title: Use of rheolytic thrombectomy in the treatment of feline distal aortic thromboembolism.
abstract: The purpose of this prospective clinical trial was to evaluate the safety and efficacy of a commercially available rheolytic thrombectomy system in the treatment of naturally occurring feline aortic thromboembolic disease. All 6 cats enrolled in the investigation were affected at the level of the distal aorta and had signs of the disease affecting both pelvic limbs. Cats were anesthetized and an arteriotomy was performed on 1 carotid artery to gain access to the arterial system. Selective arterial angiography was used to confirm the presence of thromboembolic disease. The thrombectomy system was advanced to the level of the thrombus using fluoroscopic guidance. Repeat angiography was used intermittently to assess progress of thromboembolus dissolution throughout the procedure. The use of the rheolytic thrombectomy system resulted in successful thrombus dissolution in 5 of 6 cats. Three of 6 cats survived to discharge. Both of these results compare favorably with conventional therapies used in the treatment of this disease. Feline distal aortic thromboembolism is a frustrating disease that warrants a guarded to poor prognosis. Rheolytic thrombectomy may provide veterinarians with an alternative therapy in the treatment of thromboembolic diseases, including feline distal aortic thromboembolism.
