Arteriovenous Malformation (AVM) Surgery

Brain AVM Arteriovenous Malformation In Kolkata

Arteriovenous malformation (AVM) surgery is a complex procedure performed to treat abnormal tangles of blood vessels in the brain or spinal cord. AVMs consist of arteries and veins that are abnormally connected, bypassing the capillary system. This abnormality can lead to weakened blood vessel walls and an increased risk of rupture, potentially causing haemorrhage, stroke, or neurological deficits. The goal of AVM surgery is to remove or obliterate the malformation, thereby eliminating the risk of bleeding and reducing symptoms associated with the AVM, such as seizures or neurological deficits. The decision to undergo surgery depends on factors such as the size, location, and accessibility of the AVM, as well as the patient's overall health and neurological status.

During AVM surgery, a neurosurgeon carefully removes the abnormal blood vessels while preserving the surrounding healthy brain tissue. This may involve accessing the AVM through a Craniotomy (opening in the skull) or using minimally invasive techniques such as endovascular embolisation or radiosurgery. Close monitoring and postoperative care are essential to ensure optimal recovery and minimise complications.

FAQ's

The exact cause of AVMs often remains unknown. While some are congenital, appearing at birth, others may develop later due to genetic mutations, environmental factors like radiation exposure, or hormonal changes, especially during puberty or pregnancy.

Symptoms can vary widely based on the AVM's location and size. Along with headaches, seizures, and neurological deficits, patients might experience cognitive impairments, speech difficulties, or even paralysis. Some may also report tinnitus, vision changes, or dizziness.
 

Diagnosis involves a combination of imaging studies. Magnetic Resonance Angiography (MRA), Digital Subtraction Angiography (DSA), and CT perfusion scans can provide detailed images of blood flow, identify AVMs, and assess their impact on surrounding brain tissue.
 

Surgery is considered for symptomatic AVMs, those with a high risk of rupture or haemorrhage, or when other treatments aren't effective. The decision also considers the AVM's location, size, the patient's age, and overall health. Pediatric patients or those with multiple AVMs might require more conservative approaches.

In addition to bleeding, infection, and damage to surrounding structures, potential risks include seizures, cognitive deficits, and stroke. The risks vary depending on the AVM's complexity, location, the patient's age, and overall health. Some procedures might carry a risk of cerebrospinal fluid leakage or hydrocephalus.
 

Arteriovenous Malformation (AVM) surgery is typically performed under general anaesthesia to ensure the patient remains pain-free and immobile throughout the procedure. Surgeon using advanced imaging techniques like angiography, the surgeon identifies the abnormal tangle of blood vessels comprising the AVM.

Once the AVM is exposed, the surgeon proceeds to disconnect the abnormal blood vessels. This delicate task requires precision to prevent excessive bleeding and potential damage to surrounding structures. After disconnecting the abnormal vessels, the surgeon carefully removes the malformation. Special care is taken to minimise damage to surrounding healthy tissue, nerves, and blood vessels. In some cases, to fully remove the AVM, the surgeon may need to enter deeper structures, such as the brain or spinal cord.

Post-surgery, the patient is closely monitored in the intensive care unit or a specialized recovery ward to ensure proper healing and to manage any potential complications. Physical and occupational therapy may be recommended to help the patient regain strength and function, especially if the AVM was located in a critical area affecting movement or coordination.
 

Post-surgery, patients often require intensive care monitoring and rehabilitation. Recovery can range from several weeks to months, with physical therapy playing a crucial role in restoring function. Some patients might experience fatigue, mood swings, or cognitive changes during the recovery phase.
 

While many patients experience symptom relief and reduced risk of complications post-surgery, long-term outcomes can vary. Some may require ongoing treatment or experience residual symptoms. Regular follow-up care, including imaging and neurological assessments, is essential for monitoring potential complications and ensuring optimal outcomes.
 

Before surgery, comprehensive evaluations including imaging, blood tests, neuropsychological assessments, and consultations with specialists ensure the patient's overall health. Preoperative embolization might be considered in some cases to reduce blood flow to the AVM and minimise surgical risks.
 

Success is gauged by various factors, including symptom improvement, reduced AVM size or blood flow, and patient satisfaction. Follow-up imaging and assessments are crucial for evaluating long-term outcomes. Functional outcomes, such as improved quality of life, cognitive function, and mobility, also play a significant role in determining success.
 

The risk of recurrence is influenced by factors like the completeness of AVM removal, its location, size, and individual patient factors. Regular monitoring and imaging help detect any recurrence early for timely intervention. Some patients might require lifelong follow-up to monitor for potential complications or new AVM formations.
