Best AV Malformation Procedure at Affordable Cost at Medicover

Arteriovenous Malformation (AVM) surgery is a medical procedure performed to treat a vascular abnormality known as an arteriovenous malformation. AVM, short for arteriovenous malformation, is an uncommon condition characterized by an abnormal tangle of blood vessels that connect arteries and veins. This tangled network disturbs the regular blood flow and can result in severe health complications, including bleeding, seizures, or neurological deficits.


Indications of AV Malformation Surgery

Arteriovenous malformation surgery is indicated for patients who have been diagnosed with an arteriovenous malformation and are experiencing symptoms or are at risk of potential complications related to the abnormal vascular condition. The main indications for AVM surgery include:

  • Symptomatic AVM: Surgery is recommended for patients with symptomatic AVMs, where the abnormal blood flow leads to neurological symptoms, such as seizures, headaches, weakness, numbness, or other neurological deficits.
  • Recurrent Bleeding: If the AVM has previously bled and poses a high risk of recurrent bleeding, surgery may be indicated to prevent life-threatening hemorrhages.
  • Progressive Neurological Deficits: AVMs that cause progressive neurological deficits or impair the patient's quality of life may require surgical intervention.
  • Inoperable AVMs: In some cases, embolization or radiosurgery (gamma knife) may not be feasible or effective, making open surgical resection the preferred treatment option.
  • Presence of High-Flow Shunts: AVMs with high-flow shunts and increased risk of complications may require surgical correction.

Steps involved in AV Malformation Surgery

These tangles can disrupt normal blood flow and potentially lead to serious complications, including bleeding and neurological symptoms. Here are the general steps involved in AVM surgery:

  • Preoperative Evaluation: The patient undergoes a thorough medical evaluation, including imaging tests such as MRI, CT angiography, or cerebral angiography, to accurately assess the location, size, and characteristics of the AVM.
  • Consultation and Informed Consent: The patient meets with the neurosurgeon to discuss the procedure, its risks, benefits, and potential alternatives. Informed consent is obtained after the patient fully understands the treatment plan.
  • Anesthesia: The patient is positioned on the operating table, and anesthesia is administered to ensure they are unconscious and pain-free during the surgery. General anesthesia is typically used.
  • Skull Opening (Craniotomy): A section of the skull is carefully removed to access the brain. The size and location of the bone flap depend on the AVM's location.
  • Exposure of the AVM: The neurosurgeon gently moves aside the brain tissues to access the AVM while minimizing damage to healthy brain tissue.
  • Disconnection of Blood Vessels: The surgeon identifies the abnormal blood vessels that make up the AVM and carefully disconnects them from the surrounding healthy tissue. This involves meticulous dissection and separation of the abnormal vessels.
  • Controlled Bleeding and Hemostasis: Bleeding from disconnected vessels is controlled using specialized surgical techniques, including cauterization, sutures, or tissue-sealing agents.
  • Closure and Reattachment of Skull Flap: The bone flap is repositioned and secured with plates, screws, or other fixation devices. This step restores the protective covering of the brain.
  • Closure of Tissues: The layers of tissue and muscles are closed with sutures, and the surgical site is covered with sterile dressings.
  • Recovery and Observation: The patient is taken to a recovery area, where they are closely monitored as they wake up from anesthesia. Vital signs are checked, and pain management measures are implemented.
  • Postoperative Care and Hospital Stay: The patient's condition is monitored in the hospital's intensive care unit or a specialized neurosurgical unit. The length of hospital stay can vary based on the patient's condition and the complexity of the surgery.
  • Rehabilitation and Follow-Up: After discharge, the patient may need physical therapy and rehabilitation to regain strength, coordination, and mobility. Follow-up appointments are scheduled to monitor the healing process, assess neurological function, and address any concerns.

Who will Treat for AV Malformation Surgery:

Arteriovenous Malformation (AVM) surgery is a complex and specialized procedure that requires the expertise of skilled healthcare professionals. Patients who need AVM surgery should contact and seek consultation from a team of medical specialists with experience in treating AVMs.

  • Neurosurgeon: Neurosurgeons are medical doctors who specialize in the surgical treatment of conditions affecting the brain, spinal cord, and nervous system. They are the primary specialists responsible for performing AVM surgery.
  • Interventional Radiologist: Interventional radiologists are medical doctors who use minimally invasive techniques, such as catheter-based procedures, to diagnose and treat a variety of vascular conditions, including AVMs. In some cases, an interventional radiologist may perform embolization before or in conjunction with surgery.
  • Neurologist: Neurologists are medical doctors who specialize in the diagnosis and non-surgical management of neurological disorders. They may be involved in the preoperative evaluation and postoperative care of patients with AVMs.
  • Neuroradiologist: Neuroradiologists are radiologists with specialized training in interpreting imaging studies of the brain and nervous system. They play a crucial role in diagnosing and characterizing AVMs using imaging techniques such as angiography and MRI.
  • Neuroanesthesiologist: Neuroanesthesiologists are anesthesiologists with expertise in providing anesthesia for neurosurgical procedures, including AVM surgery. Their focus is on ensuring patient safety and comfort during surgery.
  • Neuropsychologist: Neuropsychologists may be involved in assessing cognitive function and potential neurological deficits before and after surgery, especially if the AVM is located in critical brain regions.
