BACKGROUND Because of long-term use for chemotherapy and fluid administration in cancer patients, a totally implantable venous access port (TIVAP) has been advised as a feasible catheter. The purpose of this study was to evaluate the effectiveness and safety of ultrasound (US)-guided internal jugular vein (IJV) puncture for TIVAP implantation in patients with breast cancer. METHODS We reviewe...

BACKGROUND The aim of our study was revised as follows: to clarify the postoperative complications of multifunctional central venous ports and the risk factors for such complications to promote the safe use of the PowerPort system in the hospital. METHODS The study group comprised 132 patients in whom implantable central venous access ports (PowerPortⓇ) were placed in our hospital from March ...

PURPOSE To present our results after short-term (1 month) intra-arterial infusion therapy of PGE₁-alprostadil via a port system implanted in the ipsilateral external iliac artery (EIA) in patients with severe rest pain. METHODS Ten patients with severe rest pain were included. All patients showed extensive peripheral vascular disease below the knee. The tip of the catheter was introduced via ...

PURPOSE A multidisciplinary approach to the treatment of patients with malignant diseases requires adequate venous access in order to safely administer chemotherapy, blood transfusion and blood products, antibiotics, rehydratation and total parenteral nutrition. The insertion of the central venous catheter (CVC), its use and its maintenance can be accompanied by multiple complications. METHOD...

Vascular cutdown and echo guide puncture methods have its own limitations under certain conditions. There was no available algorithm for choosing entry vessel. A standard algorithm was introduced to help choose the entry vessel location according to our clinical experience and review of the literature. The goal of this study is to analyze the treatment results of the standard algorithm used to ...

Operant behavioral tasks for animals have long been used to probe the function of multiple brain regions (i.e., understanding the role of dopamine in electrical brain stimulation reward [1], or determining the rewarding properties of feeding oriented brain pathways [2]). The recent development of tools and techniques has opened the door to refine the answer to these same questions with a much h...

OBJECTIVE To determine the complications of venous access devices (VADs) in cancer patients. SETTING Retrospective study in a tertiary referral center with specialist hematology and oncology services. SUBJECTS First one hundred consecutive patients who were implanted a VAD. All patients had an underlying cancer and the devices were inserted by the same surgeon. The duration of use of VADs a...

this research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and nox in di diesel engines. since the most important engine design parameters, includi...

Three type I diabetic patients nonresponsive to subcutaneous insulin were implanted with a subcutaneous peritoneal access device. In these patients, multiple subcutaneous injections had been unable to prevent recurrent hospital admissions for diabetic ketoacidosis. The patients were responsive to intravenous insulin but had limited accessible peripheral veins. Complications of thrombosis and/or...
