The use of peripherally inserted central catheters (PICCs) represents a major advance for hematological patients, enabling the effective delivery of chemotherapy and/or blood products particularly for prolonged infusions or in situation of difficult venous access. In modern medical practice their use has increased rapidly for several reasons, including ease of insertion, many uses (e.g., drug administration and venous access), perceived safety, and cost-effectiveness compared with other central venous catheters (CVCs).
