Implantation of central vascular access devices for intravenous administration. Complications and consequences for a patient on the example of a clinical case

Implanted central vascular access devices for intravenous administration of drugs are widely used in cancer patients who require long-term access, specific chemotherapy and parenteral nutrition. Installation of central vascular access devices solves the problem of venous access, but, unfortunately, it can lead to complications, including serious and irreversible ones. Here is a clinical case of cancer in a 49-year-old female patient who was implanted with a vascular access device for intravenous therapy. The incorrect and undiagnosed insertion of the vascular access device in the subclavian artery and also neoadjuvant polychemotherapy sessions led to myelomalacia with the subsequent development of myeloradiculopathy, the emergence and development of persistent neurological disorders. After radiological diagnosis and verification of this complication, percutaneous transluminal angioplasty with single stenting and removal of the central vascular access device was performed. The article presents complications with the insertion of central vascular access devices and discusses in detail a clinical case of complication and methods for its solution when this device is incorrectly implanted in the artery.
