The little tail on your butt is not to be taken lightly, it’s a neurological condition called Spinal Embolism Syndrome (SES). So what is spinal embolism syndrome? The pathogenesis of the disease can be easily understood from the literal hints, that is, the spinal cord nerves are embolized, just as the steed on the grassland is tied by the rope, losing its freedom, and can not gallop on the grassland. Then the spinal cord also loses its freedom, losing the space for free growth and development. From a medical point of view, spinal cord embolism is caused by congenital or acquired factors that result in abnormal tissue pulling on the spinal cord, limiting its movement and causing an abnormal increase in tension in the spinal cord, which leads to a series of clinical symptoms and signs, mainly including dysfunction of urination and defecation, motor and sensory disorders of both lower limbs, physical deformities and pain. It can lead to serious sequelae and high disability rate. What causes “spinal cord embolism syndrome”? Spinal Cord Embolism Syndrome (SCES) is caused by abnormal development of the neural tube, which often occurs during the 18th to 28th day of pregnancy, as this period of gestation is the prime time for neurodevelopment. Numerous studies have shown that the lack of folic acid in pregnant women during this period is an important cause of neural tube malformations in newborns. It is important for expectant mothers to take appropriate folic acid supplements during the pre-pregnancy period. Of course, certain genetic and acquired factors may also contribute to spinal embolism syndrome. What are the physical manifestations of spinal embolism syndrome? The most obvious signs in babies are small tails above the buttocks, small depressions containing hair, localized lumps in the midline region of the lower back, etc. The most important clinical signs are the power of the baby’s urine, the short or dribbling urine line, the inability to pass stools, the dryness of the stools, and, in more serious cases, the deformity of the feet, the unattractive gait, or even more serious deformities. The treatment for a small tail on the buttocks is surgery. Only surgery can separate the abnormal tissue connected to the spinal cord and allow the spinal cord to regain its freedom so that it can grow and develop freely within the spinal canal. The surgeon needs to carefully separate the spinal cord nerves from the pulled abnormal tissues under a microscope to loosen the adhesion of the surrounding tissues, relieve the clinical symptoms, and prevent further deterioration of the neurological function. Since the surgery requires prone positioning to prevent nerve adhesions, babies need to be trained to sleep in the prone position for a period of time before preparing for the surgery, which is conducive to recovery after the surgery.
