That day, the beautiful girl was surrounded by a group of family members and came into my consultation room. From the intermittent narrative of the nervous family, I learned the reason: the girl has a twin sister, the two sisters have a very good relationship, from birth to today has gone through 22 years, the two have never been separated, play together and read together, sleep together and get up together. This morning, the sister suddenly had a headache and fell to the ground and passed out, her family sent her to our emergency room, and the result of the head CT was “cerebral hemorrhage”, and is now being resuscitated in the ICU. The family said that the doctor could not tell the exact cause of the brain hemorrhage. Since the two sisters were identical, their parents were afraid that it was due to a genetic disease and that the sister might also develop the disease, so they brought her here and asked to have her examined. When I opened up the CT images of my sister’s head, I was astonished: the ruptured cerebral blood vessel was in the head of the left caudate nucleus, blood broke into the ventricles, and there was blood accumulation in the left lateral ventricle, the third ventricle, and the fourth ventricle! This condition is often caused by the rupture of intracranial aneurysm, which is due to the congenital poor development of the elastic layer of intracranial blood vessels, and under the long-term impact of blood flow, the weak point of blood vessels slowly bulge and finally form “aneurysm”. If the blood breaks into the ventricles and subarachnoid space, the cerebrospinal fluid circulation channels will be blocked and the intracranial pressure will be even higher, which will soon lead to brain tissue displacement and eventually brain herniation, compressing the vital center and affecting breathing and heartbeat. At this point, you can only turn to the gods! ”Sister’s condition is very bad oh, is it necessary for the machine to help breathing?” ”The doctor said that my sister is in a coma and is using a machine to breathe.” It’s hopeless! I thought to myself. ”That could be a ruptured aneurysm. The condition is really serious. My sister should also be tested for a cranial CTA to rule out a hemangioma, but it’s more expensive.” ”How expensive it is to check! Originally, it was fun to watch them twins grow up together! Now that this has happened, I don’t even know how to face it.” The mother choked up and said. Today, the results came back. The sister’s right internal carotid artery was considered a hemangioma with a localized aneurysm-like bulge. I explained the results to her family. ”How is my sister doing now?” ”Gone that night!” The blooming flower withered at the most brilliant time. The light of life is like a candle in the wind, the wind passes by and the candle is extinguished; it is also like the sound of string music, the string breaks and the sound stops. Life is so short and fleeting! The dead are already long, and the living are always sorrowful. “relatives or remaining sorrow, others have also sung”, the best means of heaven to treat human suffering is time, time to let people forget everything, including the separation of life and death. The mother will always forget her sister’s untimely departure, after all, there is still a sister; but, the sister must have great courage to live! How can she face the sudden departure of her sister, who has been with her for 22 years and has become one with her? Moreover, there is a safety risk in her body, an aneurysm that could rupture at any time! No one can predict when the lonely sister in heaven will remember her sister who is still in the world and beckon to her. The world is full of people who are afraid of cancer. The most frequently asked question by patients or family members is “Is it cancer?” Even if it is as mild as a cold, there are still such questions! The most common cause of death is vascular diseases, including cardiovascular and cerebrovascular diseases. Life is so unpredictable, so why not cherish every day?
