高场强磁共振能分辨脑出血5期12个阶段不同的信号特点,还能分辨脑梗塞新近期与陈旧期.经临床与磁共振(MR)诊断的高血压性脑出血73例中发现血肿与梗塞并存者40例(54.8%),其中15例(41.6%)在脑出血前即早已存在,故称之为“双重性”中风并分为3个亚型:(1)A 型指新近血肿与新近梗塞并存7例(17.5%);(2)B 型指新近血肿与陈旧梗塞并存26例(65%);(3)C 型指陈旧血肿与陈旧梗塞并存7例(17.5%).在40例并存的脑梗塞中有36例为腔隙性梗塞.40例高血压“双重性”中风的血肿36例为大灶性(90%),4例为小灶性(10%),后者临床表现为出血性腔隙综合征.40例“双重性”中风的出血灶与梗塞灶均在穿支动脉系统,说明高血压性脑出血与腔隙性脑梗塞是同一疾病的两种发病形式.
High-field MRI can distinguish different characteristics of 12 stages of cerebral hemorrhage in stage 5, and can distinguish between new and old cerebral infarction.Hematogenous hemorrhage was found in 73 cases diagnosed by clinical and magnetic resonance (MR) 40 cases (54.8%) were complicated by infarction, of which 15 (41.6%) had already existed before cerebral hemorrhage, so it was called “duality” stroke and divided into three subtypes: (1) (2) B type refers to the coexistence of new hematoma and old infarction in 26 cases (65%); (3) C type refers to the coexistence of old hematoma and old infarction in 7 cases (17.5%). Thirty-six of 40 patients with cerebral infarction were lacunar infarcts. Thirty-six (40%) cases of hypertensive “dual” stroke had focal lesions (90%) and 4 were focal (10%), Clinical manifestations of hemorrhagic lacunar syndrome .40 cases of “dual” stroke in both hemorrhage and infarction are perforating the branch artery system, indicating that hypertensive intracerebral hemorrhage and lacunar infarction are the two forms of the same disease .
