Summary

The purpose of this trial is to determine the safety of using a combination of minimally invasive surgery and clot lysis with rt-PA to remove intracerebral hemorrhage (ICH). The procedure is to use image-based surgery (MRI or CT) to provide catheter access to ICH for the intervention, which is a one-time clot aspiration followed by instillation of rt-PA over 72 hours. We propose to test if this intervention facilitates more rapid and complete recovery of function and decreased mortality from this condition compared to conventional medical management without subjecting the patient to craniotomy. The specific objective of this trial is to test the safety of this intervention and assess its ability to remove blood clot from brain tissue.

Clinical Details

Secondary outcome:

Rate of clot size reduction at Days 4-5 determined by CT scans

90 & 180 day GOS, Rankin, Stroke Impact Scale

Eligibility

Minimum age: 18 Years. Maximum age: 80 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Age 18-80

- GCS < 14 or a NIHSS > 6

- Spontaneous supratentorial ICH > 25cc

- Symptoms less than 12 hours prior to diagnostic CT scan (an unknown time of symptom

onset is exclusionary)

- First dose can be given within 36 hours of symptom onset (plus a 2-hour feasibility

window with approval from the coordinating center, reserved for only those situations where the patient is eligible, consented, stable but personnel scheduling prohibits giving the first dose within the 36-hour window)

- Six-hour clot size equal to the most previous clot size + 5 cc (as determined by an

additional CT scan at least 6 hours after the initial stability scan (A*B*C)/2 method)

- SBP < 200 mmHg sustained for 6 hours

- Historical Rankin score of 0 or 1

- Negative pregnancy test

Exclusion Criteria:

- Infratentorial hemorrhage (any involvement of the midbrain or lower brainstem as

demonstrated by radiograph or complete third nerve palsy)

- Patients with platelet count < 100,000, INR > 1. 7, PT > 15s, or an elevated APTT

(reversal of coumadin is permitted but the patient must not require coumadin during the acute hospitalization), Irreversible coagulopathy either due to medical condition or prior to randomization

- Clotting disorders

- Any concurrent serious illness that would interfere with the safety assessments

including hepatic, renal, gastroenterologic, respiratory, cardiovascular, endocrinologic, immunologic, and hematologic disease

- Patients with a mechanical valve

- Patients with unstable mass or evolving intracranial compartment syndrome

- Ruptured aneurysm, AVM, vascular anomaly

- Greater than 80 years (higher incidence of amyloid)

- Under 18 years of ag e (high incidence of occult vascular malformation)

- Pregnant (positive pregnancy test) or lactating females (likelihood of altered

coagulation function associated with the high estrogen/progesterone state)

- Irreversibly impaired brainstem function (bilateral fixed, dilated pupils and extensor

motor posturing), GCS less than or equal to 4

- Historical Rankin score greater than or equal to 2

- Intraventricular hemorrhage requiring external ventricular drainage

- Internal bleeding, involving retroperitoneal sites, or the gastrointestinal,

genitourinary, or respiratory tracts

- Superficial or surface bleeding, observed mainly at vascular puncture and access sites

(e. g., venous cutdowns, arterial punctures) or site of recent surgical intervention

- Known risk for embolization, including history of left heart thrombus, mitral stenosis

with atrial fibrillation, acute pericarditis, and subacute bacterial endocarditis

- In the investigator's opinion, the patient is unstable and would benefit from a

specific intervention rather than supportive care plus or minus MIS+rtPA

- Prior enrollment in the study

- Any other condition that the investigator believes would pose a significant hazard to

the subject if the investigational therapy were initiated

- Participation in another simultaneous trial of ICH treatment.
