| Abstract: | Angiography in a horse was used to confirm a pseudoaneurysm of the dorsal metatarsal artery originating from trauma. Gradual clinical resolution of the pseudoaneurysm occurred within days following the procedure. A follow-up angiogram confirmed the clinical impression. An etiology of the spontaneous resolution is presented. Probable influences included technical factors of the injection procedure that caused prolonged presence of the contrast medium within the aneurysmal sac and factors that enhance thrombus formation during angiography. |
