Conditions
Conditions
Explore conditions affecting the blood vessels of the body, and understand the image guided treatments available for selected cases.
View all conditions →Every organ depends on blood.
When disease begins inside a vessel, treatment changes.
Image-guided intervention reaches the disease from within, preserving healthy tissue and reducing recovery wherever appropriate.
Procedures
Every procedure has its own story.
Advanced image-guided procedures are performed through a small access point, with real-time imaging guiding each step.
Procedure 01
Angioplasty & stenting
Reopening a narrowed artery from the inside.
Beat · 01
Show the narrowed artery with plaque buildup.
Beat · 02
The guidewire crosses the narrowing — the hardest millimetres of the case.
Beat · 03
The balloon is introduced and expanded to open the channel.
Beat · 04
Plaque is compressed as the balloon opens the artery.
Beat · 05
The stent is deployed and holds the artery open.
Beat · 06
Blood flow is fully restored.
Procedure 02
Mechanical thrombectomy
Removing a clot before brain tissue is lost.
Beat · 01
Imaging identifies the blocked brain vessel (Clot shown).
Beat · 02
A stent retriever is guided to the site of the clot.
Beat · 03
The retriever is deployed to capture the clot.
Beat · 04
The clot is safely removed from the brain.
Beat · 05
Angiography confirms restored blood flow.
Procedure 03
Endovascular aneurysm repair
Excluding the aneurysm from circulation.
Beat · 01
Aneurysm and blood pressure inside the sac shown (Aneurysm sac).
Beat · 02
A stent-graft is delivered to the site of the aneurysm.
Beat · 03
The graft is deployed, excluding the aneurysm sac.
Beat · 04
Blood now flows through the graft, bypassing the weak wall.
Beat · 05
Restored flow and sealed aneurysm confirmed.
Procedure 04
Endovenous laser ablation
Closing a failing vein from within.
Beat · 01
Ultrasound identifies the failing vein (Varicose vein + ulcer).
Beat · 02
A laser fiber is guided into the vein under ultrasound.
Beat · 03
Laser energy closes the diseased vein from within.
Beat · 04
Blood is rerouted to healthy deep veins.
Beat · 05
The venous ulcer begins to heal immediately.
Procedure 05
TACE — chemoembolization
Delivering chemotherapy into a tumour's own artery.
Beat · 01
Angiography identifies the liver tumour and its feeding artery.
Beat · 02
A microcatheter is precisely navigated into the feeding branch.
Beat · 03
Drug-eluting beads (treatment) are released directly into the tumour bed.
Beat · 04
The tumour blood supply is cut off by embolization.
Beat · 05
The tumour shrinks as the treatment takes effect.
Procedure 06
Microwave ablation
Destroying a tumour with heat, through a needle.
Beat · 01
Imaging identifies the liver tumour and its exact location.
Beat · 02
A needle-antenna is guided into the tumour center.
Beat · 03
Microwave energy raises the temperature inside the tumour.
Beat · 04
Heat destroys the tumour in its place.
Beat · 05
The tumour is successfully treated through a single puncture.
Procedure 07
Cerebral aneurysm coiling
Packing an aneurysm until blood no longer enters it.
Beat · 01
The cerebral aneurysm fills under pressure.
Beat · 02
A microcatheter is navigated to the neck of the sac.
Beat · 03
Soft platinum coils are packed into the aneurysm.
Beat · 04
Blood can no longer enter the sac.
Beat · 05
The treatment is completed through a single puncture.
Procedure 08
Thyroid nodule ablation
Shrinking a nodule without removing the gland.
Beat · 01
A benign nodule is mapped on ultrasound.
Beat · 02
A fine electrode enters through the skin — no incision, no scar.
Beat · 03
Energy is applied in a moving, controlled pattern.
Beat · 04
The treated tissue shrinks steadily over the following months.
Beat · 05
Thyroid function is preserved; no lifelong hormone tablets.
Procedure 09
Genicular artery embolization
Reducing the abnormal blood supply that drives knee pain.
Beat · 01
Angiography shows an abnormal blush over the inflamed knee lining.
Beat · 02
A microcatheter is advanced into the genicular branch feeding it.
Beat · 03
Microspheres are released to reduce that supply.
Beat · 04
The blush disappears under fluoroscopy.
Beat · 05
Pain improves over the following weeks. No joint is opened.
Procedure 10
Dialysis fistuloplasty
Keeping a lifeline open.
Beat · 01
Dialysis flows have fallen. A stenosis is found in the outflow vein.
Beat · 02
The fistula itself is punctured and crossed with a wire.
Beat · 03
A high-pressure balloon is inflated across the narrowing.
Beat · 04
The thrill returns under the fingertips.
Beat · 05
The same access continues to be used — no new line, no new limb.
Procedure 11
TIPS
Giving portal pressure somewhere to go.
Beat · 01
Scarred liver tissue resists the blood trying to cross it.
Beat · 02
From a neck vein, a tract is created through the liver parenchyma.
Beat · 03
A covered stent holds that tract open between portal and hepatic veins.
Beat · 04
Portal pressure falls immediately and is measured on the table.
Beat · 05
Ascites and variceal bleeding recede.
Procedure 12
Prostate artery embolization (PAE)
Shrinking the prostate by closing its supply.
Beat · 01
An enlarged prostate presses on the urethra and rules the day by the hour.
Beat · 02
A microcatheter is navigated into the prostatic arteries from a single wrist or groin puncture.
Beat · 03
Tiny particles are released, reducing blood supply to the gland.
Beat · 04
Over weeks the gland softens and shrinks, and the stream improves.
Beat · 05
Sexual function is preserved. No catheter through the urethra, no resection.
Procedure 13
Uterine fibroid embolization (UFE)
Treating fibroids without removing the uterus.
Beat · 01
Fibroids grow on a dense, abnormal blood supply of their own.
Beat · 02
Both uterine arteries are catheterised through one small puncture.
Beat · 03
Embolic particles cut off the fibroid supply while the healthy uterus keeps its own.
Beat · 04
The fibroids infarct and shrink over the following months.
Beat · 05
Bleeding settles, pressure eases, and the uterus stays.

