What is a spinal cord embolism with spinal membrane expansion?

       Myelomeningoeele (MMC) is a congenital neurodevelopmental malformation due to congenital vertebral plate hypoplasia, with the presence of spinal cord and spinal membrane bulging out of the spinal canal through the vertebral plate defect. China is a high incidence area, the incidence rate of about 0.1% a 1.0%, serious damage to the physical health of our children and their families bring a huge economic and emotional burden. Currently, it is believed that spinal cord bulge is caused by a combination of factors. These include environmental factors and genetic theory. The pathology and morphology, as well as the combination of deformed tissues, can be divided into three categories.  Spinal bulge A cystic mass that occurs in the midline of the back. It varies in size and width at the base, and the surface skin is mostly normal.  Spinal cord bulge The spinal bursa bulges out from the broken vertebral plate and varies in size, with a more extensive base. The bursa is lined with dura mater, and the neck of the bursa is usually wide. The contents of the bursa are of two types: one with a few nerve roots protruding into the bursa and attached to the bursa wall. In the other case, there is a spinal cord bulge in the lumbosacral region with the spinal cord and its nerve roots protruding into and attaching to the bursa. The spinal cord and nerve tissue protruding into the capsule may be only loosely attached to the capsule wall, but in some cases, they may be tightly attached to the capsule wall or even indistinguishable from it. Therefore, the degree of nerve damage varies greatly. In some cases, the skin on the surface of the mass is thin and scar-like, and in some cases, there are squamous epithelial carcinoma changes. Spinal bulge and spinal cord spinal bulge are sometimes combined with lipoma, called lipoma-type spinal bulge or lipoma-type spinal cord spinal bulge.  Spinal cord outgrowth or spinal cord bulge is rare. The spinal canal and dura are widely open and the spinal cord and nerve tissue are directly exposed. There may be neurodegeneration.  Spinal cord bulge can cause neurological symptoms such as low back pain, numbness and weakness in the lower extremities, urinary and bowel disorders, and habitual abortion. The quality of life of the patient can be seriously affected. In principle, these diseases are suitable for surgical treatment.  The main points of the surgery are: 1. Remove the spinal membrane bulging capsule and repair the soft tissue defect, simple spinal membrane bulging can be cured by this surgery; 2. Explore the spinal cord and nerves bulging into the spinal membrane capsule. Give free, decomposition, so that it is returned to the spinal canal. Not blindly removed; 3, spinal cord spinal membrane bulge surgery, usually need to expand the vertebral plate incision upward and downward in order to explore and deal with the spinal canal, and conducive to the bulging nerve tissue returned; 4, combined with hydrocephalus and symptoms of increased intracranial pressure, the first hydrocephalus shunt to relieve intracranial pressure, the second step for spinal membrane bulge resection repair; 5, reaching into the thoracic cavity, abdominal fragmentation, the pelvic cavity of the spinal membrane bulging mass, often requiring laminectomy and thoracic, abdominal, pelvic joint surgery.  The timing of surgery advocates early surgery, the spinal cord of infants and young children with spinal membrane bulge, but also take into account their circumstance and endurance of surgery. Infants and children who have complete paralysis of the lower limbs, incontinence, used to be considered a contraindication to surgery, but the current development of anesthesia and microsurgery techniques, selective surgery, may also achieve good results.
