【动静脉瘘】
An arteriovenous (AV) fistula is an abnormal connection between an artery and a vein. Normally, blood flows from your arteries to your capillaries to your veins. Nutrients and oxygen in your blood travel from your capillaries to tissues in your body.
With an arteriovenous fistula, blood flows directly from an artery into a vein, bypassing some capillaries. When this happens, tissues below the bypassed capillaries receive a diminished blood supply.
Arteriovenous fistulas usually occur in the legs, but can develop anywhere in the body. Arteriovenous fistulas are often surgically created for use in dialysis in people with severe kidney disease.
A large untreated arteriovenous fistula can lead to serious complications. Your doctor monitors your arteriovenous fistula if you have one for dialysis.

《一号难求》
提前半个月0点放号，0点过5分，号已经抢光了。患者纷纷发微信，说系统是不是坏了，怎么一个号都没有了？夜猫子的我告诉患者哪周门诊取消，哪周出。已经坐上火车的就联系别的出诊教授现场给加个号。今天有个患者坐了一上午火车空着腹，下午不好意思插队，一直在等，刚好我记住了她名字，赶忙把她的病历本儿先放前面，看完了好去抽血，第二天复诊也不用再挂号了。也没想到患者从内蒙古拎着特产来，扔下就走，只觉得这都是应该做的。因为望着对面的老师，一整天看了81个患者，上午问诊，下午出结果更改治疗方案，一个患者看两遍，每个都详细问诊，也没喝口水，娟秀的字迹细致工整的写得病历本满满当当，还要体察患者情绪，还得帮着学生（我）和患者沟通，在患者由于长时间等待就诊差点儿和我火儿起来的时候化解患者的急躁……最近看王海鸰写的医疗小说，感觉其实身处其中，动起笔来，大概每个医学生都可以写出无休止符的故事，琐事即故事。

【蜘蛛痣】spider naevi
1⃣️A spider angioma 血管瘤or spider naevus (plural（复数） spider naevi) is a type of telangiectasis毛细管扩张(swollen blood vessels) found slightly beneath the skin surface, often containing a central red spot and reddish extensions which radiate outwards like a spider's web. They are common and may be benign, presenting in around 10–15% of healthy adults and young children. However, having more than three spider angiomas is likely to be abnormal and may be a sign of liver disease. It also suggests the probability of esophageal varices.食管静脉曲张
2⃣️Spider angiomas form due to failure of the sphincteric muscle surrounding a cutaneous皮肤 arteriole小动脉. The central red dot is the dilated arteriole and the red "spider legs" are small capillaries carrying away the freely flowing blood. If momentary pressure is applied, it is possible to see the emptied capillaries refilling from the center. No other angiomas show this phenomenon.
3⃣️The dilation扩张, in turn, is caused by increased estrogen levels in the blood. Many pregnant women and women using hormonal contraception激素类避孕药 have spider angiomas, which is due to high estrogen levels in their blood. Individuals with significant liver disease also show many spider angiomas, as their liver cannot metabolize circulating estrogens, specifically estrone雌酮, which derives from the androgen androstenedione雄烯二酮.About 33% of patients with cirrhosis have spider angiomas.
