Title: Desmopressin for Reversal of Antiplatelet Drugs in Stroke Due to Haemorrhage (DASH)
Brief Summary: Haemorrhagic stroke, an emergency caused by bleeding in the brain, often leads to death or long-term disability. A quarter of these patients are taking blood-thinning drugs (antiplatelet drugs, such as aspirin) because they are at risk of a heart attack or ischaemic stroke. Patients taking these drugs are more likely to die or be disabled if they have a haemorrhagic stroke. At present, there is no effective treatment for reversing their effects. Desmopressin is a drug which may reverse the effects of antiplatelet drugs and stop bleeding. The investigators would like to run a large randomised trial to see if Desmopressin can reduce the number of people who die or are disabled after haemorrhagic stroke.


Options:
A: Inclusion Criteria:

* Patients presenting with an acute ICH
* Contrast extravasation within the haemorrhage, "spot sign", evaluated from the CTA according to three criteria, all of which must be present:

  1. Serpiginous or spot-like appearance within the margin of a parenchymal haematoma without connection to an outside vessel;
  2. The density (in Hounsfield units) should be greater than that of the background haematoma (site investigators are not required to document the density); and
  3. No hyperdensity at the corresponding location on non-contrast CT.
* Age ≥18 years
* Treatment can commence within 1 hour of initial CT and within 4.5 hours of symptom onset (or in patients with unknown time of symptom onset, the time patient was last known to be well)
* Informed consent has been received in accordance to local ethics committee requirements

Exclusion Criteria:

* Glasgow coma scale (GCS) total score of \<8
* Brainstem ICH
* ICH volume \>70 ml as measured by the ABC/2 method
* ICH known or suspected by study investigator to be secondary to trauma, aneurysm, vascular malformation, haemorrhagic transformation of ischaemic stroke, cerebral venous thrombosis, thrombolytic therapy, tumor, or infection
* Contrast already administered within 24 hours prior to initial CT or contraindication to imaging with CT contrast agents (e.g. known or suspected iodine allergy or significant renal failure)
* Any history or current evidence suggestive of venous or arterial thrombotic events within the previous 12 months, including clinical, ECG, laboratory, or imaging findings. Clinically silent chance findings of old ischemia are not considered exclusion.
* Hereditary or acquired haemorrhagic diathesis or coagulation factor deficiency.

* Baseline ICH volume of \> 90 cc
* Planned surgical evacuation of ICH within 24 hours of symptom onset (placement of intraventricular catheter is not a contraindication to study enrollment.)
* Evidence of acute or subacute ischemic stroke on baseline qualifying CT scan
* Clinical history of thromboembolism or ischemic vascular disease, including myocardial infarction, coronary artery bypass surgery, cardiac angina, transient ischemic attack, ischemic stroke, peripheral artery disease (vascular claudication), cerebral bypass surgery, carotid endarterectomy, deep venous thrombosis, pulmonary embolism, or coronary or cerebrovascular angioplasty or stenting. (Clinically silent evidence of old ischemia on EKG (Q waves) or CT scan (silent old infarct) will not be considered reasons for exclusion.)
