Early Lumbar Drainage for Intraventricular Hemorrhage (LD-IVH)

1. September 2026 aktualisiert von: Second Affiliated Hospital of Nanchang University

Effectiveness and Safety of Early Lumbar Drainage in the Treatment of Ventricular Hemorrhage: the LD-IVH Randomized Controlled Trial

This is a multicenter, prospective, randomized, open-label, blinded-endpoint (PROBE) trial in Chinese patients with intraventricular hemorrhage (IVH), comparing early lumbar drainage added to standard care with standard care alone. The primary objective is to evaluate whether, in patients treated with external ventricular drainage (EVD) and intrathecal urokinase, the addition of early lumbar drainage improves functional outcomes at 180 days, as measured by the modified Rankin Scale (mRS), and reduces complications.

Detaillierte Beschreibung

Intraventricular hemorrhage (IVH) is a life-threatening complication of acute stroke, associated with high rates of mortality and severe disability, fewer than 20% of survivors achieve favorable functional outcomes. Despite the widespread use of external ventricular drainage (EVD) and intraventricular thrombolysis, the role of early lumbar drainage in improving outcomes remains controversial, with limited high-level evidence from randomized controlled trials.

The LD-IVH study will use a 1:1 stratified block randomization design, with stratification by intraparenchymal hematoma and hospital. Eligible patients will be randomized to receive either (1) control group treatment: standard EVD plus daily intrathecal urokinase (30,000 IU) for 3 consecutive days, with a maximum treatment duration of 5 days; or (2) intervention group treatment: the same EVD and intrathecal urokinase regimen as the control group, with early lumbar drainage additionally initiated within 72 hours of onset. CSF was drained at a rate of ≤8 mL/h, with a daily maximum volume of 200 mL, to keep intracranial pressure stable.

The primary endpoint will be the proportion of patients with a favorable functional outcome (modified Rankin Scale [mRS] score 0-3) at 180 days. A total of 392 patients will be enrolled, and an interim efficacy analysis is planned after 50% of participants complete the 180-day follow-up.

Teilnehmergruppe / Arm
Intervention / Behandlung
Aktiver Komparator: Control Group (EVD + Intrathecal Urokinase)
Patients received external ventricular drainage (EVD) combined with intrathecal urokinase injection. Urokinase was administered as a single daily dose of 30,000 IU for 3 consecutive days. A follow-up cranial CT was then performed to assess ventricular obstruction and hematoma clearance, which guided the decision on whether to continue thrombolysis. The maximum total duration of urokinase treatment did not exceed 5 days. Thrombolysis was discontinued when CT demonstrated clearance of the third/fourth ventricular cast, relief of mass effect, or a hematoma clearance rate of ≥80%.

Experimental: Intervention Group (Control Treatment + Lumbar Drainage)
In addition to the same EVD and intrathecal urokinase regimen as the control group, early lumbar drainage was initiated within 72 hours of onset. The CSF drainage rate was maintained below 8 mL/h, and the daily total drainage volume did not exceed 200 mL to maintain stable intracranial pressure.
Early lumbar cistern drainage was initiated within 72 hours of onset. The CSF drainage rate was maintained below 8 mL/h, and the daily total drainage volume did not exceed 200 mL to maintain stable intracranial pressure.
