Hemi-azygous vein runs in posterior mediastinum with a small horizontal communication with azygous
vein at 9th thoracic vertebra.
(2) With severe SVC baffle obstruction, a dilated azygous
system can be sought.

anterior cerebral artery stenosis," Italian Journal of Neurological Sciences, vol.
Important anatomic considerations in the posterior mediastinum include the descending thoracic aorta, trachea, esophagus, azygous
venous system, and potential spinal involvement.
There was one patient with complete absence of IVC with azygous
It continues between the aorta and azygous
vein until it reaches the fifth thoracic vertebrae.
Invasive strategies in management of high DFT identify: use of high output ICD device, altering the shock vector through RV lead repositioning, manipulation of the superior vena cava coil, additional coil implantation in the azygous
vein, coronary sinus and epicardial space or addition of subcutaneous arrays, the latter rarely used nowadays [18, 19].
Lt sided IVC was found draining in hepatic sinusoids on Rt side and ultimately draining in right atrium (RA) via hepatic veins, Rt sided IVC was draining in RSVC via Azygous
Within the abdomen, the thoracic duct ascends along the anterior surface of the lumbar vertebra, between the aorta and azygous
vein, to enter the thorax via the aortic hiatus in the posterior mediastinum.

vein," Interactive Cardiovascular and Thoracic Surgery, vol.
For example, MRI derived hepatic blood flow parameters and azygous
flow have been shown to correlate with portal pressure  and variceal size , respectively.
