题型:配伍题 B1型题

题目:

由于器质性病变致肠腔变小,使肠内容物通过发生障碍者,称为()。
肠腔不通同时伴肠壁血运障碍者,称为()。

A.动力性肠梗阻

B.血运性肠梗阻

C.机械性肠梗阻

D.不完全性肠梗阻

E.绞窄性肠梗阻

答案:

参考答案:C,B

解析:肠梗阻根据其发生的原因可分为三类:①机械性肠梗阻,由于各种原因引起肠腔狭小,肠内容物通过发生障碍所致;②动力性肠梗阻,是由于神经反射或毒素刺激引起肠壁肌功能紊乱,肠蠕动丧失或肠管痉挛,肠内容物不能正常运行,并无器质性的肠腔狭窄;③血运性肠梗阻,系由于肠系膜血管栓塞或血栓形成,肠管血运障碍而发生肠麻痹、肠梗阻。按梗阻的程度可分为完全性和不完全性肠梗阻。按肠壁有无血运障碍分类:①单纯性肠梗阻,仅表现为肠内容物通过受阻,而无肠管血运障碍;②绞窄性肠梗阻,既有肠内容物通过受阻,又伴有肠壁血运障碍者。
