Symptomatic bilateral pulmonary embolism without deep venous thrombosis in an adolescent following arthroscopic anterior cruciate ligament reconstruction: a case report and review of the literature

Abstract

Abstract Background Venous thromboembolism, specifically pulmonary embolism, is a rare complication following elective pediatric orthopedic surgery. Bilateral pulmonary embolism with associated pulmonary hemorrhage/infarct without concomitant deep vein thrombosis has never been reported following routine anterior cruciate ligament reconstruction in an adolescent.

Case presentation A 16-year-old white girl presented with acute onset shortness of breath and pleuritic chest pain 6 days following elective anterior cruciate ligament reconstruction. After performing a thorough work-up, she was diagnosed as having provoked bilateral pulmonary embolism with associated pulmonary hemorrhage without concomitant deep vein thrombosis. She was treated successfully with 3 months of anticoagulation therapy with daily Lovenox (enoxaparin) injections.

Conclusions Symptomatic bilateral pulmonary embolism may have a good prognosis if it is diagnosed early and treated appropriately. It is important to appreciate the risk of provoked thromboembolic events in healthy adolescents undergoing arthroscopic knee surgery.
