To evaluate the current status of interventional radiology in Canada.
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.
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.
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.
评估加拿大介入放射学的现状。
向加拿大28位介入放射科医生（定义为进行任何类型介入操作的医生，包括活检，但不包括介入神经放射学）发放问卷，这些医生在除爱德华王子岛外所有省份的主要中心的三级医院和社区医院执业。
28份调查问卷中有22份（79%）完成并返回，提供了有关86位介入放射科医生的数据。介入放射科医生在其机构中几乎进行了以下所有操作：下腔静脉滤器置入、静脉血管成形术、透析瘘管血管成形术、诊断性和治疗性肺及支气管动脉操作、下肢和肾动脉的诊断性和治疗性操作、经皮脓肿和胆道引流操作、经皮肾造瘘术以及子宫肌瘤栓塞术。在大多数机构中，由介入放射科医生和非放射科医生共同进行的另一组操作包括：所有类型的中心静脉导管置入、胸腔引流和胃造瘘管置入。在许多机构中无人进行的操作包括：透析移植血管溶栓、精索静脉曲张栓塞、经颈静脉肝内门体分流术、胃肠道姑息性支架置入、输卵管再通以及肝脏和前列腺肿瘤治疗。最常限制受访者提供全面介入服务能力的因素是介入放射学设备预算和介入放射学房间的可用性；50%的受访者表示可用护士、技术人员和介入放射科医生的数量也是一个重要的限制因素。
加拿大的介入放射科医生在许多最常见的操作中仍发挥着主要作用。然而，许多机构中资源和人员的有限可用性可能会阻碍介入放射科医生开展新操作的能力。
