Abstract

AIM OF THE STUDY: To Study the Anatomy (Morphological & Morphometric) Parameters, Variations and Its Clinical Significance of Left Renal Vein. MATERIALS AND METHODS: Dissection Method, 22 Cadavers and 8 Enbloc Specimens, Radiological Method, Multidetector CT Images From 20 Patients. RESULTS: Various Observations that are Noticed were Compiled and Compared With The Previous Studies. The Incidence of Circumaortic and Retroaortic Left Renal Vein Coincides With Most of the Previous Authors Study, Except For Satyapal’s. CONCLUSION: The clinical importance of left renal vein is as follows: The major role in renal transplantation is the limelight as the left side is the preferred site for donor nephrectomies. The knowledge of classification of types of renal venous drainage pattern has surgical and uro-radiological relevance especially in assisting renal angiographers for, selective segmental vein renin assay sampling. The awareness about the presence of retropelvic tributary and / or branch gains important for the urologist during open / laproscopic pyelotomy, pyeloplasty to prevent accidental injury to these structures. The anatomy of termination of left suprarenal vein is important during left adrenal vein catheterization and adrenal hormonal assaying. The knowledge of termination of left gonadal vein is significant to interventional radiologist for doing varicocele embolization procedures and also for surgeons. Ligation of left renal vein is done during aortic aneurysmal and other aortic repair surgeries, in order to gain clear access to aorta while repairing it and so the knowledge of safe limit for ligation is important for vascular surgeons to enable them in avoiding accidental injury to tributaries and collateral circulating channels of left renal vein. Left gonadal artery crossing over the renal vein may be a possible etiological factor for idiopathic varicocele in male and / or orthostatic albuminuria, pelvic varicocele (ovarian (or) broad ligament varicocele) in females, due to compressive effect of it. Prior knowledge of left renal venous variations are important for vascular surgeon, retroperitoneal surgeon, urologist and radiologist so that accidental injury during surgery or missing of the variations during imaging could be avoided. Compression of left renal vein by superior mesenteric artery and abnormal course results in nutcracker phenomenon, results in haematuria, hypertension and pain in abdomen. Compression of gonadal vein results in pelvic congestion syndrome in females, and varicocele in males. As previously pointed out in discussion, there occurs a considerable variation in incidence of certain significant morphological and morphometric parameters of left renal vein, when compared to textbook standards and previous studies and so, The present study which is done without haste and so, it makes the possibility of demonstrating anatomical structures in detail which are not done easily during the surgical procedures. It warrants recognition of these prior knowledge to many therapeutic and research decisions.
