Neurointerventional Services: Visiting Consultant Program

Heart and Vascular Center, Victoria Hospital, Yangon

Bringing world-class cerebrovascular interventions to Myanmar through specialized expertise and advanced techniques.

Visiting Consultant

Dr. Sai Kanth Reddy

Interventional Neuroradiologist

Bengaluru, India

Visit Dates: August 15-17, 2025

Dr. Reddy specializes in minimally invasive treatments for complex cerebrovascular disorders, having performed over 5000 successful interventions.

His expertise encompasses aneurysm management, stroke treatment, and vascular malformation procedures.

Available Neurointerventional Procedures

Cerebrovascular Interventions

Aneurysm Management

Coil embolization: Platinum coils placed within aneurysm to induce thrombosis

Stent-assisted coiling: Stent provides structural support for complex aneurysms

Balloon-assisted coiling: Temporary balloon inflation stabilizes coil placement

Flow diverter placement: Redirects blood flow away from aneurysm neck

These minimally invasive techniques provide alternatives to conventional neurosurgery, reducing recovery time and procedural risks for appropriate candidates.

Stroke Interventions

Our visiting consultant program brings advanced stroke intervention capabilities to Yangon, providing crucial time-sensitive treatments for eligible patients.

Available Procedures:

Carotid artery stenting: Endovascular treatment for significant stenosis causing TIAs or strokes

Intracranial atherosclerotic disease (ICAD) stenting: Targeted treatment for narrowed cerebral vessels resistant to medical management

These interventions significantly reduce stroke recurrence risk in properly selected patients with specific anatomical features and clinical presentations.

Carotid stenting can reduce stroke risk by restoring normal blood flow to the brain.

Vascular Malformation Treatment

Arteriovenous Malformation (AVM) Embolization

Staged endovascular occlusion of feeding arteries using liquid embolic agents (Onyx, nBCA) to reduce bleeding risk and facilitate subsequent surgical resection when appropriate.

Arteriovenous Fistula (AVF) Embolization

Direct occlusion of abnormal arteriovenous connections using coils, liquid embolics, or vascular plugs to eliminate shunting and prevent neurological deterioration.

Spinal Dural AVF/AVM Embolization

Precise endovascular navigation to treat spinal vascular malformations causing myelopathy, radiculopathy, or hemorrhage risk with specialized microcatheters and embolic materials.

Specialized Interventions

Venous Disorders

Cerebral venous thrombosis can cause severe neurological deficits if left untreated.

Cerebral Venous Thrombosis (CVT)

Interventions

Endovascular thrombolysis and mechanical thrombectomy for patients with deteriorating neurological status despite anticoagulation.

Transverse Sinus Stenting

Precision stent placement for idiopathic intracranial hypertension (IIH) with venous sinus stenosis, providing immediate pressure gradient reduction and symptom relief.

These specialized interventions address rare but potentially devastating cerebrovascular conditions that may not respond to conventional medical management.

Tumor Embolization

Pre-surgical Meningioma

Embolization

Devascularization of hypervascular meningiomas 24-48 hours before surgical resection, reducing intraoperative blood loss by up to 70% and facilitating complete tumor removal.

Juvenile Nasopharyngeal

Angiofibroma Embolization

Preoperative embolization of feeding vessels from external carotid artery branches, minimizing surgical hemorrhage risk in these highly vascular tumors affecting adolescent males.

Vertebral Body Hemangioma

Embolization

Direct puncture or transarterial embolization of symptomatic vertebral hemangiomas causing pain or neurological symptoms from spinal cord compression.

Other Procedures

Middle Meningeal Artery (MMA) Embolization

Innovative treatment for chronic subdural hematomas, particularly in elderly or anticoagulated patients. This procedure targets the pathological vascular membranes responsible for hematoma expansion, providing an alternative to surgical drainage.

Clinical outcomes show 70-80% resolution rates without craniotomy, significantly reducing recurrence compared to conventional surgery.

