The study reveals that a delay of one hour before surgery results in a 9-month loss of full quality of life for the patient and $ 14,000 for the company. The cost for two hours of delay: two years of full quality of life and an account of $ 26,000.
"It is often said that one-minute blockage of an artery in the brain kills 1.9 million neurons per minute, so we may think that an hour of ischemia, blockage of an artery, kills several million neurons, which results in physical and cognitive impairments, "says Dr. Alexandre Y. Poppe, a neurologist at CHUM.
In Canada, it takes an average of two hours to transport a patient to a health center, evaluate it and administer a medical imaging test.
Thrombectomy is then performed in specialized centers if necessary. The procedure removes the clot that blocks the artery and the blood can then circulate again. For cases treated in specialized centers, there is a 50% decrease in mortality.
What is a stroke?
Ischemic stroke (CVA) is a consequence of the lack of oxygen in one part of the brain. It can be the result of thrombosis or embolism (migration of a clot or debris of fat deposits) of the brain. In both cases, a part of the brain is less irrigated. There will therefore be a more or less important neurological deficit (paralysis) corresponding to the brain territory reached.
Is it possible to do even better?
"In Quebec, there are only four centers offering this special treatment, two in Montreal, one in Quebec and one in Sherbrooke, so there are all the problems of being able to quickly bring patients into the ambulance in the right place."
In more remote areas, videoconferencing is an interesting option.
"We installed, among other things, the tele-shots, where even if we do not have access to a large center or a neurologist or all the specialized equipment, we can, at a distance, with a neurologist, make an initial diagnosis, a first exam and decide what to do, among other things to give the right drug, the right intervention quickly, "says Andréane Tardif of the Heart and Stroke Foundation.
Today, 80% of Canadians survive the stroke, but more than half still have a long-term disability.
