Presentation of a True Aneurysm of the Left Antecubital Vein

A venous aneurysm is defined as a dilatation of a localized segment of vein occurring in most major veins, affecting the lower extremities the most and the upper extremities the least, occurring equally between sexes at any age. A 62-year-old man was referred to our polyclinic's cardiovascular surgery department. He presented with a 27-year history of a swelling in the left antecubital fossa. He complained of its increase in size, worsening pain, and paresthesia. Examination of the left antecubital fossa revealed a painless, soft, nonpulsatile mass 3-4 cm in size with no palpable thrill. A Duplex ultrasound scan of the mass displayed an aneurysm of 4 x 3 x 3 cm in the left antecubital vein. His past medical history included repeated nephrolithotomies. The aneurysm was dissected and excised. The patient was discharged on the second postoperative day. Surgery should be performed in cases such as the presence of local discomfort, swelling, and paresthesia for the relief of symptoms.
