摘要
报告２４例大块脑梗塞的脑局解病例，对其中１６例ＨＩ的病理特点及发生机制进行探讨。结果证实：ＨＩ占本组大块脑梗塞的发生率为７１．４％，脑血栓ＨＩ的发生率为６０％。ＨＩ多发生在梗塞灶的边缘区及皮质区，以小静脉和毛细血管出血为主。ＨＩ的发生与梗塞的体积及动脉血压增高有关。其发生机制可能是周边区或皮质区侧枝循环建立和脑水肿导致静脉回流障碍，血液淤滞所致。本文还证实溶栓治疗与其它治疗比较并未见出血扩大。
The paper reported 24 cases of topographic autopsy with massive cerebral infarction, among them 16 cases with haemorrhage infarction(HI). The pathologic characteristics and mechanism of HI were observed. The results showed that HI amounted to 66. 7 % in cerebral embolism, and HI amounted to 60. 0 % (6/10) in cerebral thrombosis. Most HI were found at the border of the infarction focus and the cortical area, and mainly attributed to haemorrhage from small veins and capillaries. The occurrence of HI may related to infarction size and to increased arterial pressure. The mechanism of HI may be related to the formation of collateral circulation at the border or cortical area, and to the ence-phaledema resulting in disturbance of venous return and hypostasis. The results also indicated that HI was not aggravated through thrombolytic therapy.
