percutaneous retrieval of an intracardiac central venous port fragment using snare with triple loops
peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...
BACKGROUND Central venous access is extensively used in oncology, though practical information from randomized trials on the most convenient insertion modality and site is unavailable. METHODS Four hundred and three patients eligible for receiving i.v. chemotherapy for solid tumors were randomly assigned to implantation of a single type of port (Bard Port, Bard Inc., Salt Lake City, UT), thro...
An entry vessel is crucial for intravenous port implantation. A safe alternative entry vessel that can be easily explored is crucial for patients without feasible cephalic vein or for those who need port reimplantation because of disease relapse. In this study, we tried to analyze the safety and feasibility of catheter implantation via the deltoid branch of the thoracoacromial vein. From March ...
evidence acquisition a systematic literature searching of databases medline, embase, and google scholar was done from 1982 and updated in december 2015. search terms were “cholecystectomy”, “laparoscopic cholecystectomy”, “four port laparoscopic cholecystectomy”, “single-incision laparoscopic surgery”. context laparoscopic approach with its several techniques has become the standard method for ...
A SpaceWire network comprises SpaceWire links, nodes and routers. The nodes are the functional units that wish to use the onboard communication services of the SpaceWire network and are fitted with one or more SpaceWire interfaces. These units are connected together directly using point-to-point SpaceWire links or indirectly via SpaceWire routers. SpaceWire interfaces, links and routers are the...
Few FPGAs support creation of partially reconfigurable systems when compared to traditional systems based on total reconfiguration. This allows dynamic change of the functionalities hosted on the device when needed and while the rest of the system continues its working. Runtime partial reconfiguration of FPGA is an attractive feature which offers countless benefits across multiple industries. X...
The ability to understand and predict the expected internal behaviour of a given solid-propellant rocket motor under transient conditions is important. Research towards predicting and quantifying undesirable transient axial combustion instability symptoms necessitates a comprehensive numerical model for internal ballistic simulation under dynamic flow and combustion conditions. A numerical mode...
