Venous variations are uncommon and usually hard to identify, and basilic vein variation is particularly rare. Basilic vein variation usually presents without any clinical symptoms and is often regarded as a benign alteration. This case was a patient with congenital basilic vein variation encountered during surgery for an infusion port.


We documented and analyzed an uncommon anatomical variation in the basilic vein encountered during arm port insertion. This peculiarity has hitherto remained undescribed in the literature. We offer remedial strategies for addressing this anomaly in the future and precautionary measures to circumvent its occurrence. We conducted a comprehensive review of analogous cases in the literature, offering pertinent therapeutic recommendations and solutions, with the aim of enhancing the efficacy and safety of future arm port implantations.


Venous variation is rare and requires detailed intraoperative and postoperative examination to ensure accuracy, so as not to affect subsequent treatment.

Keywords: Totally implantable venous access ports, Arm ports, Venous variation, Postoperative breast cancer, Systematic review, Case report

Core Tip: Venous variation refers to structural malformations caused by abnormal development of venous vessels. At present, the etiology is still unknown. In the process of implanting the arm port for a tumor postoperative patient, we found and reported a case of successful treatment of basilic vein variation encountered during the operation, which can provide a reference for such cases in the future.
