问题 单项选择题

关于甲亢手术治疗,下列哪项叙述是正确的

A.通常需切除双侧腺体的60%~70%

B.处理甲状腺上血管时应远离甲状腺上极

C.结扎甲状腺下动脉要尽量离开腺体背面靠近颈总动脉处

D.甲状腺峡部应予保留

E.止血充分时,术野可不放置引流

答案

参考答案:C

解析:甲状腺大部切除通常切除腺体的80%~90%+峡部。术中:①应保持甲状腺背面完整,以免损伤紧贴背面的甲状旁腺;②结扎甲状腺上动脉,应紧贴甲状腺上极,以免损伤喉上神经;③结扎甲状腺下动脉,应远离甲状腺下极,以免损伤喉返神经。保留甲状腺峡部,术后易导致甲亢复发。为防止术后血肿压迫气管导致窒息,术中应常规放置引流,术后床边应备气管切开包。

I have a friend named Monty Roberts who owns a horse ranch (大牧场) in San Isidro. He lets me use his house to hold events to raise money for youth at risk programs.

The last time I was there he greeted me by saying, “I want to tell you why I let you use my house. It all goes back to a story about a young man who was the son of a poor horse trainer who would go from stable (马厩) to stable, farm to farm, training horses. As a result, the boy’s high school was continually interrupted (打断). One day in the last year of high school, he was asked to write a paper about what he wanted to do when he grew up.

“He wrote a seven-page paper about his goal of owning a horse ranch in great detail. He put a great deal of his heart into the project and even drew a detailed floor plan for the dream ranch. Then the next day he handed it in to his teacher. Two days later he received his paper back. But he got a low mark with a note that read, ‘See me after class.’

“The boy went to see the teacher after class and asked, ‘Why did I receive a low mark?’

“The teacher said, ‘This is an unrealistic dream for a young boy like you. You have no money. You come from a poor family. Owning a horse ranch requires a lot of money. There’s no way you could ever do it, your dream couldn’t come true . ’Then the teacher added, ‘If you will rewrite this paper, I will reconsider your mark.’

“The boy went home and thought about it long and hard. He asked his father what he should do. His father said, ‘Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.’

“Finally, the boy turned in the same paper, making no changes at all. He wrote, ‘You can keep the low mark and I’ll keep my dream.’

“I was that boy twenty years ago.” My friend said, smiling.
