Vascular access devices (VADs) are frequently used in patients with cancer.
Vascular access devices can be divided into external catheters and subcuta
neous venous access ports. Each type of device has its advantages and disad
vantages, 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 complicatio
ns are rare. The use of VADs impregnated with antibiotic reduces the rates
of catheter colonization and catheter-related bloodstream infections as com
pared with the use of unimpregnated catheters for short-term use. Thrombosi
s remains a major complication of VADs, and prospective, controlled studies
are needed to clearly define the risk factors, natural history, and optima
l treatment of this complication. Curr Opin Oncol 2000, 12:303-307 (C) 2000
