Peripheral venous catheterization is a frequently required basic procedure in hospital care. However, scientific consideration of the keys for successful catheterization has been inadequate. According to previous reports, the general success rate of peripheral venous catheterization is 74% to 88% [1]. Two nonrandomized controlled trials have implied that the larger the veins are, the easier the...

PURPOSE To develop a clinically relevant porcine model for the study of hepatic metabolism of drugs by means of hepatic vein catheterization. MATERIALS AND METHODS review of literature and elaboration of a hypothesis, design of an experimental method. RESULTS recent clinical studies were conducted by withdrawing cirrhotic patients' blood from right hepatic vein during hepatic vein pressure ...

2014 Right heart catheterization using peripheral venous access is an approach initially used by pioneers of cardiovascular exploration, but subsequently almost forgotten with the popularization of direct puncture techniques of central veins for diagnostic, monitoring and therapeutic needs. Improved equipment and the recognition of the complications of direct central (femoral) artery puncture r...

BACKGROUND Transpedal access is increasingly utilized for peripheral vascular catheterization. There is a paucity of data on the use of radial hemostasis devices as an alternative to manual compression for achievement of hemostasis after this approach. OBJECTIVE To compare safety and efficacy of two hemostasis devices following transpedal catheterization for lower extremity revascularization ...

Risk factors for candidemia were analyzed in a case-control study of 30 cancer patients with candidemia and 58 controls. In a univariate analysis, previous surgery, neutropenia, central catheterization, chemotherapy, specific antibiotic treatments, and peripheral cultures positive for Candida spp. were associated with a significantly increased risk of candidemia. In a multivariate logistic mode...

Post-catheterization pseudoaneurysm is most common vascular complications of cardiac and peripheral angiographic procedures. We report a 67-year-old female patient with giant (25 cmx25 cm) femoral artery pseudoaneurysm which gradually enlarged without rupture developed after catheterization in the periods of three years. She electively underwent to operation. Pseudoaneurysm pouch was evacuated ...

SINCE the description by Mbller' in 1953 of stenosis of peripheral pulmonary arteries, this congenital lesion has been recognized with increasing frequency. The lesion is of interest both from a clinical and physiologic standpoint. From the latter standpoint, there is sufficient documentation to warrant the inclusion of this congenital anomaly as one of the causes of right ventricular hypertens...

Introduction: Peripheral Intravenous catheterization is the most commonly used invasive treatment method in patients admitted to the hospitals, but it has some complications. The indwell time of catheter is one of the factors associated with the occurrence of complications, especially phlebitis. In spite of the instructions for replacing the catheters after 72 hours, sometimes the complications...

Peripheral MR Angiography is rapidly developing and becoming the standard method for evaluating peripheral vascular disease. MRA allows accurate and detailed assessment of peripheral vasculature without requiring arterial catheterization, nephrotoxic contrast, or ionizing radiation. Latest improvements in this area include time-resolved MR angiography, stepping table bolus chase 3D MR angiograp...
