Infectious intracranial aneurysms (IIA) or mycotic aneurysms (translator's note: the aneurysm was originally reported to be shaped like a fungal colony, hence the name) is the cause of infective endocarditis One of the neurological complications
.
They are due to the migration of septic emboli from the heart into the arteries, thereby forming IIAs

The location of IIA endovascular therapy (EVT) and the delay of EVT compared with cardiac surgery remain controversial
.
In the absence of randomized studies, EVT regimens for IIAs depend on the experience of the treatment team
In February 2022, Alexis Gudon et al.
from France published their findings in Neuroradiology, reporting a retrospective single-center series of patients with IIA who received EVT

The study included patients from January 2009 to July 2020

62 IIAs (30 ruptures) were diagnosed in 31 patients
.
Fifty-six cases of IIA were diagnosed in the first DSA, and 6 cases of IIA were diagnosed in early control exploration
The authors concluded that IIA occlusion of the parent artery during EVT is effective in preventing rupture without significant neurologic risk
