The presented knowledge of anatomical variation and abnormali-ties of vertebral circulation can improve the accuracy and "safety" of the surgical procedures in this region, help to determine the range of surgical approach and avoid associated complications. The radiological examinations using 3D CT, DSA reveal unlimited observation of anatomical structures in contrast to studies based on cadavers, and can complement the morphometry in anatomical preparations.

Persistent left superior vena cava is an uncommon abnormality of the venous system. Most commonly, it is diagnosed incidentally during central vein catheterisation on the left side or pacemaker implantation. We present the case of a patient with persistent left superior vena cava, which was diagnosed after the attempted insertion of tunnelled haemodialysis catheter through the left internal jugular vein. The presence of the persistent left superior vena cava was confirmed by cardiac echography and angio–computed tomography scan. The 19-cm long tunnelled haemodialysis catheter was inserted into persistent left superior vena cava through the left internal jugular vein with good long-term function.

3&9As are commonly detectable during evaluation angiography prior to RE, have a variable angioanatomic origin, and should be prophylactically occluded to prevent complications.
