A 50-year-old male was admitted to Intensive Care Unit with head and chest injury needed multiple central venous catheter (CVC) for the long-term intravenous access. Right internal jugular vein was cannulated uneventfully, and the tip of CVC was confirmed in the chest radiograph along the right border of the mediastinum. After few days, left subclavian vein was cannulated and the procedure was uneventful. However, the postprocedure Chest X-ray showed the CVC along the left border of mediastinum rather than the right border...

INTRODUCTION Central venous catheterisation (CVC) is a commonly performed procedure in a wide variety of hospital settings and is associated with appreciable morbidity. There is a paucity of literature focusing on mechanical complications specifically in the trauma setting. The aim of our study was to determine the spectrum of mechanical complications in a high-volume trauma centre in a developing world setting where ultrasound guidance was not available. METHODS A retrospective study was performed analysing data from a four-year period at the Pietermaritzburg Metropolitan Trauma Service in South Africa...

OBJECTIVE Neural interface technology may enable the development of novel therapies to treat neurological conditions, including motor prostheses for spinal cord injury. Intracranial neural interfaces currently require a craniotomy to achieve implantation and may result in chronic tissue inflammation. Novel approaches are required that achieve less invasive implantation methods while maintaining high spatial resolution. An endovascular stent electrode array avoids direct brain trauma and is able to record electrocorticography in local cortical tissue from within the venous vasculature...

BACKGROUND: Acute kidney injury requiring renal replacement therapy (RRT) in the intensive care unit portends a poor prognosis. The decisions regarding dialysis catheter placement is based mainly on physician discretion with little evidence to support the choice of dialysis catheter location. METHODS: The Veterans Affairs/National Institutes of Health Acute Renal Failure Trial Network Study was a multicenter, prospective, randomized trial of intensive vs. less intensive RRT in critically ill patients with AKI...

OBJECTIVES: Although real-time ultrasound guidance during central venous catheter insertion has become a standard of care, postinsertion chest radiograph remains the gold standard to confirm central venous catheter tip position and rule out associated lung complications like pneumothorax. We hypothesize that a combination of transthoracic echocardiography and lung ultrasound is noninferior to chest radiograph when used to accurately assess central venous catheter positioning and screen for pneumothorax...

An elderly male presented for emergent repair of a ruptured abdominal aortic aneurysm. For anticipated volume resuscitation, vasopressor administration, and hemodynamic monitoring, a large-bore central venous catheter was placed in the left internal jugular vein under ultrasound guidance before surgical incision. Initially, there were no readily apparent signs of venous perforation. However, a massive left hemothorax developed because of perforation of the brachiocephalic vein and violation of the pleural space...

A 46-year-old man underwent redo bilateral sequential lung transplantation for rapidly progressive bronchiolitis obliterans syndrome that developed 3.5 years after initial transplantation. In the operating room, he was sedated and intubated with a dual lumen endotracheal tube with subsequent single right-lung ventilation and left allograft implantation. His pulmonary arterial pressure became elevated with reperfusion of the newly implanted left lung, which required initiation of cardiopulmonary bypass to facilitate implantation of the right lung...

BACKGROUND: Due to the high incidence of thromboembolic events (deep venous thrombosis [DVT] and pulmonary embolus [PE]) after injury, many trauma centers perform lower extremity surveillance duplex ultrasounds. We hypothesize that trauma patients are at a higher risk of upper extremity DVTs (UEDVTs) than lower extremity DVTs (LEDVTs), and therefore, all extremities should be evaluated. MATERIALS AND METHODS: A retrospective chart and trauma registry review of Intensive Care Unit trauma patients with upper and LEDVTs detected on surveillance duplex ultrasound from January 2010 to December 2014 was carried out...

The Centers for Disease Control and Prevention guidelines for the prevention of catheter-related bloodstream infections suggest using "a subclavian site, rather than an internal jugular or a femoral site, in adult patients." This recommendation is based on evidence of lower rates of thrombosis and catheter-related bloodstream infections in patients with subclavian central venous catheters (CVCs) compared to femoral or internal jugular sites. However, preference toward a subclavian approach to CVC insertion is hindered by increased risk of mechanical complications, especially pneumothorax, when compared to other sites...

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...

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...
