Venous aneurysms continue to be one of the little studied sections of modern vascular surgery. Messages on the occurrence of this pathology in the medical literature are very few and describe extremely rare clinical cases, localized mainly in the deep veins of the lower extremities and leading to thromboembolic complications. Single publications describe venous aneurysms localized in superficial saphenous veins. The etiology and pathogenesis of this disease currently continues to cause debate. The article provides a literature review on this rare surgical vascular pathology, presents its own clinical observation, discusses the issues of diagnosis and treatment options for this disease.
