Type II and III spinal vascular malformations
Introduction
Introduction to type II and III spinal vascular malformations Type II (spheroidal vascular malformation) and type III (immature or extensive vascular malformation) occurring in spinal cord vascular malformations in the spinal canal, the lesion being located in the spinal cord. Its incidence accounts for 10% to 15% of all spinal vascular malformations. The treatment of intramedullary vascular malformations often requires intravascular therapy and microsurgery. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: autonomic dysfunction, sexual dysfunction
Cause
Causes of type II and III spinal vascular malformations
Cause:
It is a developmental abnormality or deformity of congenital spinal cord blood vessels. The affected spinal cord is more common in the thoracic segment, followed by the lumbosacral segment. There are also those who are involved in the full length of the spinal cord. Sudden head and neck or lumbosacral pain, incomplete or complete paraplegia or quadriplegia can occur clinically. Paraplegia has a remission period is its characteristic performance. The age of onset is more common in young and middle-aged people. Many patients get better results if they can get early diagnosis and radical surgery.
Prevention
Type II and III spinal vascular malformation prevention
Pay attention to rest, work and rest, life in an orderly manner, and maintaining an optimistic, positive and upward attitude towards life can be of great help in preventing diseases.
Complication
Complications of type II and III spinal vascular malformations Complications, autonomic dysfunction, dysfunction
Can be complicated by acute neurological dysfunction, sensation, exercise, sphincter and sexual dysfunction.
Symptom
Symptoms of type II and III spinal vascular malformations common symptoms, sensory disturbance, weakness, spinal cord disease, vascular malformation
The clinical manifestations of patients with intramedullary type are significantly different from those of dura mater. The former often causes intramedullary and subarachnoid hemorrhage. About 3/4 of patients have a history of hemorrhage, and one third of patients have acute neurological function. Symptoms of the disorder, manifested as progressive limb muscle weakness, sensory disturbances, sphincter dysfunction and sexual dysfunction, about 1 in 5 patients with intramedullary vascular malformations with intramedullary aneurysms, which are often located in the intramedullary Most of the main nourishing blood vessels, patients with spinal aneurysms can have subarachnoid hemorrhage, and the history is mostly long. Patients with lesions in the middle thoracic segment have a worse prognosis than patients with other lesions. This may be related to the side of the segment. The number of vascular vessels is small and the sagittal diameter of the spinal canal is small, while the prognosis of the cervical segment is better.
Examine
Examination of type II and III spinal vascular malformations
MRI examination plays an important role. Intramedullary lesions can be distinguished by the stomata sign on the T1-weighted image. In the T2-weighted image, abnormal signals often appear in the spinal cord. The stenosis around the spinal cord indicates the part around the spinal cord lesion. Spinal artery angiography plays an important role in determining the extent and nature of intramedullary lesions. In particular, DSA techniques may be useful in distinguishing between type II and type III lesions. The procedure should be selective and bilateral brachial artery or Bilateral femoral artery injection angiography, as part of the screening test, selective aortic cannulation and intubation angiography of the vertebral artery, carotid artery and iliac crest have a corresponding role in determining the nourishing artery supplied by the intramedullary lesion. Choose as appropriate.
Diagnosis
Diagnosis and diagnosis of type II and III spinal vascular malformations
In addition to the general clinical symptoms, MRI examination plays an important role in the diagnosis of intramedullary vascular malformation. The intramedullary lesions can be distinguished by the airflow sign on the T1-weighted image, and abnormal signals often appear in the spinal cord on the T2-weighted image. The levitation around the spinal cord suggests a part of the spinal cord lesion. Spinal artery angiography plays an important role in determining the extent and nature of the intramedullary lesion. Especially the DSA technique will help to distinguish between type II and type III lesions. There should be a choice, if necessary, bilateral iliac artery or bilateral femoral artery injection angiography, as part of the screening test, selective aortic cannulation and vertebral artery, carotid artery and iliac crest catheterization in the determination of the marrow The nourishment arteries supplied by the internal lesions have corresponding effects and can be selected as appropriate.
