Great saphenous vein (GSV) is the longest vein in the body originating from the dorsum of the foot at medial malleolus to the level of groin skin crease. It is one among the clinically significant superficial veins of the lower limb. Double or duplication of GSV is considered to be one of its rarest variant forms, which might be often mistaken with the accessory saphenous vein. The overall incidence of duplicated GSV is reported to be 1%. We report herein, a unilateral duplication of GSV with its morphological and clinical perspectives. The major clinical complication that is often encountered from its duplication is recurrent incompetence of the GSV, which predisposes varicosity. Therefore, a thorough knowledge of venous anatomy is important for clinicians and sonographers.
IntroductionThe left kidney is supplied by the left renal artery, which is a branch of the abdominal aorta and drained by left renal vein, which is a tributary of the inferior vena cava. This article reports a case of morphological and vascular variations of the left kidney.
Case reportDuring dissection classes for medical undergraduates, we observed morphological and vascular variations of the left kidney in a male cadaver aged approximately 65 years. Hilum of the left kidney was situated on the medial half of its anterior surface. The left renal artery made a prominent downward curve at its origin and then coursed upward and to the left. It divided into two major branches before entering the kidney. The left renal vein had two divisions: an upper and a lower. The upper division was formed by a union of two veins, and the lower division was a single vein. The upper division and lower division had a crisscross arrangement before they united to form a single vein. Conclusion Knowledge of the morphological and vascular variations of the kidney reported here is of importance to urologists, radiologists, endocrinologists and surgeons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
