Introduction And Importance:
Anomalous venous drainage of the right upper lobe into the superior vena cava is an uncommon anatomical variation, typically diagnosed incidentally.
Case Presentation:
We report the case of a 76-year-old male patient undergoing right upper lobectomy via video-assisted thoracoscopic surgery (VATS) for a primary pulmonary adenocarcinoma, combined with a minimally invasive subtotal esophagectomy for an adenocarcinoma of the gastroesophageal junction. During the thoracic procedure, an anomalous venous drainage of the right upper lobe into the superior vena cava was identified intraoperatively. The patient had no prior respiratory symptoms suggestive of a left-to-right shunt. Surgical management was adapted to account for the vascular anomaly.
Clinical Discussion:
We discuss anomalous venous drainage of the right upper lobe into the superior vena cava is an uncommon anatomical variation which may pose significant challenges during thoracic surgeries.
Conclusion:
This case highlights the importance of careful intraoperative assessment of vascular anatomy during thoracic oncologic surgery.

01:19Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

01:11Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
