Abstract
Introduction The variant courses of blood vessels are very important in considerations for retroperitoneal
surgeries or interventional radiology. The present study attempted to describe a very
rare case of double inferior vena cava (IVC) associated with double left suprarenal
veins (LSRVs) and double right testicular veins (RTVs) in a Thai male embalmed cadaver.
Material and Methods A 70-year-old Thai male cadaver was systemically dissected and observed for the vascular
distributions during gross anatomy teaching for medical students at the anatomy department
of the faculty of medicine of the Khon Kaen University.
Results We found that the double IVCs were connected with the transverse interiliac vein.
While the upper LSRV is a tributary of the IVC, the lower LSRV is a tributary of the
left renal vein. The RTV bifurcates at about the height of the iliac cristae to form
the medial and lateral RTVs, which drain into the right IVC at different heights.
Conclusion All these duplications and associated anomalies are assumed to occur during the embryological
development. These anomalies are rare, but the knowledge about the possibilities of
these anomalies is of great importance during retroperitoneal surgeries, and during
interventional radiology.
