What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether robot-assisted cerebral angiography is as safe and effective as the standard manual procedure. The robot allows doctors to operate from a shielded room, potentially reducing their radiation exposure. About 156 adults with suspected brain blood vessel issues will be randomly assigned to either robot-assisted or manual angiography. The study measures success rates, complications, and radiation doses for both patients and doctors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Robot-assisted angiographic system
What this could lead to
If successful, robot-assisted angiography could become a standard safer alternative, reducing radiation exposure for medical staff while maintaining patient safety.
What could go wrong
This is a relatively small, early-stage trial. Robot technology may have technical issues, and results may not apply to all hospitals or patient types.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Aged 18 to 80 years, regardless of gender; * Stable vital signs, eligible for routine cerebral digital subtraction angiography (DSA); * Suspected intracranial vascular lesions (stenosis, aneurysm, malformation, etc.) by computed tomography angiography (CTA)/magnetic resonance angiography (MRA) requiring further confirmation, or need to clarify the blood supply of intracranial space-occupying lesions/qualification of tumors; * Positive Allen's test; * Ultrasound shows radial artery diameter \>2.0 mm, or \<2.0 mm but still eligible for transradial angiography as evaluated by senior physicians. Exclusion Criteria: * Patients with contrast medium allergy; * Patients with acute hemorrhagic/ischemic cerebrovascular disease requiring emergency cerebral DSA, and patients with unstable acute stroke; * Patients with severe vascular malformation/stenosis/occlusion, severe hepatic and renal insufficiency, severe hypertension/hypotension, severe infection, coagulation dysfunction, severe cardio-cerebro-pulmonary diseases, congestive heart failure; * Pregnant/lactating women and women planning to become pregnant within 1 year; * Patients clinically ineligible for cerebral DSA; * Patients with fear of interventional robots and refusal of robot-assisted angiography.
