Notes:
a
Miscellaneous diagnostic tools are i) findings during surgery (PE and arterial thrombosis), ii) biochemical markers and/or electrocardiogram findings in MI, iii) ophthalmoscopic examination in retinal occlusion.
b
Method of examination was unknown in one patient with DVT in the extremities and abdomen.
c
Type of brain scan was unknown in one patient with AIS.
d
Two newborns were included based on clinical signs of a threatened limb. Imaging or surgery was not performed.
Abbreviations: AIS, arterial ischemic stroke; CT, computed tomography; CSVT, cerebral sinovenous thrombosis; DVT, deep venous thrombosis; MI, myocardial infarction; MR, magnetic resonance; PE, pulmonary embolism.
