Cerebrovascular disease seriously affects people’s quality of life, in practice, we often encounter examples of people suffering from serious cerebrovascular disease, but do not get the attention of patients and their families, but when they know the seriousness, it is often the time when they cannot take treatment or lose the opportunity of treatment, so I want to publicize the necessity of cerebrovascular disease treatment through my blog, and strengthen people’s awareness of the disease is an imminent necessity. It is an important historical moment for people to be aware, to receive treatment, to avoid cerebrovascular accidents, to improve people’s quality of life and to prolong their life span through publicity ……… Aneurysm —- is a local protrusion of the cranial artery wall, forming a sac-like bulge, internal blood flow changes and local artery wall thinning, resulting in late rupture, causing subarachnoid hemorrhage, serious life-threatening, treatment of aneurysm is urgent, aneurysm treatment includes two kinds: 1, surgical treatment. The latter is a new type of treatment, using the femoral artery puncture, introducing catheters and other materials through the puncture site, and filling the aneurysm with spring coils and other materials to occlude the artery as a minimally invasive treatment. This aneurysm will not only rupture and cause bleeding, but also have an occupying effect (i.e., squeezing the surrounding brain or nerve tissue) and cause neurological dysfunction, such as actinic nerve palsy, and also cause the thrombus inside the aneurysm to dislodge and embolize the cerebral vessels, causing cerebral infarction, etc. The figure below shows a middle cerebral artery aneurysm admitted to our hospital, in which the aneurysm ruptured and caused arachnoid hemorrhage. The patient was diagnosed with aneurysmal subarachnoid hemorrhage by cranial magnetic resonance imaging (MRI), and was given an emergency intra-aneurysmal spring coil embolization. The aneurysm of middle cerebral artery (MCA) was found on MRI, which was more regular and round. Further DSA examination was performed to confirm the aneurysm, which was located at the bifurcation of MCA, and spring coil embolization was decided. After spring coil embolization, the original aneurysm disappeared, and the aneurysm-carrying artery was unobstructed, which did not affect the blood supply to brain tissue.
