BACKGROUND/AIM: The central area of the brain, including the pre- and post-central gyri with their vascular structures, is one of the most crucial regions to preserve in neurosurgical intervention. The central sulcus is also a landmark of utmost importance for neurosurgeons. Although the arteries supplying the central region have been ...

Central venous catheters are used in various hospital wards. An anterior-posterior chest X-ray is usually obtained soon after cannulation to assess the location of the catheter tip. This prospective clinical study was designed to determine the radiographic catheter tip position after central venous cannulation by various routes, to identify clinical ...

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 ...

Standard coronary venous angiography (SCVA) provides a static, fixed projection of the coronary venous (CV) tree. High-speed rotational coronary venous angiography (RCVA) is a novel method of mapping CV anatomy using dynamic, multiangle visualization. The purpose of this study was to assess the value of RCVA during cardiac resynchronization therapy. ...

The transpulmonary thermo-dye dilution technique enables assessment of cardiac index (CI) intrathoracic blood volume index (ITBVI) and extravascular lung water index (EVLWI). Since the extent of lung edema may influence the reliability of CI measurement by transpulmonary thermodilution due to loss of indicator, we analyzed the impact of EVLWI on ...

Liu and co-workers report on a preliminary study with formaldehyde-fixed arterial allografts. In this way they provide a novel alternative for solving the problem of failing to achieve vascular access in hemodialysis patients. Formaldehyde fixation offers an effective way of reducing the antigenicity of heterologous arterial allograft. Preliminary clinical experience ...

Vertigo is not an uncommon presentation to the emergency department. It is most commonly caused by benign peripheral processes, such as inner ear or vestibular nerve dysfunction, but can be due to central brain lesions. In this report, we present a central cause of isolated vertigo: brainstem infarct secondary to ...

The internal jugular vein (IJV) is an optimal location for obtaining central venous access due to its superficial location. However, there are many potential pitfalls of using the landmark technique, including aberrant anatomy of the IJV, proximity to the carotid artery and cupola of the lung, body habitus, and prior ...

The placement of central venous catheter (CVC) through internal jugular vein is not free from potential hazards. We report two cases of triple lumen central venous catheter, placed into right internal jugular vein, which got entrapped in patients who had undergone mitral valve replacement. The entrapment of catheter went unnoticed ...

A 45-year-old man presented with atypical central chest pain and ST-T changes on electrocardiogram. Repeated arterial blood gas examinations were unremarkable and portable echocardiography demonstrated mildly dilated right atrium and ventricle. Initial treatment for acute coronary syndrome was initiated, as there was evidence of myocardial necrosis on blood examination. However, ...

INTRODUCTION AND AIMS: The Subclavian vein has been traditionally the vein of choice for central venous catheterization by general surgeons. Alternative settings for the introduction of totally implantable venous access devices (TIVAD) and the search for lower rates of morbidity led to the choice of other central veins. This study ...
KOYAMA, Yu
The purpose of this study was to evaluate the safety and usefulness of a peripheral vein approach when inserting a central venous catheter (CVC) as compared with a subclavian vein approach (infraclavicular approach). During the period April-July, 1998,a total of 51 patients (41 male, 10 female) underwent the insertion of ...

Patients on long-term hemodialysis undergo multiple interventions, including insertion of central catheters and arteriovenous anastomoses for creation of vascular access. The need for high-flow vessels to maintain hemodialysis efficiency leads to wear on the central veins and consequent stenosis and occlusion. In addition to local signs of impaired venous drainage, ...

Physicians spend a considerable amount of time and effort inserting catheters and needles into patients. Central venous catheters are the mainstay of measuring hemodynamic variables that cannot be assessed by noninvasive procedures. These catheters also allow hemodialysis, parenteral nutritional support, delivery of medications, and catecholamine administration. Arterial pressure catheters are ...

BACKGROUND: Although there are many studies about central venous catheter-related infection, we have not found any analysis of the incidence of internal jugular venous catheter-related bacteremia associated with different accesses. OBJECTIVE: The objective of this study was to test whether the position of the internal jugular venous catheter, central or ...

The right internal jugular vein is widely accepted as the vessel of choice for placement of long-term central venous catheters for hemodialysis. As vascular access sites become progressively depleted, alternate anatomic locations for access must be sought. We describe a non-surgical (fluoroscopy assisted, percutaneous) technique for placement of external jugular, ...

Removal of unwanted intravascular foreign body is a useful but infrequent procedure carried out by interventional radiologists. We study a patient who had a long guidewire left in her body following central venous catheter placement by a surgeon. The guidewire was later found in situ, with both intravascular and extravascular ...

Outpatient parenteral antibiotic therapy is routinely used in pediatrics, but few data are available on catheter-associated complications and survival times. Catheter-associated complications, defined as mechanical or nonmechanical, and survival times in peripherally inserted central catheters and central venous catheters used for outpatient parenteral antibiotic therapy in childhood were compared. The ...

The management of a blocked long-term central venous catheter has traditionally been removal and re-siting, even when device failure is not associated with venous thrombosis or sepsis. It is not possible to 'railroad' a split dual-lumen central venous catheter down a long tortuous s.c. tunnel. Our exchange technique was designed ...

PURPOSE: Cardiovascular catheterization can be challenging whenever a stenosis or an abnormal vascular course interferes with probing the target vessel. This study addresses the feasibility of navigating a guide wire with a magnetic tip by an external magnetic field through pulmonary and systemic arteries in an experimental porcine model. MATERIALS ...

Central vein stenosis is commonly associated with placement of central venous catheters and devices. Central vein stenosis can jeopardize the future of arteriovenous fistula and arteriovenous graft in the ipsilateral extremity. Occurrence of central vein stenosis in association with indwelling intravascular devices including short-term, small-diameter catheters such as peripherally inserted ...

There are several very obvious and simple solutions for eliminating the "Pitfalls" and for minimizing the risk of occurrence of any perioperative complications associated with placement of chronic indwelling central venous access devices in cancer patients. The first is the utilization of a venous cutdown approach, such as the cephalic ...

The largest prospective cadaver study done over a 3-year period to investigate the arterial variations of the forehead is presented. The primary goal was to find anatomical support for various forehead flaps previously designed. Thirty cadaver foreheads (60 hemi-foreheads) were dissected from deep to superficial to identify arterial variations. The ...

The authors analyzed 309 central venous catheters (CVC) inserted in 147 hemodialysis patients before the maturation of the first or new arteriovenous fistula. One clinical manifestations of sepsis after CVC insertion was found. In all, 33.7% of the catheters were removed because of early minor complications: CVC occlusion, inadequate blood ...

Central venous stenosis is a frequent complication in hemodialysis patients, which can manifest clinically with ipsilateral upper extremity edema. When symptomatic, it is usually treated by percutaneous transluminal angioplasty. When angioplasty is unsuccessful, stent deployment is a therapeutic option. The goal of the present study was to evaluate the primary ...
