Image Guided Interventional Surgery (IGIS) 'Hub' at GRH
Image Guided Interventional Surgery (IGIS) means procedures where the surgeon uses instruments with live images to guide the procedure.
The new IGIS Hub at Gloucestershire Royal Hospital will establish a 24/7 hub for image guided interventional surgery, comprising interventional radiology, vascular surgery and interventional cardiology.
We are bringing together the staff and resources we have and establishing a 24/7 hub at GRH, while a satellite IGIS service will operate from CGH, with an interventional surgery suite supporting some elective work alongside urology and cancer image guided surgery.
The IGIS Hub
The IGIS construction programme began in late 2022 and is expected to take approximately 18 months until fully complete. This will include:
- 3x cardiac catheter laboratories
- 2x interventional radiology suites
- 1x Hybrid imaging theatre



Why image-guided surgery?
One of the benefits of image guided surgery is that when you need an operation the surgeon does not need to make a large cut and instead can perform your surgery via a small ‘keyhole’, which means you can heal and recover more quickly. This avoids the need for more invasive, open surgery. It reduces the risk to the patient, the amount of time the person needs to stay in hospital and their recovery time.
Planned treatments:
- Treating furred-up arteries in the leg
- PCI (Percutaneous Coronary Intervention): unblocking arteries in the heart
- Cancer diagnosis and treatment
- Electrophysiology: treating disorders of the heart’s electrical systems.
Emergency treatments:
- Treating bleeding blood vessels in the gut
- Primary PCI (unblocking the heart’s arteries in an emergency).
Interventional Radiology means using real-time images of the inside of your body, captured by X-ray, MRI, ultrasound scans and CT scans to diagnose or treat problems with blood vessels.
Interventional Cardiology (heart medicine and surgery), vascular surgery (diagnosis and management of arteries) and interventional radiology use similar equipment, similarly trained support staff and have similar processes for caring for you following a procedure. These services also regularly need specialist input from each other and in many cases, they are treating the same group of patients.
Building works disruption
From 23 – 25 May and 30 May – 1 June
Disruption due to building work at GRH will affect vehicle access to the Main Atrium entrance over these dates
Cranage works will be ongoing from 23 – 25 May, and again 30 May – 1 June to install critical infrastructure for the IGIS Hub.
This means that access to the ED and main Atrium will be disrupted.
Parking outside the Atrium will NOT be available at this time. This may cause congestion around the site and you may wish to allow extra time to get to your appointments.
This will require the closure of some internal corridors, for which signage will be in place.
Alternative drop off point will be through the therapies entrance (see below).
From 11 May - 18 May 2023
Cranage works will be ongoing from 11-18 May 2023 to install critical infrastructure for the IGIS Hub.
This means that access to the ED and main Atrium will be disrupted.
Parking outside the Atrium will NOT be available at this time. This may cause congestion around the site and you may wish to allow extra time to get to your appointments.
This will require the closure of some internal corridors, for which signage will be in place.
Alternative drop off point will be through the therapies entrance.
From 25 April - 27 April
Cranage works will be ongoing from 25 - 27 April to install critical infrastructure for the IGIS Hub.
This means that access to the ED and main Atrium will be disrupted.
Parking outside the Atrium will NOT be available at this time. This may cause congestion around the site and you may wish to allow extra time to get to your appointments.
There will be a crane on site on Wednesday 26 April. This will require the closure of some internal corridors, for which signage will be in place.
Alternative drop off point will be through the therapies entrance.
From 13 March - 17 April
Cranage works will be ongoing from 13 March to 77 April to install critical infrastructure for the IGIS Hub. This means that access to the ED and main Atrium will be disrupted. Parking outside the Atrium will NOT be available at this time. This may cause congestion around the site and you may wish to allow extra time to get to your appointments.
Internal corridor closures (ground and first floor of the atrium) 14 March - 6 April
Three corridors will be closed while the crane disruption continues as cranes will be lifting over the building. This affects the corridor on the ground floor with the large timelapse photograph and the first-floor corridor between AMU and first-floor Outpatients, and the corridor from the Atrium (by Costa) to Radiology 1. The corridors will be periodically open and closed between 14 - 27 March, and then closed every weekday between 28 March - 6 April. This applies from 8am - 6pm on weekdays only.
Atrium users (including Outpatient and Paediatric appointments)
- For vehicle access to the Atrium (drop-off), this means accessing the atrium via other routes; for example, the Therapies Entrance including disabled parking (access via Beacon House entrance). Disabled car parking is available as marked on the map.
- For pedestrian access, this means following the green path indicated on the map
- Patient transport ambulances dropping/picking up patients for outpatient appointments will drop them at the Therapies entrance
Emergency Department (ED) users
- Ambulances: normal route – unaffected by these works
- Pedestrians: follow signs and see the map on this page
From 20 February - 1 March 2023
To install critical infrastructure for the IGIS Hub, we’re bringing in a large crane that will be lifted over the front of the Atrium and placed on the roads in front of the entrance. This means that access to the ED and main Atrium will be disrupted.
Parking outside the Atrium will NOT be available at this time. This may cause congestion around the site and you may wish to allow extra time to get to your appointments.
Internal corridor closures (ground and first floor of the atrium) 21- 28 February
Three corridors will be closed while the crane disruption continues as cranes will be lifting over the building. This affects the corridor on the ground floor with the large timelapse photograph and the first-floor corridor between AMU and first-floor Outpatients, and the corridor from the Atrium (by Costa) to Radiology 1. Signage will be in place. Please ask one of our volunteer team for help if you are unable to find your way. This applies from 8am - 6pm on weekdays only.

From 6 - 15 February 2023
To install critical infrastructure for the IGIS Hub, we’re bringing in a large crane that will be lifted over the front of the Atrium and placed on the roads in front of the entrance. This means that access to the ED and main Atrium will be disrupted. Parking outside the Atrium will not be available.
This may cause congestion around the site and you may wish to allow extra time to get to your appointments.
Internal corridor closures (ground and first floor of the atrium)
Two corridors will be closed while the crane disruption continues as cranes will be lifting over the building. This affects the corridor on the ground floor with the large timelapse photograph and the first-floor corridor between AMU and first-floor Outpatients. Signage will be in place. Please ask one of our volunteer team for help if you are unable to find your way. This applies from 8am - 6pm on weekdays only.
