This complaint is from a literature source.The following complications were reported in this publication: it was reported that 1 patient underwent coiling of an unruptured aneurysm and the procedure was complicated by severe vasospasms in the supraclinoidal segment of the left internal carotid artery (ica).The patient was treated with 1 mg of intra-arterial nimotop.Furthermore, following the elective endovascular coiling of a left internal carotid artery aneurysm an mri revealed acute punctate cortical infarctions, and she was treated with intravenous thrombolysis with some effect.The mri showed evidence of an embolic phenomenon, probably from the polymer material.Nine weeks later, she was re-admitted after suffering a general tonic-clonic seizure.Mri showed diffuse t2 hyperintensity of the left cerebral hemisphere.Lamotrigine which was later switched to levetiracetam was started as anti-epileptic prophylactic.Oral prednisolone 100 mg once daily was started.Model and catalog number are not available, but the suspected device is the prolwer mc.Other cnv devices that were also used in this study: none.Non-cnv devices that were also used in this study: 4f vertebralis.Catheter (cook), 6f sheath (iva, balt), 017 sl-10 microcatheter (stryker), 5 mm x 10 mm copernic balloon (balt), 6f fargomax guiding catheter (balt), 017 headway duo microcatheter (microvention), and 4 mm x10 mm transform.Supercompliant balloon (stryker).Publication details: title: delayed leukoencephalopathy from suspected.Polymer embolism after neuroendovascular procedures.Objective: as the neurointervention field grows, a new side effect emerges.Delayed leukoencephalopathy (dl) is believed to be an inflammatory or allergic reaction to polymer material that is shed from catheters during endovascular procedures.Methods: we present four cases of dl after aneurysm treatment in two patients, endovascular stroke treatment and diagnostic arteriography.We present our diagnostic process, including biopsy results in two patients, our anti-inflammatory treatment and outcomes together with a review of the literature.
