Background Aortic and aortoiliac thrombosis in dogs causes disease and death. Objective To describe the procedure and outcomes for stenting the caudal aorta and aortoiliac trifurcation. Animals Seven client‐owned dogs that underwent aortic/aortoiliac stenting for treatment of thrombosis. Methods Retrospective multi‐center investigation. Medical records were reviewed for dogs that underwent stenting of the aorta or aortoiliac trifurcation between 2008 and 2020. Information collected included history, signalment, clinicopathologic data, diagnostic imaging, procedure reports, and outcomes. Results Seven dogs with an occlusive thrombus located at or near the aortic trifurcation were included. Four of 7 dogs were non‐ambulatory. Hind limbs were paretic in 5 dogs, paralyzed in 1 dog, and claudication alone was noted in 1 dog. Five of the 7 dogs had protein‐losing nephropathy (PLN). Of 5 dogs with PLN, 1 had protein‐losing enteropathy (PLE) and controlled hypothyroidism and 1 had caudal aortic chondrosarcoma. Two dogs had no identified underlying disease. Angiography was performed before catheter directed thrombolysis and stent placement. No deaths occurred during the procedure. Postoperative complications included pain (4/7), bruising and edema (3/7), bruising only (1/7), and edema only (1/7). Median survival time (MST) of the 7 dogs was 264 days (range, 1‐1053 days). Five of 7 dogs were ambulatory within 2 days of stenting and survived to discharge with a MST of 425 days (range, 208‐1053 days). Conclusions and Clinical Importance Stenting of the aorta and aortoiliac trifurcation can provide an apparently safe and effective treatment with rapid return to ambulation for some dogs with aortic thrombosis.

“…The PFO acts as a “pop‐off” valve for the high‐pressure caudal right atrial chamber. However, the presence of right‐to‐left shunting between the caudal right atrial chamber and the left atrium may determine subsequent hypoxemia, which was suspected to be responsible for our patient's exercise intolerance and syncope …”

“…Cor triatriatum dexter is a relatively rare congenital condition in dogs, in which persistence of the right sinus venosus valve causes partitioning of the right atrium into cranial and caudal chambers . The fibro‐membranous partition commonly is perforated, but also can be imperforate with no communication between the right atrial chambers, as in our case . In dogs, several concurrent cardiovascular abnormalities have been described with CTD …”

A 2‐year‐old American Pit Bull dog was presented for surgical evaluation of imperforate cor triatriatum dexter (CTD) and patent foramen ovale (PFO). Echocardiography identified an imperforate CTD associated with a right‐to‐left shunting PFO and valvular pulmonary stenosis. A 2‐step interventional and surgical approach was used. Initially, a pulmonary balloon valvuloplasty was performed, and subsequently the dog underwent a surgical correction of the atrial anomaly under cardiopulmonary bypass.
