Indications and complications of intravenous devices for chemotherapy.
Vascular access devices (VADs) are frequently used in patients with cancer. Vascular access devices can be divided into external catheters and subcutaneous venous access ports. Each type of device has its advantages and disadvantages, but the indications and optimal use of specific VADs remain to be defined. There are multiple complications of VADs but, with the exception of catheter-related bloodstream infections and thrombosis, most complications are rare. The use of VADs impregnated with antibiotic reduces the rates of catheter colonization and catheter-related bloodstream infections as compared with the use of unimpregnated catheters for short-term use. Thrombosis remains a major complication of VADs, and prospective, controlled studies are needed to clearly define the risk factors, natural history, and optimal treatment of this complication.
