[Aplasia of the inferior vena cava].

A 12-hour-old white female infant is reported who suffered from multiple combined visceral malformations. Inversion of the caecum and ascending colon was noted. An extremely rare finding was the absent inferior vena cava. There was a left-sided Bochdalek's hernia with subsequent hypoplasia of the left lung. Thus respiratory failure immediately after birth required emergency surgery. Besides, a single umbilical artery was found. Manifestations and embryologic background are discussed.
