Contrast Induced Encephalopaty after Percutaneous Peripheral Intervention

Abstract

Contrast-induced encephalopathy (CIE) is a rare complication of angiography. Presently reported is the case of a patient diagnosed with CIE following peripheral angioplasty with the non-ionic contrast agent, iohexol. A 66-year-old male patient described intermittent claudication and peripheral arterial disease was suspected. Lower extremity angiography was performed, and following dilation of a 7.0x150-mm balloon, a 9.0x57-mm stent was placed in the lesioned vessel. The patient subsequently developed confusion and cortical blindness, and a seizure occurred 1 hour after the procedure. An emergency cerebral computed tomography scan did not reveal any signs of intracerebral hemorrhage. The neurological symptoms disappeared within 24 hours after hydration and sedative medication. CIE was diagnosed based on the patient`s clinical course findings and cerebral imaging.

Contrast-induced encephalopathy and permanent neurological deficit following cerebral angiography: A case report and review of the literature

“…However, four of them were excluded because it was defined as allergic reactions, vasospasm, and posterior reversible encephalopathy syndrome, and complete data were not available in the other six papers. Finally, we accurately summarized 30 papers ( Leong and Fanning, 2012 ; Yan and Ramanathan, 2013 ; Kocabay et al, 2014 ; Nagamine et al, 2014 ; Hamra et al, 2017 ; Park et al, 2017 ; Spina et al, 2017 ; Dattani et al, 2018 ; Heemelaar et al, 2018 ; Hirata et al, 2018 ; Kahyaoğlu et al, 2018 ; Tong et al, 2018 ; Renault and Rouchet, 2019 ; Riahi et al, 2019 ; Şimşek et al, 2019 ; Zhao et al, 2019 , 2021 ; Fernando et al, 2020 ; Harada et al, 2020 ; Lei et al, 2020 ; Liu et al, 2020 ; Andone et al, 2021 ; Cristaldi et al, 2021 ; García-Pérez et al, 2021 ; Kamimura et al, 2021 ; Li et al, 2021 ; Vigano et al, 2021 ; Yao et al, 2021 ; Zhang et al, 2021 ; Rashid et al, 2022 ). A total of 127 patients were enrolled.…”

Contrast-induced encephalopathy following intra- arterial iodinated contrast media injection in patients with atherosclerotic cardiovascular disease: A retrospective analysis

“…Generally, CIE following intervention procedures is rare and sparsely documented in the literature. All previous studies [2][3][4][5][6][7][8][9][10][11][12][13] have mainly focused on the sporadic case reports. Therefore, the current study focuses on the patients with CIE following atherosclerotic cardiovascular disease (ASCVD).…”

Clinical Discussion on Contrast-induced Encephalopathy with Clinical Manifestation of Cerebral Hemorrhage

“…The application value of contrast agent in disease diagnosis has been affirmed, and the foundation also has been laid for early intervention of relevant diseases. With the extensive application of contrast agent in clinic, the literatures on adverse effects of contrast agent also increase gradually [1,2]. Based on the reports of numerous scholars, the adverse effects of contrast agent include mild adverse effects such as dizziness, nausea and emesis, and moderate adverse effects such as chest distress, chest pain and dyspnea.…”
