Physiology






Etiology



• PTE is a secondary condition that occurs in association with diseases that cause blood stasis, alter endothelial integrity, or increase coagulability. PTE has been linked most commonly with immune-mediated hemolytic anemia, neoplasia, sepsis, protein losing nephropathy, cardiac disease, and hyperadrenocorticism (Box 9-2). Clinically silent pulmonary embolism occurs in a majority of dogs (82%) undergoing total hip replacement surgery. Small pulmonary thromboemboli are rapidly lysed and removed by the local fibrinolytic system; however, occlusion of larger pulmonary arteries or massive showering of emboli to a large circulatory volume can lead to acute right ventricular overload.
