RESUMO
Aneurysms of the splenic artery are the third most common type of intra-abdominal aneurysms and the most common type of visceral aneurysms. Portal hypertension is a significant risk factor for development of these aneurysms. We report the case of a white, female, 52-year-old patient with multiple splenic artery aneurysms and hypersplenism secondary to portal hypertension and cirrhosis. Abdominal angiotomography identified six splenic aneurysms. In this scenario, an endovascular intervention was scheduled to conduct embolization using controlled release coils and Onyx™ embolization agent. The three largest aneurysms were treated. Control angiographs showed good exclusion of the aneurysms. The endovascular technique therefore proved to be a good choice considering the patient's comorbidities and blood disorders. In this case, the procedure was successful. There were no immediate or long-term complications. The patient recovered well and is in clinical follow-up.
RESUMO
Resumo Os aneurismas de artéria esplênica são o terceiro tipo mais comum de aneurismas intra-abdominais, sendo considerados o tipo mais comum de aneurismas viscerais. A hipertensão portal é um fator de risco significativo para o seu desenvolvimento. Relatamos o caso de uma paciente do sexo feminino, branca, de 52 anos, com múltiplos aneurismas de artéria esplênica com hiperesplenismo por hipertensão portal e cirrose. Por meio da angiotomografia abdominal, foram identificados seis aneurismas esplênicos. Nesse contexto, optou-se por intervenção endovascular por meio da embolização com molas de destaque controlado e material embolizante Onyx™. Os três aneurismas maiores foram tratados. As angiografias de controle mostraram boa exclusão dos aneurismas. Portanto, a técnica endovascular foi uma boa opção devido às comorbidades e às discrasias sanguíneas apresentadas. Neste caso, o procedimento foi bem-sucedido. Não houve intercorrências imediatas ou complicações a longo prazo. A paciente evoluiu bem, seguindo em acompanhamento clínico.
