The gross and histopathologic lesions observed in a case of spontaneous proximal aortic dissection (dissecting aortic aneurysm) in a mature ostrich are reported. At necropsy, a dissecting intramural hematoma was seen in the proximal aorta, extended about 12 cm distally from the aortic valves. Histopathologic changes in aortic dissection included fragmentation and disruption of elastic laminae, presence of cystic extracellular spaces, and pooling of ground substance in the tunica media. Hepatic copper levels were measured, and the low concentration found suggested that a copper deficiency together with other risk factors such as the elevation of blood pressure may have been implicated in the development of the aortic dissection seen in this ostrich.

La trombosis venosa superfi cial (TVS) de miembros inferiores venía considerándose como una patología de naturaleza benigna con un curso clínico autolimitado. Actualmente se conoce que sus potenciales complicaciones pueden ser graves o incluso mortales, como la trombosis venosa profunda o el tromboembolismo pulmonar. Existen diferentes formas de presentación clínica, factores de riesgo y diferentes tratamientos para su abordaje, principalmente en Atención Primaria.
