About this study

Official title: Chinese Registry of Assisted Embolization for Unruptured Wide Necked Intracranial Aneurysm Using LVIS Stent

This study aims to investigating the efficacy and safety of low profile visualized intraluminal support (LVIS) stents for the treatment of ruptured intracranial saccular aneurysms. The follow-up duration is 1 year.

Read the detailed description

This study is a prospective multi-centre observational single-arm clinical trial, aiming to investigating the efficacy and safety of low profile visualized intraluminal support (LVIS) stents combined with coils for the treatment of ruptured intracranial saccular aneurysms. As the protocol, clinical follow-up at 30 days (±7 days) after procedure, DSA or MRA follow-up at 6 months (±30 days) after procedure, and clinical follow-up at 1 year (±30 days) after procedure was conducted for each patient. The primary end-points include major adverse events (cerebral infarct and death) in 30 days post-procedure, complete occlusion rate at 6 months (180±30d) follow-up, and modified Rankin Score (mRS) at 1 year follow-up. The secondary end-points were immediate technical success (successful device placement) rate, immediate complete occlusion rate, recurrence rate at 6 months (180±30d) follow-up and in-stent stenosis or obliteration rate at 6 months (180±30d) follow-up. Duration of this study is 2 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Major adverse events (cerebral infarct, death) in 30 days post-procedure

    Major adverse events (cerebral infarct, death) in 30 days post the procedure is defined as post-procedural cerebral infarct or death caused by any reasons

    Measured: During 30 days post-procedure

  2. Complete occlusion rate at 6 months (180±30d) follow-up

    Complete occlusion at 6 months follow-up is defined as 100% occlusion of aneurysmal sac proved by DSA at 6 months follow-up

    Measured: At 6 months (180±30d) follow-up

  3. Modified Rankin Score at 1 year follow-up

    The scale runs from 0-6, running from perfect health without symptoms to death.

    0 - No symptoms.

    1. - No significant disability. Able to carry out all usual activities, despite some symptoms.
    2. - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.
    3. - Moderate disability. Requires some help, but able to walk unassisted.
    4. - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.
    5. - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.

    Measured: At 1 year follow-up

Secondary outcomes (4)

  1. Immediate technical success rate (successful device placement)

    Immediate technical successful is defined as good apposition of stents, effective coverage of aneurysmal neck proved by post-procedural imaging examination

    Measured: Within 24 hours postoperatively

  2. Immediate complete occlusion rate

    Immediate Raymond scale is defined as immediate angiographic result according to the simplified Raymond scale, classⅠ: complete occlusion; class Ⅱ: neck remnant; class Ⅲ: incomplete occlusion.

    Measured: Within 24 hours postoperatively

  3. Recurrence rate at 6 months (180±30d) follow-up

    Recurrence rate was defined as increased contrast filling into the aneurysmal sac compared with immediate angiographic result.

    Measured: At 6 months (180±30d) follow-up

  4. In-stent stenosis or obliteration rate at 6 months (180±30d) follow-up

    In-stent stenosis at 6 months follow-up is defined as stenosis more than 50% proved by DSA at 6 months follow-up. In-stent occlusion or thrombosis at 6 months follow-up is defined as complete occlusion of the stent proved by DSA at 6 months follow-up.

    Measured: At 6 months (180±30d) follow-up
