Table 2 Ishikawa criteria (1988)

From: French recommendations for the management of Takayasu’s arteritis

Major criteria  
1. Stenosis or occlusion of the middle portion of the left subclavian artery on the arteriography
2. Stenosis or occlusion of the middle portion of the right subclavian artery on the arteriography
3. Characteristic symptoms lasting at least one month: claudication, absence of a pulse or blood pressure asymmetry, fever, cervicalgia, amaurosis, visual disorders, syncope, dyspnea, palpitations.
Minor criteria
1. SR > 20 mm/h  
2. Sensitivity of carotid arteries to palpation  
3. High blood pressure: humeral pressure—140/90 mmHg, or popliteal pressure—160/90 mmHg  
4. Aortic insufficiency or annuloaortic ectasia  
5. Pulmonary arterial impairment  
6. Stenosis or occlusion of the middle portion of the left carotid artery on the arteriography  
7. Stenosis or occlusion of the distal third of the brachiocephalic artery trunk on the arteriography  
8. Impairment of the descending thoracic aorta on the arteriography  
9. Impairment of the abdominal aorta on the arteriography  
10. Coronary heart injury before the age of 30, in the absence of dyslipidemia or diabetes  
A diagnosis of Takayasu’s arteritis is highly likely if: ≥ 2 major criteria or 1 major criterion and ≥ 2 minor criteria or ≥ 4 minor criteria
