STROKE: Every Minute Matters. Every Second Saves Brain. 🧠⏱️

Mechanical thrombectomy has revolutionized the treatment of acute ischemic stroke due to large-vessel occlusion, making it possible to rapidly remove the clot and restore blood flow in appropriately selected patients.

With Dr. Nirmalya Ray’s expertise in mechanical thrombectomy, supported by the advanced infrastructure and comprehensive stroke-care network of Manipal Hospitals across Kolkata, patients have access to cutting-edge stroke treatment when time matters most. With the support from our neurology colleagues, Cathlab technicians and nursing staffs, these cases could be performed.

Recognize stroke early. Reach the right centre fast. Restore blood flow. Save brain.

A Minimally Invasive Solution for a Giant Liver Hemangioma

Sharing a successfully treated case of a symptomatic giant liver hemangioma involving segment VI of the liver.

The patient presented with persistent right hypochondrial pain and underwent endovascular embolization using Bleomycin-TACE. Selective catheter-based treatment resulted in complete embolization of the lesion, followed by significant symptomatic relief after the procedure.

This case highlights how Interventional Radiology can provide effective, minimally invasive treatment options for selected vascular liver lesions—often avoiding the need for major surgery.

Complex Ruptured Brain Aneurysm Successfully Treated with Flow Diverter-Assisted Coiling

This patient suffered a subarachnoid hemorrhage while in visiting his son in Canada approximately 3 weeks prior to presentation. Following initial stabilization, the patient amd family returned to Kolkata to continue definitive treatment, placing their trust in the expertise of doctors in Bengal.

Cerebral angiography revealed a subacutely ruptured left paraophthalmic internal carotid artery aneurysm. After careful evaluation and treatment planning, the aneurysm was successfully treated using flow diverter-assisted coiling at Manipal Hospitals, Mukundapur in the advanced neurovascular biplane cathlab. Patient was discharged within 2 days of the procedure.

The images demonstrate:
• Diagnostic angiography showing the aneurysm .
• 3D rotational angiography for procedural planning
• Endovascular placement of the flow diverter with adjunctive coil embolization • Cone Beam CT confirming flow diverter and coil in situ
• Final angiographic result demonstrating successful aneurysm exclusion with preservation of the parent artery.

Modern endovascular techniques such as flow diversion have significantly expanded the treatment options for complex intracranial aneurysms, offering durable aneurysm occlusion while preserving normal cerebral blood flow.

A TIA (Mini-Stroke) is a Warning Sign You Cannot Ignore! 🛑

A Transient Ischemic Attack (TIA) is a powerful, though often subtle, warning of a potential full-blown stroke. For patients with serious carotid artery blockage, immediate and precise action is critical.

​Swipe ➡️ to see how Dr. Nirmalya Ray (Senior Consultant Neurointerventionist) at Manipal Hospitals, Mukundapur, successfully treated a case of recurrent TIA using advanced and minimally invasive Carotid Stenting.

​Through this minimally invasive procedure, we are not just treating symptoms; we are actively preventing future strokes by restoring critical blood flow to the brain.

​Highlights of this case:
✅ Pre-Stenting: A critical narrowing (stricture) is visible.
✅ Balloon Angioplasty: The artery is prepared for the stent.
✅ Final Result: Restored, wide-open flow with a secure stent structure in place.

Right carotid stenting done for a patient from far mizoram who had a prior minor stroke. Carotid stenting is a minimally invasive procedure where angioplasty of the narrowed neck vessel is done followed by putting a stent under filter device protection to prevent peripricedural stroke. The aim is to increase blood flow to the brain and prevent future major disabling stroke.

This patient came to us from Jamshedpur in a comatose state. He was found to have diffuse subarachnoid hemorrhage with intraventricular hemorrhage due to ruptured Right Vertebral artery dissecting aneurysm, which was treated using flow diverter stent and patient made a complete neurological recovery far from our expectation. The entire procedure was done through a pinhole in groin without cutting the skull. The procedure was done at Manipal Hospitals, Kolkata.
