Israeli Premier Ariel Sharon was ailing from an undiagnosed disease in his brain blood vessels when he was administered anti-coagulants, which are known to increase the risk of strokes and brain haemorrhage.
Had doctors treating the leader detected the disease earlier, they would almost certainly not have prescribed the anti-coagulants or blood thinners, which are known to increase the risk of strokes, according to a media report here.
Haaretz newspaper quoted a doctor treating Sharon as saying that the disease, Cerebral Amyloid Angiopathy, was diagnosed at the Hadassah University Hospital during Sharon's current hospitalisation.
The disease could have greatly increased the risk of a brain haemorrhage following the administration of the anti-coagulants that Sharon received after his first stroke on December 19, Haaretz said.
According to the medical testimony, had CAA been detected when Sharon was admitted to Hadassah after his first stroke, the doctors would probably not have given the medication, which they believe led to the subsequent severe haemorrhaging of the prime minister, it said.
However, Ron Krumer, Hadassah's external affairs director said, "We are busy treating the prime minister and fighting to save his life. We are not dealing with anything else."
The doctor who provided the testimony defined the administering of anti-coagulants after the first stroke as a 'screw up', the daily said.
CAA could be a genetic disorder while sometimes, its origin is unknown. The disease is diagnosed by means of interpreting CT and MRI scans or by performing a biopsy on a small sample of the brain, it said.
