A patient who had undergone cerebrospinal fluid shunt for hydrocephalus 10 years ago suddenly developed strong vomiting and drowsiness when she was more than 7 months pregnant. Her family thought it was a pregnancy reaction at first, but gradually the pregnant woman developed hypertension, squinting eyes and other symptoms, and after she was admitted to a local hospital, the patient’s father worried whether his daughter’s condition was a recurrence of hydrocephalus and remembered his classmate Li Xiaoyong. Professor Li Xiaoyong is the founder of the academic theory of cerebrospinal fluid neurosurgery in China and the world, and is currently the director of the Cerebrospinal Fluid Disease Center of the Department of Neurosurgery at the Aviation General Hospital. Professor Li was very anxious after listening to the situation of the pregnant woman and suggested that an MRI be performed immediately to determine her condition. However, the local hospital mistakenly believed that MRI has X-rays like CT, which may deform the fetus, and refused the family’s request for the examination. After a week of treatment according to the eclampsia aura, the patient’s condition worsened and she developed intermittent drowsiness and uncontrollable blood pressure. At the repeated request of the patient’s family, the pregnant woman underwent an MRI, and sure enough, hydrocephalus recurred, suggesting blockage of the cerebrospinal fluid drainage duct. The local hospital advised the pregnant woman to stop the pregnancy immediately to avoid endangering the adult’s life. However, the pregnant woman, who was more than 7 months old, insisted on keeping her baby, and when no local hospital was willing to accept her, the patient’s father called Li Xiaoyong again. Knowing that the life of the pregnant woman and the fetus could be in danger at any time, Director Li suggested that they bring the patient to the hospital immediately. When the family arrived at the Aviation General Hospital at 5:00 p.m. on December 27, 2011, the pregnant woman was basically unable to walk, her reaction was slow, her face was red and she had a strong reaction to vomiting. Director Li immediately decided to give the patient an emergency cerebrospinal fluid shunt extraction and temporary hydrocephalus control technique under local anesthesia at 7:00 pm. Before surgery, Director Li said to the family, “Although we have not encountered this situation, we rely on our new technology and try our best to keep your mother and child safe!” Hearing these words, the patient’s family’s heart, which was in their throat, was much calmer. Sure enough, the day after the operation, the pregnant woman no longer vomited, the mental state returned to normal, high cranial pressure caused by hypertension also got more satisfactory control, but also ate three duck pears in one breath. Although the patient’s symptoms were relieved, Director Li still faced two difficulties: first, to ensure the safe and smooth delivery of the pregnant woman; second, to ensure that the patient’s hydrocephalus was completely cured. There was no literature available for such a special case, so we had to rely on the new technology of cerebrospinal fluid neurosurgery created by Prof. Li Xiaoyong in close cooperation with obstetrics. Upon learning about this matter, Gao Guolan, the director of the Aviation General Hospital, immediately arranged for Director Cai Zhengyu of the Department of Obstetrics to consult with Director Li to discuss and develop a complete treatment and care plan that would ensure both the safety of the fetus and the control of the mother’s hydrocephalus during pregnancy. On January 14, 2012, the obstetrician found that the fetus might be in intrauterine distress, and that this little life might die in the mother’s womb. The obstetrician performed an emergency cesarean section on the mother. As the sun set, the lucky baby boy let out his first loud and clear cry, and the pregnant woman was moved to tears as she held the hard-won baby. After the patient’s delivery, Li Xiaoyong continued his scientific treatment by utilizing the new technology he had studied for nearly 8 years for the treatment of hydrocephalus and its complications. Finally, 47 days after admission, the patient’s cerebrospinal fluid met the criteria for performing a cerebrospinal fluid shunt. Director Li performed a ventriculo-abdominal shunt under general anesthesia on February 13, 2012. The operation was a complete success and the patient’s life was saved. From being on the verge of death to enjoying the joy and happiness of a family of three, the patient’s husband could not help but deeply sigh: “When we first came here, Director Li told us that if we had come a week later, both lives would not have been saved. Fortunately, we found Director Li in time, otherwise I don’t know how many wrongful paths we would have to take, and I probably wouldn’t be able to see these two mothers now.” For more than a decade, Professor Li Xiaoyong has been summing up a whole set of cerebrospinal fluid treatment techniques, and has reached a new level of treatment for all kinds of hydrocephalus. The traditional view is that women with hydrocephalus shunts who develop shunt infection or blockage during pregnancy must choose to terminate their pregnancy. Director Li uses vivid examples to prove to us that women can have children without worries even after hydrocephalus shunts, and that the new technology of cerebrospinal fluid neurosurgery has brought happiness to thousands of female patients and their families by removing their worries.
