Patient: Male, 40 years old, usually a non-smoker, occasionally drinks a little wine when socializing, blood pressure is not high. At 6:20 a.m. on the 20th, he went to the bathroom for a short while, fainted and passed out, had convulsions and bitten his tongue, his stool was not dry, and he did not feel uncomfortable. After more than half an hour, he became conscious, had a headache and vomited, and cried out for leg pain. The CT showed a hemorrhage in the subretinal cavity and he was admitted to the neurosurgery ward, where 320 CT was taken at noon and the film was taken in the afternoon. He was admitted to the neurosurgery ward at noon for a 320 CT scan. On the 23rd, he was transferred to the general ward, and now he has no problems with speaking, arms and legs, but still has headache. Can you give any treatment advice? Doctor: Left anterior artery A3 segmental spindle aneurysm with high possibility of entrapment aneurysm. Interventional treatment should be preferred. However, since this artery is thinner than the opposite anterior artery, and the distal end of A1 is tortuous downward and then reflexed upward, it is estimated that it is quite difficult to place a stent; microsurgical treatment includes wrapping or isolation. In order to prevent distal ischemia of the anterior artery after isolation, end-to-end vascular anastomosis can be performed, but there is a possibility of complications such as difficulty in anastomosis, failure, and post-anastomotic vasospastic stenosis leading to hemiplegia and convulsions. Similar complications are possible with interventional therapy. The above is for reference only, or you can see my clinic.
