Interventional Radiology 

The Interventional Radiology (IR) service at London North West Healthcare NHS Trust is led by Professor Martin Malina and delivered by a team of specialist interventional radiologists, interventional nurses, radiographers and administrative staff. Seven IR consultants operate at the Northwick Park site. One consultant also provides IR services at Ealing Hospital and two consultants provide IR services also at Hillingdon Hospital.

As part of The West London Vascular & Interventional Centre, the unit performs a wide range of vascular and non-vascular interventional procedures utilising minimally invasive techniques. We treat many medical and surgical complaints, ranging from complex thoracic and abdominal aneurysms to uterine fibroids. For more information about The West London Vascular & Interventional Centre and it's services please visit - http://westlondonvascular.nhs.uk

Majority of services are provided at the Northwick Park Hospital site where there is a newly built state of the art Hybrid theatre suite and an IR suite with a dedicated recovery area. Interventional radiology procedures are also performed in an IR suite in the Radiology department at Ealing Hospital. 

The West London Vascular Interventional Centre is the regional specialist Interventional Radiology centre and provides out of hours emergency care for Hillingdon Hospital patients as well as specialist support for St Mark’s Hospital.
