Magnetic resonance angiography (MRA) is supposed to be the new 'gold standard' in the diagnosis of atherosclerotic disease of the extracranial arteries. A case report is presented on a patient in whom discordant findings of the status of the left internal carotid artery (ICA) were identified in color-coded duplex-sonography and ...

Venous blood gas (VBG) analysis is a safer procedure than arterial blood gas (ABG) analysis and may be an alternative for determining acid-base status. The objective of this study was to examine the agreement between ABG and central VBG samples for all commonly used parameters in a medical intensive care ...

Cardiovascular health has traditionally been monitored by peripheral measurements of brachial blood pressure. Although these measurements have proven to be of good diagnostic and prognostic value, novel technology now allows us to non-invasively and easily obtain measurements of more central arteries, specifically stiffness of the central aorta. The purpose of ...

Central venous catheterisation and arterial catheterisation are common procedures performed by anaesthetists. Traditionally, the technique of locating surface landmarks and palpation was used to assist in vascular access. The introduction of perioperative ultrasonography in the past decade has dramatically changed this procedure. In the United States and United Kingdom, guidelines ...

OBJECTIVE: Accidental arterial cannulation during ultrasound-guided central venous cannulation is rarely reported and should be much less likely with dynamic guidance. Although accidental arterial penetration with the needle may occur periodically without notice and with little harm, actual arterial dilation and line placement may result in serious complications. METHODS: This ...

An 83-year-old woman with end-stage renal disease secondary to hypertension and left upper-arm arteriovenous graft dysfunction was found to have fibromuscular dysplasia (FMD) of the left brachial artery. The classic "string of beads" appearance on arteriography was suggestive of FMD. The lesion responded well to balloon angioplasty and required no ...

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 ...

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. ...
Saleh H M - - 2008
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 ...

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 ...
Alqahtani Aayed R - - 2008
BACKGROUND: In children who require prolonged and multiple venous catheterizations, the superior vena cava and iliofemoral veins may become occluded, making central venous access a difficult challenge. We report an innovative technique of catheter insertion percutaneously from the neck into the right atrium traversing a thrombosed superior vena cava using ...

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 ...
