INTRODUCTION: Valvular disease and pulmonary hypertension are common conditions in haemodialysis patients. In presence of tricuspid regurgitation, an increased retrograde blood flow into the right atrium during ventricle systole results in a typical modification of the normal venous waveform, creating a giant c-v wave. This condition clinically appears as a venous palpable pulsation within the internal jugular vein, also known as Lancisi's sign. CASE REPORT: An 83-year-old woman underwent haemodialysis for 9 years...

Nasogastric tube (NGT) insertion is a routine procedure in the management of surgical patients. We report the second case of internal jugular vein perforation during NGT insertion. A 79-year-old man presented with diffuse abdominal pain secondary to a perforated viscus. Abdominal CT revealed pneumoperitoneum, necessitating emergent exploratory laparotomy. On post-operative Day 7, the patient developed mild abdominal distension and subjective nausea for which NGT placement was ordered for decompression. Tube placement was confirmed by insufflation of air without aspiration of gastric contents...

A previously healthy 5-week-old female was admitted for sepsis secondary to methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. After several days of hospitalization, she experienced acute decompensation in mental status despite having received targeted antibiotic therapy. Imaging revealed left peritonsillar/parapharyngeal space abscess, left venous thrombophlebitis of the internal jugular vein, and septic emboli of the lungs and brain consistent with Lemierre syndrome. Bedside needle aspiration of the parapharyngeal abscess confirmed MRSA involvement...

PURPOSE: Neointimal hyperplasia (NH) is considered to be one of the main causes of vascular access occlusion in patients receiving hemodialysis. Endothelial injury and TGF-β-mediated proliferation of vascular smooth muscle cells (VSMCs) induce NH. Endothelial microparticles (EMPs) are also increased by endothelial injury. We aimed to investigate the effects of EMPs and TGF-β expression on VSMC proliferation and their contributions to NH formation in an ex vivo model. METHODS: EMPs were collected from the culture media of human umbilical vein endothelial cells treated with indoxyl sulfate (IS, 250 µg/mL) after ultracentrifugation at 100,000 × g...

Accurate diagnosis of subtypes of transverse sinus (TS) hypoplasia requires more expensive methods like magnetic resonance (MR) imaging. We hypothesized ultrasound findings of the internal jugular vein (IJV) can be surrogate indicators for diagnosis of TS hypoplasia. MR images were reviewed in 131 subjects to evaluate TS diameter and the location and degree of venous flow stenosis and obstruction. Ultrasound parameters including the cross-sectional lumen area (CSA), time-average-mean velocity (TAMV), and flow volume (FV) at each IJV segment were also evaluated...

HYPOTHESIS: Internal jugular vein (IJV) compression influences not only intracranial but also intracochlear physiology and has demonstrated preclinical effectiveness in reducing acute audiological injury in a rodent blast model. However, the long-term effects in this model are unknown. BACKGROUND: Blast wave-induced audiological injury from an improvised explosive device is a leading cause of morbidity among service members in theater but there are limitations to the current protective measures...

Central venous catheter (CVC) insertion is associated with many potential complications; malposition of the catheter is one of them. A chest X-ray is routinely done to detect the malposition of catheter, but sometimes it has been seen that X-ray is time-consuming and its accuracy is also low for determining the exact position of the catheter tip. In our case, an ultrasonography (USG)-guided CVC was placed into the right internal jugular vein of the patient. As there was no ECG change obtained during insertion of guidewire and catheter, malposition was suspected, which was easily detected by a novel USG-guided saline flush test...

The regulation of cerebral venous outflow during exercise has not been studied systematically. To identify relations between cerebral arterial inflow and venous outflow, we assessed the blood flow (BF) of the cerebral arteries (internal carotid artery: ICA and vertebral artery: VA) and veins (internal jugular vein: IJV and vertebral vein: VV) during dynamic exercise using ultrasonography. Nine subjects performed a cycling exercise in supine position at a light and moderate workload. Similar to the ICA BF, the IJV BF increased from baseline during light exercise (P < 0...

Knowledge of variants in the formation and position of the ansa cervicalis is important in head and neck surgery, specifically in reconstructions of the tongue that use the infrahyoid muscles, and in the anastomosis of the ansa cervicalis to the recurrent laryngeal nerve when the laryngeal muscles have been paralysed. We describe a rare variant of the superior root of the ansa cervicalis, which had a contribution from the vagus and hypoglossal nerves. The inferior root was formed by the C2 and C3 ventral rami, but it passed medial to the internal jugular vein before it joined the superior root to form the loop...

Background: Central venous catheters (CVCs) are frequently used for monitoring haemodynamic status and rapidly delivering fluid therapy during the peri- and postoperative periods. Indwelling CVCs are typically used 7-14 days postoperatively for additional monitoring and treatment, but patients may develop asymptomatic catheter-related thrombosis, leading to life-threatening pulmonary embolism and death. Early detection helps to avoid such complications. Methods: This prospective observational study investigated the risk factors associated with catheter-related right internal jugular vein thrombosis in patients undergoing chest surgery...
