Aneurisma idiopático de artéria ilíaca comum direita em criança de três anos - relato de caso / Idiopathic right common iliac artery aneurysm in a three-year-old child - case report

Resumo A incidência de aneurismas ilíacos em crianças não é conhecida, havendo apenas alguns relatos de casos na literatura sobre o tema. Neste estudo, é relatado o caso de um paciente masculino, 3 anos, com aneurisma sacular isolado na bifurcação da artéria ilíaca comum direita de origem idiopática, que foi submetido a ressecção, ligadura da artéria ilíaca interna e anastomose vascular término-terminal. Após 1 mês de seguimento, foi diagnosticada oclusão assintomática da anastomose. Devido à presença de circulação colateral, não houve repercussões clínicas da oclusão, e a criança apresentou evolução clínica favorável a médio prazo.

Abstract The incidence of iliac aneurysms in children is unknown and there are only a small number of case reports in the literature on the subject. This article describes the case of a 3-year-old male patient with an isolated saccular aneurysm at the bifurcation of the right common iliac artery, of idiopathic origin, which was repaired by resection, ligature of the internal iliac artery and end-to-end vascular anastomosis. After 1 month of follow-up, he was diagnosed with asymptomatic occlusion of the anastomosis. The occlusion had no clinical repercussions because of collateral circulation and the child has had a favorable clinical course over the medium term.

Unusual Giant Mycotic Aneurysm at the Middle Cerebral Artery: Case Report / 대한뇌혈관학회지

Aneurysms at the distal branch of the middle cerebral artery may be mycotic or congenital in origin. A 34 year-old male patient was admitted with a seizure and a 7-day history of upper respiratory tract infection. The neurological examination showed no abnormality except for headache and mild dysarthria. There was no intracardiac lesion suggesting infective endocarditis. CT, MRI and cerebral angiograms revealed a partially thrombosed giant aneurysm at the distal branch of the middle cerebral artery. Pathologic examination revealed acute inflammatory cells and focal necrosis in the aneurysmal wall as well as recent thrombus. Here, we are reporting an unusual case with a giant distal middle cerebral artery aneurysm with intramural inflammation, suggesting a congenital giant aneurysm with secondary infectious inflammation.
