Shortly after joining Kline & Specter in January 2001, Dr. Aussprung worked with Tom Kline in the Matteo case, a complex case that involved the death of Suzanne Wester Matteo, who suffered internal bleeding following a routine medical procedure. Her doctors did not notice the bleeding nor did they act to help her. Suzanne’s husband, Tony Matteo, performed emergency surgery and saved his wife’s life, but days later she suffered respiratory arrest. Tony Matteo sued his late wife’s doctors and a jury returned a $25 million verdict in his favor. In March 2006, Dr. Aussprung was co-counsel in a case in which a woman died after an elective bowel resection due to a bowel perforation and sepsis because her surgeon failed to timely diagnose the problem. The trial resulted in a jury verdict of nearly $2.7 million, which was the largest verdict ever in a death case in Lackawanna County. (See the Hook case.) Dr. Aussprung has handled a multitude of medical malpractice suits with Kline & Specter, many of them resulting in substantial settlements. In two cases against Children's Hospital of Philadelphia, settlements were reached in suits in which children died, one a five-year-old boy who was over-transfused during a surgery and the other a two-month-old infant whose infection following surgery was never properly diagnosed. Among Dr. Aussprung’s other cases that produced substantial settlements was that of a teenager who had been severely brain injured at three years of age when his diabetes mellitus was not properly managed. In yet another case, he helped win a settlement for a baby who was brain injured after getting improper care during delivery by a nurse midwife.
