Unusual case of subxiphoid uniportal VATS right upper lobectomy in a patient with interrupted inferior vena cava with azygous continuation

Interrupted IVC (also known as Azygos continuation of the inferior vena cava) is a relatively uncommon congenital condition with prevalence 1.5% (0.2–3%) of the general population (Bass et al.). Although it’s usually asymptomatic condition, splenic or cardiac abnormalities could be associated (Hardwick et al.). Incidental diagnosis during prenatal ultrasound screening or by routine imaging is the most common scenario. Special attention is required during right side thoracic procedures surgical resections in order to avoid scarifying the azygos vein that could lead to fatal results (Effler et al.). We herein report a video documented case of right upper lobectomy and mediastinal lymph node dissection for non-small cell carcinoma of lung in a patient who had interrupted hepatic segmental branch of the IVC. The procedure was performed via the subxiphoid uniportal VATS approach.
