Deep Vein Thrombosis after Cement Intravasation during Hip Hemiarthroplasty
Cement intravasation; Deep vein thrombosis; Embolism; Hemiarthroplasty
© 2020 The Authors Cement intravasation occurs in hemiarthroplasty when pressurization of cement through the medullary canal backflows through the nutrient vessels. This case report describes a 70-year-old woman who underwent hip hemiarthroplasty for a displaced left femoral neck fracture. Postoperative radiographs demonstrated radio-opacity consistent with local cement intravasation. A Doppler ultrasound study subsequently revealed a mobile thrombus at the confluence of the femoral and profunda femoris veins, as well as a nonmobile thrombus within the profunda femoris vein. The more proximal thrombus was determined to be cement that had intravasated during the index operation. The cement likely impeded venous flow, ultimately leading to the development of deep vein thrombosis just distal to the site of cement occlusion.
