forms an important channel connecting the superior and inferior vena cava.
The 26-year-old patient's specific anomalies included: a persistent left superior vena cava draining into the left coronary sinus, an interrupted inferior vena cava, absent azygos vein
, bilateral bilobed lungs and polysplenia.

In AM patients, the portal venous blood most commonly drained into the inferior vena cava and occasionally into the renal veins, iliac veins, azygos veins
, or right atrium.[sup] In this case, the splenic vein and superior mesenteric vein joined together, drained into the hemiazygos vein, and ultimately entered the superior vena cava through the azygos vein
The nerves of both sides are adjacent to medial arcuate ligament of diaphragm, the upper pole of the adrenal gland and crus of diaphragm, together with the abdominal aorta and hemiazygos vein on left side, inferior vena cava and azygos vein
on the right side.
We then gently pushed the coin upwards and did a small longitudinal incision 3 cm below the azygos vein
, through which the coin was removed.

(b) Infrahepatic IVC drains into the Azygos vein
(black straight arrow) that enters the thorax together with the aorta (star).
Contrast abdominopelvic CT showed an old complete thrombosis of the left common iliac vein, recent complete thromboses of the left venous junctions (external and internal iliac veins, common femoral deep and superficial veins, ascending lumbar vein and various presacral collaterals), dilated azygos vein
, partial eccentric thrombosis of the IVC, approximately 18 mm lower than the flow level of the right renal vein, with a 5mm clot on a length of 27mm, with a reduced caliber on almost its entire length from the origin to the level of the caudate lobe.
In addition to the visualized tissues in this study, at least not precisely, it's possible to observe the right costocervical vein, the right azygos vein
and the frenic nerve (PIGATTO et al., 2008).
(1) Cannulation of the accessory hemiazygos vein is rare but can happen when the accessory hemiazygos vein drains into the left brachiocephalic vein instead of the azygos vein
