RESUMEN
Objective To explore the effect of type 2 diabetes mellitus(T2DM) on vascular damage characteristics of acute cerebral infarction and the impact on the short term prognosis.Methods One hundred and fifty-six cases of acute cerebral infarction patients were selected and divided into the T2DM group with 64 cases and non-T2DM group with 92 examples.According to the whole cerebral angiogram,the results and the results of the treatment of acute cerebral infarction and prognosis were analyzed.Results The incidence of intracranial artery stenosis of the T2DM group was 79.69％ (51/64),of non-T2DM group was 58.70％ (54/92),the difference between two groups was significant(x2=12.856,P＜0.05).The incidence of before andafter intracranial artery stenosis coexist,circulation narrow coexist in T2DM group was 50.00％ (32/64),59.36％(38/64) respectively,in non-T2DM group was 21.74％(20/92),29.35％(27/92) respectively,the difference between groups was significant(x2 =9.652,8.659;P＜0.05).The incidence of multivessel lesions and diffuse lesions and without collateral compensatory in T2DM group was 71.88％ (46/64),65.63％ (42/64) and 71.88％(46/64) respsctively,in non-T2DM group was 54.35％(59/92),39.13％(36/92) and 31.52％(29/92) respectively,thedifference between groups was significant(x2=8.625,9.354,11.053;P＜0.05).The total effective rate after 2 weeks of treatment in T2DM group was 46.88％(30/64),in non-T2DM group was 90.22％(83/92),the difference between groups was significant(x2=8.061,P＜0.05).Conclusion The incidence of intracranial artery stenosis in patients with intracranial artery stenosis combined with T2DM is higher than the control group,and lesion range widely,diffuse damage,vascular damage moderately severe stenosis and occlusion are significantly higher than in non-T2DM group,especially without collateral compensatory rates is higher than non-T2DM group,while the neural function damage of T2DM group is heavier and poorer prognosis.
RESUMEN
Objective To study the clinical features and angiographic findings of moyamoya disease (MMD) as well as their relationship. Methods A total of 22 MMD patients received routine digital substraction angiography (DSA). The clinical manifestations and angiographic findings were analyzed. Results Clinical manifestations varied and each patient often had multiple symptoms, including cerebral infarction in 9 patients with an average age of 23.6 (13-39 years) and cerebral hemorrhage in 7 patients with an average age of 31.2 (28-46 years). Angiographic examination found that all the diseased sides showed MMD blood vessels. The patients who received encephalo-myo-arterio-synangiosis (EMAS) had better prognosis than those without receiving the treatment. Conclusion Cerebral infarction is frequent in children and adolescents with MMD, whereas cerebral hemorrhage is common in adults. DSA is a golden criterion for diagnosing MMD. Surgical treatment, EMAS blood supply reconstruction in particular, should be prescribed.
