located behind and to the middle. Thymus is located in front of
the left brachiocephalic vein.
The arch of aorta,
truncus brachiocephalicus, a. carotis
communis sinistra, a. subclabia and n. vagus sinister are
located behind vena brachiocephalica sinistra.
SUPERIOR VENA CAVA
V. cava superior goes downwards from the place of formation.
It is located behind the right edge of sternum, from the level of
the 1st rib to the level of the 3rd rib. On the level of the 2nd
intercostal space it goes in pericardial cavity adjoining v. azygos
before. The ascending part of aorta is located to the left from the
vein. It is covered by mediastinal pleura outwards. There is
n. phrenicus dexter followed by a. and vv. pericardiacophrenicae
between the vein and pleura. N. vagus dexter goes behind v. cava
superior.
The inferior part of vein is located in the cavity of pericardium,
in front of root of the right lung. There are anterior mediastinal
lymph nodes along the vein.
AORTA
The ascending part of aorta (pars ascendens aortae) is
located in pericardial cavity. There
is truncus pulmonalis in
front. There is auricula dextra of pericardium on the right and
in front. A. pulmonalis dextra is located on the right.
The ascending part of aorta (pars ascendens aortae) gives
off aa. coronariae dextra et sinistra which originate from
sinuses of Valsalva.
The arch of aorta goes throughout the length from the 1st
to the 2nd cartilages to the left semicircle of the 4th thoracic
vertebra, where it continues in descending part of aorta (pars
descendens aortae).
The highest point of aortic arch is located behind the
37
manubrium of sternum, in the centre, 1 – 2 cm lower from
incisura jugularis.
The arch of aorta rounds a. pulmonalis dextra, lung trunk
bifurcation and left main bronchus adhering to anteroinferior
