Mr. Zhou from Anhui recently experienced a life-and-death test. Not long ago, Mr. Zhou, who was ready to get up, suddenly felt a severe headache, followed by frequent vomiting, and was urgently called 120 and sent to the emergency department of the Third Hospital. The emergency cranial CT indicated massive subarachnoid hemorrhage, followed by rapid deterioration of his condition, loss of consciousness, cessation of spontaneous breathing, general bruising and drop in blood pressure, which made his life critical. In the face of the critical situation, the emergency department immediately performed cardiopulmonary resuscitation and called the anesthesia department for tracheal intubation and ventilator-assisted breathing, and his vital signs gradually stabilized and his consciousness improved. It was necessary to perform angiography (DSA) as soon as possible to clearly diagnose and occlude the aneurysm at the same time, otherwise it would deteriorate again and cause death once it bleeds again. The emergency plan was started immediately, and a “whole brain angiogram” was performed for Mr. Zhou under general anesthesia with the support of DSA and anesthesia department. Director Jinping Liu introduced that the rupture and bleeding of cerebral artery entrapment aneurysm is an extremely dangerous disease with high mortality rate, especially the vertebral artery entrapment aneurysm (VADA) suffered by Mr. Zhou, which is clinically rare, adjacent to the brainstem medulla respiratory and heartbeat center, and easily combined with hydrocephalus or brainstem failure after rupture and bleeding. The survival rate does not exceed 5%. The only option is interventional embolization. The neurosurgery department rose to the challenge and decided to use the latest “LVIS stent-assisted spring coil technique” to successfully embolize the aneurysm after discussion. Director Jinping Liu said that since the vertebral artery entrapment is mostly a paralleling tear of the vessel wall in the direction of blood flow, this treatment not only avoids the direct impact of the paralleling blood flow on the weak aneurysm wall, but also reduces the continued impact and tearing of the entrapment inflow tract on the aneurysm-carrying artery, minimizing the risk of recurrence or rebleeding of the entrapment after surgery, and the possibility of long-term healing of the entrapment. After the operation, through tracheotomy and drainage of bleeding from the lumbar pool, the patient recovered consciousness, and the tracheal cannula was successfully removed, and his condition gradually stabilized. Currently, Mr. Zhou is under further rehabilitation. The successful treatment of this patient was the result of our neurosurgery department opening a “green channel” according to the standard procedure for treatment of cerebral aneurysm and performing cerebral angiography to clarify the diagnosis, which is also closely related to the rapid progress of cerebrovascular interventional technology. The high metal coverage of the stent has provided a relatively reliable method for difficult to treat aneurysms, including clotted aneurysms, and further reduced the recurrence rate of aneurysms.
