Description: Resumo: De 726 caprinos necropsiados, dois (0,28%) apresentaram aneurisma na arteria aorta, sendo um macho com idade de 48 meses e uma femea com cerca de 30 meses. Os animais eram oriundos de um rebanho mantido em regime semi-extensivo com pastejo em caatinga nativa e pernoite em aprisco. Macroscopicamente observou-se palidez das mucosas externas e das visceras. Nas cavidades toracica e abdominal estavam presentes grandes coagulos resultantes da ruptura das partes afetadas das arterias. As lesoes das arterias aorta toracica e abdominal foram carcterizadas pela dilatacao das paredes formando estruturas saculares com presenca de inumeros coagulos e tecidos necroticos de aproximadamente 10cm a 20cm de comprimento. Histologicamente, observou-se a destruicao do tecido endotelial, necrose e infiltracao de leucocitos das camadas intima, media e muscular da arteria. Acredita-se que a causa primaria dos aneurismas detectados esteja relacionado com os processos inflamatorios presentes em outros orgaos. [Aneurism in the aorta artery in goats]. Abstract: Two (0.28%) of 726 necropsyed goats presented aneurism In the aorta artery, one being a male with 48 months and the other, a female about 30 months of age. The animais carne from a herd in semi-extensive regime, grazing in caatinga vegetation and spending the nights in appropriate pan. Paleness in external mucosa and viscera was observed macroscopically. Large coagula were presented in the thoracic and abdominal cavities, dueto ruptura ol the aneurismatic parts of the blood vessels. The lesions of thoracic and abdominal aortas were characterized by wali dilations forming saccular struc-tures, with presenco of many coagula and necrotic tissues of about 10cm to 20cm of length. Histo-logically, a destruetion In the endotelial tissues, nacrosis and infiltration of leucocytes in the intimate, median, and muscular Iayers were observed. It is believed that the primary cause of the aneurisms detected in this study would be related to teh inflamatory processes of other organs.
