OBJECTIVE: The central venous access port (CVAP) has played an important role in the safe administration of chemotherapy and parenteral nutrition. The aim of the present study was to clarify the optimal access vein for CVAP implantation when performed by residents rather than attending surgeons. METHODS: A consecutive cases of CVAP implantation via the subclavian vein (SV) using a landmark-guided technique or via the internal jugular vein (JV) using an ultrasound-guided technique were divided into 2 groups according to whether the intervention was performed by a resident or an attending surgeon...

Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis minimizes the risk of intracranial bleeding compared with systemic full-dose fibrinolytic therapy for pulmonary embolism (PE). However, major bleeding is nevertheless a potential complication. We analyzed the 150-patient SEATTLE II trial of submassive and massive PE patients to describe those who suffered major bleeding events following ultrasound-facilitated, catheter-directed, low-dose fibrinolysis and to identify risk factors for bleeding. Major bleeding was defined as GUSTO severe/life-threatening or moderate bleeds within 72 hours of initiation of the procedure...

BACKGROUND: Prevalent hemodialysis patients with vascular access consisting of a central venous catheter (CVC) are continuously increasing over the years. Improvement in evolution and CVC placement procedures represents therefore an essential tool to enhance performance and reduce intraoperative and long-term CVC complications. Internal jugular vein (IJV) catheterization techniques are different according to ultrasound probe position in relation to vein axis and to needle direction in relation to ultrasound beam...

BACKGROUND: For the nephrologist practicing in resource-limited settings, vascular ultrasound is often unavailable; consequently, blind percutaneous puncture of large veins is often employed to establish vascular access for hemodialysis. METHODS: To examine the efficacy and safety of this approach we evaluated 53 consecutive patients in whom central vascular access was required. The vascular access route utilized was primarily the right internal jugular vein. In the majority of cases, the indication for central vascular access was hemodialysis...

BACKGROUND: Cannulation of the internal jugular vein may be associated with inadvertent puncture of the common carotid artery. Systematic use of ultrasound guidance has improved clinical success rates and reduced complications, but better knowledge of topographic relationships of the internal jugular vein and common carotid artery is desirable. This preclinical study was designed to determine by ultrasound technique relative topographic characteristics in humans of the internal jugular veins and common carotid arteries at different levels on both sides of the neck...

OBJECTIVE: We hypothesized that decreasing vein compliance would protect the vein against stretch injury and reduce intimal hyperplasia (IH). BACKGROUND: Although arteriovenous fistulas (AVFs) are the criterion standard for vascular access, their effectiveness is limited by poor patency with 40% to 60% failing due to IH. Venous stretch injury from exposure to arterial pressure induces IH. Photochemical tissue passivation (PTP) crosslinks adventitial collagen, decreasing vein compliance to resemble that of an artery...

Central venous access has traditionally been performed on the basis of designated anatomical landmarks. However, due to patients' individual anatomy and vessel pathology and depending on individual operators' skill, this landmark approach is associated with a significant failure rate and complication risk. There is substantial evidence demonstrating significant improvement in effectiveness and safety of vascular access by realtime ultrasound (US)-guidance, as compared to the anatomical landmark-guided approach...

OBJECTIVE: In patients with a high risk of fistula immaturity, we created arteriovenous fistulas (AVFs) combined with brachial artery superficialization. With this procedure, the superficialized arteries are used as drawing routes and the AVFs as returning routes. This is a technical report about AVFs combined with brachial artery superficialization. METHODS: Twenty-four consecutive patients with a high risk of fistula immaturity who underwent AVFs with brachial artery superficialization were included in this single-center retrospective study...

Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible...

BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

Therapeutic plasma exchange (TPE) is often an isolated specialty with very little research, especially in regard to the mode of access. This lack of information drove this attempt at reviewing the use of arterio-venous fistulas (AVF) in TPE, and specifically the issue of monitoring the accesses patency. Using a Transonic®, we attempted to obtain a reading, using the Spectra Optia™ on a patient's access. Unfortunately, due to the limitations of the equipment, we were unable to get a reading. Our conclusion is that we will have to monitor using other approaches, such as physical assessment and ultrasound...

Extracorporeal membrane oxygenation (ECMO) is used as a lifesaving rescue treatment in refractory respiratory or cardiac failure. During venovenous (VV) ECMO, the presence of recirculation is known, but quantification and actions to minimize recirculation after measurement are to date not routinely practiced. In the current study, we investigated the effect of draining cannula design on recirculation fraction (Rf) during VV ECMO; conventional mesh cannula was compared with a multistage cannula. The effect of adjusting cannula position was also studied...

Ultrasound (US) guided needle positioning is safer than anatomical landmark techniques for central venous access. Hand-eye coordination and execution time depend on the professional's ability, previous training and personal skills. Needle guidance positioning systems (GPS) may theoretically reduce execution time and facilitate needle positioning in specific targets, thus improving patient comfort and safety. Three groups of healthcare professionals (41 anaesthesiologists and intensivists, 41 residents in anaesthesiology and intensive care, 39 nurse anaesthetists) were included and required to perform 3 tasks (positioning the tip of a needle in three different targets in a silicon phantom) by using successively a conventional US-guided needle positioning and a needle GPS...

BACKGROUND: The easy internal jugular (Easy IJ) technique involves placement of a single-lumen catheter in the internal jugular vein using ultrasound guidance. This technique is used in patients who do not have suitable peripheral or external jugular venous access. The efficacy and safety of this procedure are unknown. OBJECTIVE: We aimed to estimate efficacy and safety parameters for the Easy IJ when used in emergency department (ED) settings. METHODS: We conducted a prospective study of the Easy IJ in stable ED patients with severe intravenous access difficulty...
