title: A retained neurointerventional microcatheter fragment in the anterior communicating artery aneurysm in multi-slice computed tomography angiography.
abstract: We present a case of multi-slice computed tomography angiography of a 60-year-old patient with a retained fragment of microcatheter within an anterior communicating artery (AcomA) aneurysm. This is a rare complication of Guglielmi detachable coil embolization. After an unsuccessful embolization procedure, the patient underwent surgery. During clipping of an AcomA aneurysm, the microcatheter traveled up the pericallosal branch of the right anterior cerebral artery. Subsequently, the microcatheter fragment did not prevent normal blood flow through the artery, and the patient has been doing well without neurological sequelae.
