Arteriovenous Malformations (AVM)

Understanding Arteriovenous Malformations

Arteriovenous malformation (AVM) is a complex vascular condition that requires specialized medical expertise. Our comprehensive approach combines advanced diagnostics with personalized treatment plans to ensure optimal patient outcomes.

About Arteriovenous Malformations?

An arteriovenous malformation is an abnormal connection between arteries and veins that bypasses the normal capillary system. These malformed blood vessels can occur anywhere in the body, including the brain, spinal cord, face, colon, and other organs. AVMs are typically congenital, meaning they develop before birth, though symptoms may not appear until later in life.

The abnormal vessel formation creates a direct pathway between high-pressure arteries and low-pressure veins, potentially leading to serious complications if left untreated.

What Causes Arteriovenous Malformation?

Most arteriovenous malformations are congenital abnormalities that develop during fetal growth. The exact cause remains unclear, but researchers believe AVMs result from errors in vascular development during embryonic stages.

 

Key factors include:

  • Genetic mutations: Rare hereditary conditions may increase AVM risk
  • Developmental anomalies: Disruption in normal blood vessel formation
  • Sporadic occurrence: Most AVMs occur randomly without family history
  • Environmental factors: Limited evidence suggests potential prenatal influences
Symptoms

What are the Symptoms of Arteriovenous Malformation?

Arteriovenous malformation symptoms vary significantly depending on location, size, and blood flow patterns. Many patients remain asymptomatic for years, while others experience severe complications.

Common AVM Symptoms Include:

Peripheral AVMs

Gastrointestinal AVMs

Neurological AVMs:

1

Neurological AVMs:

  • Severe headaches or migraines
  • Seizures or epileptic episodes
  • Neurological deficits or weakness
  • Vision or speech disturbances
  • Cognitive changes or confusion

2

Peripheral AVMs:

  • Visible pulsating masses
  • Localized pain or discomfort
  • Skin discoloration or warmth
  • Ulceration or bleeding
  • Limb swelling or enlargement

3

Gastrointestinal AVMs:

  • Recurrent bleeding or anemia
  • Abdominal pain or cramping
  • Changes in bowel movements
  • Unexplained blood loss
Complications

What are the Complications of Arteriovenous Malformation?

Untreated arteriovenous malformations can lead to life-threatening complications requiring immediate medical intervention. Understanding these risks emphasizes the importance of early detection and treatment.

Serious AVM Complications:

Hemorrhage:

Heart Failure:

Neurological Damage:

Local Tissue Damage:

1

Hemorrhage:

  • Rupture causing internal bleeding
  • Stroke risk in cerebral AVMs
  • Potentially fatal blood loss

2

Heart Failure:

  • Increased cardiac workload
  • High-output heart failure
  • Cardiovascular complications

3

Neurological Damage:

  • Permanent brain injury
  • Cognitive impairment
  • Motor function loss

4

Local Tissue Damage:

  • Chronic pain and disability
  • Functional impairment
  • Progressive tissue destruction

FAQ

Frequently Ask Question

Advanced diagnostics and minimally invasive treatment for arteriovenous malformation with our expert multidisciplinary team and state-of-the-art technology.

The ICD-10 codes for arteriovenous malformation vary by location. Common codes include Q28.2 for arteriovenous malformation of cerebral vessels and Q27.3 for peripheral vascular malformations. Your healthcare provider will use the appropriate code based on your specific diagnosis.

An arteriovenous malformation is an abnormal tangle of blood vessels where arteries connect directly to veins without normal capillaries in between. This creates abnormal blood flow patterns that can cause various symptoms and complications.

While arteriovenous malformation pictures can provide educational information, proper diagnosis requires advanced imaging studies performed by qualified medical professionals. Clinical examination and specialized radiology are essential for accurate assessment.

Arteriovenous malformation of the colon can cause significant bleeding and anemia. While potentially serious, most cases respond well to appropriate treatment including endoscopic therapy or surgical intervention when necessary.

Yes, facial arteriovenous malformations can be effectively treated using various minimally invasive techniques including embolization and sclerotherapy. Treatment requires specialized expertise to preserve facial function and appearance.
