Interventional radiology is used to diagnose or treat pathology with the most minimally invasive technique possible. Images are used guide instruments through the body to areas for treatment. This minimizes the physical trauma to the patient and can reduce infection rates and recovery time as well as shorten hospital stays.
There are three interventional suites at London Bridge Hospital including one of the UK’s first Hybrid Laboratories for complex procedures. State of the art technology which includes many dose saving features allows imaging of any part of the body and facilitates complex cardiac, liver related (HPB), orthopaedic and many other procedures. Live image display with matching 3D reconstruction can facilitate guidance during complex interventions.
Common IR procedures are:
- Angiography: imaging the blood vessels to look for abnormalities.
- Balloon angioplasty/stent: opening of narrow or blocked blood vessels using a balloon; may include placement of metallic stents as well.
- Embolisation: blocking abnormal blood vessels (e.g., for the purpose of stopping bleeding) including uterine artery embolisation for percutaneous treatment of uterine fibroids.
- Chemo-embolisation: delivering cancer treatment directly to a tumour through its blood supply, then using clot-inducing substances to block the artery, ensuring that the delivered chemotherapy is not "washed out" by continued blood flow.
- EVAR – Endovascular aortic repair
- TAVI – trans catheter aortic valve implantation
- Line insertion: Vascular access and management of specialized kinds of intravenous devices (e.g. PICC lines, Hickman lines and subcutaneous ports.
- Vertebroplasty: injection of bone cement inside fractured vertebrae
- Nephrostomy tube insertion: Placing a catheter directly into the kidney to drain urine in situations where normal flow of urine is obstructed
- Dialysis access and related intervention: Placement of tunneled haemodialysis catheters, peritoneal dialysis catheters, and revision/thrombolysis of poorly functioning surgically placed AV fistulas and grafts.
