Objective To explore the relationship between the size and location of the aneurysm after subarachnoid hemorrhage (aSAH) and its clinical classification. Methods A retrospective study was performed in patients with aSAH from January 1, 2008 to December 31, 2014. The relevant clinical data were collected including age, gender, aneurysm size, location, and Hunt-Hess (H-H) classification. The aneurysms were classified by size (A group d<5.00 mm, B group 5.00 mm≤d<10.00 mm, C group d≥10.00 mm), location and H-H classification according to the results of CT, digital subtrac?tion angiography (DSA), and magnetic resonance angiography (MRA). The relationship between size, position of aneurysm and H-H classification was observed and analyzed. Results There were 750 cases included in this study, with average age (56.14 ± 11.88), male 292 and female 458. The total number of aneurysms was 903, and the number of multiple aneurysms was 91 (12.13%). There was one case with multiple aneurysms that can be included in A, B and C groups. There were two cases with multiple aneurysms that can be included in A and B groups, two cases can be included in A and C groups, and three cases can be included in B and C groups. The number of aneurysms and the ratios of groups A, B and C were 20(3.9%), 12 (3.8%), 5 (7.5%), 70 (13.6%), 39 (12.2%), 10(14.9%), 2 (0.4%), 4 (1.3%), 2 (3.0%), 165 (32.0%), 94 (29.4%), 6 (9.0%), 130 (25.2%), 90 (28.1%), 6 (9.0%), 17 (3.3%), 11 (3.4%) and 2 (3.0%) for the location in the anterior cerebral artery, the middle cerebral artery, the posterior cerebral artery, the internal carotid artery, the anterior communicating artery, the posterior communicating artery, and the vertebral basilar artery, respectively. The number of aneurysms and the ratios of H-H classificationⅠ,Ⅱ,Ⅲ,ⅣandⅤin groups A, B and C were 48 (9.3%), 45 (14.1%), 12 (17.9%), 228 (44.2%), 150 (46.9%), 14 (20.9%), 68 (13.2%), 54 (16.9%), 30 (44.8%), 142 (27.5%), 43 (13.4%), 9 (13.4%), 30 (5.8%), 28 (8.8%) and 2 (3.0%). There was a negative correlation between the size of aneurysm and the H-H grade (rs=-0.075, P=0.024). Conclusion The anterior communicating artery and posterior communicating artery are high-risk areas for smaller aneurysms. The internal ca?rotid artery is high-risk areas for larger aneurysms. The size of aneurysm is negatively correlated with H-H classification.

ObjectiveTo analyze and compare the difference and prognosis between vascular embolization and craniotomy occlusion in patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) with Hunt-Hess levelⅢ-Ⅳ, and acute postoperative hydrocephalus.Methods A retrospective study was conducted on 767 patients who had undergone vascular embolization (vascular embolization group,n = 403) or craniotomy occlusion operation (craniotomy occlusion operation group,n = 364), and the patients with postoperative acute hydrocephalus were screened. The clinical data of patients of both groups was analyzed. By judging short-term prognosis in patients with hydrocephalus with Glasgow outcome scale (GOS) score estimated at discharge, the advantages and disadvantages of two surgical procedures were compared.Results The number of cases with postoperative hydrocephalus in vascular embolization group was 56 (13.90%), while that in craniotomy occlusion group was 33 (9.07%). The difference between the two groups of incidence of hydrocephalus was statistically significant (χ2= 4.350,P = 0.037 ). In 767 patients with aSAH, the incidence of hydrocephalus among the patients after the hematoma removal operation was significantly lower than that of patients without hematoma removal [3.07% (11/358) vs. 19.07% (78/409),χ2 = 47.635,P = 0.000]. The incidence of hydrocephalus among the patients after ventricular drainage was significantly lower than that of patients without the drainage [2.77% (19/685) vs. 85.37% (70/82),χ2 = 487.032,P = 0.000]. In 403 cases of vascular embolization group, the incidence of hydrocephalus in the patients after the hematoma removal operation was lower than that of patients without it [8.06% (5/62) vs. 14.96% (51/341),χ2 = 2.082,P = 0.168]. The incidence of hydrocephalus in the patients after the ventricular drainage was lower than that of patients without drainage [2.59% (9/347) vs. 83.93% (47/56),χ2 = 266.599,P = 0.000]. In 364 cases of craniotomy occlusion operation group, the incidence of hydrocephalus in the patients after hematoma removal operation was significantly lower than that of patients did not receive [2.03% (6/296) vs. 39.71% (27/68),χ2 = 95.226,P = 0.000]. The incidence of hydrocephalus among the patients after the ventricular drainage was significantly lower than that of patients without drainage [2.96% (10/338) vs. 88.46% (23/26),χ2 = 203.852,P = 0.000]. The difference in incidence of hydrocephalus between the patients who had hematoma removal surgery between vascular embolization group and craniotomy occlusion operation group was statistically significant [8.06% (5/62) vs. 2.03% (6/296),χ2 = 4.411,P = 0.027], while no statistically difference was present in ventricular drainage patients [2.59% (9/347) vs. 2.96% (10/338),χ2 = 0.085,P = 0.819]. There were 23 patients (41.07%) with good outcome (GOS score 4-5), while 33 (58.93%) with poor outcome (GOS score 1-3) in 56 patients undergone vascular embolization operation. Good result (GOS score 4-5) was shown in 21 (63.64%) and 12 (36.36%) with poor outcome (GOS score 1-3) among 33 patients with hydrocephalus after craniotomy occlusion operation, and the difference was statistically significant (χ2 = 4.230,P = 0.039).Conclusions Hematoma is one of the main factor contributing to the differences in the incidence of postoperative hydrocephalus of Hunt-Hess gradeⅢ-Ⅳ patients either receiving vascular embolization or craniotomy occlusion operation. Lateral ventricle drainage may not be the factor that contributes to the difference in incidence of hydrocephalus formation between the vascular embolization and craniotomy occlusion operation groups in Hunt-Hess levelⅢ-Ⅳ patients. The short term prognosis in the craniotomy occlusion operation group is superior to that of endovascular intervention embolization group.
