Obstruction of an artery

Cerebral ischaemia - Obstruction of an artery Factor

The factor, which applies only to cerebral ischaemia, requires the obstruction to be due to pressure from an extra-arterial source and to be located in one of the following arteries:

• vertebral
• common carotid
• internal carotid
• cerebral

Pressure from an extra-arterial source may arise from osteophytes (bony spurs), tumours or foreign bodies.  Seek medical advice if the evidence is unclear.

Investigative Documents

Preliminary questions [18165]

20879 there is some evidence that obstruction of an artery may be a factor in the development of the condition under consideration.

18181 the veteran has had obstruction of a vertebral artery, common carotid artery, internal carotid artery or a cerebral artery, due to pressure from an extra-arterial source, at some time.

18183 the veteran had obstruction of a vertebral artery, common carotid artery, internal carotid artery or a cerebral artery, due to pressure from an extra-arterial source, at the time of the clinical onset of the condition under consideration.

37226 the obstruction of a vertebral artery, common carotid artery, internal carotid artery or a cerebral artery, due to pressure from an extra-arterial source, at the time of the clinical onset of the condition under consideration, was a consequence of an illness or injury which is identifiable.

18184  the veteran has established the causal connection between obstruction of an artery and VEA service for the clinical onset of cerebrovascular accident.

18185   the veteran has established the causal connection between obstruction of an artery and operational service for the clinical onset of cerebrovascular accident.

18186   the veteran has established the causal connection between obstruction of an artery and eligible service for the clinical onset of cerebrovascular accident.

Clinical onset and operational service [18185]

3471     the identified illness or injury, which caused the obstruction of a vertebral artery, common carotid artery, internal carotid artery or a cerebral artery, due to pressure from an extra-arterial source, at the time of the clinical onset of the condition under consideration, is causally related to operational service.

Clinical onset and eligible service [18186]

3473     the identified illness or injury, which caused the obstruction of a vertebral artery, common carotid artery, internal carotid artery or a cerebral artery, due to pressure from an extra-arterial source, at the time of the clinical onset of the condition under consideration, is causally related to eligible service.
