Kostantinos Mallas, the partner in charge of the personal injury department and senior trial attorney, proved that the defendant committed malpractice by failing to provide blood thinners to his patient who injured her knee on Christmas day in 2009. The defendants argued that the medical standard did not indicate the need for blood thinners in this instance. Through expert testimony, Mr. Mallas was able to convince the jury that it was a deviation from good an accepted medical practice not to prescribe blood thinners. The decedent ultimately developed a deep vein thrombosis (blood clot) which led to a pulmonary embolism, causing her death on January 20, 2010.
