BACKGROUND: Unintended arterial puncture occurs in 2%-4.5% of central venous catheterizations, resulting in arterial injury in 0.1%-0.5% of patients. Routine performance of manometry during catheterization may successfully identify unintended arterial puncture and avoid arterial cannulation and injury. METHODS: We conducted a retrospective review of all cases of central venous catheter ...

Vascular access is called Achilles' heel of hemodialysis because it is associated with a substantial morbidity. A permanent vascular access is created either by a direct connection of the patient's own artery and vein or by the interposition of a graft. Arteriolar beds are bypassed, which leads to a substantial ...

Central venous catheterization is a critical component of management for the critically ill patient in the operating room and intensive care unit. When using ultrasound techniques for central venous access, access is achieved with fewer attempts, a reduced incidence of carotid artery punctures or 'hits', an increased success rate, and ...

Central venous access devices are extensively used for long-term chemotherapy and parenteral nutrition. However, there are some possible immediate, early, and late complications related to the implantation technique, care, and maintenance. We present the uncommon occurrence of a thrombosis of the internal jugular vein due to a spontaneous migration of ...

Catheter occlusion and thrombosis are common problems associated with central venous catheters, peripherally inserted central catheters, and peripheral intravenous catheters. A prospective study was performed at a community hospital to determine whether an antireflux valve device would reduce the frequency of complications in these catheters and safely allow the elimination ...

Herein, we describe a technique that facilitates percutaneous vascular access when the traditional method of achieving access is unsuccessful. For multiple reasons, gaining access to small vessels in pediatric patients is sometimes difficult. In instances of atrial, ventricular, or great arterial communications, a wire can be positioned from a vein ...

Catheter type, access technique, and the catheter position should be selected considering to the anticipated duration of PN aiming at the lowest complication risks (infectious and non-infectious). Long-term (>7-10 days) parenteral nutrition (PN) requires central venous access whereas for PN <3 weeks percutaneously inserted catheters and for PN >3 weeks ...

Bilateral total knee replacement (BTKR) has been associated with a higher incidence of fat embolism (FES) compared to single knee replacement. Consequently, intraoperative monitoring with a pulmonary artery catheter (PAC) has been recommended. This study compares clinical outcome in BTKR patients monitored with central venous pressure versus PAC. A retrospective ...

An 8-week-old preterm boy experienced respiratory deterioration due to unilateral pleural effusion. Intra-abdominal extravasation of parenteral fluid with leakage into the pleural cavity was suspected based on biochemical analysis of the effluent. Perforation of the central venous catheter in the peritoneal cavity was subsequently confirmed by contrast roentgenography. As in ...

The purpose of this review is to explore the pathophysiology, epidemiology, and interventional treatment of central vein stenosis (CVS) that may result from central vein catheter (CVC) placement. The precise mechanism of CVC-associated CVS remains largely undefined, though anatomic considerations appear to play a prominent pathologic role. The impact of ...

Over 70% of patients initiating chronic hemodialysis in the United States have a tunneled central venous catheter (CVC) for dialysis as their first blood access device. Tunneled CVC have requirements that are unparalleled by other access devices: high blood flow rates at moderate pressure drops without obstruction, minimal trauma to ...

Venous accesses for hemodialysis are beset with thrombosis and stenosis, often resulting in loss of central venous access. We report a case in which an alternate access was created by placement of hemodialysis catheter into the central vasculature by penetrating a stent previously placed in the stenosed right brachio-cephalic vein. ...

BACKGROUND: Some children requiring chemotherapy, total parenteral nutrition, or repeated blood sampling for long periods have no more axillary, internal jugular, external jugular, saphenous, or femoral veins available for cannulation. In such patients, the central venous system can still be accessed via alternate routes e.g. the azygos vein, the gonadal ...

Percutaneous catheterization is a frequently-used technique to gain access to the central venous circulation. Inadvertent arterial puncture is often without consequence, but can lead to devastating complications if it goes unrecognized and a large-bore dilator or catheter is inserted. The present study reviews our experience with these complications and the ...

Central venous catheterization is associated with a wide spectrum of vascular complications, including inadvertent arterial puncture. We describe 2 cases of successful open surgical repair of iatrogenic cervicothoracic arterial injuries secondary to central venous catheterization. In both patients, a novel transmanubrial approach was incorporated to expose and control the brachiocephalic ...

BACKGROUND: The Groshong catheter (GC) is commonly used as a peripherally inserted central catheter (PICC), and the external jugular vein (EJV) is not a common route for central venous access (CVA). Therefore, external jugular venous catheterization (EJVC) using a GC is rare. However, our experience has shown that this procedure ...

Intravenous prostanoids are the backbone of therapy for advanced pulmonary arterial hypertension (PAH) and have improved long-term outcome and quality of life. Currently, two prostanoids are approved by the US Food and Drug administration for parenteral administration: epoprostenol (Flolan) and treprostinil (Remodulin). Chronic intravenous therapy presents considerable challenges for patients ...

Although rare, misplacement of central venous catheters in supra-aortic arteries is potentially fatal. Five patients had safe catheters removal using percutaneous closure devices. Three patients were coagulopathic, 3 under intensive care and 1 in immediate postoperative limb amputation. Patients were treated successfully, with immediate hemostasis and without complications in a ...

We explore six classes of fractal probability laws defined on the positive half-line: Weibull, Frechét, Lévy, hyper Pareto, hyper beta, and hyper shot noise. Each of these classes admits a unique statistical power-law structure, and is uniquely associated with a certain operation of renormalization. All six classes turn out to ...

Venous hypertension due to proximal central venous outflow obstruction coexisting with a functioning arteriovenous fistula in the ipsilateral arm presents with a complex management problem in hemodialysis patients. Ligation of the arteriovenous communication is the simplest procedure to relieve symptoms; however, this sacrifices the patient's hemodialysis access, which may be ...

OBJECTIVES: Results of Fontan's procedure have improved considerably, but perioperative mortality still occurs, attributed to ventricular dysfunction, stroke, arrhythmia, thromboembolism, and multi-organ dysfunction. Our protocols of operative and intensive care unit management address these potential issues, and have been associated with zero mortality, even with many high-risk candidates. METHODS: From ...

Establishing and maintaining venous access forms an increasing proportion of the workload in interventional radiology. Several patient groups require medium-term to long-term venous catheters for a variety of purposes, including chemotherapy, long-term antimicrobials, parenteral nutrition, short-term access for haemodialysis or exhausted haemodialysis. Often, these catheters are required for treatment and ...

Traumatic pneumatoceles appear rarely after pulmonary parenchymal or bronchial disruption. Treatment is usually expectant with intervention reserved for complications, such as infection, expansion, or cardiopulmonary deterioration. A 17-day-old female was transferred to our NICU with a left-sided pneumatocele resulting from an intraparenchymal chest tube insertion. She was born at 30 ...

Mechanical circulatory support has evolved markedly over recent years. ECMO (extra corporeal membrane oxygenation) is instituted for the management of life threatening pulmonary or cardiac failure (or both), when no other form of treatment has been or is likely to be successful. Most commonly, it is instituted in an emergency ...
