Abnormal Artery-to-Vein Connection
Blood can pass directly from arteries to veins through abnormal vessels without the usual capillary network.
Vascular Malformation Care
Arteriovenous Malformation (AVM) Treatment in Hyderabad
Arteriovenous malformations are abnormal connections between arteries and veins. Evaluation and treatment depend on the AVM's location, size, blood-flow pattern, symptoms and individual vascular anatomy.
Individualised Evaluation
Detailed imaging and specialist assessment help determine whether
observation, embolization, surgery, or another treatment approach
is appropriate.
Understanding Arteriovenous Malformations
An arteriovenous malformation (AVM) is an abnormal network or direct connection between arteries and veins that bypasses the normal capillary circulation. AVMs can occur in different parts of the body and may have different clinical features depending on their location.
Some AVMs may cause no symptoms and are discovered during evaluation for another reason, while others can be associated with pain, swelling, bleeding, skin changes, a visible or pulsating lesion, or other location-specific symptoms.
Why specialist evaluation matters
AVM treatment is not one-size-fits-all. Imaging helps define the feeding arteries, draining veins and overall vascular anatomy before a treatment plan is selected.
About AVMs
What Can an AVM Involve?
The presentation varies according to where the malformation is located and how blood flows through it.
Different Body Locations
AVMs may occur in different tissues and organs, so symptoms and treatment options vary according to the anatomical site.
Variable Blood Flow
Some malformations have high-flow characteristics. Understanding the flow pattern is important when planning treatment.
Symptoms
Possible Signs of an Arteriovenous Malformation
Symptoms depend strongly on the AVM's location, size and vascular flow.
- Pain or discomfort in the affected area
- Swelling or a visible abnormality
- Skin colour or temperature changes
- A pulsating or throbbing sensation in some high-flow lesions
- Unexplained bleeding from an affected area
- A palpable or visible vascular mass
- Progressive symptoms or enlargement of the lesion
- Other symptoms related to the specific anatomical location
Seek urgent medical attention for sudden or severe symptoms.
Significant bleeding, sudden neurological symptoms, severe pain, loss of consciousness or rapidly worsening symptoms require immediate medical assessment.
Diagnosis
How Are AVMs Diagnosed?
Clinical examination is combined with imaging to understand the anatomy and blood-flow pattern of the malformation.
Clinical Examination
A specialist evaluates symptoms, the location of the lesion, skin findings, swelling, pulsation and other relevant signs.
Doppler Ultrasound
Doppler imaging may help assess blood flow and vascular connections in suitable superficial or accessible lesions.
CT or MRI
Cross-sectional imaging may be used to define the extent and relationship of a vascular malformation to surrounding structures.
Angiography
In selected cases, angiography can provide detailed information about feeding arteries, the nidus and draining veins.
Flow Assessment
Understanding whether the lesion behaves as a high-flow or lower-flow vascular malformation can influence treatment planning.
Multidisciplinary Review
Depending on the anatomical site, complex AVMs may require coordination between vascular, interventional, surgical or other relevant specialists.
Treatment
AVM Treatment Options
Treatment is selected after reviewing symptoms, imaging findings, anatomy and the potential risks and benefits of each approach.
Observation & Follow-Up
Some asymptomatic or lower-risk lesions may be monitored when immediate intervention is not considered necessary.
Embolization
In selected AVMs, an endovascular procedure can be used to reduce or block abnormal blood flow by delivering an embolic material through a catheter.
Surgical Treatment
Surgical removal or another operative approach may be considered for selected lesions when anatomy and clinical factors make it appropriate.
Combined Treatment
Some complex AVMs may require a staged or combined approach, such as embolization followed by another treatment.
Location-Specific Care
AVMs involving the brain, spinal cord or other specialised anatomical areas may require referral and multidisciplinary management appropriate to that location.
Long-Term Monitoring
Follow-up may be recommended after treatment to evaluate symptoms, blood-flow changes and whether additional treatment is needed.
Endovascular Care
AVM Embolization
Embolization is a minimally invasive technique used in selected vascular malformations to alter or reduce abnormal blood flow.
Access
A small catheter is introduced into the vascular system and guided toward the vessels supplying the malformation.
Imaging Guidance
Real-time imaging helps the treating team understand the vascular anatomy and position the catheter appropriately.
Embolic Material
A suitable embolic agent may be delivered in selected cases to reduce or block abnormal blood flow.
Post-Treatment Assessment
Imaging and clinical follow-up help assess the response and determine whether further treatment or monitoring is required.
Embolization is not suitable for every AVM.
The choice of embolic technique and whether embolization should be used alone or with another treatment depends on the lesion's anatomy, flow pattern, location and overall clinical situation.
Specialist Vascular Care
Why Consider Specialist AVM Evaluation?
Vascular malformations can have complex anatomy. A structured evaluation helps match treatment intensity to the individual clinical situation.
Detailed Vascular Assessment
Clinical findings and appropriate vascular imaging are reviewed before treatment decisions are made.
Endovascular Expertise
Selected vascular malformations may be considered for catheter-based treatment when the anatomy is appropriate.
Individualised Planning
Treatment recommendations are based on the location, size, flow characteristics, symptoms and imaging findings of each lesion.

Frequently Asked Questions
AVM Treatment FAQs
Common questions about arteriovenous malformations, diagnosis and treatment.
What is an arteriovenous malformation?
An AVM is an abnormal connection between arteries and veins that bypasses the normal capillary network. AVMs can occur in different parts of the body.
What symptoms can an AVM cause?
Symptoms depend on the location and characteristics of the AVM and may include pain, swelling, skin changes, pulsation, bleeding or other location-specific symptoms.
How is an AVM diagnosed?
Depending on the lesion, evaluation may include clinical examination, Doppler ultrasound, CT, MRI and angiography to understand the vascular anatomy and blood-flow pattern.
Can an AVM be treated without open surgery?
Selected AVMs may be treated using endovascular techniques such as embolization. Whether this is appropriate depends on the lesion's anatomy, location and flow characteristics.
Is embolization suitable for every AVM?
No. Embolization is not appropriate for every vascular malformation. A specialist evaluates the imaging and clinical findings before recommending an endovascular approach.
Can an AVM come back after treatment?
The possibility of residual or recurrent abnormal vessels depends on the type, location and treatment of the AVM. Follow-up is therefore important when recommended by the treating team.
Are all AVMs dangerous?
Risk varies considerably between AVMs. The potential complications depend on location, size, blood-flow characteristics, symptoms and other individual factors.
When should I seek urgent care?
Sudden severe symptoms, significant bleeding, loss of consciousness, sudden neurological changes or rapidly worsening symptoms require immediate medical assessment.
Where can I get AVM evaluation in Hyderabad?
Hyderabad Vascular Center provides specialist vascular evaluation and treatment planning. The appropriate pathway depends on the location and characteristics of the vascular malformation.
Need Evaluation for an Arteriovenous Malformation?
If you have a known AVM, an unexplained vascular swelling, abnormal pulsation, recurrent bleeding or imaging findings suggesting a vascular malformation, specialist assessment can help determine the next step.
