Abstract
AbstractA 12‐week‐old alpaca cria, that had been managed conservatively for a subluxation of the third and fourth cervical vertebrae (C) and possible C6–C7 subluxation identified several weeks previously following trauma at birth, was presented for investigations of acute onset tetraparesis. During investigations with computed tomography, a persistent left cranial vena cava, with an unusual phenotype, was incidentally identified with concurrent absence of the right cranial vena cava. The azygous vein could be seen crossing over the mediastinum to join the persistent left cranial vena cava, which continued caudally, passing left lateral to the heart and emptying into the caudal vena cava at the level of the diaphragm.
