Basilar Artery Occlusion Due to Repeat Transradial Coronary Angiography: A Case Report of Latrogenic Cerebral Embolism.

The aim was to report a rare case of basilar artery occlusion due to repeated transradial artery puncture. The patient was a 62-year-old woman who underwent repeated transradial arterial puncture for coronary artery examination and treatment of coronary artery disease. During the second transradial coronary angiography, the patient suddenly developed typical symptoms of basilar artery occlusion, such as confusion, coma, and limb movement disorders. Subsequently, the patient underwent urgent ADAPT thrombus aspiration and a series of symptomatic supportive treatments. Within 6 h after the procedure, the patient's symptoms improved significantly, and at the time of discharge, the patient's overall recovery was satisfactory despite mild neurologic deficits. This case emphasizes the need to pay great clinical attention to the potential risks of transradial artery puncture operation and its possible far-reaching impact on the patient's prognosis, and provides an important reference for clinicians in terms of operation standardization and complication prevention.
