Arteriovenous malformations consist of tangles of arteries and veins that are often connected by a fistula. The causes and mechanisms of these clinical entities are not fully understood. We discovered that suturing an arterial patch into the common jugular vein of rabbits led to spontaneous neovascularization, the formation of an arteriovenous fistula and the development of an arteriovenous shunt. An arterial patch excised from the common carotid artery was sutured into the common jugular vein. Within a month, a dense nidus-like neovasculature formed around the patch...

Background: Several studies using Doppler ultrasound have suggested cerebral venous drainage is through paravertebral venous plexus due to the collapse of internal jugular veins in an upright position. Methods: We present a technique of acquiring venographic images during an upright position as part of catheter-based angiography to provide additional information regarding cerebral venous diseases. Angiographic images in anteroposterior projection were acquired in lying position and after patients were placed at 60° using radiolucent supporting wedges on angiographic table...

Background : An estimated 125,711 face-lifts and 54,281 neck-lifts were performed in 2015. Regardless of the technique employed, facial and neck flap elevation carries with it anatomical risk of which any surgeon performing these procedures should be aware of. Statistics related to anterior jugular vein injury during these procedures have not been published. Objective : To define a "danger zone" that will contain both of the anterior jugular veins on the basis of anatomical landmarks to aid surgeons with planning their surgical approach during rhytidectomy in the anterior neck region...

We report a case of intravenous lobular capillary hemangioma in the subclavian vein, causing venous thoracic outlet syndrome. A 32-year-old woman was referred to our unit with facial and left arm oedema. Ultrasound evaluation, computed tomography and magnetic resonance imaging showed a hypervascular mass in the middle portion of the subclavian vein, with arrest of venous flow. Through an infraclavicular approach, we excised the venous axis with the endovascular palpable tumour that extended from the axillary-subclavian junction to the jugular-subclavian junction, without reconstruction...

Vein graft failure limits the long-term patency of the saphenous vein used as a conduit for coronary artery bypass graft. Early graft adaptation involves some degree of intima hyperplasia to sustain the hemodynamic stress, but the progress to occlusion in some veins remains unclear. We have demonstrated that stretch-induced up-regulation of cysteine and glycine-rich protein 3 (Crp3) in rat jugular vein and human saphenous vein in response to arterialization. Here, we developed a Crp3-KO rat to investigate the role of Crp3 in vascular remodeling...

Lemierre's syndrome is a condition characterised by suppurative thrombophlebitis of the internal jugular (IJ) vein following a recent oropharyngeal infection, with resulting septicaemia and metastatic lesions. It is strongly associated with Fusobacterium necrophorum, a Gram-negative bacilli. Key to early diagnosis is awareness of the classical history and course of this illness, and therefore to ask about a history of recent oropharyngeal infections when a young patient presents with fever and rigors. Diagnosis can be confirmed by showing thrombophlebitis of the IJ vein, culturing F necrophorum from normally sterile sites or demonstrating metastatic lesions in this clinical setting...

Superior vena cava (SVC) syndrome is a group of clinical signs caused by the obstruction or compression of SVC and characterized by edema of the head, neck, and upper extremities, shortness of breath, and headaches. The syndrome may be caused by benign causes but most of the cases are caused by lung or mediastinal malignant tumors. Stenting of SVC has become widely accepted as the palliative treatment for this condition in malignant diseases, as it offers rapid relief of symptoms and improves the quality of life...

Superior vena cava (SVC) stenosis or thrombosis is a well-known complication of central venous catheterization for endocavitary treatments, hemodialysis, or chemotherapy. In cancer patients, these SVC lesions are often symptomatic due to intimal damage and chemotherapy toxicity. We report our experience with six patients treated between 2007 and 2012 via an endovascular approach (n=5) or a direct surgical approach (n=1). All patients had SVC syndrome with facial edema, headache and upper limb edema. In three cases, the catheter was in place when the clinical symptoms occurred...

The jugular bulb is a venous structure linking the sigmoid sinus with the internal jugular vein. Jugular diverticulum is a rare condition characterized by extraluminal outpouching from the jugular bulb. As the patients may be totally asymptomatic, but sensorineural symptoms such as sensorineural hearing loss, tinnitus and vertigo can also occur. Diagnosis of these patients can be made by some radiologic methods such as high-resolution computerized tomography, magnetic resonance imaging, or a novel radiologic technique flat panel computed tomography...

PURPOSE: Although involvement of the osseous component with an anterior condylar dural arteriovenous fistula (AC-DAVF) has been frequently described, osseous venous structures in which AC-DAVFs develop have not been fully elucidated. We investigated osseous venous structures adjacent to the hypoglossal canal in normal controls and patients with AC-DAVFs. METHODS: The study included 50 individuals with unruptured aneurysms as normal controls and seven patients with AC-DAVFs...

BACKGROUND: Cardiogenic pulmonary edema (CPE) is a life-threatening emergency necessitating aggressive management. We conducted this study to test the hypothesis that a combination of N-terminal pro-b-type natriuretic peptide (NT-pro-BNP) and some relevant clinical factors may provide better predictability for CPE in heart failure (HF) patients. METHODS: This retrospective study enrolled adult HF patients hospitalized during January 2011 to December 2013. After determining the independent predictors for the occurrence of CPE, a novel NT-pro BNP-based diagnostic score for predicting CPE was established...

A persistent left-sided superior vena cava (PLSVC) is the most frequent abnormality of the venous system; however, it is not a very well-known variation among physicians. Herein we report the case of a patient with a PLSVC who was diagnosed after central venous catheterization (CVC). An 80-year-old man was admitted to the emergency room with cardiopulmonary arrest. After the return of spontaneous circulation, CVC was blindly performed from the left jugular vein without any complications. However, routine chest X-ray after catheterization revealed that the catheter was moving down directly to the left heart...

Glomus jugulare tumor (GJT) is a rare benign neoplasm that is located in the skull base; it is impossible for ultrasonography to detect it in most cases. In this article, we present the case of a rare giant GJT, which extended into the internal jugular vein in the neck, initially detected by ultrasonography and confirmed by MRI and pathology. We highlight the initial ultrasonography findings and review the literature to summarize the ultrasonographic features of GJT.
