The use of port-a-caths in adult patients with Lysosomal Storage Disorders receiving Enzyme Replacement Therapy-one centre experience.

Port-a-cath is a widely used device in patients with long-term venous access demand such as frequent or continuous administration of medications such as Enzyme Replacement Therapy (ERT), chemotherapy delivery, blood transfusions, blood products, and fluids. Patients with Lysosomal Storage Diseases (LSDs) often require recurrent courses of ERT. We reviewed our experience of using port-a-caths in patients with LSDs with the focus on challenges and complications associated with these catheters. Among 245 adult patients who were treated with ERT, twenty patients (8.2%) had a port-a-cath inserted due to poor venous access. Six patients were using their first port whereas five other patients had their port-a-caths replaced at least once. The remaining six patients had inactive port-a-caths. The majority of patients with active port-a-caths never missed more than one consecutive infusion, although one patient missed 2 consecutive infusions whilst on holiday. We identified significant gaps in patients' and their families' understanding of the management of port-a-caths and risks associated with them. It resulted in producing a leaflet and designing an educational program for our LSD patients.
