Hoi, ik kwam dit tegen op t web, terwijl ik voor een vriendin iets aan het zoeken was over kapotte kleppen in lies en knie na trombose. Percutaneously implanted artificial venous valves were first attempted in animal models, with various degrees of success. The small-intestinal submucosa square-stent bicuspid venous valve—the Portland valve—has given very promising results.27 Long-term results of the valve implanted in the sheep’s internal jugular resulted in 88% success as the valves maintained good function after 6 months.28 Malfunction of the remaining valves (12%) was due to valve tilting; 4% had thrombi in the tilted valve. A second-generation valve consisting of a square stent submucosa attached to a second square stent (DS BVV) or Z-stent was then developed (Figure 5). No tilting was seen at 6 weeks and angiographic competency was over 90%. http://www.phlebolymphology.org/2009/07 ... -syndrome/ |
