Basilar aneurysm is a vascular disease of the skull and it is a type of intracranial aneurysm. Basilar aneurysms usually occur at the tip of the basilar artery, which is the end of the basilar artery, near where the basilar artery divides into the posterior cerebral arteries on either side. Intracranial aneurysm is a benign lesion, which is a kind of cystic protrusion on the wall of intracranial artery caused by various congenital developmental abnormalities, or acquired factors. The wall of this cystic protrusion is very thin, and it can easily rupture and bleed when emotionally excited and blood pressure is elevated, thus leading to subarachnoid hemorrhage, and the patient will suffer from severe headache, nausea, vomiting, coma, and even life-threatening. Therefore, once a basilar aneurysm is detected, surgery should be performed in a timely manner, which is usually minimally invasive interventional aneurysm embolization because the location of the basilar aneurysm is deep and cranial clamping is more traumatic. Minimally invasive interventional embolization is performed by puncturing the right femoral artery, inserting a miniature catheter into the vicinity of the aneurysm, and then filling a spring coil into the aneurysm through the miniature catheter to tightly embolize the aneurysm to eliminate it and prevent it from rupture and bleeding.