Illustrates how angiography may appear before and after clot retrieval in an eligible stroke treatment.
These are representative educational illustrations, not an identifiable patient's records, not clinical evidence of an expected result, and not a prediction of your outcome. Results and recovery vary by condition, procedure, and patient.
Recovery
Treatment is only one part of recovery.
Recovery is different for every procedure and patient. These stages explain what is usually planned, not how quickly any individual will recover. Your treating team's instructions take priority.
Before discharge
Individual review
The treating team checks the access site, symptoms, medicines, and whether observation or a longer stay is needed.
Early recovery
Activity guidance
Walking, lifting, wound care, and return to work depend on the procedure and your health.
Follow-up
Clinical review
The timing and type of follow-up are chosen for the condition and treatment performed.
Ongoing care
Medicines and risk factors
Some patients need long-term medicines, wound care, rehabilitation, or specialist follow-up.
If symptoms change
Seek advice
Follow the discharge instructions and seek urgent help for the warning signs your treating team explains.

On Practice
"The disease is approached where it lives — through the vessel itself."
Patient journey
From diagnosis to recovery.
Every decision begins with understanding the disease. Imaging guides the diagnosis, treatment is planned around the individual patient, and follow-up continues long after the procedure is complete.
Stage 02
Imaging
Doppler. CT angiography. MR angiography. The disease is seen before it is touched.
Stage 03
Diagnosis
The plan is shared in plain language. Options weighed. Questions answered.
Stage 04
Treatment planning
Every option is put on the table — including doing nothing. Risk, benefit and timing are discussed until the choice is yours.
Stage 05
Procedure
Performed in a hybrid cath lab. Real-time imaging guides every millimetre.
Stage 06
Recovery
Short stay. Same-day or next-day discharge for most procedures.
Stage 07
Follow-up
Imaging review and long-term care to keep what was restored.

Inside the work
A look at how the treatment actually happens.
Support
Common questions.
Understanding vascular and neuro interventional treatments.
Every minute counts. For acute ischemic stroke, 'time is brain.' In selected cases, mechanical thrombectomy can be performed within hours of symptom onset to remove the clot and restore blood flow.
