. Pulmonary hyperinflation leads to profound hemodynamic changes. METHODS: Thirteen divers performed preparatory breath-holds followed by apnea with GPI. Filling of extrathoracic veins was determined by ultrasound and magnetic resonance imaging and peripheral extravasation of fluid was assessed by electrical impedance...

Isolated unilateral abducens nerve palsy is usually due to ischemia, trauma or neoplasm. Dorello's canal is the space between the petrous apex and superolateral portion of the clivus, bound superiorly by Gruber's ligament. The abducens nerve travels with inferior petrosal sinus (IPS) though the Dorello's canal before entering the cavernous sinus. A 31-year-old man presented with neck pain, and binocular horizontal diplopia, worse looking towards left and at distance. He had a history of intravenous drug abuse but no history of hypertension or diabetes...

PURPOSE: Although neuroradiologists and skull base neurosurgeons are aware of the existence of veins within the clivus, such vessels have seldom been described in the literature. The aim of the present study is to elucidate the detailed venous structure of the clivus. METHODS: Computed tomography digital subtraction venography (CT-DSV) images of 50 unruptured aneurysm cases were examined retrospectively. RESULTS: Eighteen emissary veins were identified in 14 (28...

Extracalvarial meningioma in the cervical region presenting as a parapharyngeal mass lesion is seldom encountered in clinical practice and poses great challenge in its diagnosis and surgical management. In this report, we present a case of extracranial meningioma in a middle-aged person who presented with a large, gradually progressing cervical swelling with multiple cranial nerve pareses. The difficulties in diagnosis and surgical management of this unusual neoplasm in the setting of partial encasement and thrombosis of the internal jugular vein have been discussed, along with the computed tomography and magnetic resonance imaging providing details of its extent and character...

Limited literature regarding the incidence of cannula associated deep vein thrombosis (CaDVT) following veno-venous extracorporeal membrane oxygenation (VV ECMO) exists. The purpose of this study was to identify the incidence of post decannulation CaDVT and identify any associated risk factors. Forty eight patients were admitted between August 2014 and January 2016 to the Lung Rescue Unit were included in the study. Protocolized anticoagulation levels (partial thromboplastin time 45-55 second) and routine post decannulation DVT screening were in place during the study period...

Central venous catheter insertion and cancer represent some of the important predisposing factors for deep venous thrombosis (DVT). DVT usually develops in the lower extremities, and venous thrombosis of the upper extremities is uncommon. Early diagnosis and treatment of deep venous thrombosis are of importance, because it is a precursor of complications such as pulmonary embolism and postthrombotic syndrome. A 47-year-old woman visited our department with painful swelling on the left side of her neck. Initial examination revealed swelling of the region extending from the left neck to the shoulder without any redness of the overlying skin...

OBJECTIVE: The Valsalva maneuver is recognized as an effective method to dilate the internal jugular vein (IJV). However, this maneuver cannot be performed in many cases, such as children and unconscious patients. The aim of this study was to evaluate the effectiveness of proximal IJV compression, which can easily be performed, regardless of patient cooperation. METHODS: Healthy adult volunteers were recruited from tertiary hospital employees. Basic anatomic and physiologic data were collected...

BACKGROUND: Neurofibromas originating from vagus nerves are rarely reported in the literature. In particular, plexiform neurofibromas of the bilateral cervical vagus nerve are extremely rare. CASE PRESENTATION: A 21-year-old female presented with a 2-year history of swelling on the right side of her neck. Physical examination revealed a soft-tissue mass on the right side of her neck. Ultrasonography (US) and magnetic resonance (MR) imaging showed a tumor centered in the right carotid sheath between the internal jugular vein and the common carotid artery...

OBJECTIVES: Central venous access in critically ill, small infants remains technically challenging even in experienced hands. Several vascular accesses exist, but the subclavian vein is often preferred for central venous catheter insertion in infants where abdominal malformation and/or closure of the vein preclude the use of umbilical venous catheters, as catheterization of the subclavian vein is easier in very short necks than the internal jugular vein for age-related anatomical reasons...

BACKGROUND: In mandibular reconstruction with vascularised free fibula transfer, there are situations where the neck on the operated site lacks recipient vessels for vascular anastomosis due to previous radiological/surgical interventions. METHODS: The present study aims to clarify the availability of neck vessels on the contralateral side in such situations. Experimental surgery was conducted on 20 fresh cadavers (six males and 14 females). After the left half of the mandible was removed, free vascularised fibula of equivalent length was transferred to fill the defect...

The internal jugular vein (IJV) is an important vascular structure for oncologists and radiologists and is also a frequently used central venous route. The variations in the pattern of its course, and knowledge of its variations, are important. During the anatomical dissection of a 70-year-old male cadaver, fenestration involving a short segment (2.5 cm) of the right IJV in the superior part of the carotid triangle and a large dilatation (phlebectasia) of the IJV, involving its nonfenestrated segment were found - a case that has not previously been reported...

OBJECTIVES: The cervical part of the vagus nerve (CVN) has become an important target for stimulation therapy to treat epilepsy and psychiatric conditions. For this purpose, the CVN is visualized in the carotid sheath, assuming it to be localized dorsomedially between the carotid artery (CA) and the internal jugular vein (JV). The aim of our morphological study was therefore to revisit the CVN relationships to the CA and JV, hypothesizing it to have common variations to this classical textbook anatomy...
