Results
Six types of aortic arch branching were found in this study.
In 792 cases (79.2 %) classical branching pattern of arcus aorta (three branches; Turuncus Brachiocephalicus(TB),
Left Commen Carotid Artery (LCC),
Left Subclavian Artery (LS)) was observed.
The most frequent variation was origination of LCC from TB (arch with 2 branches,
TB with LCC and LS) which was observed in 167 cases (16.7 %)( Fig 1).
Origination of Left Vertebral Artery (LV) directly from the aortic arch (four branches; TB,
LCC,
LV,
LS or TB,
LCC,
LS,
LV) was observed in 22 cases (2,2 %).
16 cases (1.6 %) had aberrant RS (RCC,
LCC,
LS,
RS).
Two cases ( 0.2 %) had right aortic arch.
Also one situs inversus totalis was observed (0.1%).
We found 22 cases with vertebral artery outlet anomalies and 14 cases of them we used Doppler US examination..
Velocity,
volume,
total volume,
resistivity index (RI) and pulsatility index (PI) parameters of every two VA are utilized with Doppler US method in 14 cases.
Doppler US parameters and clinical findings was normal of 14 cases of vertebral artery outlet anomalies (Fig 2-3).
