The CCINR guidelines are under regular review to ensure that they are consistent with current practice. Any changes to the guidelines proposed by the committee must be ratified by each of the parent bodies (ANZSNR, ANZAN, NSA) and the Faculty Council of RANZCR, as per the terms of reference of CCINR.

Changes proposed in 2017 and fully endorsed in 2018 reflect changes in practice since the 2016 guidelines, namely the significant increase in volume of work related to mechanical thrombectomy/endovasular clot retrieval, and the reduction in the number of cases of particulate embolisation for neoplasms (the latter noted on a survey of current ANZ INR practice). 

The 2016 guidelines are available for comparison here.


Conjoint Committee Guidelines for Recognition of Training in Interventional Neuroradiology (INR)*

1.     Introduction

1.1.      Interventional Neuroradiology (INR) uses percutaneous and endovascular procedures to treat patients with diseases of the brain, sensory organs, head and neck, spinal cord, vertebral column and adjacent structures and the peripheral nervous system in adults and children.

1.2.      The Conjoint Committee for Recognition of Training in INR (Conjoint Committee) is an Australian and New Zealand body comprising equal representation from the Australian and New Zealand Society for Neuroradiology (ANZSNR), the Australian and New Zealand Association of Neurologists (ANZAN) and the Neurosurgical Society of Australasia (NSA).

1.3.      The Conjoint Committee has responsibility for the provision of these Guidelines relevant to certification of training in INR, the assessment of applicants from the ANZSNR, ANZAN and NSA seeking certification of relevant training and experience, and the maintenance of the Register of members who have been certified under these Guidelines. The Conjoint Committee is not an accrediting or credentialing body, but rather recognises training and experience.

1.4.      These Guidelines provide a benchmark for the training that is required to safely perform INR. Although percutaneous spinal procedures are usually included in interventional neuroradiology, these procedures will not be dealt with in these Guidelines. In these Guidelines the term INR refers to endovascular interventional neuroradiology only. Endovascular approaches represent the most complex and potentially high-risk aspects of interventional neuroradiology.

2.     Application eligibility requirements

2.1.      The Conjoint Committee recognises training of INR specialists who are, or are about to commence, practising in INR in Australia or New Zealand.

2.2.      The applicant must be admitted to Fellowship of the Royal Australian and New Zealand College of Radiologists, the Royal Australasian College of Surgeons (Neurosurgery) or the Royal Australasian College of Physicians (Neurology).

2.3.      Applicants must have completed an INR training program prior to application and must satisfy the requirements in sections 3 to 5 inclusive.

2.4.      All applicants must submit their application, with the appropriate fee, in accordance with any published instructions of the Conjoint Committee. Incomplete applications will not be considered.

2.5.      All applicants must have a current radiation license or equivalent as required in the jurisdiction in which they practice.

3.     Training Service requirements

3.1.     To be eligible for consideration, INR training must have been completed in one or more training centres, or network of training centres (the Training Service), each with appropriately credentialed INR teams and appropriate neuroscience support services. To ensure appropriate standards of clinical governance and patient safety and quality, the Conjoint Committee recommends that INR services do not operate under solo practitioner arrangements.

3.2.      The applicant must demonstrate that the Training Service has been performing a minimum of 100 neurointerventional procedures per year, including a minimum of 50 aneurysms, and a comprehensive mix of procedures, including the endovascular management of ischaemic stroke, cranial and spinal vascular malformations and arteriovenous fistulas.

3.3.      The applicant must demonstrate that their training position was an integral part of the Training Service. This includes participation in emergency department assessment, preoperative clinic and postoperative clinic follow up, as well as in patient care.

3.4.      The applicant must demonstrate that the Training Service has regular audit and morbidity and mortality meetings, with all members of the INR team actively participating.

4.     Training and Experience requirements

4.1.      The applicant must have undertaken a formal INR training program in one or more appropriate Training Services (see section 3) of not less than 2 years’ duration.  It is recommended that a minimum period of one year is spent in at least one of the Training Services. 

4.2.      The applicant must provide evidence of formal teaching sessions attended as part of the INR training program. The Conjoint Committee would expect the formal teaching program to include as a minimum:

(a)  the anatomy and physiology of the brain, head and neck and spine;

(b)  pathology and clinical management of disorders amenable to neuroendovascular techniques;

(c)  coagulation pathophysiology and the use of anticoagulant, antiplatelet and procoagulant medications in the clinical setting;

(d)  complication assessment, avoidance and management in the neurointerventional setting;

(e)  attitude and ethics in INR; and

(f)   research in INR.

4.3.      The applicant must provide a supervisor-certified logbook of procedural experience. The Conjoint Committee expects the logbook to demonstrate that the INR training program provided the applicant with exposure to and participation in:

(a)  selective intra and extracranial vessel cannulation with microcatheters;

(b)  deployment of detachable coils in intracranial aneurysms;

(c)  embolisation with particulate and non-particulate material of the head, neck, brain and spine;

(d)  extracranial and intracranial balloon angioplasty, remodelling and stenting;

(e)  neurophysiological testing, either through chemical means or temporary occlusion;

(f)   20 cases of vascular reconstruction or angioplasty using balloons or stents for ischaemic disease or vasospasm, including 10 as primary operator;

(g)   10 cases of the use of particulate embolisation material, including 5 as primary operator;

(h)  10 cases of liquid embolisation, including 5 as primary operator

(i)  60 cases of coil embolisation of aneurysm including 20 cases of advanced aneurysm embolisation techniques either with remodelling or stenting, including 30 as primary operator;

(j)   knowledge of the practice of neurophysiological testing (Wada, temporary balloon occlusion, superselective lignocaine or amytal infusion);

(k) 40 cases of endovascular treatment of acute ischaemic stroke

NB. None of items (f) to (k) inclusive may be considered in isolation as satisfactory training in that particular procedure. For example, satisfactory completion of item (h) alone does not mean that a physician is competent to perform liquid agent neuroembolisation. Items (f) to (k) are considered mutually and inclusively necessary for safe practice in INR.

5.     Supervisor confirmation of training and experience

5.1.      The applicant must provide reports on  INR Training and Experience Reports (Reports) from two Supervisors, in such a form as required by the Conjoint Committee.

5.2.      The Supervisors must be appropriately credentialed senior INR specialists (ie on the Conjoint Committee register of INR specialists, or adjudged by the Conjoint Committee to be substantially equivalent) in the Training Service where the INR training program was undertaken and must have had direct personal supervision of the applicant during their INR training program.

5.3.      The Supervisors, in completing the Reports, must confirm that:

(a)   the Training Service satisfies the requirements in section 3 of these Guidelines;

(b)  the applicant satisfies the requirements in section 4 of these Guidelines;

(c)  the applicant competently performs the procedures safely and expeditiously;

(d)  the applicant competently integrates indications for other procedures and therapy into patient management;

(e)  the applicant recognises and manages complications appropriately; and

(f)   the applicant understands risk factors and is able to recognise personal and procedural limits.

6.     Inclusion in the CCINR Register

6.1.      The Register is a list of members who have been certified by the Conjoint Committee as having appropriate training and experience in INR, as indicated by these guidelines.
