bulletTen-year-old intact female Maine coon cat ("Newman")

Presenting Complaints

bulletHistory of systemic thromboembolism

Pertinent History

bulletNewman was referred to the VMTH Emergency Service three days ago after his veterinarian diagnosed a partial saddle aortic thromboembolus. Three days ago he was knuckling his right hind leg and dragging it. The right caudal foot was cool and the femoral pulse was weak in this leg. He is back for a recheck examination today. The client says the foot has now warmed up and Newman is walking better, although his right hind leg has been stiff.
bulletA murmur was first noted 3 months ago by a veterinarian in Pennsylvania.
bulletNewman has seemed less active for the last couple of weeks. He has panted when stressed (at veterinarian's office; after bath) for a long time. He has never been seen panting after exercise. No coughing.
bulletNo other known problems. No surgery since neuter. Vaccinated for travel in April.
bulletTRAVEL: Newman has lived in Portland and Spokane. He has been in Philadelphia for the last four years and recently moved to Fairfield, CA.
bulletENVIRONMENT: He lives with one other cat (Newman's brother) and one dog - both healthy. Cats are mostly outdoors.
bulletDIET: Science Diet hairball adult. Recently some wet food.
bulletNo C/S/V/D/PU/PD.
