ABSTRACT
OBJECTIVES:
Intercostal artery aneurysm (IAA) is a very rare condition. Interestingly, only one study reported a case of intercostal aneurysm caused by an arteriovenous fistula (AVF). Here, we report the case of a patient with non-ruptured isolated giant true IAA caused by an AVF (size, 28 × 41 mm).METHODS:
Treatment options for IAA include open surgery and endovascular treatment (EVT). We chose EVT, as it is minimally invasive. The right 11th intercostal artery and aneurysm diverged from the aorta. Two outflow arteries, one inflow artery, and an AVF from the aneurysm were confirmed, and coil embolization was performed. The artery of Adamkiewicz did not communicate with the right 11th intercostal artery. We performed angiography and confirmed occlusion of IAA with endoleak.RESULTS:
There were no clinical findings indicative of spinal cord infarction after treatment. The patient did not develop complications and was discharged the day after treatment. Endoleak was not observed on computed tomography angiography findings at 1 month after treatment.CONCLUSIONS:
In our patient, an AVF might have caused IAA. Endovascular treatment for non-ruptured isolated giant IAA is a safe and minimally-invasive treatment. We found that performing EVT is beneficial when the size of the IAA exceeds 30 mm.Palavras-chave
