Medical history: 3 months before admission, the patient underwent DSA examination in our hospital. Because of the "left posterior communicating artery aneurysm", the aneurysm was clipped and recovered well. 6 + months later, the CTA of the head showed that the intracranial aneurysm had been clipped. After communicating with the family members, the patient underwent interventional embolization.<br>Physical examination: clear mind, no positive sign, pathological sign (-), neck obstruction (-), GCS 15 points.<br>Imaging examination: CTA: right internal carotid artery extracranial aneurysm, intracranial aneurysm after clipping.<br>DSA: the aneurysm of the extracranial segment of the right internal carotid artery was 8 * 4mm in size and irregular in shape.<br>Preoperative diagnosis: right internal carotid artery extracranial aneurysm, left posterior communicating artery aneurysm after clipping.<br>Aspirin 100 mg and clopidogrel 75 mg were given orally 3 days before operation.<br>Treatment: under general anesthesia, stent implantation was performed on the parent artery of the extracranial segment of the right internal carotid artery.<br>The patients were given antispasmodic, symptomatic and supportive treatment.<br>Aspirin 100mg QD and clopidogrel 75mg QD were taken until 6m after operation.<br>Case 3: basic information: patient, male, 66 years old.<br>Chief complaint: recurrent paroxysmal amaurosis in left eye for 1 week.<br>History: one week before admission, the patient developed amaurosis in the left eye, which was paroxysmal, with a total of 3-4 times, and each attack lasted for 3-4 seconds.
