As for the postoperative complications of surgery for substernal goiters, they have been reported to include pneumonia, atelectasis, pneumothorax, pleural effusion, and innominate vein injuries, etc., which seem to be characteristic complications of mediastinal surgical procedures [16].
First, because of the anatomic findings: our patient presented with an exceptionally infrequent variant of PAPVC, a left-sided aberrant superior pulmonary vein draining into the left innominate vein. Also, our patient's echocardiogram revealed a large right atrium without an atrial septal defect.
In left sided PAPVC, vertical vein was ligated at junction of innominate vein and proximal vertical vein was anastomosed with left atrial appendage.
The most common area of lead related fibrotic stenosis is the junction between the superior vena cava and innominate vein. Thrombosis or stenotic lesions may also occur in the axillary, subclavian and innominate veins, or in the superior vena cava, and silent lesions have been reported to be relatively common.
On the right side of the neck, the right lymphatic duct conveys the lymph from the head and neck, the upper extremity and the right side of the thorax to the right innominate vein. Here, the duplicated thoracic duct on the left side opened directly into the inferior vena cava.
During the course of surgery, while the patient's chest was being opened, the innominate vein was torn.
On the contrary, when the tip was in a different location, such as the innominate vein or the innominate/SVC junction, incidence of thrombosis was as high as 70%.
Right subclavian vein venography demonstrated the absence of RSVC and drainage of right subclavian vein into the PLSVC via the innominate vein [Figure 1]a.
This approach offers a longitudinal view of intrathoracic segment of the SCV reaching (via the innominate vein on left side) the IJV at the level of the Pirogoff confluent.
In 80% of cases, there is RSVC and in 35% of cases, the innominate vein is present.
