Some people say that a small fish spike can be fatal? Of course it can. When a person accidentally swallows a fish spike, it is most likely to get stuck in the pharynx and esophagus, the pharynx is easier to deal with, once the spike is in the esophageal wall, the problem becomes complicated. This is where I will focus: aortoesophageal fistulas caused by fish spikes, aortic pseudoaneurysms. When a fish spike punctures the esophagus and punctures the aorta, it can lead to massive vomiting of blood, which can be fatal. Even if the aorta is not punctured, a peripheral infection may form in the punctured esophagus, and infection involving the aorta can lead to an aortic pseudoaneurysm that eventually ruptures and causes hemorrhage. If a timely visit is made, it is usually done by implanting an intra-aortic stent to stop the life-threatening bleeding and control the infection, followed by opportunistic second-stage surgery for aortic replacement or repair and esophageal repair. This is a very risky and difficult disease to treat. Therefore, prevention is the first priority, and be careful about eating spiny and thorny fish. If a fish spike inadvertently gets stuck in the pharynx or esophagus, first of all, do not get nervous, and do not swallow vegetables or buns, etc., which may make the spike lodge deeper. If it is only stuck in the throat, it can be seen from the mouth and can be removed by pressing down the tongue and using forceps. Of course, it is best to go to the hospital. If it is stuck in the esophagus, do not wait to see it, but go to the hospital right away to avoid any future problems. Not only fish spikes, swallowed bones, larger vegetable stems, etc. can lead to adverse consequences.
