Implantation of a totally implanted venous device unexpected discovery of left permanent superior vena cava in a patient with sigmoid colon cancer: a case report.

Persistent left superior vena cava (PLSVC) is an intrathoracic vascular malformation. Sigmoid colon cancer with a left superior vena cava (LSVC) is very rare. Totally implanted venous devices (TIVADs) are commonly used in recurrent chemotherapy for sigmoid colon cancer.

Insertion of a totally implantable vascular access device in a patient with dextrocardia and colon cancer: a case report.

Colon cancer in patients with situs inversus totalis is rarely associated with dextrocardia, and chemotherapy is commonly used for treatment. Central venous access devices are used to administer intravenous fluids and chemotherapy in patients with colon cancer. Compared with peripherally inserted central catheters and Hickman-type tunneled catheters, totally implantable vascular access devices (TIVADs) are safer and more effective.
