OJECTIVE: Ultrasound guided central venous catheterization (CVC) is a common surgical procedure with complication rates ranging from 5 to 21 percent. Training is typically performed using manikins that do not simulate anatomical variations such as obesity and abnormal vessel positioning. The goal of this study was to develop and validate the effectiveness of a new virtual reality and force haptic based simulation platform for CVC of the right internal jugular vein. DESIGN: A CVC simulation platform was developed using a haptic robotic arm, 3D position tracker, and computer visualization...

Small for size and flow syndrome (SFSF) is one of the most challenging complications following extended hepatectomy (EH). After EH, hepatic artery flow decreases and portal vein flow increases per 100 gram remnant liver volume (RLV). This causes hypoxia followed by metabolic acidosis. A correlation between acidosis and post-hepatectomy liver failure has been postulated, but not studied systematically in a large animal model or clinical setting. In our study, we performed stepwise liver resections on nine pigs to defined SFSF limits as follows: step 1: segment II/III resection, step 2: segment IV resection, step 3: segment V/VIII resection (RLV: 75%, 50% and 25% respectively)...

Primary hyperparathyroidism (pHPT) causes hypercalcemia. The treatment for pHPT is surgical dissection of the hyperfunctioning parathyroid gland. Lower rates of hypocalcemia and recurrent laryngeal nerve injury imply that minimally invasive parathyroidectomy (MIP) is safer than bilateral neck resection. Current trends in MIP use can be inferred only by reference to preoperative localization studies. Noninvasive imaging studies (typically preoperative localization studies) show good detection rates of hyperfunctioning glands; however, there have also been cases of nonlocalization or discordant results...

A standardized combined Doppler-electrocardiography technique was developed for measurement of the triphasic waveform characteristics in the internal jugular vein. Flow velocities at the A, X, V and Y peaks, the RR interval and the PA and RX times were measured. From these the venous impedance index ([X-A]/X) and the ratios PA/RR and RX/RR were calculated. Six measurements were performed at three different locations by two ultrasonographers in 21 randomly selected pregnant and non-pregnant women. Statistical models proved the feasibility and reproducibility of this technique, with the highest concordance correlation coefficients in the right distal internal vein...

BACKGROUND: Intracranial pressure (ICP) is directly related to cranial dural venous pressure (P dural ). In the upright posture, P dural is affected by the collapse of the internal jugular veins (IJVs) but this regulation of the venous pressure has not been fully understood. A potential biomechanical description of this regulation involves a transmission of surrounding atmospheric pressure to the internal venous pressure of the collapsed IJVs. This can be accomplished if hydrostatic effects are cancelled by the viscous losses in these collapsed veins, resulting in specific IJV cross-sectional areas that can be predicted from flow velocity and vessel inclination...

We report a rare complication of right brachiocephalic vein perforation during ultrasound-guided cannulation of the right internal jugular vein (IJV) in a patient with a tortuous common carotid artery (CCA). We suspect that the tortuous CCA displaced the IJV, which caused misplacement of the J-tip guidewire into the subclavian vein. The stiff dilator sheath introduced over the guidewire then perforated the wall of the brachiocephalic vein, causing massive hemothorax. This was diagnosed by videothoracoscopy...

Jung A Lim, Chan Hee Jee, Kyung-Hwa Kwak
RATIONALE: The misplacement of central venous catheter (CVC) can occur more often at the left jugular vein than the right side due to anatomic differences. And many of the previously reported cases are about catheter misplacement resulting from vessel penetration associated with guidewire. This case differs that the catheter itself through the sheath introducer can cause venous injury that may lead to the malposition of CVC particularly through an approach to the left internal jugular vein...

We present a case of an iatrogenic lymphocutaneous fistula secondary to placement of a tunneled, large bore (14.5 Fr) right-sided internal jugular vein for plasmapheresis to treat antibody-mediated kidney transplant rejection. While iatrogenic lymphatic leaks caused by neck and thoracic surgeries are well described in the literature, lymphatic leak or lymphocutaneous fistula resulting from image-guided placement of a central venous catheter through the right internal jugular vein has yet to be described. We also describe the successful percutaneous treatment of this lymphocutaneous fistula using a combination of n-butyl cyanoacrylate glue and embolization coils...

BACKGROUND: Measurement of cerebral venous oxyhemoglobin saturation (ScvO2) is considered a gold standard in assessing the adequacy of tissue oxygen delivery (DO2) after the stage 1 palliation (S1P), with SvO2 <30% often representing severely compromised DO2. Regional oxygenation index (rSO2) based on near-infrared resonance spectroscopy (NIRS) frequently is used to screen for compromised DO2, although its sensitivity to detect severe abnormalities in SvO2 is uncertain. METHODS: ScvO2 was measured by co-oximetry from the internal jugular vein as clinically indicated in 73 neonates after S1P...

Objective Chronic cerebrospinal venous insufficiency (CCSVI) is a condition associated with multiple sclerosis (MS). One mechanism that has been proposed is that the venous obstructions found in MS are due to a chronic persistent venulitis caused by the intra-cellular bacterial parasite, Chlamydophila pneumoniae (Cpn). The objective of the current study is to determine the effect of a combined antibiotic protocol (CAP) on the venous flow in MS patients as measured by a quantitative duplex ultrasound examination (QDUS)...

Inferior vena cava abnormalities or agenesis had to be suspected in front of technical difficulties during venous catheterization. In the setting of extracorporeal life support and during chest compressions, femoral vascular access is the easiest, most efficient and, perhaps, the first approach for a successful extracorporeal cardiopulmonary resuscitation. In the case of inferior vena cava agenesis leading to cannulation failure and/or complications, the use of the right internal jugular vein for salvage venous cannulation is a potential life-saving strategy...

An 18-year-old gentleman with a history of recurrent tonsillitis presented to the emergency room complaining of worsening sore throat. He was found to have a peritonisillar abscess, and imaging revealed a non-occlusive left internal jugular vein thrombosis. Lemierre's syndrome is a rare, potentially fatal condition characterized by internal jugular vein thrombosis with septicemia following an acute oropharyngeal infection. While anticoagulation is the mainstay of treatment of deep venous thromboembolism (DVT) and pulmonary embolism (PE), the use of therapy is controversial in septic thrombophlebitis...

PURPOSE: To quantify the acute effect of the head-down tilt (HDT) posture on intracranial hemodynamics and hydrodynamics. MATERIALS AND METHODS: We evaluated the intracranial physiological parameters, blood flow-related parameters, and brain morphology in the HDT (-6° and -12°) and the horizontal supine (HS) positions. Seven and 15 healthy subjects were scanned for each position using 3.0 T magnetic resonance imaging system. The peak-to-peak intracranial volume change, the peak-to-peak cerebrospinal fluid (CSF) pressure gradient (PGp-p ), and the intracranial compliance index were calculated from the blood and CSF flow determined using a cine phase-contrast technique...

Establishing a long-term vascular access in patients exhibiting vascular access exhaustion is challenging. In this study, we reported a case of a direct catheterization in the superior vena cava of a hemodialysis patient with vascular access exhaustion and original dysfunctional catheter inserted via the left internal jugular vein. The direct catheterization was performed with cuffed tunnel catheter (CUFF) and guided by digital subtraction angiography (DSA) and multidetector computed tomography venography (MDCTV)...
