On the right side, the testicular vein drained into the right renal vein and the right testicular artery passed posterior to the inferior vena cava. The left testicular vein was composed of the lateral and medial testicular veins which drained into the left renal vein independently.

Abstract Introduction The variant courses of blood vessels are very important in considera- tions 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. Keywords Results We found that the double IVCs were connected with the transverse interiliac ► double inferior vena vein. While the upper LSRV is a tributary of the IVC, the lower LSRV is a tributary of the cava left renal vein. The RTV bifurcates at about the height of the iliac cristae to form the ► double suprarenal medial and lateral RTVs, which drain into the right IVC at different heights. veins Conclusion All these duplications and associated anomalies are assumed to occur ► double right during the embryological development.

  • Arched Left Gonadal Artery Over the Left Renal Vein Associated with Double Left Renal Artery Ranade a V, Rai R, Prahbu L V, Mangala K, Nayak S R
    Case Report Singapore Med J 2007; 48(12) : e332 Arched left gonadal artery over the left renal vein associated with double left renal artery Ranade A V, Rai R, Prahbu L V, Mangala K, Nayak S R ABSTRACT Variations in the anatomical relationship of the gonadal arteries to the renal vessels are frequently reported. We present, on a male cadaver, an unusual origin and course of a left testicular artery arching over the left renal vein along with double renal arteries. The development of this anomaly is discussed in detail. Compression of the left renal vein between the abdominal aorta and the superior mesenteric artery usually induces left renal vein hypertension, resulting in varicocele. We propose that the arching of left testicular artery over the left renal vein could be an additional possible cause of the left renal vein compression. Therefore, knowledge of the possible existence of arching gonadal vessels in relation to the renal vein could be of paramount importance to vascular surgeons and urologists during surgery in Fig. 1 Photograph shows the left testicular artery along with the retroperitoneal region. double left renal arteries after reflecting the inferior vena cava Department of downwards.

  • Bilateral Origin of the Testicular Arteries from the Lower Polar Accessory Renal Arteries
    Int. J. Morphol., 30(4):1316-1320, 2012. Bilateral Origin of the Testicular Arteries from the Lower Polar Accessory Renal Arteries Origen Bilateral de las Arterias Testiculares desde las Arterias Renales Polares Inferiores Accesorias Eleni Panagouli; Evangelos Lolis & Dionysios Venieratos PANAGOULI, E.; LOLIS, E. & VENIERATOS, D. Bilateral origin of the testicular arteries from the lower polar accessory renal arteries. Int. J. Morphol., 30(4):1316-1320, 2012. SUMMARY: The gonadal arteries (testicular or ovarian arteries) emerge normally from the lateral aspect of the abdominal aorta, a little inferior to the renal arteries. Several other sites of origin of these arteries have been recorded with the renal and accessory renal arteries being the most common. In the present case report, the testicular arteries originated from the lower polar accessory renal arteries in both sides. The testicular veins followed had the usual origin and course, while an accessory renal vein was observed only in the right side. These anomalies were combined with an abnormal left ureter exiting from the lower pole of the kidney. Only one male cadaver among 77 adult human cadavers of Caucasian origin presented this set of variations (frequency: ≤ 1.3%). Variations of renal and gonadal vessels are important, as their presence could result in vascular injury of any accessory or aberrant vessel if the surgeon does not identify them. KEY WORDS: Gonadal arteries; Kidney; Ureter; Abdominal aorta. INTRODUCTION The gonadal arteries (GA), described as one of the anatomic variation of the renal arteries (RA) (Tarzamni et paired branches of the abdominal aorta (AA), emerge al., 2008) with an incidence, which ranges from 8.7 % to normally a little inferior to the renal arteries (Standring et 75.7 % (Satyapal et al., 2001).

The right testicular artery arose from the right accessory renal artery, which originated from the ventral aspect of the abdominal aorta. The left testicular artery originated from the ventral aspect of the aorta in almost the same horizontal line as the right accessory renal artery, just below the superior mesenteric artery and 1.79 cm, above the origin of the renal arteries. The right vein drained into the right accessory renal vein instead of the inferior vena cava, while the left testicular vein drained into the left renal vein. The presence of variation of both the testicular arteries as well as the testicular vein is seldom seen together.

Despite being considered an endemic species, little is known about the hoary fox as it is one of the seven less studied canids in the world. Thus, this study aimed to describe the anatomy of the abdominal aorta artery of the hoary fox and to compare it with the pre-established literature data in domestic canids. For this purpose, we used two adult hoary foxes without definite age. We collected the corpses of these animals along roadsides of Catalão-GO, being later fixed and conserved in a 10% formalin solution. The results showed that the abdominal aorta in hoary fox is at the ventral face of the lumbar region vertebral bodies, being slightly displaced to the left of the median plane. The first branch is visceral, named celiac artery, followed by a paired parietal branch: the phrenic abdominal arteries.
