Treatment of Spinal Arteriovenous Malformation in Turkey

Treatment of Spinal Arteriovenous Malformation (AVM) in Turkey

A comprehensive guide about spinal arteriovenous malformation (AVM). Important information about causes and symptoms of the malformation, diagnostic and treatment methods, in addition to the advantages of treatment in Turkey.

Introduction:

What is Spinal Arteriovenous Malformation (Spinal AVM)?
Spinal arteriovenous malformation (AVM) is a rare disorder affecting the blood vessels in the spinal cord, where there is an abnormal connection between arteries and veins. This causes disruption in blood flow and reduced oxygen supply to the nervous tissues. This abnormal tangle may appear on the surface of the spinal cord, inside it, or near it. If left untreated, it may lead to permanent spinal cord damage.

Spinal AVMs are complex cases that may go undiagnosed until symptoms such as limb weakness or back pain appear. If diagnosed early, spinal AVM can be treated using advanced surgical or radiation techniques, as is common in Turkey, which is considered a leading destination thanks to its advanced medical infrastructure and the expertise of its neurosurgeons.

Symptoms of Spinal Arteriovenous Malformation (Spinal AVM)

Symptoms vary from person to person depending on the location, size of the malformation, and degree of nerve involvement. In many cases, early symptoms may not appear, and the patient may remain undiagnosed for years. However, severe and sudden symptoms can emerge that threaten neurological function and quality of life.

Main signs and symptoms associated with spinal AVM include:

• Difficulty walking or climbing stairs due to muscle weakness or loss of balance.

• Numbness, tingling, or prickling sensations in the feet or legs, often sudden.

• Muscle weakness on one side or both sides of the body.

• Sharp, sudden back pain possibly accompanied by neurological symptoms.

• Loss of sensation in the lower limbs or reduced sensitivity to heat or pain.

• Difficulty urinating or defecating due to nerve involvement.

• Headache and neck stiffness, especially in cases with bleeding or pressure on the spinal cord.

Symptoms typically begin in young adulthood, especially in the twenties, but can also appear in childhood or later. Early diagnosis and attention to unusual neurological changes are crucial to prevent permanent complications caused by spinal AVM.

What Causes Spinal Arteriovenous Malformation (AVM)

The exact causes of spinal AVM are not fully known. Most cases are classified as congenital malformations, meaning they develop during embryonic growth and are present at birth. Less commonly, these vascular malformations may appear later in life due to still-under-study reasons.

No clear genetic or risk factors directly lead to spinal AVM, and it affects males and females almost equally.

Despite its rarity, untreated AVM can cause serious complications due to disrupted normal blood flow in the spinal cord, including:

• Weakness or difficulty moving due to nerve damage.

• Pain, tingling, or numbness in the lower limbs.

• Damage or atrophy of spinal tissues due to oxygen deficiency.

• Formation of aneurysms (blood vessel dilation).

• Venous hypertension causing spinal cord edema (fluid buildup).

• Spinal cord infarction, leading to nerve tissue death from lack of blood supply.

• Sudden spinal hemorrhage, which can rapidly worsen symptoms or cause permanent neurological loss.

Early diagnosis and appropriate treatment decisions can help avoid these complications and improve the patient’s long-term quality of life.

How to Accurately Diagnose Spinal AVM

Diagnosing spinal AVM can be complicated because its symptoms resemble other spinal conditions such as spinal dural arteriovenous fistula, spinal stenosis, multiple sclerosis, or spinal tumors. Accurate diagnosis requires specialized medical evaluation using advanced imaging techniques.

Main diagnostic methods for spinal AVM include:

• Magnetic Resonance Imaging (MRI):
  A fundamental test to detect abnormal blood vessels in the spinal cord. MRI uses radio waves and strong magnetic fields to produce detailed images showing tangled blood vessels inside or around the spinal cord. It helps localize the vascular mass caused by AVM.

• Angiography:
  The most accurate test to pinpoint the exact location and features of the malformation. A thin catheter is inserted via an artery in the thigh (femoral artery) and guided to spinal blood vessels. A special contrast dye is injected to visualize blood flow under X-ray.
  This test is crucial for planning surgery or other treatments.

Due to the sensitivity of the condition, these tests are recommended to be performed at specialized centers for spine or vascular diseases, ideally under the supervision of a neurologist or vascular surgeon experienced with spinal AVM.

Best Treatment Methods for Spinal AVM in Turkey

Turkey offers effective treatment for spinal AVM using the latest medical and surgical technologies. Treatment choice depends on factors such as the size and location of the malformation, blood flow amount, neurological exam results, and overall patient health.

Treatment Goals:

• Reduce the risk of bleeding.

• Prevent neurological deterioration.

• Relieve pain and improve quality of life.

Treatment options in Turkey include:

1. Medication (Pain Relievers and Neurological Support):
   Used to ease symptoms like back pain and neurological stiffness but does not cure the malformation. Usually part of a comprehensive treatment plan.

2. Conventional Surgery to Remove Spinal AVM:
   Surgical removal via incision to excise the AVM entirely, especially if small and accessible without harming the spinal cord. Requires a neurosurgeon specialized in AVM due to proximity to sensitive nerves.

3. Endovascular Embolization:
   One of the most common procedures in Turkey to reduce blood flow to the AVM by:

   • Inserting a thin catheter through a femoral artery.

   • Guiding it to the artery feeding the AVM.

   • Injecting a special adhesive (medical glue) to block the abnormal vessels.
     This procedure is often done before surgery to minimize bleeding or shrink the malformation.

4. Stereotactic Radiosurgery:
   Uses highly focused radiation beams to target abnormal vessels, gradually closing them. Ideal for small, unruptured spinal AVMs. It is a non-surgical procedure without incisions.

Advantages of Treating Spinal AVM in Turkey

• Advanced specialized medical centers for microsurgery of the nervous system.

• Neurosurgeons with global experience in treating spinal AVM.

• Competitive prices compared to European countries.

• Fast diagnosis and treatment processes.
