Abstract

Background. Detailed knowledge of the ovine jugular vein anatomy and physiology is a prerequisite for proper use of sheep as teaching or an experimental model in interventional radiology. Material and methods. Ascending and descending jugular venograms in tilted position were done in 25 sheep to evaluate the jugular vein (JV) size and anatomy of its valves. Results. The average maximal diameter of 50 JVs was 13.34 ± 1.18 mm. Each vein contained an average of 4.36 ± 0.98 valves. All valves were competent and 96.3% were bicuspid. Conclusions. Because of similarities between ovine JV and human femoral vein in regards to diameters, number and type of valves and function of their valves with increased central and hydrostatic pressure, the ovine JV is a good model for evaluation of creation of JV valve incompetence, percutaneous valve transplantation and evaluation of prosthetic valve devices.
