[Abstract]:Research background
Intracranial aneurysms are the abnormal bulge of intracranial arterial wall, and the first cause of subarachnoid hemorrhage (SAH). They are the third cause of cerebrovascular diseases. The mortality and disability rate of SAH patients are about 22% - 25% of the total death rate of cerebrovascular diseases. The mortality of first rupture of intracranial aneurysms and hemorrhage is increasing gradually. The mortality rate is about 15%-20%. The mortality rate is 75%-85% in 2 years without prompt treatment. More than 50% of the survivors of ruptured aneurysms have left varying degrees of dysfunction.
In recent years, with the continuous development of interventional materials and endovascular treatment technology, endovascular treatment has gradually become the preferred treatment of intracranial aneurysms. With its advantages of minimally invasive, endovascular treatment has also been rapidly accepted by clinicians and patients with intracranial aneurysms. With the development of imaging equipment, microcatheters, microwire and coils However, as a minimally invasive technique, intravascular interventional therapy for intracranial aneurysms is still unavoidable. The overall incidence of complications can reach 8% - 10%. Some patients even suffer from permanent disability or even permanent disability. Cause death.
It is reported that the recanalization rate of aneurysms is still high after endovascular treatment. The results also show that the recanalization of aneurysms is closely related to the degree of embolization, and the higher the degree of embolization, the less the chance of recurrence. At present, embolization results after endovascular treatment of aneurysms are often used, that is, after endovascular treatment of aneurysms, angiography, according to whether the aneurysm is developed and the degree of development to judge. Usually used: 1. Written description: complete embolization, "dog ear" like residue, neck residue, body residue. 2 Embolization percentage expression: 1. 00%, 99% ~ 90%, 90% or 100%, 99% ~ 95%, 95%; 3) Combine the two methods. When using these semi-quantitative methods to evaluate the embolization effect, different judges may come to different conclusions, so they can not be used as an objective evaluation index for endovascular treatment of aneurysms. As a quantitative index for evaluating the embolization effect of aneurysms, tumor volume ratio has gradually become a research hotspot.
Objective: Immediate embolization of intracranial aneurysms is closely related to the recanalization of aneurysms. Compact embolization can significantly reduce postoperative recurrence. The purpose of this study is to study the value of dual-volume imaging in evaluating the effect of immediate embolization of intracranial aneurysms, and to analyze the related factors affecting the results of immediate embolization of intracranial aneurysms, so as to provide clinical treatment. For theoretical basis and guidance.
METHODS: The data of 43 patients with intracranial cystic aneurysms treated by endovascular interventional therapy in the Department of Neurosurgery, Wuhan General Hospital of Guangzhou Military Region from January 2013 to June 2013 were collected. Each aneurysm was studied as an independent individual with 43 aneurysms. The size, location, neck size, aneurysm volume, treatment method, coil volume, embolization degree of aneurysm (dense embolism and non-dense embolism) were analyzed. The two imaging techniques, two-dimensional DSA (two-dimensional DSA) and two-volume imaging (two-dimensional DSA) were compared to show the residual aneurysm ability. Complete embolization: Neither aneurysm nor neck had contrast agent filling imaging; Neck residue: Neck of aneurysm had contrast agent filling imaging but no contrast agent filling imaging; Neck of aneurysm residue: Neck of aneurysm had contrast agent filling imaging; Neck of aneurysm residue: Neck of aneurysm had contrast agent filling imaging, which was considered aneurysm embolization failure. All statistical data were analyzed by SPSS13.0 statistical analysis system. The difference was statistically significant when P 0.05.
Results: A total of 43 patients, including 25 females and 18 males, had an average age of 56.36 with ruptured aneurysms, 7 with unruptured aneurysms, 25 with stent-assisted coil embolization, 18 with simple coil embolization, 9 with dual-microcatheter embolization, 19 with posterior communicating aneurysms, 10 with anterior communicating aneurysms, and 7 with middle cerebral artery. There were 7 aneurysms, 3 ophthalmic aneurysms, 3 superior clinoid aneurysms, 1 anterior cerebral artery A1 aneurysm, 19 aneurysms less than 5 mm: 20, 5 mm to 10 mm: 19, more than 10 mm: 4. The aneurysms ranged in size from 7.3 mm3 to 2498 mm3, with an average of 190.15 mm3, the aneurysms less than 50 mm3 to 100 mm3: 13, 50 mm3 to 100 mm3: 10, and more than 100 mm320 aneurysms. From 1.58 mm to 9.16 mm, average 4.29 mm, neck-body ratio from 1.01 to 2.56, average 1.39. According to neck-body ratio, they were divided into three groups: less than 1.5 mm: 32 cases, 1.5 mm to 2 mm: 8 cases, more than 2 mm: 3 cases, aneurysm tamponade rate from 4% to 38%, average 18.25%, less than 10% - 15%: 9 cases, 15% - 20%: 16 cases, more than 20%: 14 cases. There were 16 cases (37.2%) with complete embolization, 16 cases (37.2%) with residual tumor neck and 11 cases (25.6%) with residual tumor neck. There were significant differences between the two groups (Z = - 2.009, P = 0.045). The packing rate of complete embolization group was 0.20 [0.07], and non-embolization group was evaluated by 2D-DSA. The filling rate of complete embolization group was 0.16 [0.04]. Although the filling rate of complete embolization group was higher than that of residual aneurysm group, there was no significant difference between the two groups (t = 1.918, P = 0.0620.05). The filling rate of complete embolization group was 0.22 [0.06], and that of incomplete embolization group was 0.16 [0.05] by dual volume imaging. The filling rate of complete embolization group was significantly higher than that of incomplete embolization group (t = 3.037 P 0.05). Multivariate Spearman analysis showed that the size of aneurysm (r-0.353 P = 0.020) and the volume of aneurysm (r-0.449 P = 0.003) were the influencing factors of intracranial aneurysm compact embolization.
Conclusion: Dual-volume imaging can improve the detection rate of aneurysm embolization residual immediately. Dual-volume evaluation of dense embolization of intracranial aneurysms has a high rate of tamponade. Low.
