Defense verdict Secured on behalf of a major Philadelphia healthcare provider

Health Care Liability
February 20, 2026

We obtained a defense verdict on behalf of a major Philadelphia healthcare provider after a contentious six-day trial. After undergoing a kidney transplant, a patient suffered complications in post-operative care and died a day after the surgery. The plaintiffs were critical of the post-operative care, claiming the physicians failed to take the patient back to the operating room in light of post-op bleeding.
