1.What is embolization of cerebral aneurysm?
Through cerebral angiography, the site and type of aneurysm are clarified, and embolization material is delivered into the cavity of the aneurysm by microcatheter technology, and the aneurysm is occluded by using spring ring or other embolization material to thrombose the aneurysm by itself to achieve the treatment purpose.
2.Which patients need to do aneurysm embolization?
①Patients with advanced age and poor general condition.
②Patients with severe SAH (H-H:IV-V) who have improved symptoms after external drainage of cerebrospinal fluid.
③Posterior circulation aneurysm, periocular artery, saccular aneurysm with direct surgical access difficulties (internal carotid artery sea surface sinus segment, etc.).
④Patients with cerebral vasospasm stage can be treated with simultaneous interventional vasospasm treatment.
⑤ No severe atherosclerosis, vascular distortion, or vasospasm is not severe after rupture and bleeding.
3.The advantages and disadvantages of aneurysm embolization?
Advantages.
①Puncture is performed in the femoral artery at the root of the thigh with an incision of about 2mm.
②Minimally invasive to the whole body, high safety, sure efficacy, short operation time.
③No damage to the normal penetrating vessels around the vessel, which can reduce the complications of the procedure.
④The purpose of hemostasis can be achieved by interventional embolization in case of aneurysm rupture.
Disadvantages
①If the intracranial hematoma is large, the hematoma cannot be removed.
②If the vascular tortuosity is severe, it is impossible to place the microcatheter in the aneurysm.
③The risk of embolization of the distal end of the aneurysm-carrying artery.
④The risk of aneurysm rupture during surgery.
4.What is the effect of aneurysm embolization?
The therapeutic effect of aneurysm embolization is close to the effect of aneurysm clamping surgery, which can achieve cure of aneurysm or acute phase I treatment to prevent rebleeding. For patients who have developed cerebral vasospasm, intravascular anti-spasticity drug infusion or vasodilation can be performed at the same time. Because aneurysm embolization has the advantages of less surgical trauma and lower complications, many countries now make aneurysm embolization the treatment of choice.
