By the 6th month, the subendothelial layer could be distinguished. 内皮下层第6个月可辨认出来。
When the pressure reached 600 mmHg, one third of the EC loss and subendothelial layer denuding was seen right after the hydraulic dilation. 压力为600mmHg时,扩张后即刻检测,近1/3的内皮细胞有脱落与内皮下层裸露;
Conclusions ( 1) Detachment of EC is more severe with the increase in hydraulic dilation pressure. Moreover, the subendothelial layer tends to be exposed. 结论(1)内皮细胞的脱落随着液压扩张压力的增加而进一步加重,内皮下层裸露也广泛。
