脑桥Duret出血是继发性的，由向下压迫导致穿孔小动脉的牵拉缺血形成。各种类型损害--出血、水肿以及任一类型的肿块病变均可引起压迫性病变。
The so-called Duret hemorrhages seen here in the pons are secondary to downward compression that leads to stretching and ischemia of perforating arterioles. The compression can result from a variety of lesions--hemorrhages, edema, mass lesions of any type.
