The patient is a middle-aged woman, 52 years old, who was diagnosed with acute subarachnoid hemorrhage due to sudden severe headache with inability to open her left eye and diplopia, and was treated conservatively for 10 days in a local hospital. The patient’s family found out online that Donglei Brain Physicians Group is a team of experts in treating cerebral hemangioma, and took the risk of traveling to the clinical base of Donglei Brain Physicians Group to seek medical treatment. In order to let the patient get timely and effective treatment, the experts of the group, Professor Song Donglei and Director Gai Yanting, immediately arranged the emergency clinic for the patient to carry out the whole cerebral angiography, and the results of the angiography found that the posterior traffic aneurysm was ruptured, and there was the danger of rupture and bleeding at any time, and the patient’s life might be in danger of being lost once bleeding again! In order to save the patient’s life, after discussing with the patient’s family, and despite the hard work of two surgeries already performed, he urgently formulated a surgical plan and performed a craniotomy to clip the aneurysm for the patient overnight, and the surgery was a complete success. On the first postoperative day, the left ophthalmoplegia improved compared with the preoperative period, and the diplopia improved without any complication. The patient was discharged from the hospital 8 days after the operation, with the cleft of the left eye basically restored to normal, slight diplopia, and without any sequelae. There are two methods of treatment for ruptured aneurysms, one is craniotomy and the other is interventional embolization. Craniotomy is the classic aneurysm treatment plan, especially for wide carotid aneurysm, bifurcation aneurysm, etc., craniotomy has good effect and low recurrence rate, and some scholars have put forward the principle of “clipping priority”, but craniotomy is traumatizing, with high risk and many complications. Interventional embolization has been increasingly accepted by doctors and patients due to less trauma, faster recovery and fewer complications. Moreover, with the advancement of interventional materials and therapeutic techniques (e.g., flow steering devices such as pipeline), some intracranial aneurysms that were previously thought to be untreatable by interventional embolization have also achieved satisfactory results through interventional embolization. Dr. Gai Yanting of Donglei Brain Physicians Group has rich experience in minimally invasive interventional treatment and microsurgical treatment of intracranial aneurysms, and was the first to develop pipeline embolization devices for the treatment of cerebral aneurysms in China, with a level of technology that is at the international advanced level. At present, the international clinical aneurysm treatment guidelines also point out that for intracranial aneurysms that can be treated with both craniotomy and interventional embolization, it is recommended to adopt the interventional embolization treatment method. Therefore, the treatment method of intracranial aneurysm should be studied and formulated by neurosurgeons and neurointerventionalists, and individualized treatment methods should be adopted according to the specific conditions. The wishes of the patient and family should also be taken into consideration.
