Study type
Description of intervention(s) / exposure
minimally invasive stereotactic puncture and thrombolysis therapy (one intervention group): firstly, the target points was defined according to the computer tomography and mostly target points were chosen in the scan with the largest expansion of the haematoma. Puncture situs was measured and marked on head noticing to get out of the way of main blood vessel, then puncture needle of suitable length(Type YL-1) was fixed on the operative electric drill. The puncture needle was perforated into predetermined depth, then the probe core removed, hematoma drawn out gently by syringe (diluted by saline solution if blood thicken) until 1/3 of hematoma were removed, then hematoma was continuiosly liquefied by liquefacient(containing 20000U-40000U urokinase/2-3mL saline solution)for 2-4 days(3-5 times per day) until 90% hematoma drained.

Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A randomized control clinical trial was undertaken. All ICH patients came from in-hospital, diagnosed as ICH according to the ICH criteria of which is drafted by ASA. The clinical trial was in compliance with the WMA Declaration of Helsinki - Ethical Principles for Medical Research Involving Human Subjects, and was performed with the approval of our hospital ethics committee(ID JSCS2005058). Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
we generate the sequence by a randomized number generated by computer

Brief summary
The purpose of this study is to judge the clinical value of minimally invasive stereotactic puncture and thrombolysis therapy (MISPTT) on acute intracerebral hemorrhage(ICH).
A randomized control clinical trial was undertaken by means of compare of Glasgow Coma Scale(GCS) score, postoperative complications(PC) and long-term outcome of 1 year postoperation with conventional craniotomy. We expect to verify whether MISPTT could displayed its superiority in minute trauma, safety, and improving long-term outcome.
