The goiter extended to the bifurcation of the trachea on the dorsal side of the superior vena cava, the
innominate vein, the aortic arch, and the ventral side of the trachea.
It was unlikely that the dilated right atrium was an acute change considering that his left superior pulmonary vein had been delivering excess volume return to the right atrium via the
innominate vein, his entire life.
Successful pacing lead implantation has been reported after angioplasty and stent dilation of superior vena cava and
innominate vein obstructions (16).
Here, we reported a male patient, whose imaging studies revealed an ectopic parathyroid gland, located in the lower part of the superior mediastinum, below the
innominate vein. We performed parathyroidectomy, through a traditional transcervical incision, avoiding more invasive procedures and reducing the cost of treatment.
A large mass encasing the
innominate vein was identified in the anterior and superior aspect of the mediastinum.The mass was found to be in close approximation of the pericardium, left phrenic nerve and the vagus nerve with the fibrous pericardium adherent to serous pericardium.
Hemiazygos continuation to coronary sinus with normal left
innominate vein. Cardiovasc Dis 1975; 2: 325-30.
The TD was located between the internal jugular vein (ventral) and the vertebral vein (dorsal), the ultrasonographic visible part of the TD ranged 3–5 cm distal from the venous angle, where the jugular vein and subclavian vein join as
innominate vein. In healthy volunteers, the TD walls were visualized clearly and the lymph walls were seen to be smooth and continuous.
With type I, having a supracardiac connection (50%), the common pulmonary trunk joins the left vertical vein, the
innominate vein, or the superior vena cava.
B: Coronal CT of the cyst demonstrates its cervical and mediastinal components with splaying of the
innominate veins.
It contains the origins of the Sternohyoidei and Sternothyreoidei and the lower ends of the Longi colli; the aortic arch; the innominate artery and the thoracic portions of the left common carotid and the left subclavian arteries; the
innominate veins and the upper half of the superior vena cava; the left highest intercostal vein; the vagus, cardiac, phrenic, and left recurrent nerves; the trachea, esophagus, and thoracic duct; the remains of the thymus and some lymph glands.
When portions of the subclavian and
innominate veins and superior vena cava cannot be visualized, which as noted is a common situation with US, reliable evaluation can be performed with catheter venography, with a contrast injection into the antecubital vein or via basilic or brachial vein access, with catheterization of the subclavian vein, under fluoroscopic control.
Fistula formation with the common aortic arch, common carotid artery, superior and inferior thyroid artery and
innominate veins have also been reported.3
