Chemotherapy is an essential component of breast cancer treatment. Frequent intravenous injections may lead to phlebitis and limited venous access, therefore implantable venous ports are increasingly used. The choice of port placement side in breast cancer patients is controversial, especially when mastectomy or radiotherapy is planned. This retrospective cohort study compares one-year patency, complications (infection, thrombosis, skin necrosis), and functional outcomes of ports implanted via the right internal jugular vein in patients with right versus left breast cancer.
Female patients with breast cancer (right or left side)

Prior neck surgery or radiotherapy involving right jugular area
Incomplete medical records
All breast cancer patients receiving right internal jugular venous port implantation in Gorgan medical centers (2017-2024).
