Hypoplasia of the inferior vena cava with compensatory azygos–hemiazygos dilatation complicated by superior mesenteric vein thrombosis and small bowel ischemia

Key Points

• This report aims to describe a case involving inferior vena cava hypoplasia and its complications.
• Detailed case analysis of the patient's vascular condition
• Assessment of compensatory mechanisms in the venous system
• Evaluation of associated complications such as thrombosis and ischemia
• Significant dilation of the azygos-hemiazygos venous system was observed.
• Complications included thrombosis in the superior mesenteric vein.
• The patient experienced small bowel ischemia due to compromised blood flow.
