The current status of interventional radiology in Canada: results of a survey by the Canadian Interventional Radiology Association.
OBJECTIVE
To evaluate the current status of interventional radiology in Canada.


METHODS
A questionnaire was sent to 28 Canadian interventional radiologists (defined as a physician who performs any type of interventional procedure, including biopsies, but excluding interventional neuroradiology) practising in both tertiary and community hospitals in the major centres in all provinces except Prince Edward Island.


RESULTS
Twenty-two (79%) of 28 surveys were completed and returned, providing data about 86 interventional radiologists (IRs). IRs were performing almost all of the following procedures at their institutions: inferior vena cava filter placement, venous angioplasty, dialysis fistula angioplasty, diagnostic and therapeutic pulmonary and bronchial artery procedures, diagnostic and therapeutic procedures of the lower extremity and renal arteries, percutaneous abscess and biliary drainage procedures, percutaneous nephrostomy, and fibroid embolization. A second group of procedures, performed by both IRs and non-radiologists in most institutions, included: all types of central venous catheter placements, pleural drainage, and gastrostomy tube placement. Procedures not being performed by anyone in a number of institutions included: dialysis graft thrombolysis, varicocele embolization, transjugular intrahepatic portosystemic shunts, palliative stenting of the gastrointestinal tract, fallopian tube recannalization, and liver and prostate tumour treatments. The factors most often limiting the respondents' ability to provide a comprehensive interventional service were the interventional radiology inventory budget and the availability of interventional radiology rooms; 50% of respondents indicated the number of available nurses, technologists and IRs was also an important limiting factor.


CONCLUSIONS
IRs in Canada still play a major role in many of the most commonly performed procedures. However, limited availability of resources and personnel in many institutions may be hampering the ability of IRs to develop new procedures.
