Incidence of Pulmonary Embolism After Non‐Cemented Total Hip Arthroplasty in Eleven Dogs: Computed Tomographic Pulmonary Angiography and Pulmonary Perfusion Scintigraphy

Objective— To compare the incidence of pulmonary embolism (PE) in 11 dogs that had non-cemented total hip replacement (THR) to that reported in dogs after cemented THR. Study Design— Prospective clinical study. Animals— Large mixed breed dogs (n=11). Methods— Thoracic computed tomographic pulmonary angiography (CTA) was performed on all dogs pre- and postoperatively. Pulmonary perfusion scintigraphy was performed postoperatively. Results— PE was not identified on postoperative CTA or pulmonary perfusion scintigraphy. Conclusions— The incidence of PE after non-cemented THR in these 11 dogs, as evaluated with pulmonary perfusion scintigraphy and thoracic CTA was lower than reported in dogs undergoing cemented THR. Clinical Relevance— Based on the results of this study the incidence of PE as a complication of total hip arthroplasty is reduced when a non-cemented system is used.
