Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will consist of endovascular delivery one or more Pipeline-Shield devices to treat patients with this particular subset of difficult aneurysms using aspirin as the sole antiplatelet agent. This will be done by experienced (CCINR-certified) interventional neuroradiologists. The procedure will be a once-only intervention, with follow up on imaging studies using a combination of MRI and angiography. Clinical follow up will also be obtained. The follow up period for this trial will be 6 months.

Aspirin will be administered as a 500mg intravenous dose during the procedure and continued orally or via nasogastric administration post procedurally, depending on the patients' level of consciousness at a dose of 100-300mg daily in single or divided dose. Compliance will be monitored during the inpatient period by medication charts, and during the outpatient phase by regular follow up phone calls with patients/carers and at gazetted clinical face-to-face meetings.

Outcomes
Primary outcome [1] 307700 0
Stent patency (short term)

This will be assessed between days 5-15 with digital subtraction angiography.
Timepoint [1] 307700 0
5-15 days post treatment.

This timepoint varies from patient to patient and will only be assessed at a single timepoint within these days unless further angiography is required on clinical grounds.
Secondary outcome [1] 352570 0
Aneurysm occlusion (short term)
Timepoint [1] 352570 0
Day 5-15. Patients with this condition will require at least one digital subtraction angiogram during their admission in the 5-15 day window. This varies from patient to patient depending on their clinical need. The trial merely stipulates that at least one DSA should be done in this window.
Secondary outcome [2] 352571 0
Aneurysm occlusion (long term)
Day 5-15 DSA (as per above)
MRI at day 60 post treatment
DSA at 6 months
Timepoint [2] 352571 0
180 days post treatment
Secondary outcome [3] 352572 0
Stent patency (long term)
MRI at day 60 post treatment
DSA at 6 months
Timepoint [3] 352572 0
60 and 180 days post treatment
Secondary outcome [4] 352574 0
New cerebral ischaemia
MRI within 72 hours of treatment
MRI at day 60 post treatment
Timepoint [4] 352574 0
Within 72 hours of treatment and at 60 days post treatment
Secondary outcome [5] 352575 0
Haemorrhagic complications

These will be assessed based on clinical evaluation since they are usually symptomatic. Occasionally, silent haemorrhagic changes can be seen on MRI (therefore possibly visible on MRI scans as above).

Examples would include:
Intracerebral haemorrhage
Aneurysm rebleeding
Gastrointestinal bleeding
Excessive bruising
Menorrhagia
Epistaxis
Timepoint [5] 352575 0
Any haemorrhagic complication up to 180 days post treatment.

Eligibility
Key inclusion criteria
• 18 years or older
• Ruptured intradural aneurysm with morphology not amenable to conventional open or
endovascular repair
• Ruptured intracranial aneurysm unsuitable for open repair, requiring stent support for
endovascular therapy (EVT), but with contraindication to dual antiplatelet therapy, for
example:
o Requirement for immediate ventricular drainage
o Requirement for urgent craniotomy and haematoma evacuation
o Requirement for tracheostomy or other major surgical procedure
o Allergy to clopidogrel, prasugrel
• Criteria above to be evaluated by consultation between the duty open and endovascular
consultants at the participating centre.
• Verbal and written consent from patient and/or next of kin
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
• All ruptured aneurysms where conventional open neurosurgical and endovascular repair
techniques are deemed feasible by the open and endovascular consultant on duty
• Inability to obtain consent from patient or guardian/next of kin
• Contraindication or allergy to aspirin
Age <18 years
