Venous Sinus Stenting

Venous Sinus Stenting Procedure in Kanakapura Road

When headaches keep returning, vision starts to blur, and ordinary painkillers stop helping, it is easy to feel stuck in a cycle with no clear exit. That is often the point where people begin looking beyond symptom relief and toward the real cause. Venous sinus stenting is designed for patients whose symptoms are linked to raised pressure inside the skull, especially when a narrowed venous sinus is blocking smooth blood drainage from the brain. At Manipal Hospital, the focus is not just on placing a stent, but on understanding the pressure problem behind it and choosing the right patient for treatment. Venous sinus stenting in Kanakapura Road, Bangalore, may be considered when imaging and pressure studies show a meaningful narrowing that is driving the illness.

How It Works

Venous sinus stenting is most often used in people with Idiopathic Intracranial Hypertension, or IIH, a condition where pressure inside the skull rises without a clear mass or bleed causing it. Many of these patients also have narrowing in one of the large venous sinuses that drain blood away from the brain. That narrowing can create a bottleneck, which keeps pressure high and makes symptoms persist.

The process starts with a careful workup. Patients usually undergo detailed brain imaging, along with venous imaging that shows the blood flow pathways. In selected cases, a catheter-based pressure study is done to measure whether the narrowing is actually causing a significant gradient. That detail matters because not every narrowing needs a stent. The decision is based on symptoms, imaging, and pressure findings together.

If the team confirms that the narrowing is clinically important, a self-expanding stent is placed through a minimally invasive endovascular approach. The stent props open the narrowed venous channel, improve drainage from the brain, and lower pressure over time. For many patients, this means fewer headaches, better visual stability, and a stronger chance of protecting long-term brain and eye health.

Benefits

For patients with IIH and a significant venous sinus stenosis, stenting offers a targeted solution. Key benefits include:

  • Immediate reduction in the pressure gradient across the narrowed sinus, restoring normal venous outflow

  • Significant improvement in headaches, often within days to weeks after the procedure

  • Stabilisation or improvement of vision, reducing the risk of permanent vision loss

  • Reduction or elimination of the need for acetazolamide or other medications with difficult side effects

  • Avoidance of shunt surgery in carefully selected patients

  • A minimally invasive approach with no incision on the scalp and no brain manipulation

What to Expect

From the first diagnostic workup through recovery, our team ensures that patients and families understand why each step matters.

Initial Evaluation and Venous Imaging

When IIH is suspected, we start with MR or CT venography to look for venous sinus stenosis. If a narrowing is seen, we discuss the next step. The goal is to determine whether the narrowing is causing the pressure or is simply an incidental finding.

Diagnostic Venography and Pressure Measurement

Under sedation, we perform a formal venogram and measure pressures across the narrowing. This is the definitive test. It tells us whether stenting will help. Families receive updates during the procedure.

Stenting Procedure

If the pressure gradient is significant, we proceed with stent placement. A self-expanding stent is deployed across the narrowed segment. The pressure is measured again to confirm success. The procedure typically lasts one to two hours.

Post-Procedural Monitoring

After the procedure, the patient is monitored closely. Antiplatelet medications are started. Blood pressure is managed. Most patients stay in the hospital for one to two days before discharge.

Recovery and Follow-Up

Headache improvement often begins within days. Vision changes may take weeks to show improvement. We schedule follow-up imaging to confirm the stent is patent. Ongoing management includes antiplatelet therapy and coordination with neurology and ophthalmology.

Why Manipal Hospital Kanakapura Road

Idiopathic intracranial hypertension is a condition where the pressure inside the skull rises too high. For a subset of these patients, the problem lies in the veins that drain blood from the brain. They narrow, creating a bottleneck. The pressure builds behind that narrowing. At Manipal Hospital Kanakapura Road, we have developed a systematic approach to identifying who will benefit from stenting and delivering it safely. Families choose us for venous sinus stenting in Kanakapura Road, Bangalore, because of the following reasons: 

  • A rigorous diagnostic pathway that begins with dedicated imaging to identify venous sinus stenosis, followed by formal venography and pressure measurements to confirm a significant gradient before any stent is placed

  • Access to a high-resolution bi-plane angiography suite with venous pressure monitoring capabilities, allowing us to measure the pressure difference across the narrowing with precision

  • An Interventional Neuroradiology team with specialised experience in navigating the cerebral venous sinuses, understanding the variants of venous anatomy, and deploying self-expanding stents in a space that demands patience

  • Close collaboration with neuro-ophthalmology to track vision, with neurology to manage headaches, and with neurosurgery to ensure that stenting is offered only when it is the right fit

  • Staged management for patients with bilateral stenosis or those who may need additional procedures, ensuring that each step is guided by what the pressure measurements show

FAQ's

Yes, the stent is designed to remain in place long-term. You will need to take antiplatelet medications, typically aspirin and another medication, for a period of time to keep the stent open.

Candidates are patients with IIH who have a significant pressure gradient across a narrowed venous sinus. We perform diagnostic venography with pressure measurements to confirm this before proceeding.

Many patients notice significant improvement in headaches within days to weeks. The timeline varies. Some experience immediate relief, while others improve more gradually as the pressure normalises.

Risks include vessel injury, stent thrombosis, restenosis, and complications related to antiplatelet medications. Our team minimises these through careful patient selection and meticulous technique.

Yes, this is a recognised procedure for IIH with documented venous sinus stenosis and a significant pressure gradient. Our team can help verify coverage before scheduling.
