What is Arnold Chiari Malformation?
Arnold - Chiari Malformation is a pathological circumstance in which some tissue of learning ability tend to stretch into the spinal canal . This usually happen if the skull is extremely small and out of shape pressurise the wit to move in a downward direction . Arnold - Chiari Malformation is quite rare but with forward motion of aesculapian science and the technology available these years this disease is diagnosed more frequently and easily . There are two types of Arnold - Chiari Malformations , type I and eccentric II . Arnold - Chiari Malformation Type I develop when the child is growing and the kid may not experience any symptom until late puerility or early adolescence . Arnold - Chiari Malformation Type II which is the more unwashed sort of Arnold - Chiari Malformation is congenital and is present at the time of the parentage of the child . handle Arnold - Chiari Malformation depends on the austereness of the malformation and the type of deformity with observation , medications and OR being the favourite pick of intervention .
What Causes Arnold Chiari Malformation?
Causes of Arnold - Chiari Malformation Type I : This physical body of malformation come when the section of the brain which contains the cerebellum is distorted or deformed thus pressurizing the brain . In this malformation the lower part of the cerebellum relocation into the spinal canal .
Arnold - Chiari Malformation Type II : This is most commonly caused due to a medical experimental condition called as myelomeningocele .
Now the dubiousness is what happens when the cerebellum is push into the top part of the spinal canal . When this happens , it tend to interfere with the flow of the CSF or cerebrospinal fluid which protects the brain and the spinal cord . This impaired flow of CSF causes signaling transmitted from the Einstein to other parts of the body to get hinder or accumulation of CSF into the brainiac or the spinal cord resulting in symptoms .
What are the Risk Factors for Arnold Chiari Malformation?
Some studies target to a genetic link to development of Arnold - Chiari Malformation even though this is still a matter of ongoing enquiry and investigations .
What are the Symptoms of Arnold Chiari Malformation?
As submit , Arnold - Chiari Malformation is classify into two main types and the symptoms due to them are name below .
Symptoms of Arnold - Chiari Malformation Type I : In this character the child may not feel any symptoms until late childhood or early adolescence and this miscreation is usually an incidental determination on see bailiwick conduct to reign out some other disorderliness . Some of the symptoms go through by the patient of Arnold - Chiari Malformation Type 1 are :
Symptoms of Arnold - Chiari Malformation Type II : As state , this case of malformation usually occurs with a aesculapian consideration called as myelomeningocele . Some of the symptoms that the child with Arnold - Chiari Malformation Type II may experience are :
How is Arnold Chiari Malformation Diagnosed?
To commence with the plow physician will take a detailed story of the affected role as to when the symptoms started and how severe the symptom are . A forcible examination will also be conducted to look for sealed reproducible neurologic symptoms . If Arnold - Chiari Malformation is suspected then imaging subject field will be ordered to include MRI scan of the brain and spinal cord which will give three dimensional images of the brain and spinal cord and clearly show a misshapen skull and the cerebellum going into the spinal epithelial duct . Once Arnold - Chiari Malformation is confirmed , repeated MRIs may be carry so as to check the position of the consideration .
How is Arnold Chiari Malformation Treated?
The handling options for treating Arnold - Chiari Malformation are dependent on the type of the malformation and the severity of it . In case if the misshapenness make no symptoms at all then the doctor may just quetch reflection of the term with in series magnetic resonance imaging look for any changes in the malformation and no specific treatment is interpret . Pain medications may be collapse for symptom of frequent headaches and other pains which may be experience by the affected role . For more severe conformation of Arnold - Chiari Malformation operating theatre is the best-loved route to go . The procedure that is done is to relieve the force per unit area that is put on the brain and the spinal corduroy due to the deformity and thus stop progress of the disease and still the symptom . Once the procedure is completed successfully then the pressure on the brain and spinal electric cord is significantly reduced and there is rest period from the lot of the symptoms . The most common surgical operation performed for Arnold - Chiari Malformation is be intimate as posterior fossa decompression where the sawbones will remove a small portion of the bone behind the skull to make more way for the mentality to flourish an thus relieving the pressure from the mastermind . The surgeon may also take away a part of the spinal column to relieve force per unit area being put on the spinal cord . As is the case with all surgical routine , there are integral risks in this surgery as well to include risks of contagion , accumulation of fluid in the brain , CSF leakage , and check lesion healing . Almost all of the symptom of Arnold - Chiari Malformation are relieved after successful pass completion of the surgery but in case of there is a spunk injury in the spinal corduroy then surgery may not be able to reverse the damage already done . Postprocedure , the patient will require regular checkups in the form of serial MRI and other imaging run to look at the condition of the brain and spinal cord and hold the position of Arnold - Chiari Malformation .
