Arteriovenous Malformation (AVM) Resection Surgery in Turkey
Understanding Arteriovenous Malformations (AVMs)
Arteriovenous malformations (AVMs) occur when abnormal direct connections form between arteries and veins without the presence of capillaries, disrupting the normal process of gas and nutrient exchange. Under normal physiological conditions, arteries carry oxygen-rich and nutrient-rich blood from the heart to body tissues, while veins return deoxygenated blood containing carbon dioxide back to the heart and lungs. Capillaries serve as the intermediary network where the exchange of oxygen, nutrients, and waste products takes place.
Blood normally circulates through a highly organized and closed vascular system. In individuals with AVMs, the capillary network is absent or significantly reduced, resulting in a direct connection between high-pressure arterial blood flow and veins that are not designed to withstand such pressure. Over time, this abnormal hemodynamic stress may weaken the blood vessels, increasing the risk of rupture and potentially life-threatening bleeding.
There are two main types of arteriovenous malformations:
Cerebral Arteriovenous Malformations (Brain AVMs)
These are the most common and potentially the most dangerous type, occurring within brain tissue.
Peripheral Arteriovenous Malformations
These may develop in the face, limbs, or internal organs such as the liver and lungs.
Overall, AVMs are considered serious vascular abnormalities that may become life-threatening if left untreated. AVM resection surgery in Turkey represents one of the most effective treatment options available, offering advanced neurosurgical expertise and modern medical technology.
What Is AVM Resection Surgery in Turkey
AVM resection surgery is an open neurosurgical procedure performed to remove abnormal blood vessels in the brain characterized by an irregular tangle of arteries and veins. The primary goal of the surgery is to prevent hemorrhage and reduce the risk of neurological complications such as seizures and neurological deficits.
During the procedure, the neurosurgeon creates an opening in the skull (craniotomy) to access the affected area of the brain. High-powered operating microscopes and advanced microsurgical techniques are used to precisely identify and remove the AVM while preserving surrounding healthy brain tissue. The feeding arteries and draining veins are carefully managed to minimize the risk of bleeding during recovery.
Indications for AVM Resection Surgery in Turkey
Brain AVMs are typically congenital abnormalities, meaning they are present at birth. However, many individuals remain asymptomatic for years. AVMs may be discovered incidentally during diagnostic imaging studies such as CT scans or MRI examinations, or after the onset of symptoms.
Common warning signs and symptoms include:
- Cognitive impairment or confusion
- Recurrent headaches, sometimes accompanied by dizziness
- Difficulty concentrating and memory disturbances
- Numbness, tingling, or localized pain
- Weakness in the arms or legs
- Impaired coordination and balance
- Epileptic seizures
- Vision problems
- Speech and language difficulties
When one or more of these symptoms are present, the possibility of a brain AVM should be considered.
Diagnostic Evaluation
To confirm the diagnosis and assess the severity of the condition, the following investigations may be performed:
- Computed Tomography (CT) scan of the brain
- Magnetic Resonance Imaging (MRI) of the brain
- Cerebral angiography using contrast dye injected through a catheter to evaluate the size and structure of the AVM
- Magnetic Resonance Angiography (MRA) with contrast enhancement to assess blood flow patterns within the brain
When imaging studies confirm the presence of a brain AVM with a significant risk of rupture or intracranial bleeding, surgical removal is often considered the most appropriate treatment option.
Preparing for AVM Resection Surgery in Turkey
Proper preparation is essential to achieve the best possible surgical outcomes. Recommended preoperative measures include:
- Comprehensive consultations between the patient, family members, and the treating physician to discuss the procedure, expected outcomes, and recovery process.
- A detailed review of the patient's medical history and current medications.
- Temporary discontinuation of blood-thinning medications such as aspirin, heparin, or enoxaparin under medical supervision before surgery to reduce bleeding risks.
- Advanced diagnostic imaging to accurately determine the location, size, and vascular anatomy of the AVM, enabling detailed surgical planning.
Steps of AVM Resection Surgery in Turkey
The procedure is generally performed according to the following steps:
General Anesthesia
The surgery is conducted under general anesthesia after confirming the patient's overall fitness for the procedure.
Craniotomy
The surgeon makes a precise incision in the scalp and temporarily removes a small section of the skull to access the brain tissue and locate the AVM.
Microsurgical AVM Removal
Using an operating microscope and specialized microsurgical instruments, the surgeon carefully isolates the AVM. The feeding arteries are typically closed first to reduce blood flow and pressure within the lesion before removing the malformation.
Preoperative Endovascular Embolization (When Necessary)
In selected cases, endovascular embolization may be performed before surgery. This technique involves injecting a specialized embolic material into targeted blood vessels to block blood flow to the AVM, thereby reducing the risk of intraoperative bleeding and improving surgical safety.
Recovery After AVM Resection Surgery in Turkey
Following surgery, patients are closely monitored to ensure a safe recovery and minimize the risk of complications.
Key postoperative recommendations include:
- Remaining hospitalized for several days for observation and neurological monitoring.
- Avoiding strenuous physical activities during the initial recovery period.
- Gradually resuming normal daily activities under medical supervision.
- Taking prescribed medications, including antiepileptic drugs when recommended.
- Following all postoperative care instructions carefully.
During the first few weeks after surgery, patients may experience:
- Mild numbness around the surgical site
- Temporary swelling
- Itching near the incision
- Swelling around the eyes
These symptoms are generally temporary and resolve gradually.
Patients should seek immediate medical attention if they develop unusual symptoms during recovery. In some cases, physical rehabilitation and physiotherapy may be recommended to support neurological recovery.
Hair typically regrows over the surgical incision within several weeks, and maintaining proper scalp hygiene is important to prevent infection.
Risks and Complications of AVM Resection Surgery in Turkey
AVM resection surgery in Turkey is performed using advanced neurosurgical technologies in highly specialized hospitals and medical centers staffed by experienced neurosurgeons and healthcare professionals. This contributes to high standards of safety and treatment effectiveness.
Nevertheless, as with any brain surgery, certain risks and side effects may occur, including:
- Headaches
- Seizures
- Fatigue
- Nausea and vomiting
- Redness, swelling, or infection at the incision site
Most of these complications are temporary and can be minimized through proper surgical planning and postoperative care.
Cost of AVM Resection Surgery in Turkey
Turkey offers advanced neurosurgical procedures, including AVM resection surgery, at highly competitive costs compared with many European countries and the United States.
The overall cost of treatment may vary depending on several factors, including:
- The type and number of preoperative diagnostic tests
- The complexity of the AVM
- The experience and expertise of the neurosurgical team
- The hospital's facilities and technological infrastructure
- The duration of hospitalization and postoperative care

Important Considerations for AVM Surgery in Turkey
Several critical factors influence the decision to perform AVM resection surgery. The location of the AVM within the brain is particularly important. Surgical treatment is generally more favorable when the lesion is located in an area that can be safely accessed without causing significant damage to critical neurological functions such as movement, speech, or vision.
In some cases, physicians may recommend preliminary treatment options, including stereotactic radiosurgery, to reduce the size of the AVM before surgical removal. This approach can improve surgical accessibility and reduce potential risks while preserving healthy brain tissue.
