Real-Time Visualization for Brain & Spinal Cord Injury Treatment

Intraoperative Neuromonitoring & Neuronavigation Techniques at Medanta Hospital, Lucknow

What is Intraoperative Neuromonitoring & Neuronavigation?

Intraoperative Neuromonitoring (IOM) is a real-time technique that continuously monitors the functional integrity of the nervous system during surgery. It uses electrophysiological methods to detect changes in neural function and alert surgeons to potential nerve damage before it becomes permanent.

Neuronavigation is an advanced imaging-guided surgical technique that provides real-time, 3D visualization of the operative field. It uses pre-operative CT/MRI scans to create a precise map, allowing surgeons to navigate complex anatomical structures with submillimeter accuracy.

Who Needs Neuronavigation & Monitoring?

These techniques are essential for patients with:Brain tumors (especially near critical functional areas)Spinal cord tumors and lesions.Traumatic brain injuries requiring surgical intervention. Spinal cord compression causing neurological deficits. Vascular malformations (AVMs, aneurysms)Tethered spinal cordPatients with cervical myelopathy or stenosisSyrinx (fluid accumulation in spinal cord)Any condition where preserving neurological function is critical

Understanding Brain AVM

How are These Techniques Performed?

Intraoperative Neuromonitoring:

Pre-operative Setup: Electrodes are placed on the patient’s scalp and limbs under anesthesia.Baseline Recording: Initial neural signals are recorded before surgery begins

Continuous Monitoring: Throughout surgery, signals are continuously recorded from motor pathways (spinal tracts), sensory pathways, and cranial nerves

Real-time Analysis: Neurophysiologists analyze waveforms and alert surgeons to any significant changes (>50% amplitude reduction or increased latency indicates risk)

Intra-operative Adjustments: Surgeons modify technique if warning signs appear

Neuronavigation:

  • Pre-operative Planning: High-resolution MRI/CT scans are acquired

    Image Registration: Patient’s anatomy is registered into the navigation system

    3D Reconstruction: Computer creates a 3D map of tumor, blood vessels, and vital structures

    Intra-operative Tracking: A tracked pointer/microscope shows the surgeon’s exact position relative to pre-operative imaging

    Real-time Guidance: Surgeons follow a planned surgical corridor, minimizing damage to healthy tissue

Why Choose Our Centre for AVM Treatment in Lucknow?

Brain AVM treatment requires a rare combination of skills: endovascular expertise, microsurgical mastery, and radiosurgical precision. We offer all this under one roof.

  • Cerebrovascular Sub-Specialisation: Dr. Kamlesh Singh Bhaisora possesses focused expertise in the surgical and endovascular management of complex brain AVMs. His training and experience ensure that these high-risk lesions are treated with the highest standard of care.
  • Multimodal Treatment Capability: We do not believe in a single approach for all. We offer the full spectrum:
  • Endovascular Embolisation: Minimally invasive glue or coil placement to block feeding arteries.
  • Microsurgical Resection: Complete removal of the AVM through precision microsurgery.
  • Stereotactic Radiosurgery (CyberKnife VSI): Non-invasive radiation for small, deep, or inoperable AVMs.
  • Advanced Imaging & Planning: We use high-resolution cerebral angiography, CTA, MRA, and 3D rotational angiography to map every detail of your AVM, its size, location, feeding arteries, and draining veins before planning treatment.
  • Dedicated Neuro ICU: Post-treatment care is critical. Our intensivist-led Neuro ICU provides 24/7 monitoring for complications like cerebral edema, re-bleeding, or vasospasm.
  • Proven Track Record: With extensive experience managing complex cerebrovascular cases, our centre is a trusted destination in Lucknow for AVM treatment.

Our Advanced AVM Treatment Modalities

We tailor the treatment to your specific AVM using a multidisciplinary approach.

Endovascular Embolisation (Minimally Invasive)

  • The Procedure: A microcatheter is threaded from an artery in the groin up to the brain. A liquid embolic agent (glue or Onyx) is injected to block the abnormal vessels feeding the AVM.
  • Purpose: Can cure small AVMs alone, reduce the size of large AVMs before surgery or radiosurgery, or target dangerous components like aneurysms.
  • Recovery: Typically 1-2 days in hospital; minimally invasive with no cranial incision.

Microsurgical Resection (Open Surgery)

  • The Procedure: Under an operating microscope, Dr. Bhaisora performs a craniotomy to access the brain, meticulously dissects around the AVM, and removes it completely while preserving normal blood vessels and brain tissue.
  • When Used: For AVMs that are small to moderate in size, located in non-eloquent (non-critical) brain areas, or after embolisation has reduced blood flow.
  • Cure Rate: Approaches 95-100% for appropriately selected AVMs when completely resected.

Stereotactic Radiosurgery (CyberKnife VSI)

  • The Procedure: Highly focused radiation beams are precisely targeted at the AVM. Over 1-3 years, the blood vessels gradually thicken and close off.
  • When Used: For small AVMs (<3 cm), located deep or in eloquent brain areas where surgery carries high risk.
  • Success Rate: 70-85% obliteration rate at 2-3 years, with low risk of complications.

Combined (Staged) Approach

  • Embolisation + Surgery: To reduce blood flow before resection, making surgery safer.
  • Embolisation + Radiosurgery: To shrink the AVM size so radiosurgery becomes effective.
  • Radiosurgery after Partial Embolisation: To treat residual nidus.

Frequently Asked Questions (FAQs)

Q. Best treatment for a brain AVM?
No single “best” treatment exists, it depends on the AVM’s size, location, and rupture status. Endovascular embolisation, microsurgery, and radiosurgery are complementary tools. Our team recommends a personalised plan, often combining two or more modalities.
Yes. Microsurgery offers a complete cure if the entire nidus is removed. Radiosurgery achieves obliteration over 1–3 years. Embolisation alone can cure small AVMs but is often a bridge to surgery or radiosurgery for larger ones.
For low-grade AVMs (Grade I–II), the microsurgery cure rate exceeds 95%. For complex, high-grade AVMs, our multidisciplinary approach focuses on reducing rupture risk through staged procedures.
Risks include bleeding, stroke, or neurological deficit, but these are generally lower than the lifetime rupture risk, especially in young patients. Dr Bhaisora’s expertise minimises these risks with meticulous planning.
Dr. Bhaisora calculates your AVM’s annual rupture risk based on size, deep drainage, and associated aneurysms. For unruptured, low-risk AVMs, observation may be appropriate. For high-risk or ruptured AVMs, treatment is strongly recommended.