Diagnostic Cerebral and Spinal Angiography (DSA)

High-resolution vascular imaging providing definitive assessment of:

Aneurysm morphology and dimensions

AVM angioarchitecture and flow dynamics

Collateral circulation in occlusive disease

Vasospasm following subarachnoid hemorrhage

Case Referral Criteria

Urgent Cases

Ruptured Intracranial Aneurysms

Hunt & Hess grade 1-3 subarachnoid hemorrhage patients with aneurysms amenable to endovascular treatment.

Early intervention (within 72 hours) significantly reduces rebleeding risk and improves neurological outcomes.

Acute Cerebral Venous Thrombosis

Patients with extensive dural sinus thrombosis, worsening despite therapeutic anticoagulation, particularly those with altered mental status, focal deficits, or intracranial hemorrhage.

High-flow AVMs with Hemorrhage Risk

Arteriovenous malformations with flowrelated aneurysms, venous stenosis, or deep venous drainage patterns indicating elevated rupture risk. Targeted embolization can stabilize high-risk features.

Elective Cases

Success Rate

For unruptured aneurysm occlusion with modern endovascular techniques

Eligible Elective Cases

Stroke Reduction

In symptomatic carotid stenosis patients receiving appropriate intervention

Recurrence Prevention

For chronic subdural hematomas treated with MMA embolization vs. surgery alone

Unruptured aneurysms suitable for endovascular treatment based on location, morphology, and neck-to-dome ratio

Symptomatic carotid stenosis >70% or asymptomatic >80% with favorable anatomy for stenting

Intracranial stenosis >70% with recurrent strokes despite optimal medical therapy

Chronic subdural hematoma candidates for MMA embolization with recurrent collections or high surgical risk

Pre-surgical Embolization

Hypervascular Tumors

Ideal candidates for pre-surgical embolization include:

Meningiomas >3cm with significant external carotid artery supply

Juvenile nasopharyngeal angiofibroma (JNA) in adolescent males with extensive vascularity

Paragangliomas of the head and neck region

Embolization is typically performed 24-48 hours before planned surgical resection to maximize benefit while avoiding revascularization.

Vertebral Body Hemangiomas

Considered for embolization when presenting with:

Progressive painful symptoms

Pathological fracture risk

Epidural extension causing cord compression

Planned surgical stabilization

Patient Selection Guidelines

Aneurysm Cases

Size & Morphology

Aneurysm dimensions, neck width, dometo-neck ratio, and presence of daughter sacs impact treatment approach.

Imaging Quality

High-resolution CTA/MRA/DSA studies are essential for appropriate treatment planning.

Location

Anatomical position affects device selection and technical approach (e.g., sidewall vs. bifurcation).

Patient Factors

Age, comorbidities, antiplatelet tolerance, and prior treatments influence risk-benefit assessment.

Stroke Prevention

Carotid ultrasound showing >70% stenosis (left)

compared to normal flow (right)

Carotid Stenosis Criteria

Symptomatic stenosis >70% with recent TIA or minor stroke

Asymptomatic stenosis >80% with high-risk plaque features

Contralateral occlusion increasing hemodynamic significance

Favorable arch anatomy for endovascular access

Intracranial Stenosis Criteria

Stenosis >70% with recurrent events despite aggressive medical therapy

Absence of perforator-rich segments reducing procedural risk

Complete imaging workup including vessel wall MRI to characterize plaque

Good distal vascular bed with limited chronic ischemic change

AVM/AVF Case Selection

Spetzler-Martin Grading

Comprehensive AVM evaluation using established grading system that incorporates:

Size (<3cm, 3-6cm, >6cm)

Venous drainage pattern (superficial vs. deep)

Eloquence of adjacent brain regions

Grades 1-3 typically considered for intervention, while grades 4-5 require individualized multidisciplinary approach.

Eloquent Location Assessment

Functional MRI and tractography to determine proximity to:

Primary motor/sensory cortex

Language areas

Visual cortex

Hypothalamus, thalamus, brainstem

Hemorrhage History

Prior hemorrhage significantly impacts management decisions:

Increases annual rebleed risk (4-8% vs. 1-3%)

May identify specific angioarchitectural risk factors

Often lowers threshold for intervention
